My name is Kamil Lelonek,
I'm a Software Engineer
and a Team Leader.

My services

Backend

For me, working on the backend is the most exciting thing. I like to play with different languages and frameworks. At the moment, I’m focusing mainly on Elixir language and Phoenix framework.

Databases

In my opinion, working with (relational) databases is one of the most interesting things in software development. I use mostly PostgreSQL on a daily basis and Redis when it comes to key-value store and caching.

Infrastructure

I’m familiar with configuring custom infrastructure using Terraform and Kubernetes. I always automate deployment and set up continuous integration. I follow infrastructure as code approach in my projects.

Blockchain

Currently, I’m exploring Blockchain-based technologies. I’m building my own Blockchain implementation for educational purposes to teach others the entire concept.

The most important thing for me is to continuously improve.

Let me show you what I do.
