At AtPulse, I work on end-to-end technical execution of healthcare platforms built from scratch. I run on site workshops with clinicians to translate clinical workflows into systems, then own backend architecture through to production. The platform is in daily clinical use by 200+ users at Asia's largest cardiac hospital, and I migrated the production database from Sydney to Singapore to colocate it with the app servers.

Product Engineer
At Progziel I led a team of engineers across mobile and backend projects, mentoring junior developers while staying hands-on with architecture and delivery. I introduced DevOps practices the team did not have before: Docker, CI/CD pipelines, Nginx. Built and shipped production-grade APIs and applications that were reliable and actually scaled. Worked closely with management on system design and feature planning, not just executing tickets. I took over a half built, bug ridden ERP and shipped it production ready in 1 month, and built Stripe Connect payments with webhook processing idempotent at the database level. Leadership recognised the work for consistently hitting critical deadlines without cutting corners on quality.
Emergen is where I got my hands dirty across the full stack for the first time in a real production environment. Started as a Flutter developer building cross-platform mobile apps for iOS and Android, then moved into full-stack work handling servers, databases, API integrations, and frontend all at once. Learned to write code that other people could actually work with, collaborated closely with designers, and shipped features that users relied on. That foundation of building end-to-end and caring about the whole system is what I carried into everything after.
