Profile: https://flows.cv/dimos

I’m a Software Engineer with over a decade of experience specializing in large-scale distributed systems. My work spans identifying creative solutions to ambiguous business problems, designing and building highly available and scalable  software systems, and leading high-performing engineering teams. I enjoy balancing hands-on technical work with mentoring and team leadership.

Outside of work, I occasionally share thoughts on technical and broader topics on my blog: https://dimosr.github.io/blog. 

I’ve also authored a book on distributed systems for practitioners: https://leanpub.com/distributed-systems-for-practitioners.

Areas of expertise include:

- Software design and architecture, distributed systems, concurrent and multi-threaded systems

- Cloud technologies (AWS, Azure), containerization (Docker, Kubernetes), data platforms (Kafka, SQL/NoSQL)

- Technical leadership focused on building empowered, self-organizing teams

- JVM ecosystem (Java, Kotlin)

Favorite quote:
"γηράσκω δ' αἰεὶ πολλά διδασκόμενος" — "I grow old always learning many things."
