What I Build

Full-Stack. Mobile.
Backend. AI.

End-to-end development across web, mobile, server, and AI platforms.

Web

Full-Stack Web Development

I architect and build complete web applications - from APIs and databases to beautiful, performant frontends. Whether you need a real-time SaaS platform, an API integration, or a full product rebuild, I deliver clean, maintainable code that scales.

Mobile

Mobile App Development

I build native-quality mobile applications for iOS and Android. From initial architecture and UI implementation to App Store and Google Play submission - I handle the full mobile lifecycle. Getting apps approved on the first attempt, not the fifth.

Backend

Backend Development

Scalable server-side systems built for production load: REST and GraphQL APIs, microservices, real-time communication, message queues, and cloud infrastructure. I design backends that hold up under pressure and grow with your product.

AI

AI & LLM Integration

Integrating AI into your product the right way: LLM-powered features, RAG pipelines, vector search, custom agents, and AI-assisted workflows. I bridge the gap between cutting-edge AI capabilities and real, production-grade product needs.

Why Work With Me

Not Just Another
Developer

After 10+ years and dozens of shipped products, here's what sets my work apart.

Product-Focused Mindset

I don't just close tickets - I think about the product holistically. Instead of completing Jira stories, I contribute to product vision and help design requirements that lead to stable, successful applications.

10+ Years of Real Experience

A decade of scars, solutions, and shipped products. I've seen what breaks at scale - premature optimization, wrong stack choices, tech debt - and I know how to prevent it before it becomes your problem.

Concept to Production

Give me a napkin sketch, a Figma file, or a half-formed idea. I'll turn it into a production-ready application - handling design, backend, frontend, integrations, and deployment end-to-end.

Startup Pitfall Awareness

I've worked with early-stage startups long enough to know all the traps. I help you avoid the wrong architecture decisions, over-engineering, and technical debt that kills momentum at exactly the wrong time.

Clean Code & Elegant Design

My rule: build something I can be proud of. Clean code. Elegant design. Good structure and modularity. I write code that your future self - and your future team - will thank you for.

Direct & Proactive Communication

No disappearing acts. I communicate proactively, surface blockers early, and keep you in the loop. I'm most effective when I have significant ownership and systems-thinking is crucial.

How We Work

From Idea to
Production

A straightforward process designed to move fast without breaking things.

01

Discovery

We align on goals, define the right tech stack, set a realistic timeline, and scope the budget. No surprises later.

02

Design

Wireframes, architecture diagrams, and API design. We agree on the blueprint before writing a single line of code.

03

Build

Sprint-based development with regular demos and code reviews. You see real progress every week, not just at the end.

04

Deploy & Support

CI/CD pipeline setup, server launch, App Store / Play Store submission, monitoring, and post-launch support.
