Experience
Centralized Smart Contracts
The ability to evaluate arbitrary contracts based on Monte Carlo simulations was considered a valuable goal at UBS. My manager had estimated six months to complete this project. However, since there were always more urgent projects, this one was never green-lighted.
Over a weekend, I realized that we could use Lua instead of creating our unique smart contract language. The contract written in Lua could be runtime compiled into C and then embedded into our existing C++ Monte Carlo engine. I insisted on my idea and implemented this solution in less than three days. And I received monetary remuneration for this valuable contribution.
