Summary

Senior software engineer and technical delivery professional with 25 years of experience building, delivering, and scaling software systems, SaaS platforms, and data-intensive products. My background combines hands-on full-stack engineering, architecture, production delivery, and engineering leadership across focused product teams and organizations of up to 50+ engineers.

I have taken complex software and platform initiatives from ambiguous needs through technical scope, implementation, rollout, and reliable production operation. My experience spans full-stack product development, system design, data-processing systems, cloud-native delivery, and close collaboration with product, QA, DevOps, customers, business stakeholders, and technology partners.

My current focus centers on hands-on, AI-assisted product engineering. Recent work includes designing production RAG and agentic AI systems for Wrocław University of Economics and Business, architecting the GeoForm geospatial platform and its AI analysis agent, developing the Shape AI-delivery workflow, and joining the Toptal network as a vetted Senior Engineer.
