ABOUT — SCOPE & ETHICS

Project framing, data sources, what this is and is not.

Adaptable to your domain

Same QA discipline, different operational contexts

The tooling is the same: Playwright, K6, ZAP, Lighthouse. The vocabulary, failure modes, and risk surface adapt to your field.

Defense / Embedded

Mission-critical UIs and real-time telemetry. 291 E2E tests across 4 operational profiles (drone GCS).

Real-time UILatency SLAsE2E / multi-agent

Fintech / Trading

API contract testing, P95 latency, concurrent load. Failures cost money: zero flakiness tolerated.

API contractsLoad testingK6 VU ramp-up

HealthTech / MedTech

WCAG AA compliance, data integrity, regulatory traceability. Every test run documented and reproducible.

WCAG AAData integrityAudit trails

SaaS B2B

Auth, billing, permissions, multi-tenant isolation. The paths nobody tests until they break in prod.

Auth / RBACBilling testsMulti-tenant

E-commerce

Cart, checkout, payment, performance under peak load. Lighthouse CI gates to block regressions.

Checkout flowsPerf budgetsLighthouse CI

Industrial IoT

Sensor pipelines, protocol simulation, edge testing. From device event to dashboard assertion.

What you get

Three capabilities, one engagement

I cover the full QA spectrum: from zero-to-CI automation to security hardening and performance observability.

TEST AUTOMATION

→Playwright E2E: Chromium, WebKit, mobile Safari
→Multi-project CI/CD pipelines (GitHub Actions)
→Flaky-test diagnosis and systematic fix
→API contract testing: no browser, pure HTTP
→Test history, pass-rate trend, browser matrix

SECURITY & COMPLIANCE

→OWASP ZAP automated scans integrated in CI
→Content-Security-Policy design and audit
→HTTP security headers review (HSTS, X-Frame)
→OWASP Top 10 coverage mapping
→Remediation plan with severity triage

PERF & ACCESSIBILITY

→K6 load testing: configurable VU ramp-up
→P95 / RPS / fail-rate dashboards
→Lighthouse audits in CI (perf, a11y, SEO, BP)
→WCAG AA accessibility audit and remediation
→Budget gates: block deploys on regression

Typical missions

Scoped, priced, deliverable

Most engagements fit one of these four patterns. If yours doesn't, we'll scope it together.

Bootstrap QA from zero

No tests, no CI gate. I deliver the full stack: Playwright, GitHub Actions, pass-rate badge, and runbook.

2 – 4 weeks600 – 800€ / day

Fix flaky test suite + speed up CI

Flaky tests destroy trust. I audit, fix non-determinism, parallelize, and cut your CI time.

1 – 2 weeks600 – 800€ / day

Security audit + remediation plan

ZAP scan, CSP/headers review, OWASP Top 10 coverage. Prioritized report and remediation plan included.

1 weekFixed price: 4 500€

QA observability dashboard like mine

Live test results, Lighthouse, K6, ZAP, browser matrix. Deployed and CI-connected on day one.

2 – 3 weeksFixed price: 8 000 – 12 000€

How I work

Async-first, fully remote

Communication

→Async-first: no daily standups
→Written status update every working day
→Teams · Linear · GitHub · Email · LinkedIn

Logistics

→Timezone: France (UTC+1 / UTC+2 CEST)
→Languages: English · Français
→Fully remote: no onsite travel
→NDA available (mutual)

Honest about scope

What I am not

Knowing what a contractor won't do is as useful as knowing what they will. No surprises mid-engagement.

Not a full development team+

→I test software, I don't build features
→Greenfield full-stack project: wrong profile
→For "someone to handle everything": wrong profile

Not a body shop+

→I don't take a mission just for the budget
→Unclear scope or unrealistic timeline = I decline
→Short qualification form first: we both save time

Not on-site+

→Fully remote, no travel
→Day rate adjusted: lower overhead, same output
→Timezone: France (UTC+1 / UTC+2 CEST), async-first

Not equity, not deferred+

→Cash only: fixed price or day rate, invoiced on delivery
→No equity, no rev-share, no deferred pay
→Payment agreed upfront in the SOW

FAQ

Common questions

Why async?+

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.

Can you sign NDAs?+

Yes. A mutual NDA is available on request before any scoping call.

Do you take equity?+

No. Cash only. Fixed price or day rate.

Available for full-time?+

Not currently. Freelance missions only: this keeps me sharp across multiple stacks and gives you senior-level expertise without a full-time hire.

Do you travel onsite?+

No. Fully remote. This is reflected in the pricing.
