What I'm looking for

I’m available for B2B contract work where I can own frontend engineering end-to-end—building scalable React/React Native interfaces, improving performance and developer experience, mentoring others, and shipping production-ready high-load UI.

I’m a Professional Frontend Engineer with 8 years of experience specializing in JavaScript-based technologies like React, React Native, and building scalable user interfaces. I’ve worked with both established companies and startups (local and international), which sharpened my pragmatic, business-oriented mindset and my ability to communicate easily across teams.

As a Senior Frontend Engineer at TN-Tech, I’ve led full-time work on long-term, high-load products—engineering core Ops web dashboards and a Driver mobile app, optimizing architecture for maintainability, reducing technical debt, and improving developer experience through new practices. I also contributed to Yahoo DSP stability and performance, including streamlining onboarding (1 month to 1 week), improving sprint velocity (~18%), mentoring 3 developers, and initiating a migration from Ember.js to React.
