Rebuilt a syslog forwarder, eliminating 5 critical security flaws
An enterprise security product shipped a syslog writer/parser/forwarder with serious liabilities: an unsupported, end-of-life Python runtime, an ancient base container (Debian 7), and — most critically — credentials written to disk in plaintext. The component was rigid, heavy, and a security incident waiting to happen.
Designed and built a ground-up replacement in Python 3 that resolved every identified flaw. Added flexibility the predecessor lacked — letting customers supply their own validated queries against the read-only database instead of being locked to a static query. Shipped with its own automated test framework and a proper installer with logging. QA'd across 10 different *NIX distributions (it even ran on Solaris 10).
Cut the footprint from 50 MB+ to ~5 MB. Deployed to a major enterprise customer during beta with zero support tickets filed. Led the integration-engineering effort through to production and final documentation. The release became a Professional Services install package generating $50K+ in revenue.
