Software developer from Poland
I build backend services, developer tools, frontend demos, and automation around delivery workflows.
- Java and Spring backend services, integrations, and performance experiments.
- TypeScript and React frontends, demos, and technical interview exercises.
- IntelliJ plugins and other developer workflow tooling.
- CI/CD, Docker, Jenkins, Argo CD, and infrastructure automation.
- 13+ years in software engineering, including long-running consulting and product delivery work at Jit Team since 2016.
- 8k+ authored commits across public demos, learning projects, and private repositories.
- Professional work across backend systems, frontend applications, platform engineering, cloud infrastructure, and delivery automation.
- Strongest recurring stack: Java/Spring, TypeScript/React, Kotlin, Docker, SQL, YAML, Terraform, Shell, and PowerShell.
- Comfortable moving between product code, integration work, build pipelines, infrastructure scripts, test automation, release management, and debugging production-facing systems.
- Experienced with legacy modernization, SVN-to-Git migrations, CI/CD automation, code reviews, technical guidance, and team leadership.
- Financial services and payments: backend platforms, integrations, reporting, and compliance-aware workflows.
- Retail, e-commerce, and logistics: operational systems, planning tools, POS-adjacent services, and data integrations.
- Travel and transportation: web applications, integrations, and business process support.
- Industrial, IoT, and building automation: configuration tools, service APIs, engineering workflows, and device-adjacent systems.
- HR, workforce, and internal operations: self-service portals, time/reporting tools, onboarding/offboarding, and process automation.
- Platform and DevOps work across sectors: cloud infrastructure, CI/CD, Kubernetes, observability, and deployment automation.
- Electronics and telecommunication engineering background from Gdansk University of Technology.
- Interests that often influence my side projects: cloud computing, virtual reality, embedded systems, and more.
