Performance Engineer. Strategic Optimizer. Systems Whisperer. I help engineering teams eliminate invisible bottlenecks—before they scale failure.
What I Do
I work at the intersection of performance engineering, systems strategy, and tooling. I've spent years helping organizations build faster, scale smarter, and measure what matters.
Core specialties:
- Performance testing & profiling (UI, API, DB layers)
- Tooling & frameworks that automate deep insight
- Debugging slow, misbehaving, or non-reproducible systems
- Training dev teams to think like performance architects
Signature Frameworks
- The 7 Silent Killers of System Performance
- The Teardown Stack
- Why Load Tests Lie (and How to Write One That Doesn’t)
Patterns I’ve seen in 30+ fire drills—and how to fix them early.
My exact process for triaging slow systems and surfacing root cause fast.
Most load tests are written to pass. Here’s how to write one that tells the uncomfortable truth instead.
Selected Work
- Dentrix Core Optimization
- Custom k6 Load Testing Framework
- gRPC Connection Stress Testing
Reduced load times by 45%, rebuilt test frameworks, uncovered regression patterns.
Dockerized plugin-ready k6 variant now used across org teams.
Simulated 20k concurrent connections, identified async stream thresholds.
