Steve Leggett

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

Selected Work

  • Dentrix Core Optimization
  • Reduced load times by 45%, rebuilt test frameworks, uncovered regression patterns.

  • Custom k6 Load Testing Framework
  • Dockerized plugin-ready k6 variant now used across org teams.

  • gRPC Connection Stress Testing
  • Simulated 20k concurrent connections, identified async stream thresholds.
