About Juan Martin

Hello, I am focused on creating robust, efficient, and secure backend solutions. My differentiator is that I combine solid object-oriented programming skills with experience in Quality Assurance (QA) and Cybersecurity, which allows me to guarantee clean, tested, and high-quality code from day one.
In the development area, I specialize in:

Backend: Java (OOP and Functional Programming), Spring Boot, Spring Security (BCrypt), Spring Data JPA, and Hibernate.

APIs & Architecture: Design of scalable RESTful APIs, DTO patterns, layered architecture (MVC), and SOLID principles.

Databases & DevOps: SQL (MySQL, H2), Docker, Docker Compose, and Nginx.

Advanced Integrations: Connection of Artificial Intelligence APIs (experience integrating Google Gemini API).

Code Quality and Security:
I hold the professional certification in Cybersecurity from Google and training in QA Testing. I design automated and unit test suites using JUnit 5, Mockito, and MockMvc to ensure software stability against any changes.

I am passionate about solving complex problems, optimizing processes, and documenting in detail (Swagger/OpenAPI) to facilitate teamwork. I work 100% remotely and am available to add value to your next project

    May 2026 - June 2026 (1 month)
    San Miguel de Tucumán, Argentina
    I designed the logic and architecture of an autonomous AI agent integrated with WhatsApp using the Google ADK ecosystem and the Gemini 2.5 Flash model.

    I implemented robust identity validation flows (ID Card/Tracking Number) aligned with security and data protection regulatory frameworks, ensuring a closed processing environment (RAG) that safeguards information privacy.

    The project was a one-week corporate challenge using agile methodologies for its design. The result of this project was that we secured third place among 9 different teams.

    January 2026 - February 2026 (1 month)
    San Miguel de Tucumán, Argentina
    I developed a RESTful API for managing clients, appointments, and complex business logic (such as preventing schedule overlaps).

    I structured the project under a Layered Architecture (Controller, Service, Repository) and applied DTO patterns to decouple database entities from API responses, enhancing security.

    I implemented a global exception handler (@ControllerAdvice) to standardize HTTP responses for runtime errors.

    I built a comprehensive suite of unit and integration tests using JUnit 5, Mockito, and MockMvc, achieving high code coverage.

    San Miguel de Tucumán, Argentina
    I designed and implemented a complete backend REST API using Java 21, Spring Boot, and MySQL, along with an interactive React administrative panel.

    I configured an advanced security system using Spring Security, managing role-based access control (ADMIN/USER), BCrypt key encryption, and strict CORS policies.

    I integrated Artificial Intelligence capabilities through the Google Gemini API for automatic generation of marketing and social media drafts.

    I containerized the entire architecture using Docker and Docker Compose, configuring Nginx as the web server to ensure fast and replicable deployment in production environments (Cloud/VPS).
