Adam Kadar is a Senior Full Stack Developer based in Budapest with 11 years of experience building scalable web and mobile applications using TypeScript/JavaScript stacks like React, Vue, NestJS, Express, Node and MongoDB. He has moved between startups and product teams—shipping real-time SPA editors, micro-frontends, payment integrations and last-mile delivery systems—while also handling API design, data migrations and client-facing architecture work. Comfortable across frontend and backend, he pairs rapid feature delivery with attention to robustness and maintainability, often owning both API and UI concerns. His background includes implementing auth systems (Amazon Cognito), building drag-and-drop template builders, and integrating CMS/CRM workflows for Danish enterprises. A quick learner and detail-oriented engineer, he frequently steps into client communication and project leadership on freelance engagements. He now contributes senior-level full stack expertise at Apex Lab, applying a pragmatic blend of startup agility and production-grade engineering.
