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.
Route to Infrastructure Automation Engineer, Senior DevOps Engineer, Senior Site Reliability Engineer teams building high-throughput services in the candidate's core stack.
Linux/BSD kernel and systems internals (30+ years). Production automation at scale — replacing manual ops with resilient tooling. Polyglot infrastructure coding (Python, C, C#, shell, Ruby). High-availability and clustering architectures (DRBD, Heartbeat, GlusterFS, CARP).
SRE / DevOps, Systems Engineer, Infrastructure / Cloud Engineer, Platform Engineer.
Remote-first. Hybrid considered for high-alignment local roles. Based in Phoenix, US.
Currently: Automation Developer.
Recruiter screen → hiring-manager review → technical conversation around American Express: Big-data and observability modernization, Cadence: Open-source upstream contributions and performance rewrites, Encore Capital: Linux licensing cost reduction.
Bradford's work in SRE / DevOps, Systems Engineer, Infrastructure / Cloud Engineer translates directly into adjacent domains with similar architecture, scale, and reliability needs.
This reusable proof index maps common senior/staff engineering requirements to candidate proof. Role-specific addenda extend — not replace — this base matrix.
Requirement: Deliver on american express: big-data and observability modernization at production scale.
Proof: Built automation over Hive, Pig, Spark, Hadoop; migrated legacy Nagios to Icinga2 with custom conversion tooling
Requirement: Deliver on cadence: open-source upstream contributions and performance rewrites at production scale.
Proof: Level-3 ownership of autofs, PPDD, dmidecode; rewrote Perl ypcat/match for LDAP in C (3,200 lines Perl → ~700 C, significant performance gain)
Requirement: Deliver on encore capital: linux licensing cost reduction at production scale.
Proof: Reduced Linux licensing cost ~90% through strategic administration and Satellite/Spacewalk deployment
Requirement: Deliver on medtronic: rescued business-critical solaris sparc application at production scale.
Proof: 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
Requirement: Deliver on schwab: server drift detection and compliance automation at production scale.
Proof: Built C# automation auditing fleets of servers for version drift and configuration errors; generated automated remediation reports across enterprise deployment
Requirement: Ship work that requires linux/bsd kernel and systems internals (30+ years).
Proof: Demonstrated at prior roles.
