I help businesses turn ideas into reliable, scalable products by covering the entire development cycle — from making key technical decisions and defining development processes to hands-on coding and leading teams.

My core expertise is fullstack engineering with TypeScript (backend and frontend), with a proven track record of building production-ready solutions that directly support business growth. A major focus of my work now is Telegram Mini Apps (TMA) — I design and develop high-load, user-friendly products that fully leverage the Telegram ecosystem. I also have deep experience with Firebase, using its full suite of services to rapidly launch and scale products. I actively apply AI technologies both as part of my development process (optimizing workflows, code generation, testing) and in product features (AI assistants, smart automation), delivering solutions that make products smarter and more efficient. Additionally, I bring experience in blockchain integrations where needed, but my primary value is in delivering pragmatic, business-focused solutions with the right technology for the job. As a team leader and former CTO, I know how to manage engineering teams, allocate resources effectively, and build development processes that scale. I’m deeply involved in business and product decisions, ensuring that technology choices align with long-term goals and create measurable impact. In short, I connect business vision with technical execution — and make it work.
