Jawad HassanFull-Stack Engineer · Codebase Rescue · Figma to React · Next.js · AI
Most teams call me when an app already exists and is not working — a dashboard rendering blank, a design that never became a frontend, a repo whose developer stopped replying. I read what is there, tell you what is salvageable, and finish it. I also build from zero when that is the right call. Five-plus years across SaaS, e-commerce, and AI tools.
What you can hire me for
— what I do mostCodebase Takeover & Bug Fixing
A repository, partial documentation, and nobody who understands it. I read the existing architecture first, tell you honestly what is salvageable, then finish it.
Figma to React
You have a design and no frontend. I turn a Figma file into a working React or Next.js interface — reusable components, accurate spacing, and responsive behaviour that holds on real devices.
AI-Built App Rescue
Your app was built with Lovable, Bolt, v0 or Cursor. It worked in the demo. Now it breaks with real users, real data, or a real deploy — and nobody on the team wrote the code.
White-Label Development for Agencies
Extra engineering capacity under your brand. I build React, Next.js and Shopify app work for your clients, under NDA, and your client only ever deals with you.
Next.js Development
I build and ship production Next.js applications — App Router, server components, ISR, and the performance work that keeps them fast after launch.
MVP Development
I take an idea to a deployed product you can put in front of real users — frontend, backend, auth, payments, and deploy, built by one person who owns the whole thing.
Shopify App Development
I build Shopify apps that survive real merchant scale — embedded Remix and Polaris admin UIs, webhook pipelines, and storefront widgets that do not slow a theme down.
AI Integration
I put LLM features into products that already have users — retrieval pipelines, streaming interfaces, evaluation, and the cost and failure handling that demos skip.
Products I built
— shipped soloCodexGenAI
An AI content studio for creators and teams: generate multi-slide carousels, schedule posts across platforms from a visual queue, and track engagement with sentiment analysis. Designed, built, and deployed end-to-end.
HireOS
An AI resume-optimization platform — tailors and rewrites a resume against a target role, renders clean PDFs, and ships with a companion Chrome extension. Built solo end-to-end, with five AI providers behind a bring-your-own-key model.

A community platform for visa workers in the US — connect with peers, get help, and a built-in marketplace. Community features and real-time interactions.

Psychology-backed digital tools for dating anxiety — an interactive web app of guided exercises that help users calm nerves and make steadier decisions.

A UK visa & immigration services platform — guided application flows and multi-step forms that turn a confusing process into a clear path.
