What I'm looking for

I’m looking for a team where I can modernize complex UI, reduce technical debt, and guide others through hands-on mentorship—balancing rigorous architecture with pragmatic delivery, collaborating closely with stakeholders to ship reliable, maintainable products.

I’m a Senior Front-End Specialist with over 10 years of experience and a unique background in Mathematical Logic. I bring a rigorous yet pragmatic approach to complex UI challenges, specializing in Vue and TypeScript while leveraging broad engineering depth.

In my current role, I modernize legacy search pages, architect complex UI feature delivery, and reduce technical debt to improve system reliability. I also champion best practices and provide hands-on technical mentorship to raise quality and team capabilities.

Previously, I led high-performance .NET front-end projects, orchestrated comprehensive UX redesigns, and partnered closely with clients and product owners to translate requirements into high-satisfaction solutions. I’m motivated by technical strategy, clean architecture, and collaborative discussion—while using AI tools (e.g., Copilot, LLMs) and automation to accelerate development without sacrificing rigor.
