I help founders and non-technical companies turn software ideas into real products, technical teams, and scalable engineering foundations. That means more than writing code. I can help define what should be built, how it should be built, who should build it, and what process is needed to get the first real product out. I’m a Senior Full-Stack Developer, Software Architect, and hands-on technical leader from Germany with 15+ years of experience building SaaS platforms, custom CMS solutions, internal tools, dashboards, onboarding flows, integrations, and complete product foundations. Core stack: TypeScript, React, Next.js, Node.js, PostgreSQL/MySQL, GraphQL, AWS, Vercel, Supabase, Docker, CI/CD, and modern AI-assisted development tools. Most software projects do not fail because nobody can write code. They fail because the wrong foundation is built: unclear product direction, fragile architecture, bad hiring, weak processes, messy business logic, poor UX, underestimated integrations, or AI-generated code nobody can maintain. When to Involve Me I am most valuable before major product, team, and technical decisions are locked in. For non-technical founders or companies, one common mistake is hiring a project manager, designer, or developer before understanding what the product actually needs. A PM, designer, or developer can all be useful — but only when the technical foundation, product scope, architecture, and collaboration model are clear. I help you decide: - what should be built first - what can wait - what architecture makes sense - what team roles are actually needed - whether AI-assisted design is enough for the first phase - how to organize development without unnecessary overhead - where AI can save time without creating technical debt What I Can Help With - Building a technical/product department from scratch - Hiring and screening developers, designers, and technical roles - Setting up development processes, code quality standards, CI/CD, and project workflows - SaaS MVPs and production-ready web applications - Custom CMS platforms and content management workflows - Admin panels, dashboards, and internal business tools - Multi-step onboarding forms and complex user flows - CRM, payment, email, analytics, monitoring, and third-party API integrations - Business process automation and workflow software - Next.js/Vercel apps, Supabase-backed MVPs, serverless APIs, and startup infrastructure - AI-assisted product features and AI workflow integration - Technical rescue of unstable or hard-to-maintain applications What You Get - Product and technical leadership, not just ticket execution - Stable architecture that can grow with your product - Clean TypeScript, React, Next.js, and Node.js code future developers can maintain - UX-focused implementation that feels intuitive, reliable, calm, and effortless to use - Complex business logic translated into clear workflows, data models, and maintainable systems - DevOps, CI/CD, deployments, monitoring, analytics, SEO basics, and code-quality automation where needed - AI-assisted visual support for logo concepts, website design direction, UI ideas, copy, SEO, and polished product presentation when useful How I Work With AI I use AI heavily, but as a professional engineering tool — not as a replacement for engineering judgment. AI helps me move faster, explore options, generate boilerplate, improve UI concepts, write tests, and reduce repetitive work. But architecture, UX decisions, code quality, and final implementation stay under my control. I use custom workflows, coding standards, architecture rules, review processes, and multiple refinement passes so the final result stays maintainable and feels like software I would have written myself. Highlights - Built and led the entire tech/product department for a social impact platform in Germany, including hiring, product direction, processes, architecture, infrastructure, and core implementation - Built a complete SMS marketing platform as co-founder and lead engineer, including a custom ORM and automated pipeline from database schema to frontend SDK - Built custom rich text editors and CMS-like systems used by thousands of users - Delivered projects across travel, e-commerce, healthcare, government, social impact, workflow automation, and startup SaaS - Led developers, mentored teams, screened candidates, and introduced better engineering processes Who I Work Best With - You are a founder or non-technical company that needs technical/product leadership - You need help turning a business idea into a real product and technical foundation - You care about quality, UX, maintainability, and long-term scalability - You have workflows, integrations, dashboards, onboarding flows, or business logic that need thoughtful planning - You want AI-assisted speed, but not AI-generated technical debt If you need a hands-on technical partner who can help plan, build, hire, organize, and launch. Thats me.
