I build production-grade cross-platform mobile apps and scalable web platforms — from MVP to enterprise. Clients hire me when they need someone who can own a feature end-to-end: mobile, backend, database, tests, and deployment. Mobile (iOS + Android): React Native, Expo, Ionic — full app store deployment, push notifications, offline-first, native modules. Frontend: Angular, React, TypeScript, Apollo Client, responsive UIs, component architecture that scales. Backend & APIs: Node.js, Supabase, Hasura, PostgreSQL, GraphQL, REST — real-time APIs, row-level security, auth flows, SQL performance tuning. Testing & Quality: Playwright (E2E), integration + unit tests, CI pipelines. I don’t ship code I can’t trust. DevOps: Docker, AWS, self-hosted VPS, TLS/certificates, CI/CD. Also experienced with: Java, Spring Boot, MySQL. I’ve worked inside large enterprise codebases where every change ripples through dozens of modules, and I’m equally comfortable greenfielding a product from zero. I understand what it takes to run a product, not just close tickets. Clear communication. Realistic estimates. Code you can hand to the next developer without shame. Available for long-term contracts or scoped projects. Tell me what you’re building.

🏆 𝗧𝗢𝗣 𝗥𝗔𝗧𝗘𝗗 𝗣𝗟𝗨𝗦 𝗨𝗽𝘄𝗼𝗿𝗸 𝗙𝗿𝗲𝗲𝗹𝗮𝗻𝗰𝗲𝗿 ✅ 𝟭𝟬+ 𝗬𝗲𝗮𝗿𝘀 𝗕𝘂𝗶𝗹𝗱𝗶𝗻𝗴 𝗪𝗲𝗯𝘀𝗶𝘁𝗲𝘀 𝗧𝗵𝗮𝘁 𝗖𝗼𝗻𝘃𝗲𝗿𝘁 🏅 𝗦𝗲𝗻𝗶𝗼𝗿 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿 + 𝗗𝗲𝘀𝗶𝗴𝗻𝗲𝗿 Most websites look fine and sell nothing. That's the problem I fix. I build websites for SaaS companies and growing startups that are clear, fast, and built to bring in leads. Not just pretty. Pretty is easy. Pretty that converts is the hard part, and that's where ten years of doing this actually shows up. Here's how I think about it. Your website isn't a brochure. It's the first conversation a stranger has with your business, and most of them leave in eight seconds because the site never told them what you do or why it matters. Usually that's a messaging problem wearing a design costume. I find it before I touch a single pixel. 𝗪𝗵𝘆 𝗽𝗲𝗼𝗽𝗹𝗲 𝗵𝗶𝗿𝗲 𝗺𝗲 I'm a senior developer and a designer, which is rarer than it sounds. You're not handing off between two people who blame each other when something breaks. The person who designs your site is the person who builds it, so it works the way it looks. I pick the right tool for your project instead of forcing every job through the same one. Some sites are best on a no-code platform you can edit yourself. Others need real engineering. I'll tell you which one you actually need, and why, before you spend money on the wrong thing. 𝗪𝗵𝗮𝘁 𝘆𝗼𝘂 𝗴𝗲𝘁 → A site built around what you're selling, not around a template. We start with your business and the problem it solves, then design backward from there. → Fast, responsive builds that hold up on every device, with the custom interactions, CMS, and e-commerce pieces your business needs and none of the ones it doesn't. → SEO and structure baked in from the start, so the site keeps earning traffic instead of needing a rescue six months later. → Something you can maintain. I don't build clever things that fall apart the moment I leave. The goal is a site that compounds, not one that needs me on retainer to stay alive. If your current site looks decent but isn't pulling its weight, that's usually fixable, and usually faster than a full rebuild. Send me a message and tell me what's not working. I'll tell you straight whether I can help.
