Gregory K.

I’m a Full-Stack Software Engineer with 6+ years of experience building reliable, scalable, and data driven products, from IoT devices to AI powered SaaS applications. I have helped startups go from concept to launch, developing complete solutions across firmware, backend, frontend, and cloud infrastructure. Recently, I led the backend for H2YO Europe’s IoT health station, which now powers thousands of devices and has served over 2 million real world transactions. My stack spans both MERN and Next.js, Supabase ecosystems, enabling me to rapidly build and ship MVPs that scale into production grade SaaS platforms. I also work extensively with Langchain, LangGraph and N8N to design intelligent workflows, integrate AI pipelines, and automate data processing. What I Build - End to end MVPs and SaaS platforms (Next.js, Supabase, Node.js, React) - AI enabled tools and automations using Langchain, LangGraph & N8N - Scalable APIs, authentication systems, and data pipelines - Cloud deployments with CI/CD and containerization (AWS, AZURE, GCP) Tech Toolbox Node.js | React | Next.js | Supabase | MongoDB | PostgreSQL | TypeScript | Langchain | LangGraph | N8N | Docker | AWS | CouchDB | Xano I’m passionate about rapid prototyping, systems reliability, and turning complex ideas into polished, production ready products. Whether you need an MVP developer to validate your startup idea or a SaaS engineer to scale an existing product, I can help you build fast, iterate smarter, and launch with confidence. Let’s turn your idea into something people can use. 🚀
