O mnie
Senior Full Stack Engineer and former Frontend Team Lead with nearly six years of experience building B2B SaaS, real-time trading, and high-traffic applications. My stack includes TypeScript, Node.js/NestJS, React/Next.js, PostgreSQL, Redis, and REST/GraphQL/gRPC. I own delivery from architecture to production.
I led development of a crypto trading interface serving 17,000–20,000 users on its first production day. Earlier work also included optimizing data-intensive processes, cutting 50-page scraping from 10–12 minutes to 2 minutes and database seeding from 5 minutes to 18 seconds.
Recently, for a restaurant SaaS platform, I built offline-first inventory workflows, worked on AI voice ordering, and developed wholesaler analytics: revenue and order forecasting, customer-specific pricing simulations, and analysis of product demand correlations. I combine hands-on engineering, technical leadership, mentoring, and a focus on measurable outcomes.
