MARCOS ECHAGUE
Backend Java Developer | AI Enthusiast

// About Me
{ Overview }
I'm a passionate Backend Java Developer with a deep love for crafting robust, scalable enterprise applications. My journey in software development has taken me through diverse industries including Banking, Healthcare, and E-commerce, where I've learned to build solutions that handle complex business requirements and high-traffic environments.
Technical Expertise: I specialize in the Java ecosystem with Spring Boot as my framework of choice, building microservices architectures that are maintainable and performant. My database expertise centers around PostgreSQL, and I'm proficient with containerization using Docker and cloud deployment on AWS. Currently, I'm expanding into the AI space, integrating cutting-edge solutions with OpenAI, Tavus, and 11Labs into traditional business applications.
Problem Solving & Creativity: What drives me most is tackling challenging problems that require innovative thinking. I thrive when faced with complex architectural decisions, performance optimization challenges, and the satisfaction of turning abstract business requirements into concrete, working solutions. Every bug is a puzzle, and every new feature is an opportunity to learn something new.
Continuous Learning: The tech world never stops evolving, and neither do I. I'm constantly exploring new technologies, design patterns, and best practices. From diving deep into Spring Security to understanding AI model integration, I believe that staying curious and adaptable is essential for any developer who wants to build truly impactful software.
Team Collaboration: I've learned that the best software is built by teams, not individuals. I excel in collaborative environments where ideas flow freely, code reviews are learning opportunities, and everyone's expertise contributes to better solutions. Whether I'm mentoring junior developers or learning from senior architects, I value the collective knowledge and creativity that emerges from great teamwork.
