Summary

I’m a Full-Stack Engineer building scalable web apps, APIs, and cloud architectures. I focus on Angular architectures, Spring Boot backends, cloud-native deployments, and automated data flows with Python & AI. I work solution-oriented, think in systems, and deliver stable, maintainable software with quality, scalability, and clear code in mind.

Core Focus:

Frontend: High-End Angular (up to v19), RxJS, SignalStore, Clean Code, Nx
Backend: Spring Boot, Java/Kotlin, NestJS/Node.js, Python (FastAPI, Flask)
Cloud-Native: Docker, Kubernetes, Azure, AWS, CI/CD, Helm, Terraform
