Backed by 8+ years of hands-on experience, I focus on delivering reliable, maintainable solutions that solve real business needs. I don't just build features - I help clients make the right technical decisions, reduce technical debt, and create software that remains easy to maintain as their business grows. I build robust, production-ready web and mobile applications designed to scale. No "vibe-coding" or quick AI-generated hacks here - I deliver clean, well-architected, and fully tested code that long-term projects actually require. I leverage modern AI tools such as Claude Code and OpenAI to accelerate development and eliminate repetitive work, but engineering decisions, architecture, code quality, testing, and every production release are always my responsibility. I believe AI is a productivity tool - not a replacement for software engineering. Every AI-assisted implementation is carefully reviewed, refactored, and validated to ensure clean, maintainable, and production-ready code. --------------------------------------------------------------- Here you can take a look on high quality code that are delivering for our clients (there are around 200 PRs that you can reference!

That's the standard I bring to every project.
