Backend Developer · AI-Driven Development · SDD & TDD
Alajuela, Costa Rica 🇨🇷
Backend Developer focused on building scalable RESTful APIs and microservices with Java & Spring Boot. I use multi-agent AI coding tools daily as a productivity multiplier — orchestrating specialized agents (Planner, Architect, Coder, Tester, Reviewer) to accelerate development cycles without sacrificing quality.
I design systems around Hexagonal Architecture and Clean Architecture, write specs before code (SDD), and tests before implementation (TDD). I also have working knowledge of the Model Context Protocol (MCP) and modern agent harnesses.

Tools
| Area | Details |
|---|---|
| REST APIs | Spring Boot + JPA/Hibernate + MySQL, full CRUD, contract-first |
| Microservices | Eureka Service Discovery, inter-service communication, layered architecture |
| Security | Spring Security — authentication & role-based access control |
| Architecture | Hexagonal (Ports & Adapters), Clean Architecture, SOLID principles |
| AI Workflows | Multi-agent orchestration, prompt engineering, context management, MCP |
| Data Structures | Python implementations — linked lists, trees, graphs, Big-O analysis |
Spec → Tests (fail) → Implement → Tests (pass) → Refactor → Review
- Spec-Driven Development (SDD) — define clear specs before touching code
- Test-Driven Development (TDD) — failing tests first, then implementation
- AI-augmented cycles — agent orchestration to accelerate without losing control
- Clean Architecture — business logic isolated from infrastructure at all times
