⠀⠀Strong Software Developer (Engineer) with a product-first mindset and a results-driven approach.
⠀⠀10+ years of experience launching projects from scratch, optimizing and refactoring legacy-code, building CI/CD processes, and organizing teams to deliver with predictable and consistent efficiency.
⠀⠀I believe in balancing quick, pragmatic solutions with long-term code quality and maintainability — depending on the product stage, business goals, and technical context.
⠀⠀I thrive on solving non-trivial challenges, breaking down complex problems into simple, effective solutions, and applying the 80 / 20 principle to stay focused on what truly drives business value.
