Our Mission

Bridging the Digital Gap with Confidence

At vaet, I believe that technology should empower businesses, not overwhelm them. My mission is to help traditional companies modernize through custom software development, rigorous quality assurance, and sovereign AI integration. From building your first web presence to deploying private AI on your own infrastructure — I combine hands-on expertise with a structured approach to deliver solutions you can trust and fully own.

Track record

Measured results, not promises

Three results from the founder's own QA work, each one published on his LinkedIn profile.

  • ~1,200

    Playwright tests in 325 spec files and about 52,000 lines of test and support code, on a multi-tenant vehicle-auction platform. In continuous use since 2023.

  • 7/10 → 0/10

    A flaky bid widget traced to a backend race: stale renders clustered at 73–234 ms, correct ones at 25–56 ms. After the backend fix, the stale rate fell from 7 in 10 to 0 in 10.

  • 12 days

    A k6 load-test harness reported a clean pass for twelve days while aborting on every run. Caught and fixed.
