Jonas Keller

I'm a senior full-stack engineer with over a decade of hands-on experience building scalable, high-performing web applications from A to Z.

I specialize in modern frameworks like React.js and Next.js, and I'm equally comfortable on the backend with Node.js, PHP, and databases like MySQL, MongoDB, PostgreSQL(Supabase & Neon).

I've led end-to-end development pipelines, integrating CI/CD, deploying on AWS, and connecting automation tools like Make.com, Zapier, and n8n to streamline business operations. I'm also deeply experienced with AI integrations using the OpenAI API and Anthropic, helping teams level up productivity and user experience through intelligent automation and custom tools.
