01 — Positioning

Where Bradford is headed.

Career-long specialist in replacing manual operational work with production-grade automation and tooling across Linux, BSD, and cloud infrastructure. Deep systems expertise (kernel, filesystems, clustering, HA) combined with polyglot development (Python, C, C#, shell) deployed at Fortune 500 companies.

What Bradford brings
  1. 01Linux/BSD kernel and systems internals (30+ years)
  2. 02Production automation at scale — replacing manual ops with resilient tooling
  3. 03Polyglot infrastructure coding (Python, C, C#, shell, Ruby)
  4. 04High-availability and clustering architectures (DRBD, Heartbeat, GlusterFS, CARP)
  5. 05Legacy system rescue and migration (Solaris SPARC, Oracle, DB2 → PostgreSQL)
02 — Proof

The receipts.

Numbers first. Every metric below is something Bradford shipped or drove — not a claim, an outcome.

  • Proof 01
    Built automation over Hive, Pig, Spark, Hadoop; migrated legacy Nagios to Icinga2 with custom conversion tooling
    American Express: Big-data and observability modernization
  • Proof 02
    Level-3 ownership of autofs, PPDD, dmidecode; rewrote Perl ypcat/match for LDAP in C (3,200 lines Perl → ~700 C, significant performance gain)
    Cadence: Open-source upstream contributions and performance rewrites
  • Proof 03
    Reduced Linux licensing cost ~90% through strategic administration and Satellite/Spacewalk deployment
    Encore Capital: Linux licensing cost reduction
  • Proof 04
    Designed risk-free migration plan for aging system that could not be safely shut down; automated legacy codebase conversion (~5K C, 10–30K Perl, ~50K Python) to C# on Red Hat Linux
    Medtronic: Rescued business-critical Solaris SPARC application
  • Proof 05
    Built C# automation auditing fleets of servers for version drift and configuration errors; generated automated remediation reports across enterprise deployment
    Schwab: Server drift detection and compliance automation
