Software Engineer at DarkFlippers
Summary
🤩
Rockstarr3df0x is a software engineer with four years of experience specializing in embedded systems and backend work, notable for contributions to the popular Flipper Zero Unleashed firmware. They have deep hands-on experience modifying core radio control logic and hardware interactions to unblock sub-GHz frequencies, add KeyLoq save/send features, and implement protocol-specific counters like a 20-bit FAAC SLH counter. Comfortable working close to metal, they’ve also extended support for niche remotes (Nice FloR-S) and pragmatic firmware features that improve device interoperability. Their GitHub persona “Unleashed CFW dev” reflects a focus on practical, user-facing firmware enhancements that balance protocol knowledge with low-level implementation. Colleagues can expect a developer who thrives on reverse-engineering constraints and shipping durable embedded features.
