Backend engineer specialized in Java (Spring Boot) and Python, building scalable, secure and production-grade backend systems.
I design architectures that endure — systems structured for clarity, performance and long-term evolution.
My work integrates clean architecture principles, distributed systems thinking and practical AI capabilities into real-world, production-ready applications.

I treat backend development as systems engineering.
- I design before I code
- I model domains before implementing endpoints
- I optimize for clarity before complexity
- I favor maintainability over shortcuts
- I build with production in mind from day one
Good software is not just functional — it is structured.
- Clean Architecture & SOLID principles
- Domain-driven design thinking
- Secure API development
- Scalable distributed systems
- Long-term maintainability over short-term shortcuts
Open to backend engineering roles, AI-driven product development and high-impact technical collaborations.
