@kjelleilertseneilert

I build optimized web and mobile platforms with React, Next.js, and Node.js.

I've built and improved web platforms for Banco do Brasil, CVC, SAP, and real estate education products. At Saiborne, I lead React/Next.js frontend architecture, implement design systems, deploy adaptive LMS modules, and build Python/Django services and integrations.

Across six years in web development, I've delivered full-stack applications with React, Next.js, Node.js, Java, Python, and C#, while improving accessibility, performance, testing, and engineering workflows. I also bring UI/UX design experience, Web3 development experience, and a collaborative approach to multicultural teams.
