Description

Hello 👋

I am a Backend Software Engineer specializing in Java and Spring Boot, with experience in microservices architecture and REST API development in demanding environments, especially in banking and utilities.

I propose two main service lines:

1️⃣ Development and optimization of APIs and microservices

I develop and evolve robust, scalable, and efficient backend services.

I also perform technical audits and deep performance optimizations.

Technologies and skills:

👉 Java (11/17/21), Spring Boot, Hexagonal Architecture, Microservices

👉 REST API (public and private), integration with external services

👉 PostgreSQL / MySQL / Oracle

👉 Docker, Jenkins, AWS

👉 JUnit, Mockito, Clean Code, SOLID Principles

👉 Observability, traces, and incident resolution in production

🧠 Demonstrated experience improving processes and algorithms by 35% to 60%, and resolving critical incidents by reducing diagnosis and recovery times.

2️⃣ Integration into agile teams for corporate projects

For medium or long-term projects, in full-time or part-time mode.

👉 Development of new functionalities, refactoring, migrations

👉 Technical design, documentation, releases, onboarding

👉 Direct collaboration with clients and multidisciplinary teams

👉 Agile methodologies (Scrum / Kanban)

💪 My focus in all projects:

security, performance, stability, maintainability.

I seek to provide real value and build solid, clear, and easily scalable backend services.

📩 Shall we talk about your project or technical need?

I am happy to collaborate and understand how I can help you.
