What I'm looking for

I am looking for a senior engineering role where I can modernize backend services, build polished front ends, lead technical delivery, and work in a collaborative, DevOps-driven culture focused on secure, high-quality releases.

I am a Senior Full Stack Developer with over 15 years of experience building secure RESTful APIs and complex stateful user interfaces for global financial institutions and large enterprises. I specialize in Java and Spring Boot on the backend while modernizing services with Kotlin and Python, and I build responsive front ends using React, TypeScript, and Angular.

I have delivered production-grade systems for clients such as RBC, DBS, UOB and McGraw-Hill, led small development teams, performed code reviews, and managed deployments across CI/CD pipelines on AWS and Azure. I emphasize engineering excellence—using test automation (Selenium, TestNG, JUnit), performance tuning, and AI-assisted tooling to optimize code and deliver reliable releases.

I seek to join teams that value secure, maintainable architecture and continuous delivery, where I can contribute backend expertise, front-end craft, and cloud/DevOps experience to modernize services and drive measurable business impact.
