Senior🎓
Top SchoolKrzysztof Bezrąk is a seasoned software leader and entrepreneur with 11 years of experience building high-performance web and mobile systems and over eight years focused on full-stack engineering and architecture. As Co-Owner & CTO at Derave Software and founder of PlaidInvoices and Xoler, he blends product-minded leadership with hands-on delivery—designing B2B platforms, distributed mobile sales tools, franchise and quoting systems, and AI-powered customer support.

Comfortable across React, TypeScript, Go, cloud CI/CD and infrastructure tooling, he’s led migrations and shaped engineering practices while maintaining a bias for measurable outcomes. Based in Lublin, Poland, he pairs entrepreneurial grit with a knack for turning messy integrations into stable, low-resource solutions that scale.
