About Me
Hi, I'm Kevin Llanos. I’m passionate about building scalable applications, applying DevOps practices, and implementing cloud infrastructure to solve real-world problems. I completed my Bachelor’s in Software Engineering in 2025, focusing on practical skills by building Spring Boot applications, Angular frontends, and delivering AWS cloud solutions. I'm a Software Engineer who's worked across the SDLC, primarily with Java backends, Angular/React frontends, AWS, and DevOps tools, with over 3,000 hours of hands-on development. I’m driven to create software that delivers real value and enjoy collaborating with teams where I can continuously contribute and grow. Always learning, always delivering — I’m the teammate you can count on.
