I am a software developer who loves to write, and read pretty code. However, sometimes that isn't always a possibility. I am not afraid to get my hands dirty and get the work that is necessary done. I have always had a passion for helping people learn. Because of that, I have picked up a few mentees at work who I have already improved their ability to code surpassing what their managers thought was even possible.

I work with Go. I am one of the top 1% Go answerers in stack overflow. I am the author of the book "Effective Concurrency in Go" from Packt Publishing. Before starting my own company working on privacy technologies, I worked for Red Hat for over a decade where I developed back-end frameworks and services using Go and Java. I developed several open-source frameworks and tools ([lightblue](https://github.com/lightblue-platform), [jcliff](https://github.com/bserdar/jcliff), [took](https://github.com/bserdar/took), [watermelon](https://github.com/bserdar/watermelon), etc.) I can diagnose and solve many back-end programming problems in Go, especially related to concurrency and code architecture. I can help with the overall architecture of distributed systems, database related problems (especially with Mongodb), containers (Docker), Kubernetes, JSON/XML, text processing, data processing applications, gRPC, API development, REST, data structures and algorithms.
