Karol Buczek

Web Systems Engineer • Full-Stack Developer • MarTech & Automation

I build internal tools that help marketing, product, and engineering actually work together.

I fix cross-functional problems — attribution gaps, tech debt, scattered data, and broken manual workflows and API integrations — using web tooling, cloud platforms, and practical AI to build reliable, measurable systems.

He's one of the rare professionals who can bridge the gap between deep technical capability and real business understanding. Whether the work involved internal tools, customer-facing platforms, or data connections between legacy systems, he always approached challenges with clarity, logic, and a calm, solutions-focused mindset.

What I Do

I like working on the unglamorous parts of the stack — the places where broken handoffs, bad data, or slow UX are quietly costing you money.
