SDET · QA Engineer · Software Developer

I build softwarethat works.And make sureit keeps working.

By day I'm a QA engineer and SDET, testing and automating web applications. On the side I build them. Each sharpens the other, so what I ship works and keeps working.

Building software with quality at its core.

I'm a QA Engineer and SDET who enjoys building software as much as I enjoy breaking it. At work, I focus on testing, automation, and helping teams ship reliable products. Outside work, I build web applications and explore ideas that make me a better developer. Working on both sides has taught me to think beyond whether something works, and focus on how well it works for the people using it.

Two tracks, one engineer.

The day job and the side projects are separate, and they keep improving each other.

01 · At work

QA Engineer & SDET

Testing and automating web applications so teams can release with confidence.

  • Better QA workflows and coverage
  • Playwright
  • Katalon
  • Postman
  • Azure DevOps

02 · On the side

Software Developer

Designing and building full-stack web applications from the database to the interface.

  • React and Next.js front ends
  • Node.js and Laravel back ends
  • APIs, databases, and deployment
  • Maintainable, readable code
  • React
  • Next.js
  • Node.js
  • .NET
  • Laravel
  • MySQL

Where they meet

  • I build with testing in mind

    Code is easier to trust when I've already thought about how it could fail.

  • I test with a developer's eye

    Knowing how software is built helps me find where it breaks and write sturdier automation.

  • The same standard in both

    Whether I write the feature or the test, I care that it still works next month.

Quality isn't a phase. It's part of how I build.

Quality engineering is more than finding bugs. It shapes how software is planned, built, and released.

Stage 1 of 7

Understand requirements

Clarify what the software should do, and for whom, before anything is built or tested.
