About Mike

Hello! đź‘‹
I love cracking complex problems, designing thoughtful architectures, and creating real value through code. There's no standing still for me: I'm always curious, constantly trying out new tools, and keeping my knowledge up to date to have the right tool ready for every problem.
đź’» My technological foundation (Core Stack):
• Frontend: React, TypeScript, SPA development
• Backend: .NET (C#), RESTful APIs, scalable microservices
• Cloud & Infrastructure: AWS (Architecture, Deployment, Serverless)
🚀 My view beyond the horizon (Current Favorites):
Besides my core stack, I've been working intensively and with great pleasure with state-of-the-art web and infrastructure technologies recently:
• React Native (for high-performance, cross-platform mobile apps)
• Astro (for extremely fast, modern websites)
• Cloudflare & Hetzner (for lightning-fast edge computing and smart, extremely cost-effective hosting architectures)
🤝 How I work & What I offer you:
I work as a part-time freelance professional (approx. 20-30 hours / week). For you, this means: You bring deep, well-founded full-stack knowledge on board – ideal for projects that don't necessarily require a full-time resource.
I am perfectly suited for:
• Startups that want to get an MVP (web or mobile) out quickly and cleanly.
• Agencies looking for a reliable expert for complex backend (.NET) or cloud topics (AWS) on demand.
• SMEs that need modern internal tools or dashboards.
I place great importance on clean code, transparent communication, and pragmatic, goal-oriented solutions. Whether we're setting up AWS infrastructure, building a new frontend in React/Astro, or optimizing a C# backend – I always think from the product's perspective.
Sounds exciting? Let's talk about your project over a virtual coffee. I look forward to your message!
