About

Hi, I’m Anders Nielsen. I’m a Senior Full Stack Engineer based in Denmark with 8+ years of experience designing and delivering high-performance, scalable applications across e-commerce, healthcare, fintech, and immersive platforms. I specialize in Node.js, Next.js, GraphQL, and cloud-native microservices, and I thrive on solving hard technical problems with robust architecture and collaborative teamwork.

I’ve shipped CRM dashboards, client portals, and AI-integrated SaaS platforms, built scalable APIs and ETL pipelines, and led end-to-end performance optimizations using TDD, DDD, and observability tooling. I enjoy mentoring teammates and turning complex requirements into reliable software that users love.
