I was working in Buhler Group Milling Solutions department as a tech lead on a project which provides human-machine interface for controlling PLC machines. The PLCs are part of e.g. roller mills, jet mixers, etc. My tasks involved architecture, code design, implementation, mentoring junior developers. I also create, update, optimize and maintain Azure DevOps pipelines. Later I was working in Die Casting team, which develops a HMI for casting automobile parts for world well known clients.

I was contributing to HackerMate.io which provides an automated way to perform (repetitive) ethical hacking / penetration testing tasks (e.g. automate a lot of enumeration/scans), thus saving penetration tester’s time and allowing them to focus on more complicated things. This project’s infrastructure is based on AWS and python3.

I was working on proof of concept solutions - c# projects in energetics field. The project was stopped after 3 months

I was working on a greenfield project – client facing ASP.NET MVC Core application hosted in MS Azure cloud. This application is intended to manage the blood plasma donation, packaging and release process from the beginning (registering the plasma donor) to the end – dispatching plasma batches.

As a part of “MyServices” team I was working on customer facing web application (ASP.NET, Knockout.js, React.js) which provides various network-related services – e.g. network statistics, reports, notifications & alarms, cloud services, video/audio services, etc.

I have been working on my own project in a small team (2 people) - shared shopping list application for Android, Windows Phone.

I have been a part of company which has developed trading platform for banks and financial institutions. As a part of Clearing Team, I was in charge of c# code which ensured communication with Exchanges/Clearing houses (CME, COMEX, NYMEX, ICEU, ICSG, EUREX), implementation and setup of newly created exchanges, maintain documentation, configuration of IBM MQ, AMQP and related test environment (reliability and performance tests).
