What I Build
Mobile App Development
Cross-platform iOS & Android apps built with Flutter. State management, API integration, payment gateways — fully production-ready.
Web Application Development
Full-stack web apps using React + TypeScript with Supabase or Node.js backends. Auth, real-time data, Stripe payments, Vercel deployment.
CRM & SaaS Platforms
Custom business tools — dashboards, booking systems, subscription platforms — built to your workflow, not off-the-shelf templates.
Landing Pages & Websites
Conversion-focused landing pages and marketing sites. Fast, mobile-responsive, and designed to turn visitors into leads.
About
Who I Help
I work with startups and small businesses that need a reliable developer to take their product from idea to launch. Whether you need a mobile app, a web platform, or a CRM — I own the project end-to-end so you don't have to manage multiple people.
I specialize in Flutter for cross-platform mobile apps and React + TypeScript for web. I've shipped real products for clients in the US and Europe — including a CRM with Stripe payments and conversion-focused landing pages for a logistics startup and a Norwegian agency.
You describe what you need, I scope it, we align on timeline, and I deliver. I communicate clearly, ship clean code, and don't disappear mid-project. Most MVPs I deliver in 3–5 weeks.
