Express JS Jobs

I need like Coach Surfing web + mobile app. I have an existing Flutter mobile application that already communicates with a Node.js backend. I now want to push it further: tidy up the current codebase, add several new screens, tighten the API layer on the server, and introduce a small yet meaningful AI feature (think personalised recommendations or basic natural-language queries—exact scope to be agreed together). Here is what I need from you: • Flutter work – polish the present UI, wire in the new screens I will supply as Figma frames, and be sure state management stays clean and predictable. • Node.js work – extend the current Express API, connect the new endpoints to MongoDB, and add role-based authentication so the app can distinguish between guest and...

What the work covers: • Security: fixing authentication gaps, hardening API routes, correcting middleware configuration • Performance: eliminating N+1 database queries, optimising indexes, improving caching • SEO: server-side rendering improvements, structured data, metadata • Code quality: removing dead code, resolv...

I’m updating my portfolio site for InventoryGPT and need a fresh hero section that feels truly minimalistic while instantly telling visitors what we do: use AI to predict demand and optimize stock levels. The copy is ready, so your focus is on layout, typography, spacing, and a single standout call-to-action button. A subtle illustration or abstract graphic is welcome if it stays light and uncluttered, but the design must keep plenty of white space and direct attention straight to the headline and CTA. Deliverables • Figma (or comparable) source file with well-named layers • Desktop and mobile versions • Export-ready SVG/PNG assets for any custom graphics • Quick hand-off notes covering fonts, colours, and spacing Acceptance criteria 1. Hero sho...

Cloud360 is moving into Phase 2, a cycle dedicated solely to squashing the bugs that surfaced after launch. I’ll hand you a clearly documented backlog—steps to reproduce, log excerpts, and a link to the Git repository—and expect clean, well-commented patches submitted via pull request. Each fix must be accompanied by unit tests and must pass the existing CI pipeline before we promote it to our staging environment. The stack is a typical cloud-native mix of Node.js, React, PostgreSQL, Docker, and AWS services, with automated testing through Jest/Mocha and a CI/CD workflow. If you are comfortable diagnosing issues in this ecosystem and can work iteratively while keeping an eye on regression risk, you’ll fit right in. Deliverables • Patched source code for eac...

I'd be interested to know how you envision the website's design. Therefore, I would suggest that you first create a screen design for us – for example, for the homepage, a category page, and a product detail page. This will allow me to better assess whether your design style matches what I envision for the site. I want the new shop in JTL. It's important to me that the design is technically sound, without unnecessarily bloating the HTML and CSS files. The site should load quickly, be Google-compliant, and offer good usability for users. Nevertheless, I am particularly interested in how you would implement the page structure and design to match our corporate design and brand identity. Therefore, it would be important for me to see some initial drafts from you bef...

I need you to build a fast, scalable, mobile-first web application with React 18 and Next.js. The backend will run on Node.js and persist data in a MySQL database, so you’ll design the schema, wire it up through an ORM such as Prisma or Sequelize, and make sure it performs well under load. Clean UI/UX is critical: every screen must be responsive, intuitive, and accessible across modern browsers and devices. Server-side rendering or incremental static regeneration in should be used where it improves speed and SEO. Security is non-negotiable. Implement a solid authentication flow (email/password at minimum) with hashed credentials, secure session handling, and CSRF protection. If you can propose additional layers like social sign-on or 2FA, let me know how you’d roll them out....
