About David
🎯 Senior Fullstack Developer & Software Architect (.NET, Angular/React, Azure)
10+ years helping companies build solutions that work, scale, and last.
I’m a fullstack engineer specializing in Microsoft technologies (.NET 6/8, C#, SQL Server) and modern frontend frameworks (Angular, React, TypeScript). I design and develop robust, scalable web and desktop applications, integrating Azure cloud services and applying clean architecture principles, DDD, and microservices when needed.
My background spans insurance, healthcare, fintech, industrial automation, and aviation—leading platform modernizations, building high-performance APIs, and ensuring long-term maintainability. I bring a strong technical foundation, product awareness, and attention to detail to every project.
✅ What I bring:
- Stable, secure, and scalable backend solutions
- Modern, responsive UIs connected to efficient APIs
- Integration with external services: payments, communication, AI, etc.
- Real-world experience with architecture, testing, CI/CD, and Azure deployments
- Proactive, autonomous mindset — ideal for projects that need momentum
I work well as a solo contributor, technical lead, or extension to your existing team. If you’re looking for someone who understands business, product, and code — and delivers real value from day one — I’m ready.
