Career Journey
A timeline of roles and responsibilities across my engineering career
Cloud Architect & Platform Engineer
Hitachi Energy
Owning multi-cloud architecture (Azure & GCP) for critical energy infrastructure. Designed and operating production Kubernetes clusters with full CKS/CKA/CKAD expertise — driving platform standardization, zero-trust security posture, and developer self-service across distributed engineering teams.
Azure Solutions Architect
Benefit Systems International
Defined cloud architecture strategy for international expansion. Designed highly available Azure infrastructure serving multiple markets, established IaC standards with Terraform, and reduced infrastructure provisioning time from weeks to hours through automated landing zone patterns.
Principal Cloud Engineer
Transition Technologies PSC
Technical lead for cloud transformation initiatives. Established organization-wide cloud-native patterns, led architecture reviews, and mentored senior engineers on distributed systems design and Azure best practices. Drove adoption of GitOps and containerized workloads.
Azure Architect & .NET Team Lead
Billennium
Led cross-functional engineering teams (Poland & Asia, 10+ engineers). Architected and delivered a government-scale tax filing platform (ASP.NET Core, Vue.js, Azure) handling millions of submissions with strict security and accessibility compliance. Owned technical roadmap, cost optimization, and client architecture decisions.
Software Developer
PGS Software
Delivered end-to-end features in cross-functional product teams. Owned software design from requirements through production deployment, with focus on code quality, testing practices, and performance optimization.
Software Engineer
Ailleron
Engineered mission-critical banking systems for top Polish financial institutions — authentication platforms, online deposit flows, and leasing portals processing real-time financial transactions. Reduced CI build times and introduced code review culture that became org-wide standard.
Software Developer
SolvSoft / International
Built full-stack .NET applications in Agile teams. Gained international experience through a technical scholarship at Huazhong University (China) and an Erasmus engineering internship (Cyprus) — developing early cross-cultural collaboration and systems thinking skills.
