Patryk Kowalski is a TypeScript-focused full-stack developer with 8+ years of experience building high-performance, scalable web applications and PWAs from Warsaw. He specializes in modern Next.js frontends and NestJS backends, delivering self-service and e-commerce solutions that prioritize SEO, availability, and large-data rendering performance. As a founder of PK Code Design and a senior engineer at Mad Mountain and RTB House, he blends hands-on coding with mentoring, stack integration, and product-oriented thinking. His background spans frontend craftsmanship (Styled Components, Jest, Cypress) to backend concerns (MySQL, Redis) and includes confidential government projects and advanced Service Worker usage. Known for punctuality and an almost playful perfectionism, he treats continuous learning as a hobby, not an obligation.
