Hi, I’m Alex Meduna, a full-stack engineer with 10+ years of experience building, operating, and scaling SaaS products in real-world production environments. I work across frontend (React, Next.js, TypeScript) and backend (Node.js, FastAPI, Java/Spring) and have strong cloud infrastructure experience on AWS. In recent years I’ve focused on AI-driven systems, including LLM integrations and retrieval-augmented generation pipelines, plus automation workflows that reduce manual effort and boost operational efficiency. I’m comfortable owning systems end-to-end—from architecture and hands-on implementation to deployment, monitoring, and long-term maintenance—within active production environments. I enjoy collaborating with product managers and analysts to translate operational needs into reliable, maintainable solutions.
