Mateusz Kocioła

Core contributor on a four-person team that built an end-to-end automated GPU validation environment from scratch, supporting driver validation ahead of release.

• Owned all test automation — machine provisioning, test execution, and results/database handling (Ansible, Python) — reaching production use in under 6 months.
• Automated real-world user-scenario validation (driver benchmarks, games, desktop applications) across multiple GPU generations, replacing largely manual workflows.
• Implemented and automated GPU virtualization testing using SR-IOV.
• As the work grew to integrate more projects and a wider validation scope, kept building automation and new features across the team's tooling (Ansible, Python) — including multi-cluster test orchestration with Slurm — while co-owning all CI/CD.
• Driving the consolidation of separate tools into a single platform integrated with existing internal testing infrastructure; tooling relied on daily by multiple teams.

Sole owner of a fuzz-testing initiative for internal microservices — inherited from a stalled start and brought into production.

• Raised fuzz-testing coverage from ~5% to 70%+ across Node.js (and some C++) microservices.
• Built and optimized CI/CD pipelines to run fuzzing continuously, reusing already-fuzzed inputs to cut redundant runs.
• Automated code-coverage reporting.

Developer on an internal HPC (high-performance computing) testing environment, building automation and internal tooling while helping the team level up.

• Scaffolded three internal full-stack web apps to automate team workflows — ticket creation, test execution, and regression finding; two became durable, daily-use team tools.
• Trained teammates in web development so they could extend these tools independently.
• Tuned low-level, bare-metal performance settings (environment configuration, CPU/GPU pinning) to increase workload throughput.
• Automated synchronization with internal testing services (Python, GitHub Actions) and integrated open-source and in-house HPC applications.
• Maintained and extended the environment (Bash, Python) across multiple Linux distributions (RHEL, SLES, Ubuntu); handled debugging, issue isolation, and code review.

Run a one-person web studio building static websites for individuals and small businesses end to end — design, development, client management, and post-launch support.

• Design and build static sites with Astro, Tailwind, and Figma, consistently scoring 95+ on Google PageSpeed Insights.
• Deliberately ship static architecture so clients can't break their own sites — minimizing maintenance and support overhead.
• Own the full engagement from scoping to ongoing support; recently brought on a collaborator to take on more work.
