SERGEI RUDIK · QA ENGINEER
I help you build a testing process, automate your API, and introduce AI assistants where they actually save the team time.
For teams with a working product and a growing backend.
Experience in product teams
01 / HOW I CAN HELP
From a focused review to full adoption.
Scope, result, and price are agreed before we start.
Bugs reach users, and the team cannot tell which checks matter most.
A risk map and a concrete action plan for the team.
Your backend keeps growing, manual checks take more and more time, and releases cannot wait.
A working set of automated tests your team can grow.
Checks take too long, random failures pull focus, and a red pipeline has become normal.
Fixes plus a before-and-after comparison of speed and stability.
Requirements, documentation, and failure triage eat time the team would rather get back.
A working pilot, a quality assessment, and a decision on further adoption.
02 / AI IN THE WORKFLOW
We start with a single task and measure the value on your own examples. You will see what the agent does and how its results are verified.
Pick a task for the pilotA new direction: we start with a limited pilot and quality criteria agreed up front.
Identify contradictions and prepare draft test plans, checklists, and test scenarios.
Draft tests from your API specification and project code, reviewed by your team.
Summaries from logs, grouped errors, and hypotheses about the causes of failures.
Data checks against rules and schemas; example sets for evaluating AI features.
Strict checks live in code. AI results are measured against quality criteria. Changes go through review.
03 / EXPERIENCE BEHIND THE OFFER
I have worked in QA since 2017. Currently on the SIEM team at BI.ZONE. I have automated testing for APIs, web applications, and mobile apps, built test infrastructure, and trained QA engineers.

Results from my own work experience. We’ll define your project goals after reviewing your needs.
04 / HOW WE WORK
I work personally: from the first review
to handing the result over to your team.
You tell me about the product, the problem, and the constraints. I clarify where I can help.
We agree on the scope, access, deadlines, price, and acceptance criteria.
I show intermediate results, discuss changes, and gather feedback.
I hand over the code, documentation, and recommendations. The team knows what to do next.
EXAMPLE FROM MY WORK
At BI.ZONE, I developed an automated testing strategy and a Python/pytest framework. I integrated tests into GitLab CI/CD.
API test coverage exceeded 60%, and regression testing time fell by 40%.
An example from my full-time role, without internal product details.
05 / BEFORE WE START
The price depends on the scope, the state of the project, and the access we get. After an initial review I propose a scope and an estimate. For an audit or a pilot we can fix a limited scope.
Yes. For example, triaging failing tests, automating one group of API scenarios, or an AI pilot that prepares checklists.
Yes. I can take on a specific part: the architecture of your automated tests, regression speed, CI, or introducing an AI assistant. The result is handed over to your team.
Before the pilot we agree on the allowed data, the model, and the environment. We choose what may go to external services and what must stay inside your infrastructure.
Yes, we discuss the format separately: evolving the tests, consultations for the team, or regular help with releases.
06 / START WITH YOUR TASK
Tell me about the product and the problem. I will suggest the next step and clarify what is needed for an estimate.
