7 years XP · 5 SaaS in production · Full QA observability stack live
The tooling is the same: Playwright, K6, ZAP, Lighthouse. The vocabulary, failure modes, and risk surface adapt to your field.
GCS interfaces, mission-critical UIs, real-time telemetry, latency SLAs. Built and tested a full drone command stack: 291 E2E tests across 4 operational profiles.
Order flow reliability, API contract testing, P95 latency budgets, concurrent VU load. Failures here cost money: no flakiness tolerated.
Data integrity, accessibility compliance (WCAG AA), regulatory-grade test traceability. Every test run is documented and reproducible.
Auth flows, billing edge cases, role-permission matrices, multi-tenant isolation. The complex paths nobody tests until they break in production.
Cart and checkout flows, payment gateway testing, performance budgets under peak load. Lighthouse gates in CI to block regressions before they ship.
Sensor data pipelines, protocol simulation, edge-device communication testing. End-to-end: from device event to dashboard assertion.
I cover the full QA spectrum: from zero-to-CI automation to security hardening and performance observability.
Most engagements fit one of these four patterns. If yours doesn't, we'll scope it together.
No tests, no CI quality gate, no idea where to start. I set up the full stack: Playwright suite, GitHub Actions workflow, pass-rate badge, and hand you the runbook.
Tests that fail randomly destroy engineering trust. I audit the suite, eliminate non-determinism, parallelize where possible, and cut your CI time.
OWASP ZAP scan, CSP and headers review, OWASP Top 10 coverage check. You receive a prioritized report and a step-by-step remediation plan.
A full engineering dashboard: live test results, Lighthouse audits, K6 load metrics, ZAP score, browser matrix. Deployed, CI-connected, ready on day one.
Knowing what a contractor won't do is as useful as knowing what they will. No surprises mid-engagement.
Fill in the form below: takes 3 minutes. I read every submission personally and reply within 24h.
Async communication produces clearer specs, better-documented decisions, and zero time wasted on status calls. You get a written update every day: more signal, less noise.
Yes. A mutual NDA is available on request before any scoping call.
No. Cash only. Fixed price or day rate.
Not currently. Freelance missions only: this keeps me sharp across multiple stacks and gives you senior-level expertise without a full-time hire.
No. Fully remote. This is reflected in the pricing.
