About Me

Over the past 18+ years, my career has evolved from building client-focused websites and CMS platforms to engineering scalable APIs, analytics systems, and fintech applications. I have worked across startups and enterprise environments, contributing to high-performance platforms in financial services, data analytics, and e-commerce, with experience spanning Asia and North America.

Beyond coding, I value thoughtful architecture, clean system design, and collaboration. I work closely with product and business teams to translate requirements into reliable, user-centric solutions, while mentoring engineers and fostering a culture of technical ownership and continuous improvement.
