Über mich
I'm a Full-Stack Engineer with 3 years of production experience in TypeScript, Node.js/NestJS, and React. I specialise in third-party API and AI/LLM integrations — connecting external services, payment/CRM/ad APIs, and AI providers (OpenAI, Claude, Gemini) into real applications.
I spent 3 years building an ad-tech SaaS product with 8+ API integrations, and recently shipped two open-source full-stack AI tools end-to-end. I focus on clean, reliable integration work that holds up in production.
