Senior Backend Software Engineer

Terry Chong Zi Yi

I modernize legacy enterprise systems into microservices, define the architecture standards teams build on, and lead small engineering teams through delivery. Lately I've been embedding AI-assisted development into the SDLC as a first-class practice.

About

Solution-oriented backend engineer with a track record in legacy system modernization, microservices architecture, AI-assisted development workflows, and enterprise solution design. I bridge business needs and technical delivery — defining architecture standards, building the foundational frameworks a team reuses, and leading modernization and AI-agent-driven engineering initiatives.

I provide technical leadership by managing and mentoring engineering teams of 3–4 developers across major projects, keeping delivery scalable and high-quality within project timelines.
