Senior Quality Engineer · SDET

Engineering confidence into every release.

I turn flaky, unknowable systems into signal. Unified web, API, mobile & performance suites that catch defects before your users do.

(01) Manifesto

Quality isn't a phase you bolt on at the end. It's an engineering discipline — built into the pipeline, measured in production, and owned like a product. I build the systems that let teams ship fast and sleep at night.

Spectra — Unified Test Framework

A single TypeScript monorepo that unifies web E2E, API, mobile and performance testing behind one runner, one report and one CI graph. pnpm + Turborepo, BDD-first, fully observable.

  • Playwright + BDD
  • Maestro
  • k6
  • Allure · Grafana
4→1test stacks consolidated
11 minfull suite, in parallel CI

Atlas

Atlas Checkout

Re-architected an end-to-end checkout suite around resilient page objects and contract tests. Escaped defects dropped sharply while the suite got faster.

  • Playwright
  • Visual diffing
  • Stripe sandbox
-73%escaped defects

Pulse Banking App

Maestro flows across iOS & Android replaced a manual regression ritual. Release sign-off went from a three-day slog to a coffee break.

  • iOS + Android
  • Device cloud

Vela API Platform

k6 load & soak scenarios wired into Grafana, with thresholds as merge gates. Performance regressions now fail the PR, not production.

(03) The Stack

Five layers.
One source of truth.

L1

Web E2E

Gherkin-driven Playwright with playwright-bdd. Page objects, fixtures, parallel sharding.

Playwrightplaywright-bddPage Objects
L2

API & Contracts

Same runner, no browser. Request context, schema & contract validation, data factories.

APIRequestContextFakerContracts
L3

Mobile

Maestro YAML flows across iOS & Android. One flow set, real selectors, emulator or cloud.

L4

Performance

k6 from smoke to soak. Thresholds as pass/fail gates, streamed live to dashboards.

L5

Observability

Unified Allure report for functional + JUnit, Grafana + InfluxDB for performance trends.

(04) How I work

Green builds
aren't luck.

  • Shift left, observe right. Catch it in the PR; confirm it in production telemetry.
  • Tests are products. Readable, deterministic, and maintained like the app they protect.
  • Flake is a bug. A test you can't trust is worse than no test at all.
  • Quality is everyone's. I build the rails; the whole team ships on them.
