My career so far, written as a network traceroute: from C# work at Yara in 2015, through Go, Erlang and Elixir roles, to DevOps at Simanban today.

01About

From the BEAM to the Linux kernel.

I'm a software engineer with more than a decade of building backends, most of it on real-time messaging and distributed systems. I started on the Microsoft stack with C# and ASP.NET, worked with Go and Node.js, then spent five years on the BEAM writing Erlang and Elixir.

At BisPhone and Pars Telecom I worked on messengers serving large numbers of live, concurrent connections with Erlang, Ejabberd and Cassandra. Remote Elixir work followed: OQTO, a platform linking partners to the finance engine at ClubCollect, the chat platform behind hubber.live, and real-time LiveView dashboards at Marko.

Today I work as a DevOps engineer at Simanban. I run CI/CD and Kubernetes clusters, practice GitOps with ArgoCD, provision virtual machines on Proxmox and VMware with Terraform and Ansible, and keep an eye on everything with Prometheus and the ELK stack. I write up what I learn as practical guides.

I hold a master's and a bachelor's in software engineering, and alongside my day job I've mentored early-stage teams at Sharif Accelerator and Avatech.
