I love breaking down complex problems into small, understandable pieces. I want you to leave our sessions feeling more capable than before we met, so that you can confidently move forward knowing that if you encounter a similar problem again, that you're prepared and ready to tackle it yourself. With over 13 years of corporate experience, including 5 years working extensively with React and TypeScript, I bring a wealth of practical knowledge to our sessions. Recently, I left the corporate world to pursue my passion for developing a Crypto Video game full-time. In my free time, I’m dedicated to helping others enter the tech industry by demystifying the often intimidating barriers it presents. My goal is to empower you to overcome any obstacles you encounter, giving you the tools and confidence to solve similar problems independently in the future. I'm excited about the opportunity to work with you and help you achieve your goals in the tech industry. Looking forward to our journey together!
I help startups and product teams build, stabilize, and scale AI-powered SaaS platforms. I am a Senior Full-Stack / AI SaaS Engineer with 11+ years of experience across TypeScript, React, Next.js, Node.js, PostgreSQL, Supabase, Redis, Go, cloud infrastructure, and LLM-powered workflows. I work best in small, high-ownership teams where I can take ambiguous requirements, understand the existing system, and ship production-ready features without breaking what already works. My recent experience includes AI assistants, realtime systems, multi-tenant SaaS platforms, Stripe billing and entitlements, class scheduling APIs, secure file access, webhooks, browser automation, backend integrations, and production debugging. At MSBAI, I helped build AI products for scientific and engineering workflows, including an AI assistant for CFD simulation planning, a mining-permit drafting assistant, and an HPC/supercomputer resource-management platform. I worked on LLM workflows, retrieval systems, realtime desktop sharing, resumable job pipelines, and admin tooling. At LSAT Demon, I worked on production TypeScript systems for class scheduling, student registration, plan-based access control, recurring class behavior, downgrade cleanup, Zoom workflows, and regression-safe service logic. At Handlet, I work on an AI-native SaaS platform using Next.js, Supabase, Stripe, realtime inbox workflows, Unipile integrations, secure attachment access, entitlement enforcement, RLS, webhooks, migrations, and CI/CD. I bring strong full-stack execution, backend architecture, product sense, testing discipline, and the ability to move fast without creating long-term technical debt.
I'm a fractional CTO and tech lead based in Munich with over 15 years of experience across the full stack. I started as a self-taught coder writing mIRC scripts and freelance tools, then moved through agencies and product teams in Belgium and Portugal before becoming CTO of BEPRO Network, where I built the technical foundation for a Web3 platform and stayed on through its acquisition by TAIKAI. As CTO, I led the product lifecycle end to end, from roadmap and architecture decisions to mentoring engineers and running agile delivery across a distributed team. I care about clear communication with founders and stakeholders just as much as the technical work itself. Today I split my time between fractional CTO engagements and hands on development. Recent projects include diagnosing and fixing critical performance issues for a SaaS product (cutting load times from 5 seconds to under 1 second), leading Stripe payment integration, and rescuing a stalled early stage MVP and shipping it to production. I also build custom Claude AI skills and internal AI tooling, and I'm currently working across .NET, TypeScript, Terraform and GCP. What I bring: strong full stack engineering (TypeScript, Node.js, React, .NET), cloud architecture (GCP, AWS), hands on team leadership, and the ability to move between strategic planning and writing code myself. I'm comfortable owning a technical roadmap or just shipping features, depending on what the project needs. Available now for fractional CTO roles and hands on contract work, remote first.
Do you need someone that knows the ins and outs of AI, Cloud, Software Engineering, System Scaling, and Design? I'm an experienced AI Engineer, Cloud Expert, Coder, and User Experience Researcher that has worked for JPMorgan Chase, the United Nations, American Express, AT&T, and Lockheed Martin as well as for several startups and small businesses. Additionally, I've mentored people running successful startups and working in companies like Anthropic.
