Junior IT candidate based in Poznań, Poland, interested in Application Support, QA, ERP, Backend, DevOps, AI/ML, and Game Development.
I build portfolio projects that turn practical workflows into verifiable software: testable QA case studies, contract-testing tools, typed React applications, CI pipelines, and Unity gameplay prototypes. I focus on clear scope, reproducible setup, documented limitations, and evidence that a reviewer can inspect.
| Area | Tools and technologies used in my public projects |
|---|---|
| Languages | TypeScript, C# |

| DevOps and delivery | Git, GitHub Actions, GitHub Pages, CI checks |
| Game development | Unity 6, Unity Input System, deterministic state machines, EditMode tests |
| Project | Focus | Evidence |
|---|---|---|
| QA Case Study Lab | Manual and risk-based QA, defect analysis, explainable release decisions, Playwright | Live demo |
| API Contract Testing Lab | OpenAPI, positive/negative contract checks, mutation proof, CLI reporting | Source and runbook |
| AI Job Application Tracker | Next.js product workflow, validation, local persistence, AI provider/fallback integration | Source and screenshot |
| Bug Bash Arena | Interactive QA game, severity decisions, accessible React UI, deterministic scoring | Play the game |
| Ashen Vale — Agentic Game Studio | Unity/C# gameplay systems, editor-built scenes, tests, documented AI assistance | Current development status |
- Designing test cases and defects around risk, expected behavior, and release impact.
- Building typed interfaces and domain logic with automated verification.
- Handling invalid input, corrupted local data, external-provider failure, and deterministic fallback states.
- Connecting local checks to GitHub Actions and deployed static demos.
- Documenting architecture, setup, engineering decisions, limitations, and next steps without presenting planned work as finished.
- Application Support troubleshooting, incident communication, and operational documentation.
- API testing depth: schema automation, HTTP adapters, authentication, idempotency, and CI evidence.
- Backend and ERP foundations: data modeling, integrations, business processes, SQL, and reliable import/export.
- DevOps fundamentals: deployment pipelines, observability, environment management, and secure configuration.
- Unity vertical-slice integration: gameplay state, quest flow, build verification, playtesting, and presentation.
The best public contact point currently available is my GitHub profile.
I do not claim commercial IT experience in these repositories. They are portfolio projects built to show practical learning, engineering discipline, and honest technical communication.
