Balazs Laczko

Currently working as a Lead Backend Developer at Frankly. I work on the backend of various Danfoss Digital Tools and on data lakes for both Danfoss and Frankly. The backend stack I work with is written in C# .NET, they use MSSQL and SQLite databases and run on Microsoft Azure infrastructure. The data lakes I built run on Databricks and they are written in Python.
I'm the Team Lead of the seven person team that is maintaining these tools. Those responsibilities include sprint planning and management using Azure DevOps, as well as coordinating the releases. I have a managerial role in relation to the junior developers on the team, who I was also responsible for hiring and onboarding.
At a hobby level I worked with Docker, Typescript and JavaScript. I have some experience with frontend development using the Angular framework. These personal projects are hosted on AWS and Cloudflare.
While working at NI, I was developing solutions for testing hardware. I used LabVIEW, TestStand and a wide variety of NI hardware products. The work also involved some hardware design. During that time I was also involved with intern training and mentoring, as well as a bit of teaching analog & digital measurement at the University of Debrecen.
