I help startups and product teams ship production-ready web and mobile apps — on time, well-architected, and easy to hand off. Over 10 years I've gone from writing the first line of code to leading full engineering teams, including a SaaS platform on AWS that held 99.9% uptime under heavy traffic. Recent clients call me "committed to quality," "reliable," and someone who "does not fail the deadline." That's the baseline I hold myself to on every project. What I'm best at: ✔ React / Next.js frontends that are fast and maintainable ✔ Node.js + TypeScript backends and REST/GraphQL APIs ✔ React Native mobile apps (iOS & Android) ✔ AWS infrastructure — ECS, Fargate, Docker, CI/CD ✔ Real-time features: WebSockets, live dashboards, chat systems ✔ Fintech integrations: payment gateways, compliance, encryption ✔ PostgreSQL, MongoDB, Firebase I work with a small number of clients at a time so you get my full attention — not a response from a VA at 2am. If you have a project in mind, message me with a brief description and I'll tell you honestly if I'm the right fit.

When you hire a developer, you're not paying for code — you're paying for a working product. I make sure you get both. I'm a full-stack developer with deep expertise across backend systems, mobile apps, web development, and bot/automation engineering. Whether you need a high-performance API built in Go, a cross-platform mobile app, a polished web interface, or a Telegram/Discord bot that automates your workflow. I've built it, shipped it, and maintained it in production. What I bring to every project: • Clean, maintainable architecture (not just code that works today) • Clear communication and honest timelines (no surprises!) • A bias toward simplicity: the right tool for the job, not the trendiest one • Delivery that doesn't need a second round of fixes Tech I work with regularly: Go, Laravel, React, Flutter, Node.js, PostgreSQL, MySQL, AWS, Docker, and more. If you have a well-defined project and need someone who can own it end-to-end, let's talk.
