Enthusiastically embracing both the creation of new projects from scratch and the enhancement of existing ones, I bring versatility and depth to the development process. My enjoyment in programming is rooted in the philosophy of Robert Martin: "Good code is like a love letter to the next developer who will maintain it." This ethos guides my approach, ensuring my code is not just functional but also clear and maintainable.

As a Java maestro and experienced DevOps Engineer, I specialize in building scalable and efficient systems, blending backend expertise with deployment strategies. My hands-on experience spans AWS, Google Cloud, and the Spring ecosystem, enabling me to deliver robust microservices architectures and automate infrastructure provisioning. I also have a keen focus on cost optimization, having achieved up to 40% savings in cloud expenses.
