About

I'm Wiktor Feduń, a Senior Software Engineer at FLYR, bringing extensive experience in backend engineering, data analysis, and cloud technology. I specialize in Python, SQL, Airflow, Flask, Docker, Google Cloud, AWS, and Big Data, which has allowed me to contribute significantly to enterprise applications and scalable backend systems.

Before joining FLYR, I held various technical roles at companies like AirHelp and Revolut, where I developed microservices and automated business processes using Python, AWS, and Docker. At AirHelp, I built bots and data-driven systems to support business operations, while at Revolut, I focused on quality analysis and automating key performance metrics for compliance teams.

In addition to my role at FLYR, I run uczesieprogramowac.pl, a mentoring platform I founded to support newcomers to the tech industry by providing guidance, practical skills, and motivation. I’m passionate about sharing my insights through my YouTube channel - Wiktor Fedun Tech (it's in Polish), and blog articles in both Polish and English.

I’m also CKAD certified and actively engaged in tech communities, where I regularly share my knowledge and mentor aspiring engineers.
