Ken Chen
@kenchen
Senior full‑stack engineer focused on building scalable, data‑driven web platforms.
What I'm looking for
I am a senior full‑stack engineer with deep experience delivering reliable, scalable web platforms that combine clean frontend experiences with robust backend systems. I turn complex ideas into maintainable code and collaborate closely with design and product teams to ship impactful features.
At Enterpret I designed and optimized data pipelines, implemented real‑time alerting, built AI/ML integration layers for feedback classification, and improved backend performance with Redis caching and query tuning. Previously, I led development of a real‑time product editor, optimized site performance with code‑splitting and lazy loading, and introduced logging and monitoring to surface production issues faster.
I mentor developers, improve code review practices, and prioritize secure multi‑tenant architectures and role‑based access controls. I seek to continue building data‑driven products where performance, reliability, and strong cross‑functional collaboration matter.
