I build web platforms and Flutter apps, from interface to production.

I design the product, build the web and mobile interfaces, connect APIs and live data, develop the backend, add AI or payments where useful, and take the finished product through release.

What I can deliver

Full product ownership, including the integrations and operational work that sit behind the interface.

Product and web

Product structure, responsive interfaces, complex user flows and accessible design systems with React, Next.js, TypeScript, Vite and Tailwind.

Mobile applications

Flutter apps with native navigation, caching, deep links, media playback, push notifications, authentication and complete Google Play release management.

APIs and integrations

REST and JSON APIs, EuroLeague data, X data providers, YouTube, Reddit, Stripe, Supabase, Firebase, OAuth, webhooks and email services.

Data and statistics

Live game state, play-by-play, standings, team and player statistics, shot maps, normalization, versioned snapshots, caching and interactive charts.

AI and automation

LLM APIs, DeepSeek classification, structured outputs, source ingestion, scheduled pipelines, background workers and review-controlled publishing.

Backend, payments and operations

PostgreSQL, row-level security, realtime state, migrations, Stripe subscriptions, payment webhooks, Docker, Netlify, systemd, CI, testing and production recovery.

How I work

I use AI coding tools to move faster through research, implementation and testing. The output is still reviewed, tested, built and exercised in real product flows before it is treated as finished.

I am most useful when I can understand the product, build the interface and backend, connect the required services, ship the release and keep improving it from real feedback.

Have a product to build?

I am available for remote product engineering roles and contract work.
