Profile
Software engineer with 20+ years of experience designing and building scalable cloud-native systems and modern web applications. Specialized in TypeScript, AWS serverless, enterprise integrations and event-driven architecture. Equally comfortable delivering pixel-perfect interfaces, full-stack products, backend platforms and automated CI/CD pipelines. Experienced in solution design, technical leadership, mentoring engineers and raising engineering standards through pragmatic, hands-on guidance. Recently focused on custom agentic systems, AI-enabled development and self-hosted open-weight LLM infrastructure, applying AI where it creates measurable engineering value rather than hype.

How I work

I don't tolerate half-finished work and always prioritize planning and considering all possible outcomes. Stress and pressure are not in my vocabulary — I prioritize quality over quantity. I effortlessly switch between tasks while maintaining a calm demeanor, continuously seeking to learn and grow. With a positive attitude and an open mind, I bring a "we can do it" mentality to every team I join.
Pixel-perfect philosophy
Making useful and beautiful apps is not just coding — it's the experience and feeling it portrays. I wear multiple disciplinary hats and get involved in the whole process: full-stack development + UX + CI/CD. The UX/DX is just as important as the tech behind it. A considered weakness? I am pixel-perfect. I consider CSS/SCSS equally important as any other language; you should know how to style.
