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

I am a Lead Full Stack Engineer with over nine years of experience designing and delivering high-impact solutions across web, mobile, and backend platforms. I specialize in JavaScript, React, React Native, and Golang, utilizing these technologies to develop robust systems, including loan management platforms generating millions in revenue and microsites that expand client customer bases.

In my recent role as a Technical Lead Engineer at Thoughtworks, I led a cross-functional team to build a comprehensive 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. Additionally, I standardized development processes and refined system requirements to ensure alignment with business objectives.

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, I would be delighted to contribute to your project’s success.
