I build production-ready Flutter apps and AI-enabled products for founders, startups and teams that need someone who can take ownership from idea to shipped software. My strongest lane is Flutter across iOS, Android, web and desktop, usually with Firebase or Supabase behind it. I also build React/TypeScript web apps, Firebase Cloud Functions, dashboards, internal tools and AI workflows when that is the fastest path to a working product. What I can help with: • Flutter mobile apps for iOS and Android • Flutter web/desktop apps and portals • MVP architecture, rebuilds and rescue projects • Firebase, Firestore, Cloud Functions and Supabase backends • API integrations, app maintenance, refactors and release fixes • AI features, agent workflows and automation around real business processes • UI/UX, product flow, technical planning and project management Relevant work: • Float Note — built an ADHD-focused task-management SaaS across mobile, web and desktop with Supabase. • MedApp — worked as Flutter lead developer, mentoring a team of up to about 10 people and improving delivery, reviews and technical process. • Friday Energy — redesigned and refactored the Flutter mobile app, including UI upgrades, caching, API migration, force update logic, feedback flows and language switching. • Go Potty — built a Flutter web portal with dashboards and insights, and improved the existing Flutter mobile app. • Roomy — built a Flutter MVP across web, Android and iOS, plus the Astro website, waiting lists and launch funnels. • SuperMarty — built a food/nutrition platform with React, Firebase, Flutter, AI workflows, scraping/search pipelines, meal planning and price comparison. • MIA — built a local-first invoice automation app with React, TypeScript, DuckDB, PDF generation and AI-assisted import mapping. Clients usually benefit most from me when the work is not just “write code”, but also needs product thinking, clear communication, technical decisions and steady execution. If the product is still messy, I can help turn it into a buildable plan and then ship it.

I help businesses and creators build mobile apps and web platforms using Android (Kotlin/Jetpack Compose) and React.
