Hanz Fernando | Software Engineer

About

I'm a full-stack software engineer focused on building systems that turn live data into usable decisions. My work has included real-time telemetry dashboards, API platforms, public-facing Next.js applications, database workflows, caching, rate limiting, and production support for command center environments.

I like working across the full path of a feature: understanding the problem, shaping the data flow, building the interface, and making sure the system is reliable once people are using it. I care about clean UX, practical architecture, and software that is easy to maintain after it ships.
