Message

At EmployPlan / Oberon Corporation, I designed and developed AI-powered tools to automate intellectual labor, including Kraken, built with Angular, .NET Core, and SQL Server. I led three development teams and managed a portfolio of connected apps forming an architecture that automates business operations.

At VicTree, I designed and developed a gaming NFT portfolio management app. The team built an MVP that reached 300 active users, with integrations to sync blockchain wallet assets and calculate their value over time.

At Fabrity, I designed software across fintech, Polish Railways, and medical billing projects, and assisted a British fintech with architecture restructuring. Earlier, I worked on e-learning systems, investment banking software, and banking platforms, including performance improvements that reduced calculation time by as much as 98% on three projects.
