01 Introduction
Senior engineering grounded in architecture, clarity, and technical depth.
I’m a senior software developer with deep expertise in backend systems and enterprise application development. I work extensively with PHP, Symfony, Doctrine, Java, Hibernate, and Spring Boot to build reliable applications, APIs, integrations, and business-critical platforms.
My work goes beyond frameworks. I design software around clear boundaries, strong domain models, testable components, and explicit trade-offs. I apply Hexagonal Architecture, CQRS, SOLID principles, Clean Code, and pragmatic system design to keep complex systems understandable and adaptable.
I also bring broad knowledge of computer networks, protocols, distributed communication, security boundaries, and production infrastructure—an important foundation when designing resilient services and diagnosing real-world system behavior.
What I work with
Focused expertise.
Flexible thinking.
From domain modeling and architecture to implementation and production behavior, I design backend systems that remain understandable as complexity grows.
Java Ecosystem

- Refactoring & code review
- Observability & operations
How I approach work
Good software starts before the first line of code.
- 01
Understand
Clarify the real problem, users, constraints, and definition of success.
- 02
Design
Choose a solution that balances speed, simplicity, quality, and future needs.
- 03
Build
Develop in clear increments, communicate openly, and verify behavior early.
- 04
Improve
Measure, learn, refine, and leave the system healthier than it was before.
