Hello There!
I’m Michał Łęcicki (aka Maikhel) - software engineer at Visuality. I believe self-improvement, responsibility and clean solutions are necessary to get things done: both in software and real life.
My path
My programming journey started in 2012 with free "Introduction to Java 101" Coursera course. Excited by creating a program that can rotate an image, I got to more serious learning at university. I finished with Bachelor’s degree in IT in 2016, University of Cardinal Stefan Wyszyński in Warsaw.
In 2015, I started working in Weblify as a junior Ruby on Rails developer and in 2018 I moved to Visuality as a software engineer. Surrounded by experienced engineers, I learned and still improve best development practices, applying clean architecture and choosing right design patterns.
As a backend engineer, I’m usually responsible for preparing Ruby on Rails API applications (currently in JSON:API standard), building software prototypes or creating third party integrations (eg. with Pipedrive). Doing devops stuff on Heroku or AWS also happens to me.
Few technologies I met so far include Elasticsearch, Terraform, Beskar, Serverless, R, Golang, ASP.NET.
Recently, I'm taking a closer look at Domain Driven Design and Event Storming.
In addition to blog posts, from time to time I make lightning talks and presentations:

Other
Primary field of my knowledge is psychology - I got psychology Master's Degree in 2015, University of Cardinal Stefan Wyszyński in Warsaw. Several psychology-related topics like stress management, cognitive psychology or productivity still fascinate me. I’m also devoted Getting Things Done method follower.
More or less I speak English and German.
In my free time I play board games, hunt for perfect photo scene, read some good book or just watch snooker. Oh, and I’m a big Star Wars fan.
