Oliver Zehentleitner

I build systems that work - technically sound, security-first, and actually useful to the people who depend on them.

I’m a collaborative engineer who brings people and cross-functional teams together, translates between technical and human perspectives, mentors others, and makes complex topics easy to understand.

Creator of the UNICORN Binance Suite - 6 open source Python libraries for automated trading systems on Binance. 3.3M+ downloads, ~1k GitHub stars, and 390+ dependent public projects. Built and maintained independently since 2019.

Currently pioneering AI-driven open source maintenance with @oliver-zehentleitner-aigent - a controlled AI agent that maintains production code. Documenting what works, what fails, and what it means for engineering teams at technopathy.club.

This work also led to Keep the Why - an open-source initiative and agent skill for preserving the reasoning behind software. It captures architectural decisions, rejected alternatives, workarounds, and operational context during development - or helps recover that knowledge later from existing codebases and their maintainers.

Active in Security Research & Vulnerability Disclosure - Auditing infrastructure, uncovering threat campaigns, and publishing independent deep dives. Notable work includes disclosing the Binance API IP-Whitelist Bypass (listenKey vulnerability), tracking an active infostealer infrastructure in the Nailproxy & Stealc Campaign, and dissecting a targeted malware delivery chain disguised as a Fake Job Interview.
