About me
About With over 17 years of experience in software development, I've honed my skills in a wide range of technologies. I'm a master of Go and Node.js, with a strong proficiency in Java, Google Cloud, Azure Cloud Platform, and PHP. I've built scalable APIs and microservices, and have a knack for designing systems that are robust and efficient. I've developed customized websites, e-commerce platforms, and complex systems for monitoring city indicators and classifying companies based on pollution levels. I've also worked on platforms to manage schools and students, and developed microservices using the CQRS pattern. As a versatile problem solver, I deliver robust and efficient solutions across backend, frontend, and mobile projects. Ready to exceed expectations on your next project.
