About Me

Computer Science student, software engineer, and distributed systems enthusiast.

ENGINEERING PHILOSOPHY

Deterministic systems, resilient architectures, and quiet reliability.

I focus on engineering reliable backend services and clean data access layers. My approach prioritizes predictable system state, efficient query access paths, and strict schema contracts over superficial complexity.

Rather than relying on ungrounded abstractions, I believe systems are best designed by understanding the runtime and data layer realities beneath them—connection lifecycle, caching strategies, and defensive failure modes.
