Manual testing is slowing your releases and costing you money. I help tech teams automate their quality assurance to ship bug-free code 70% faster.
As a Top-Rated QA Engineer (100% Success on Upwork), I build robust testing frameworks tailored to your stack.
What I deliver in this service:
End-to-End Automation: Web & Mobile testing using Python + Selenium/Pytest.
API Testing: Complete validation of your REST APIs (Postman/FastAPI).
CI/CD Integration: Automated test suites that run on every deploy.
Regression Testing: Ensuring new features never break your existing code.
Stop fixing bugs in production. Let’s automate your success.

🛡️ Testing Pyramid: Why E2E is Your Ultimate Guardrail
In Agile, speed is nothing without stability. While Unit tests are the foundation, End-to-End (E2E) tests are the "Proof of Life" for your product.
Unit tests verify the code. E2E tests verify the business.
The E2E Advantage:
User Reality: It’s the only layer that mimics the actual human journey from login to checkout.
The Final Shield: It catches the "impossible" bugs that slip through the cracks of isolated integration tests.
Stakeholder Trust: It provides the definitive "Green Light" for production-ready code.
I don’t just build scripts; I build verified user experiences. By focusing on high-impact E2E automation, I ensure every deployment is a win, not a "maybe."
Stop guessing if your app works. Know it does.

I developed an end-to-end automated video production pipeline that transforms raw text into high-fidelity video content. By bridging Google Drive, Claude, and HeyGen, I built a system that ingests Markdown files and programmatically generates structured narration scripts and AI-driven video avatars. This solution replicates the exact quality of a manual creative process while operating at 10x the speed, delivering final video drafts directly to YouTube for review.
Built 130+ engineering calculators spanning 13 disciplines — process, pipeline, mechanical, civil, electrical, instrumentation, safety, operations, rotating equipment, tanks, utility, piping, and general.
Originally deployed as an internal tool with a hosted dashboard for a midstream oil and gas operator. Now rebuilt as interactive web calculators in Catalyst OS, running client-side with React and TypeScript.
Each calculator features validated inputs with unit handling, real-time computation, results export, and responsive design. Includes financial tools (debt payoff, FIRE number), health tools (TDEE, sleep debt, burnout risk), and engineering tools (pipe flow, heat transfer).
Tech: React 19, TypeScript, Tailwind CSS. No backend calls — all math runs locally in the browser.
