What I do
Modular Architecture
Clean, reusable components designed to reduce coupling, clarify responsibilities, and scale with the codebase.
Cloud-oriented Engineering
Practical experience with enterprise systems, data flows, deployment-aware design, and cloud ecosystem concepts.

Enterprise backend engineering
I work on backend systems where maintainability, data flow, integration, and long-term evolution matter more than short-term shortcuts.
- Java/Spring backend development
- REST APIs and service-oriented design
- SQL/NoSQL data access and structured data flows
- Modularization of legacy or complex business logic
