Florian Cäsar is Software & Distributed Systems Engineer at Radix. Creator of an interactive machine learning framework, a high-performance distributed ledger for decentralised finance and a published indie puzzle game. I like to make things happen. I've made some interesting stuff over the past 10 years, failed at even more things and learned a ton. The things I made (or helped make) include a published indie puzzle game, an educational machine learning framework and a decentralised ledger (think Blockchain but better). Here's a highlight reel: I made an indie puzzle game that was publicised as one of the "most promising games of the month". I designed and developed all aspects of this game; low-level particles up to high-level game scripting and editor tools. Managed a team consisting of a programmer (me), artist and a musician and worked on this project for over 2 years. I made a machine learning framework from scratch. It featured automatic differentiation, GPU-support, graphical interactivity and extended support for deep learning out of the box and a bunch of other fancy stuff. This also earned me some awards, like the first place in the two largest national science competitions and third place in the largest European competition (EUCYS). I made a decentralised ledger. Working with the core team at Radix, we researched, architected, designed, developed and tested a new type of distributed ledger for decentralised finance applications. I significantly contributed to demonstrating the superior performance of this solution with a public performance test of over 1 million transactions per second which helped secure over $4M in funding for the company.
