About me

I’m Iwan Gulenko, and I have personally placed hundreds of people in tech job opportunities since 2016. I am a “Prüfungsexperte EFZ Informatik” in the Canton of Zug. Based in Zug city, I am happy to meet you personally in Zurich or anywhere in Switzerland (I particularly enjoy Lake Zug, especially in winter).

I can assist you in finding the right talent and you can leverage my network in technical roles such as Java, .NET, Python, JavaScript (frontend or full-stack), Product Management, Scrum Masters, “Executive Tech” (my favorite), and even SAP roles.

Before this, I worked hands-on in the industry as a programmer for many years, so I know exactly what I am recruiting for. If you need tailored hiring assistance, feel free to contact me anytime at  or  +41 77 986 9000.
