Baris Ersezer


Baris was always fascinated by technology and curious about how things were built. He started coding when he was a teenager and made this passion his job. His appetite to new challenges made him travel and work in different countries and companies. He created his own company to taste the entrepreneurship and learned a lot from this diverse experiences.

Currently he believes that all the new technologies invented for different purpose like games, entertainment, transportation, etc. could help to understand people needs by analyzing the collected data and provide high value digital healthcare. The best solution for him is when the solution is fully integrated within the life (digital life) of users instead of expecting them to learn one more application.

Results-oriented Team Leader with expertise in software development, quality engineering, and change management. Effective at managing diverse team members to accomplish business goals.
Detail-oriented and efficient, with strengths in both project and analyzing the need of customers.
