I am expert in data integration using Talend Data Integration, database administration and processing xml files (xpath, xslt, xquery). I am master in business intelligence and specialist in process software development My experience with Talend Open Studio, SSIS, SSAS, SSRS started in 2006

I fix slow or unstable systems — especially the ones others couldn’t — and make them scale properly. I’m Jan — a Fractional CTO with 25+ years of experience turning ideas into production-ready systems. I don’t just advise — I fix and build. I work with startups and growing companies where things are starting to break — or never worked quite right in the first place. Usually when something has already gone wrong — or needs to scale fast. ⚙️What I help with: - Acting as a Fractional CTO when senior direction is missing - Translating business needs into practical technical solutions - Designing scalable architecture and APIs - Fixing performance and stability issues - Optimizing Linux servers and infrastructure - Refactoring legacy PHP into clean, maintainable code 📍Typical situations I come into: - “Business and tech are not on the same page” - “Things get lost between requirements and implementation” - “We’re not sure what the real problem is” - “It works, but it’s slow or unstable” - “We’re scaling and things are breaking” - “The codebase is a mess and nobody wants to touch it” 🧠How I work? Simple solutions. Real performance. No overengineering. I go from architecture down to code, database, OS, and network — whatever it takes to make it work properly. 📩Most of my work is long-term and under NDA, but I’m happy to take a quick look and tell you honestly what’s going on — and how to fix it. 👉 If you’re not sure what’s wrong, I can usually identify it in one call.
