Lefteris Karageorgiou — Co-Founder
I'm Lefteris, a Senior Solutions Architect at Amazon Web Services and the author of the book "Mastering Event-Driven Microservices in AWS". I have over 15 years of experience in Software Engineering and I specialize in Serverless computing, Microservices, Event-Driven Architectures, and Java. I’m also the co-owner and major contributor of the “Java on AWS Lambda workshop”. I'm passionate about sharing my knowledge and expertise through various channels. I frequently speak at technical conferences (AWS re:Invent, AWS Summits, Devoxx, Geekle), discussing topics like Serverless, Event-Driven Microservices, and Java. I've also contributed as a Technical Author for Java Code Geeks, one of the most popular blogs for Java Programmers. Throughout my career, I've successfully led the migration of large monolithic systems to event-driven microservices architectures. In 2019, I Co-Founded a startup where I built the entire platform with Serverless on AWS and the MVP in less than 3 months with zero development cost. I’ve also trained over 200 individuals on the AWS cloud platform as an AWS Tech Instructor. I help people build a successful and fulfilling cloud career that stands out and attracts employers. My goal is to empower Cloud professionals with the knowledge and skills to design, build, and operate resilient, scalable, and fault-tolerant systems using AWS services and modern architectural patterns. 📚 Check out my book "Mastering Event-Driven Microservices in AWS": https://a.co/d/9KDRQfv 💻 Explore my technical articles on Java Code Geeks: https://examples.javacodegeeks.com/author/lefteris-karageorgiou/ 📺 Watch my Devoxx session “From self-managed to fully-managed in AWS: Migrate your Spring Cloud microservices to AWS": https://www.youtube.com/watch?v=Xd34kCXEQzs 🖥 Watch my Geekle session “How I built my startup MVP with AWS Serverless in less than 3 months”: https://youtu.be/eFn7AuqpnlU?t=984 🚀 Check out the “Java on AWS Lambda workshop”: https://github.com/aws-samples/aws-lambda-java-workshop Follow me to learn more about #CloudComputing #AWS #Serverless #Event-Driven Architecture #Microservices #Java.
