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)

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
