I want to turn my “farmesr” concept into a practical solution that measurably reduces costs across my operation. Rather than a standard website, mobile app, or graphic design piece, I’m after a tailored approach that pinpoints inefficiencies, automates repetitive work, and streamlines day-to-day tasks. Here’s what I need: • An initial discovery session to understand the current workflow and gather any data you require. • A concise analysis that identifies the biggest cost drains. • A functional prototype—whether that ends up being a lightweight web dashboard, an internal tool, or another format you recommend—that tackles those cost issues head-on. • Clear documentation so I can track savings, expand features later, and onbo...
We have a newly built WP site in Elementor. Would like to make few changes in ELementor and get the site ready to launch.
I want a small API-driven utility that hooks into Angel One and automates my option entries exactly the way I trade them. Here’s the workflow I need: • I will trigger a fresh buy order in an option at a user-defined price that is higher than the current market. • Before sending the order I’ll type in three numbers: Stop-Loss, Target-1, and Target-2 (all specific price points). • The moment Target-1 is filled, the tool must automatically book 70 % of the position, raise the Stop-Loss on the remaining quantity to my entry cost, and let the rest run. • If Target-2 hits, close the balance; if price reverses to the new Stop-Loss, exit there instead. Build this with Angel One’s API integration so the logic executes server-side or, at minimum, from a ...
I run a WordPress store that needs a quick tidy-up in three spots: ***** It;s a remote job cannot provide access to WordPress , if you agree to do it remotely then just knock. 1) Dual currency must work flawlessly. I already use “Currency Switcher for WooCommerce”, and it should let shoppers toggle between Bangladeshi Taka and US Dollar across every storefront view, cart, checkout and order email. 2) Product pages currently load without any price. Once the currency issue is resolved, the correct price (in the chosen currency) should display instantly on each single-product page. 3) On the About Us, Privacy Policy and Terms & Conditions pages a Woo sidebar is still showing the Category widget; I want that gone so those pages stay clean. Please make the adjustments direc...

I already coded the front-end of a simple task-manager in Python and have uploaded all current files for you. I now need the back-end logic brought to life so the app is fully usable. Here’s what still needs doing: • Hook up the existing login page so users can authenticate and reach the dashboard. • Build a clean “Create Task” flow (form, validation, save). • Store everything in a lightweight SQLite database that ships with the project. • Add three role levels—Admin, Regular user and Guest—so permissions are enforced automatically (e.g., only Admins manage all tasks, Guests view-only). I’m keeping the stack simple: pure Python, standard libraries where possible, and SQLite for data. The UI files are ready; you can refactor ...
I’m launching a brand-new online store and need a developer who can take the entire build from concept to production. The core requirement is a robust product catalog with fast, intuitive search so shoppers can find items quickly on both desktop and mobile. A modern, responsive UI is non-negotiable, and the codebase must be clean, efficient, and easy to scale as my inventory grows. I’m open to the stack you’re most comfortable with—whether that’s React + Node, PHP/Laravel, or another proven e-commerce framework—so long as it delivers solid performance and is easy for me to maintain. Clear communication is important; I’d like short, regular updates and well-documented code so future tweaks are straightforward. Deliverables • Fully functional ...

I need a reliable way to feed real-time location updates from our AVL truck-tracking platform straight into a Google Sheet, refreshing automatically every 30 minutes. The AVL system exposes the data, but I don’t yet have the script or connector that will pull it, parse it, and drop it into the correct columns in Sheets. Here’s what success looks like to me: • A Google Apps Script, Python micro-service, or other lightweight solution that calls the AVL API/webhook on a 30-minute schedule. • Latitude, longitude, timestamp, truck ID, and any additional fields you can surface neatly appended (or updated) in the Sheet without manual intervention. • Clear instructions so I can deploy, adjust the interval later, and add trucks as our fleet grows. • A quick li...

I’m ready to launch my very first YouTube Ads campaign and need an experienced hand to guide the process from zero to live. My goal is simple: increase sales of the best-selling products in my Shopify store. I already have product visuals and copy; what I’m missing is the technical and strategic know-how to turn those assets into profitable video ads. You’ll be responsible for connecting the dots between Shopify and YouTube so the campaigns run smoothly and every conversion is tracked. I’d like clear advice on audience targeting, creative formats, and daily budget pacing, plus a walkthrough so I understand how to optimise and scale once the ads are live.

I need someone who knows the theme inside-out and can push code to production quickly without breaking anything.

The admin review feature on my Laravel-based site already stores entries correctly in the database, but those reviews never appear on the live product page. I need a single, focused fix that renders each saved review directly under the product description—no tabs, pop-ups, or extra filters. Your code must stay fully compatible with my existing Laravel/PHP stack, be clean enough for easy future maintenance, and arrive fast. When you respond, let me know how quickly you can turn this around, what it will cost, and point me to a similar frontend-display bug you’ve resolved so I know you’ve done this before.

I’m taking a new Solana-based DeFi platform from whiteboard to main-net and I need a senior full-stack blockchain developer who can own the entire build. The first protocol on our roadmap is a staking module that pays a fixed daily return. Everything will be written in Rust using the Anchor framework so the program stays upgrade-safe and thoroughly testable. You’ll design the on-chain architecture, code the smart contracts, write exhaustive unit and integration tests, and wire the program into a lightweight web front end. I already have the tokenomics model and UI wireframes; what’s missing is production-grade code and a clean deployment pipeline that can promote from devnet to testnet and finally to main-net without drama. Key deliverables: • Anchor-based staking ...
I’m building a fully-featured smart-contract platform on Solana and need an experienced full-stack blockchain developer to take it from architecture to main-net launch. The core of the work revolves around DeFi protocols—think staking, yield farming, and liquidity-pool mechanics—implemented in Rust with the Anchor framework so the contracts remain upgrade-safe and easily testable. Beyond writing the on-chain programs, I also want a minimal front-end (React or Svelte is fine) that connects through wallet adapters such as Phantom and Solflare, allowing users to interact with the contracts, sign transactions, and view real-time analytics pulled via WebSockets. Security is non-negotiable: please follow best practices for Solana audits, add property-based tests with Anch...

I need a lightweight Grasshopper definition that generates a clean Voronoi pattern I can fold into an architectural origami structure. I will import the script into Rhino myself, so please keep the solution straightforward—no plug-ins beyond standard Grasshopper components. The core requirements are: • Produce a planar Voronoi layout that I can quickly tweak by moving a few control points. • Add simple crease lines or panel edges so the geometry naturally lends itself to an origami-style fold. • Output the result as both a Grasshopper file (.gh) and an optional baked mesh or surface in Rhino so I can test it on a façade-sized panel. A brief note explaining which sliders control cell density and overall scale is all I need. No advanced optimisation or fabri...
I want to launch five separate e-shops for auto parts under one OpenCart installation using the built-in Multistore feature. Each shop will live on its own domain, share the same product catalog, and carry its own logo, colors, and language settings, yet everything must be managed from a single admin panel. Here is what I need from you: • Install or configure the latest stable OpenCart on my server and activate Multistore. • Apply a clean, modern responsive theme to all five storefronts, adjusting basic branding (logo, palette, favicon) per site. • Integrate a robust product-filter extension that lets shoppers drill down by car make, model, year, and engine type. Speed and accuracy matter; the filter must appear on category and search pages and update results without f...
I already run a Laravel-based HRMS (PHP 8.x) and need to bolt on a full Performance Management module without disturbing the rest of the codebase. The current stack uses JavaScript, CSS, LESS and clean Laravel MVC conventions, so you should feel at home if you work comfortably in that ecosystem. What I’m after is a self-contained module that seamlessly plugs into the existing system and covers three core capabilities: • Goal setting & real-time tracking • 360-degree feedback workflows • Structured performance reviews with rating, comment and document upload options The new tables, controllers and UI components must follow the same coding standards and front-end styling already in place. Routes must respect the middleware we use for role-based access, and a...
I am putting together an AI–driven metaverse and need a full-stack blockchain developer who can take the concept from rough ideas to a live, scalable dApp on Ethereum. You will own the smart-contract layer (Solidity, ERC-721/1155, marketplace logic) and the back-end that glues it to the front-end our web3 developer is already crafting. The core objective is to let everyday users enter the world, interact with AI-powered features, and manage on-chain assets without friction. What makes this project interesting is the blend of disciplines: on one side we have generative AI that animates avatars and worlds; on the other, rock-solid Ethereum contracts that safeguard ownership and transactions. You will architect both layers so they talk to each other smoothly, write gas-efficient code, ...
Hello I’m in the final stretch of launching an ICO/IDO/DEX and now need a seasoned blockchain developer to complete the platform-side integration with Binance Smart Chain (BSC). All core smart contracts are written and audited; what remains is wiring everything into a seamless, production-ready experience on BSC so users can purchase, swap, and stake the token without friction. Scope • Connect the existing Solidity contracts to our React/ front end through • Configure PancakeSwap liquidity pools, farm, and staking interfaces so they surface correctly in our dApp. • Set up BSC node endpoints, event listeners, and transaction handling to keep on-chain and off-chain data in sync. • Deploy final contracts with Hardhat/Truffle scripts, verify them on BscSca...
I have a fresh project that must be built with React and the latest version of Next.js. My aim is to get a production-ready codebase that is fast, maintainable, and ready for future scale. You will take charge of the front-end architecture, bring in best-practice patterns, and turn the designs and requirements I provide into polished, tested pages.
Hello We are building a decentralized exchange on Binance Smart Chain and need a senior engineer to take full ownership of the web client and its smart-contract hooks. The platform will offer token swapping, liquidity pools, and staking from day one, so the codebase must be modular and production-ready. The frontend stack is React complemented by Redux for state and Material-UI for the component layer. You’ll connect wallets (MetaMask, WalletConnect, etc.), surface real-time pool data, and wire every action to the underlying contracts. If you’re comfortable refining or extending the Solidity, even better—we can iterate together on the AMM logic for optimum gas efficiency. Deliverables • Responsive React interface with swap, pool, and staking screens fully wired t...

I’m looking for a simple JavaScript snippet that automatically clicks two specific buttons on a static HTML page once every 24 hours. Key points • The page is strictly static—no frameworks or authentication layers involved. • The buttons can be uniquely targeted by their class name. • No pop-ups, alerts, or additional interactions need to be handled. Deliverable • A lightweight, well-commented script (pure JS) that: – Locates the two buttons by class name. – Triggers a click on each of them exactly once every 24-hour cycle. – Includes a concise note on how to embed or reference the script in the page. That’s all I need—just a clean, minimal solution that does the job reliably.
I need the search experience on my Shopify store to look and behave exactly like the one on zarahome.com. The moment a visitor clicks into the field, real-time suggestions must appear, and as they type, the drop-down should update instantly, always showing four product cards (image, title, price) that mirror Zara Home’s spacing, typography and hover effects. The job is purely front-end on Shopify: deliver a Liquid/JavaScript snippet—or an app-level solution—that plugs into my current theme without breaking anything else, inherits my store’s fonts and colours, and remains fully responsive on mobile and desktop. No third-party branding, no style drift; the visuals, transitions and loading behavior have to feel indistinguishable from the reference site. Acceptanc...

I have a stack of paper forms that need to be converted into a smooth, searchable workflow. What I need is an online form—Google Forms works perfectly—that mirrors every field on the original documents and funnels each submission into a live spreadsheet. The finished form must: • Accept file uploads so respondents can attach scans or photos. • Trigger automated email notifications—one confirmation sent to the person filling it out and one alert sent to me. • Enforce solid data-validation rules to stop incomplete or badly formatted entries. Once the form is built, share the link with me for testing. When everything works as intended, provide a short hand-off guide showing how I can tweak questions, adjust validation, and access the collected responses.
I already store all of my shipment and maintenance records in Google Sheets; now I need those raw rows turned into a clear, interactive dashboard. The focus is strictly on performance metrics—most importantly maintenance downtimes and shipment accuracy—so that I can see, at a glance, how reliably the fleet is running and how often we hit promised delivery targets. Everything must stay within Google Sheets. I’m imagining a streamlined file where the existing data feeds a transformation layer and, ultimately, an eye-catching dashboard tab. Dynamic charts, scorecards, and slicers that refresh automatically as new rows are added will make the sheet truly useful to my team. Feel free to incorporate QUERY, ARRAYFORMULA, pivot tables, and—if needed—lightweight Apps ...
