I help startups and product teams build SaaS applications, add features to existing products, modernize legacy codebases and integrate AI into real business workflows. I’m a Full-Stack Developer with 6+ years of experience across SaaS, fintech, mobile and blockchain applications. My core stack includes React, Next.js, Node.js, TypeScript and Ember.js, with additional experience in Vue.js, Nuxt.js, Remix, NestJS and React Native. I can help with: • Full-stack SaaS and MVP development • AI-powered applications and custom AI features • AI chatbots, RAG systems and LLM API integrations • Embeddable chatbots connected to business data • React, Next.js, Vue.js, Nuxt.js and Remix development • Node.js, Express and NestJS backend development • Ember.js migrations, upgrades, maintenance and debugging • REST API and GraphQL development • Stripe, PayPal and Plaid API integrations • Fintech dashboards, payments and transaction workflows • React Native applications for iOS and Android • WebSockets, Socket IO and real-time features • Web3 wallets and smart contract integrations • PostgreSQL, MongoDB, Firebase and Supabase • AWS, Vercel, Docker and application deployment I’m comfortable joining an existing team, understanding an unfamiliar codebase and solving problems without turning every assignment into a complete rewrite. I can also take a new product from early requirements through development and deployment. I have completed several AI-powered applications. One recent project was an embeddable chatbot platform that allows businesses to add a chatbot to their own website. The chatbot connects with the company’s stored data, allowing users to ask questions about sales, performance and other business information in plain language. My previous work includes SFOX, Outdoorsy, CQR Vault, TenderFi, Zahnymous and GOTO App. Across these projects, I have worked on Ember.js modernization, trading interfaces, payment flows, booking systems, real-time data and blockchain integrations. I started my career in design, which still helps me turn Figma designs into responsive, accurate interfaces. I pay attention to the details that often get lost between design and development. If you already have a codebase, send me the technology stack, the current issue and what you want to achieve. If you’re building something new, share the requirements and I’ll help you define a practical first step.

Got a product that works in a demo and falls over with real users on it? That is the thing I get called in for. Eight years in, 100% Job Success and Top Rated Plus, and what I am actually best at is taking over a live system and restructuring it without stopping the roadmap. Most of my work is React, Next.js, TypeScript, Node and Postgres. Last year that meant a consumer AI product at around a thousand daily users, where page load went from 3s to 1.5s and the site finally started getting indexed, because the app was authenticating an anonymous user before it could render anything and nobody had traced it back that far. I owned character creation there end to end from nothing but mocks, so the flow, the edge cases and the architecture were all mine, along with the moderation and reporting side, public/unlisted/private visibility, and a staged rollout behind feature flags. Before that I led a three-person front-end team at SAIZ in Berlin, rebuilding a size recommendation widget so every brand could ship its own version, their fonts, their component choices, how many steps it had, where it sat on the page, all from one config file and dropped in with a single HTML selector. It runs on s.Oliver, Marc O'Polo and Jack Wolfskin. I taught myself Three.js and Blender for the 3D body avatars in it, and later tracked down the memory leak that was pushing browsers past 2GB. And for almost four years I was full-stack on Jebbit, now BlueConic, across three codebases in EmberJS, Ruby on Rails, Node and Postgres. L'Oreal, AutoZone and the NFL ran campaigns on it, peaking near a million sessions an hour in NFL season. I helped lead a four month refactor of the styling system, backwards compatible the whole way with both systems running in parallel, so nothing on the roadmap slowed down while we did it. On AI, I don't hand-write much code anymore. I spec the work, drive Claude Code and Cursor against it, and spend my day on judgment and review. The part that actually matters is knowing when to throw the output away. An agent reaches for whatever pattern is most common in its training data, and on anything holding real state that tends to be the version that reads fine in review and starts biting you a few months in. So I read the output rather than the diff, and I QA on real conditions before I call anything done. Less clever, doesn't break. I'm a product developer at heart. It's a product in the end, and it all resolves towards that. Send me the product and a sentence about what is going wrong with it. I'll come back with what I would look at first.
