Performance-first Fixed-scope (1–3 weeks) or ongoing

Performance & Reliability

Identify bottlenecks, eliminate hotspots, and make the system predictable under load.

Lower latency, fewer incidents, and measurable improvements you can track over time.

When it fits

  • P95/P99 latency is climbing or unpredictable
  • You’re hitting scaling limits (CPU, DB, queues, GC, network)
  • Incidents repeat and root causes never get fully fixed
  • Cost is increasing faster than traffic

Deliverables

  • Profiling / load test plan + findings (what matters, what doesn’t)
  • Bottleneck fixes (query/index, caching, concurrency, payloads)
  • Reliability improvements (timeouts, retries, idempotency, backpressure)
  • KPIs + dashboards to keep gains from regressing

Not a fit for

  • Teams not willing to measure (no metrics, no baseline, no acceptance criteria)
  • Pure “lift-and-shift” efforts without addressing root causes

Contact

Tell me a bit about your context (stack, constraints, timeline) and what outcome you want.

Recommended info
  • Current architecture + biggest pain
  • Success metric (latency, cost, delivery speed, reliability…)
  • Constraints (team size, deadlines, infra, compliance)
