Back to original languageAbout Florian
You're not looking for a dev. You're looking for someone who takes your problem and delivers a finished product. In production. That works.
This is what I've been doing for 10 years.
What I've delivered:
— Embedded firmware deployed on 150,000+ physical devices per year (Gecko Alliance, global leader, 30-40% market share)
— Field applications used by 250,000+ telecom technicians in 100 countries (EXFO, 95 of the top 100 global operators)
— Multiplayer framework whose technology was acquired by Rockstar Games
— Real-time, offline-first, high-performance systems, designed and delivered autonomously
What this means for you:
— A single point of contact instead of a team of 3-4 devs to coordinate
— Architecture, development, and deployment handled by the same person who understands the entire system
— Products designed for production, not for demos
I don't take on every project. I take on those with real technical constraints: critical performance, real-time, offline synchronization, IoT, distributed systems.
