About
Release-risk support for SaaS teams that need stronger QA coverage
TestVector provides QA/SDET review, implementation, and handoff for SaaS teams that need fewer release surprises. The work focuses on how your product is built, checked, and shipped before adding the right checks around the gaps.
Credibility
Why TestVector fits this work
TestVector is led by Denis Tikhomirov and built on 6+ years of QA/SDET work across products where missed issues can create bad reports, wrong data, support escalations, and rushed fixes. The work covers product review, test planning, automation, database checks, file and report validation, CI, and release support.
TestVector focuses on systems where failures hide behind passing UI checks, existing database records, generated files, stale pipeline outputs, and CI runs that look green without proving the right behavior.

Engagement model
How the work usually runs
Review: learn how your product is built, checked, and shipped.
Findings: show what is covered, what is missed, and what should be fixed first.
Implementation: add or improve the checks that make sense for your product.
Handoff: leave documentation, examples, and a setup your team can maintain.
Accountability
How TestVector takes responsibility
TestVector does not stop at a list of observations. The work connects findings to fixes: the workflows to check, the layer where each check belongs, the automation or validation needed, and the handoff your team needs to keep the coverage useful.
- Clear scope before work starts
- Findings tied to implementation options
- Practical fixes, not only recommendations
- Documentation your team can keep using
- Follow-up support available when the release risk continues

Who TestVector works with
The strongest fit is a team that keeps getting surprised after release.
TestVector is most useful when test count is not the hard part. The hard part is knowing what the system supports, where failure would hurt, and which checks create false comfort.
- SaaS teams scaling faster than their QA maturity
- engineering teams with noisy CI and nervous releases
- teams relying on shallow UI-only automation
- companies with critical backend, data, reporting, or output workflows
- organizations where failures are expensive or difficult to detect
- teams that already have tests, but still do not trust releases
- startups moving from reactive QA to engineering-grade verification
