I'm an AI Full-Stack Engineer building production-ready SaaS products, AI-powered applications, automation systems, and AI agents with Python, Node.js, Supabase, React/Next.js, and modern LLM technologies.
I work with startups, founders, and product teams that need more than a developer for isolated tasks. I help turn ideas, MVPs, and existing applications into reliable products that are easier to operate, scale, and improve.

Projekthistorie
▪ Led development of AI-augmented SaaS features and agent workflows for fintech, healthcare and logistics companies across 14 countries, using React, Node.js, Python, LangChain/LangGraph, and OpenAI/Anthropic APIs.
▪ Designed RAG pipelines with pgvector and Supabase Postgres, building tool-calling agents that automated document processing and customer support triage.
▪ Built React + Supabase SaaS frontends with Row-Level Security, Auth, and Edge Functions for multi-tenant access control and billing via Stripe.
▪ Set up n8n and cron-based automation to orchestrate multi-step agent workflows and webhook integrations for clients worldwide.
▪ Rescued and hardened AI-generated codebases — apps started in Cursor/Lovable — turning fragile prototypes into stable, production-ready products.
▪ Owned architecture decisions (ADRs), code review standards, and AI evaluation practices for a senior engineering pod.
▪ Developed multi-tenant SaaS platforms, internal dashboards, and AI-powered web apps for US- and European-based startups and SMEs, working 100% remotely in an international team.
▪ Built React/Next.js frontends and Node.js (NestJS) backends with TypeScript, focusing on authentication, billing (Stripe), and real-time data across distributed teams.
▪ Architected event-driven microservices and API integrations for clients in fintech, edtech and logistics, including senior Node.js and React feature delivery.
▪ Introduced LLM-powered features (automated tagging, document summarization) using Python services alongside the Node.js stack.
▪ Mentored two junior developers and led frontend architecture decisions for a multi-tenant analytics dashboard.
▪ Built and maintained full-stack SaaS web applications for clients around the globe — HRM, LMS and e-commerce platforms — using React on the frontend and Node.js + PostgreSQL on the backend.
▪ Designed REST APIs and integrated third-party services (payments, shipping, analytics) for international clients across Europe and North America.
▪ Implemented PostgreSQL data models, query optimization, and caching layers that reduced average API response times for high-traffic dashboards.
▪ Contributed to early AI-assisted features — smart categorization and helpdesk automation — getting first hands-on exposure to model serving and data pipelines.
▪ Worked in an Agile, remote-first team with code reviews and CI/CD, growing from junior to mid-level across 3 client engagements.
