Sergio T.

Backend engineer with 4+ years of experience building distributed systems in production.

I have worked on cloud infrastructure and telecommunications, designing microservices, event-driven architectures, and REST APIs that have successfully solved real-world problems of performance, security, and scalability at scale.

My main stack includes **Java and Spring Boot, Kafka, PostgreSQL, Redis, Docker, and Kubernetes**, with additional experience in TypeScript and Angular for full-stack projects. I have applied advanced design patterns, hexagonal architecture, and security best practices such as OAuth2, JWT, and Keycloak in real production environments.

In the cloud, I work with AWS and Vercel, with AWS Cloud Practitioner certification. I have practical experience in agent-based programming and am currently training in machine learning and applied artificial intelligence.

I work autonomously, adapt quickly to the client's context, and am committed to understanding the business problem before proposing technical solutions. I deliver clean, documented, and maintainable code.

Available for one-off projects or recurring collaborations, primarily remotely.

I can work in Spanish and English.
