I’m standing up a brand-new, production-ready DevOps platform for a container-based microservices e-commerce application and I want it to mirror the rigor you’d see in large enterprises. Everything will run on AWS and be orchestrated by Kubernetes, with Jenkins driving the CI/CD lifecycle. Scope You will architect, implement, and document the full path from code commit to live traffic. That means infrastructure as code, automated pipelines, immutable deployments, GitOps workflows, comprehensive observability, airtight security controls, and high-availability design—all delivered as a working, demonstrable environment. Key elements I expect • AWS foundation (networking, identity, security, cost-aware resilience) • Kubernetes cluster production-hardened fo...

Real‑Time Market Replication Platform (API Integration + Matching Engine) We are building a real‑time market replication platform that synchronizes external market data through API integration and manages user balances, exposure, and order execution through a custom matching engine. The platform will include: API data ingestion (real‑time external market feed) Liquidity mirroring (synchronized price ladder and market depth) Matching engine (order execution, partial fills, queue management) Wallet ledger (balances, transactions, exposure tracking) Risk/exposure logic (per‑user and global limits) Admin tools (market controls, user management, reporting) Audit logs (full traceability of operations) We are looking for experienced backend developers or small teams with strong knowledge of: dis...

I’m building a secure, privacy-first mental-health support platform inspired by BetterHelp and want an experienced partner to take it from concept to launch. The very first release must be fully functional in English, yet coded so additional languages can be rolled in without refactoring. Core experience The product centres on live, one-to-one HD video therapy sessions, real-time messaging/chat, and a completely automated appointment-scheduling flow that keeps therapists’ calendars and client reminders in sync. I also need an AI layer that can surface self-help resources, suggest next-step actions, and flag potential crises for clinical review—all while keeping user data encrypted at rest and in transit. Technical expectations Please architect for scale (micro-service...

I’m expanding our software engineering team here in Pakistan and want two strong full-stack engineers who are equally comfortable in ASP.NET and React.js. On any given week you might spin up a brand-new microservice in .NET 7, wire its UI in React + TypeScript, or dive into an older codebase to refactor and patch issues. Clean, well-documented commits and a habit of writing unit tests are essential because we ship continuously. Your day-to-day work will cover both building new applications and maintaining existing ones, and you’ll often be the first line of technical support when something goes bump in production—so clear, proactive communication is as important as your code. We collaborate in English on Slack and track work in Azure DevOps; experience with those (or sim...

I need a senior engineer who has already wired multiple social networks into a single product and can show live links or repos that prove it. My platform must speak to X (Twitter), LinkedIn, Instagram, TikTok, Facebook, Threads, Bluesky, YouTube, Pinterest, and Google Business Profiles. Scope of integration • Content posting – scheduled and instant. • Analytics & reporting – reach, engagement, followers, plus any network-specific metrics you can expose. • Secure user authentication via each network’s recommended OAuth flow. Everything has to roll out at once, so I’m not looking for a phased approach: all ten connections have equal priority and need to be production-ready as soon as possible. I can supply API keys and sandbox accounts on ...
