About me
Hi, I'm Philipp. A full-stack Smart Contract Developer who discovered his passion for programming at age 11 and fell into the crypto rabbit hole while mining Bitcoin at 13. Over 8 years of development experience has led me through the entire Web3 ecosystem — specializing in Solidity, but equally comfortable with backend systems (Node.js, Go, GraphQL) and modern frontend frameworks (Next.js, React).
See what I've,
been working on
Hifi Finance
A Stablecoin-centered, CDP-based RWA lending protocol. Currently engineering DeFi and NFT services involving heavy tokenomics and security focus.
TurtleShell
A "circuit breaker" standard to stop on-chain exploits in real time. As a key contributor, I helped build out the technical implementation and worked with protocols on implementation.
PRBMath
Currently contributing to the fixed-point math library to implement accurate rounding and a higher precision, 27-decimal library number type for financial DeFi apps.
