What our community is saying

"I am a software developer with experience in Front-end , I tried Wilco to start my journey as a full stack developer, I loved the practical approach of teaching/ skill development on industry level provided by this platform. I learned Python, Monitoring and Backend and eagerly waiting for new quests to open."

Prasoon Mahawar

Software Developer

"Wilco gives me the opportunity to challenge myself in a joyful and meaningful way that was hard to reach otherwise as a junior developer."

Oryam Nehoray

Web Developer @ Webiya

"Learning the fundamentals of Git and GitHub was super confusing when I first learned to code. I didn't experience many situations where I'd open pull requests and collaborate with a team. Wilco simulates that environment and enables new developers to gain knowledge of industry standards."

Rizel Scarlett

Developer Advocate @ Github

"Wilco completely succeeds in what it sets out to be: a realistic simulation of integrating a junior developer into a company. The guided approach to all of the traditional first steps (setting up an environment, contributing to the first task...), makes it easy to feel the sense of progress while still giving lots of room to explore and try to figure things out on one’s own."
