Jedrzej Lewandowski is an engineering manager and front-end specialist with 15 years of professional experience and over eight years focused on building fully typed JavaScript applications and SDKs using TypeScript beyond typical React stacks. He’s led major rewrites and migrations (notably a checkout SDK that became the default merchant path and Angular-to-Next.js B2C migrations), improved performance and scalability, and established cross-team engineering standards and guilds to raise quality and developer growth. Comfortable across the full stack, he pairs front-end architecture with Node.js APIs and PostgreSQL/NoSQL design, and brings an academic grounding in C++ alongside a soon-complete BSc in Computer Science. At Primer he transitioned from senior frontend lead to managing backend teams and driving company-wide AI adoption to accelerate engineering workflows. Colleagues know him for balancing rapid delivery with deliberate technical discovery and for translating merchant needs into reliable, enterprise-grade integrations.
