Portrait of Georges Yvan Bahanack

Hi, I'm Georges Yvan Bahanack

I design and build software products

I wrote my first line of code at 12 and never stopped. Today I lead engineering at SIMBTECH France, designing multi-tenant SaaS platforms, healthcare systems and AI-powered products — from the database schema to the mobile app.

About me

I've been coding since I was 12 — and never stopped.

I'm a software engineer who enjoys owning the whole problem: understanding the business, designing the architecture, writing the code and shipping it to real users.

As CTO of SIMBTECH France SAS I architect and build platforms for our clients — point-of-sale and ERP systems, HR and school management software, a telehealth dermatology platform, rental management, e-commerce and AI chat assistants.

I hold a Bachelor's degree in Artificial Intelligence from ESIIA Paris and I'm in my 4th year of Computer Engineering at ENSPY Yaoundé, where I also contribute to the Club Génie Informatique — building its platforms and teaching other students.
