Stefan D.

Senior Software Engineer | React & Node | Web & Mobile

I build complete software products from front to back. That includes the frontend, backend, databases, infrastructure, deployment, and the overall system architecture. Working with one developer who understands the entire stack makes development simpler and avoids the overhead of coordinating multiple specialists. With 6+ years of professional experience, I've built and maintained production systems across web and mobile. My focus has always been on building software that's reliable, maintainable, and easy to extend as products grow. I care more about solid architecture, clean code, and long-term maintainability than chasing whatever framework is popular at the moment. I also use AI coding tools as part of my workflow. Used properly, they can significantly speed up development and improve overall productivity. The value doesn't come from the tools themselves—it comes from knowing when to trust them, when to challenge them, and how to use them without compromising code quality. Experience and engineering fundamentals still make the difference. Core technologies: TypeScript / JavaScript / Python React / Next.js / Vue.js / React Native Node.js / NestJS / Express.js SQL / NoSQL Git / Docker / VPS / Cloudflare / AWS / Claude Code If you need someone who can take your product from idea to production—or jump into an existing codebase and move it forward—send me the details, and I'll tell you honestly how I'd approach it.
