Mateusz Rakowski — Senior Quality Engineering Specialist

Senior Quality Engineering Specialist based in Warsaw. Working in software quality since 2013 across fintech, compliance, and enterprise platforms. Agile Coach and Scrum Master. Before QA — four years in web design and UI/UX, which turned out to be more than useful.

I work at the intersection of test engineering, AI orchestration, and delivery strategy. My focus is building the processes, pipelines and tooling that make quality a natural outcome of how a team works — not an afterthought. Not a methodology purist — I care about whether the thing works and whether the team can sustain it.

Currently designing and building agentic AI workflows alongside hands-on QA work — from multi-stage orchestration pipelines to LLM-driven test generation tools. Everything here started as a real problem worth solving.

Currently: Senior QA Specialist at Dun & Bradstreet — financial data and compliance platforms, web and enterprise API layers.

Tools: Playwright · Postman · Newman · Python · JavaScript · PostgreSQL · MongoDB · Claude API · ChatGPT · GitHub Copilot · OpenAI Codex

Open to senior QA, quality engineering, and test architecture roles — particularly fintech, compliance, or technically complex environments.

QuACS — Quality Assurance Case Studies

Pronounced “quacks.” The duck is intentional.

A place to write about quality engineering the way it actually works. Real projects, real constraints, real outcomes. Details anonymised where necessary — problems, approaches and opinions are genuine, owned by me, edited by my friend Claude (Sonnet 4.6).

Case studies and projects

Quality Assurance — test strategy, automation, data validation, and what coverage metrics actually tell you.

Processes and Procedures — agile adoption, retrospectives, and how teams work versus how they think they work.

AI in Practice — using AI tools as genuine engineering instruments. Pipeline design, MVP builds, workflow automation.

AI Digest — filtered news across QA, agentic coding, and AI automation. Agentically automated.

I build tools and solutions to solve real problems — and document the process here. The blog pipeline itself is also a case study. That article is coming.
