Back to original languageAbout Alberto
Backend engineer with over 8 years of experience designing and building high-performance distributed systems. I specialize in microservice architectures with Java and Spring Boot, and in managing technical teams as a Tech Lead.
I have led projects in sectors such as e-commerce and logistics, where scalability and reliability are critical. From architecture design to the integration of complex systems with Kafka, Redis, or relational and NoSQL databases, I bring both strategic vision and technical execution.
As a freelance consultant, I help companies modernize their legacy systems, optimize their backend performance, and build robust and scalable APIs. I work 100% remotely, with clear communication and a results-oriented approach.
