Profile
Software engineer from Myanmar shipping healthcare and enterprise products. I focus on system design — how services split, how data moves, and how real product flows hold up in production.

- Product flows
- Service boundaries
- Reliable releases
Background
I'm Phyu Sin Khant Aung, a software engineer from Myanmar, now based in Phuket, Thailand, working remotely with a US-based team.
I started learning software development in 2021 and grew into a software engineer at MyanCare, working on healthcare and enterprise products, including telemedicine, hospital management systems, EMR, CRM, and backend services.
My strength is turning complex requirements into practical, reliable software. With experience across the stack, I focus on backend engineering, system design, and building services that work well together and scale as products grow.
I enjoy understanding problems deeply, simplifying system complexity, and building solutions that are maintainable, reliable, and useful in real-world production environments.
