I help startups and businesses turn ideas into scalable digital products, from MVPs to full SaaS platforms and AI-powered applications.

With over 10 years of hands-on development experience, I specialize in building fast, reliable, and scalable web and mobile applications using modern technologies. My focus is not just writing code, but delivering complete, production-ready systems that solve real business problems and scale with growth.

I have worked across SaaS platforms, AI-powered systems, and mobile applications, helping founders move from idea → MVP → scalable product.

💡 What I Build

✔ SaaS Platforms (multi-tenant systems, subscriptions, dashboards, analytics)
✔ AI-Powered Applications (LLM integrations, automation, intelligent workflows)
✔ Mobile Apps (iOS & Android using React Native / Flutter)
✔ MVP Development (rapid prototypes with scalable architecture)
✔ Full-Stack Web Applications (high-performance, modern systems)
✔ API Development & Third-Party Integrations
✔ Performance Optimization & Legacy System Improvements

🧠 My Approach

✔ Product-first mindset — I focus on solving business problems, not just building features
✔ Scalable architecture from day one
✔ Clean, maintainable, production-grade code
✔ Fast execution with attention to detail
✔ Clear communication and reliable delivery
✔ Clear, structured weekly updates — you never have to chase me for progress
✔ I validate requirements early and proactively push back on unclear or risky specifications before development starts ✔ Async-first workflow with strong communication overlap — I align with US/EU time zones with 3–4 hours of daily real-time availability for collaboration.
