No templates. No shortcuts. Just clean, scalable, production-ready code delivered on time, every time.
What I Build:

- Full-stack apps with Node.js, Firebase, or Python backend
- Figma to Flutter/React Native

I've been building web and mobile products since 2020. In that time I've helped businesses modernize their platforms, launch SaaS products that manage internal teams and client communication, and ship things that actually make a difference.
I take on the full picture: web, mobile, APIs, real-time features, and I stay involved after delivery until everything works exactly as it should. Clean code, full documentation, and 3 months free maintenance come with every project.
Message me. I respond within the hour.

FAQ
How do I know my idea is safe with you?
Your idea is 100% confidential. I sign NDAs upon request and never share, reuse, or discuss any client project. Professionalism and trust are the foundation of everything I do.
What areas of development do you cover as a full-stack developer?
Frontend (Flutter/React Native), backend (Node.js, Python, Firebase), database design (MySQL, PostgreSQL, Firestore), API integration, and full deployment to App Store & Play Store.
Is it possible to develop Android and iOS versions of my app together?
Yes, that's exactly what Flutter and React Native are built for. One codebase, two platforms, delivered together. No extra cost, no extra time.
What if my mobile app idea isn’t fully fleshed out yet?
That's perfectly fine. We start with a free consultation call where I help you define the scope, features, and roadmap. Many of my best projects started as rough ideas.
Do you offer assistance after the app goes live?
Absolutely. I provide 3 months of free maintenance on projects $1,000+. I'm not a one-time vendor, I stay with you long term to make sure your app succeeds.
