Service / backend and integrations
Backend and integrations that connect operations
I build services and APIs that connect enterprise products, data and operations. I work with new and existing systems, taking care of contracts, authentication, observability and incremental evolution. The goal is an understandable, stable integration—not another layer that becomes difficult to maintain.

What I can contribute
- REST APIs and JWT-based authentication
- Microservices and event-driven processing
- Integrations across existing systems
- Incremental migrations from legacy services
How I work
- Map consumers, data and boundaries before choosing an implementation.
- Define clear contracts and errors that make failures diagnosable.
- Separate low-risk changes from migrations that require coordination.
- Deliver documentation and tests that make service evolution safer.
Related experience
I have built microservices and APIs with Java, Vert.x, Spring Boot, Node.js and NestJS for telecommunications and enterprise operations, including event-driven patterns and gateways with JWT authentication.
