The Trailhead

Welcome, Traveler

I'm Liam — a software engineer from the West Coast who started out designing circuits and ended up building distributed systems. I love the craft of making things: clean code, elegant architecture, systems that hold up under pressure.

This is my corner of the woods. A place to share the projects I've built, the things I've been learning, and the ideas I want to pass on. I care a lot about helping people grow. Whether that's through mentoring, writing, or just building things worth studying.

Projects

Each project is a path I've explored — some winding, some steep, all worth the journey.

Rules Engine

Evaluates complex user-defined schemas and rules

Designed a stateless, horizontally scalable rule engine evaluating dynamic user-defined schemas via Common Expression Language
Achieved ~7k RPS per instance under sustained load (10-minute test, ~4M evaluations)
Identified and analyzed saturation behavior at tail latencies (p95 ~2.8s under peak load)

GoPostgreSQL

Distrace

Distributed tracing backend for OpenTelemetry

Correlates out-of-order spans across services using TraceID grouping and parent–child resolution
Implements bounded trace completion with inactivity and max-age limits (30s / 5m) to balance completeness with memory constraints
