What I'm looking for

I’m looking for a role where I can build resilient full-stack systems, improve performance through best practices, and own end-to-end delivery—turning legacy complexity into faster, more engaging user experiences.

I’m a full-stack developer with 10+ years of experience in JavaScript, specializing in React, Node.js, NestJS, and TypeScript. I bring an antifragile mindset, adapting quickly while fostering a high-performance culture grounded in best practices and optimization.

I’ve delivered measurable impact by revamping legacy systems—cutting load times by half and boosting user engagement by 30%. In recent work, I resolved critical bugs, implemented Sentry for real-time error tracking, and integrated Firebase services to improve app functionality and data management. I’ve also fixed AdMob-related issues to ensure smooth ad display and improved revenue stability.

Across roles, I’ve led UI overhauls to enhance onboarding and usability, improved stability with event tracking and payment/verification reliability, and built advanced features like in-app tutorials and split payment. I’ve designed microservices architectures to reduce request-response time, developed authentication and payment processing systems, and supported scalable growth. I continuously push for maintainability through structured workflows, CI/CD, and strong collaboration with marketing and customer support to drive targeted improvements.
