Backend that holds up under load. AI that actually does something useful.
I design and deploy systems - from microservices in Java and PHP, through AI integrations, to process automation. I favor solutions that pass load tests before they pass code review.

Here's what a single request's journey looks like through the systems I build
This isn't a skills list - it's the real request path in Ordered, my distributed e-commerce system.
- Clientbrowser / mobile app
- API Gatewayrouting, JWT auth
- MicroserviceSpring Boot or Symfony
- Data & queuesPostgreSQL, Kafka, Redis
- ObservabilityGrafana, Jaeger, Prometheus
Services
Four areas I work in most often - each one comes from a project I actually built, not a list of trendy technologies.
- GET/backendBackend & distributed systemsI design and build backends - from a single API to a system made of several independent services.
- POST/ai-integrationAI integrationsI wire language models into real applications and processes - not to impress on a demo, but to solve a concrete problem: speed up a process, support a decision, generate a useful suggestion.
- PUT/automationProcess automation (n8n)I connect tools that today work in isolation - CRM, spreadsheets, inboxes, forms - into a single flow, so someone at your company stops manually copying data from one place to another.
- DEPLOY/mobileMobile apps (Flutter)I build mobile apps in Flutter - a single codebase for Android, iOS and web.
How I work
No surprises along the way - you know what stage the project is at and what happens next.
Experience
PHP Developer, Iteo S.A. (Toruń)
Built and maintained backend services in PHP and Symfony - new features, legacy code refactoring, REST APIs and database integrations (Doctrine ORM, PostgreSQL, MySQL). Wrote unit and functional tests (PHPUnit, Behat, PHPSpec), kept code quality in check (PHPStan, Psalm, PHP CS Fixer), and took part in code review and deployments alongside a team of developers, QA and product managers.
MSc in Computer Science (AI)
Nicolaus Copernicus University in Toruń, Artificial Intelligence specialization.
BEng in Computer Science
Nicolaus Copernicus University in Toruń. 3rd place in a university team programming project - as team lead, I coordinated the work and delivered the winning solution, which earned a cash prize.

I write about the projects above in more detail - what went wrong, what I learned. The posts are currently in Polish only.
