I build end-to-end platforms with a focus on measurable impact—at HSBC, I led full-stack development for claims and Health Scan+, cutting processing time from 5 days to 5 minutes (99%) for 150K+ users in HK and Macau.

I’m hands-on across backend microservices and high-concurrency workflows: REST APIs, Hibernate/JPA, Redis caching, Kafka pipelines, and strict SLA compliance. On the frontend, I’ve integrated React Native (iOS/Android) and React.js with 30+ APIs, reducing average response time by 40%.

I also deliver growth and modernization through product scaling and automation. I scaled Video Consultation across React frontend, React Native mobile, and Java backend—onboarding new providers and increasing adoption by 25%—and built agentic AI tooling with LLMs to automate React Native → native migration, reducing effort from weeks to hours.

Security and reliability are core to how I work: I’ve owned full stack security (RASP, WAF, SAST, SonarQube, OWASP, Spring Security) and maintained zero high/critical vulnerabilities in production. Earlier, as a cloud engineer intern, I reduced AWS costs by 15% while maintaining 99.9% uptime using Auto Scaling, Lambda pipelines, and multi-AZ architecture.
