ABOUT ME

Lead full-stack JS developer with 9+ years of experience (previously at Thoughtworks)

I am a Lead Full Stack Engineer with over nine years of experience designing and delivering high-impact product across web, mobile, and backend platforms. I specialize in JavaScript, React, React Native, and Golang.

In my recent role as a Technical Lead Engineer at Thoughtworks, I led a cross-functional team to build a loan management system for a leading bank. This involved designing React web apps, mobile apps, and a Golang backend layer, all within a CI/CD ecosystem.

Beyond hands-on development, I’ve taken on leadership roles, mentoring developers, driving adoption of best practices, and delivering internal seminars on topics such as Web Application Security, Pipeline Optimization, and Test-Driven Development.

If you are seeking a highly skilled full-stack developer who combines technical expertise with leadership capabilities to deliver exceptional results, you and I would be a perfect fit.
