About us

Tupu is a non-profit initiative run by a few volunteers in their free time. If you are registering as either a mentor or a mentee, you will hear from one of the people below.

Monica Sarbu

Monica Sarbu

Monica started Tupu after leaving Elastic when she realized that she will miss the internal mentoring program at Elastic and that no other free mentorship platform exists. In her day job, Monica is the founder and CEO of Xata.io, a serverless database for Jamstack and Low-Code applications.

Previously, she has founded Packetbeat, an open source monitoring system, which was acquired by Elastic in 2015. At Elastic, she served as Director of Engineering, leading several teams, including the teams developing the popular open source projects Logstash and Elastic Beats.

Outside work, she enjoys spending time with her daughter and traveling the world.

Madalina Tepelmann

Madalina decided to enter the computer world after seeing a movie about hackers. Since then, she hacked multiple software engineering departments starting with quality assurance and continuing with development. Searching for a bigger playground she discovered customer’s support.

Currently she is a member of the Spirent team teaching and assisting customers and colleagues to hack the TTCN-3 language and products developed with it across different domains like Telecommunications, Automotive and Industrial Automation.

Madalina enjoys hiking (partially because at the end of any tour there is a tasty treat waiting), biking with the speed of light on the way to her child’s school and any race she is challenged to by her child.

Tudor Golubenco
