Software Engineer with 5+ years of professional experience and over 10 years of software development experience.
I specialize in building scalable, high-performance web applications using modern frontend technologies such as React, Angular, TypeScript, and Lit. Throughout my career, I have contributed to large-scale enterprise platforms serving millions of users in highly regulated and mission-critical environments.
My experience spans frontend architecture, micro-frontends, reusable design systems, performance optimization, cloud-based architectures, CI/CD pipelines, and modern software engineering practices.
I strongly believe that great software is not just about writing code—it's about delivering maintainable, scalable, and business-driven solutions while continuously improving engineering standards.

I approach software development with an ownership mindset.
I believe engineers should understand the entire lifecycle of a product—from architecture decisions and implementation to deployment, monitoring, and long-term maintainability.
AI tools can significantly accelerate development, but engineering judgment remains essential. I regularly use AI-assisted workflows to improve productivity while always validating, reviewing, and supervising generated solutions to ensure quality, security, and maintainability.
