Matej Lelek

Proficient in frontend, backend, mobile, and database architecture, complemented by CI/CD pipeline setup, cloud technologies, and game development.

Sculptured skills through turning personal projects into profitable ones, handling projects for personal clients, contributing to projects in vendor companies, and managing legacy applications while working in banking.

I prioritize quality products while easily adapting to new technologies, recognizing that each application demands specific tools rather than allegiance to any particular technology.
