Senior Software Development Engineer - Amazon Web Services

September 2022 - Present Built and operated security-critical identity infrastructure for AWS IAM, managing access control for 500,000+ service identities across all AWS global and government cloud regions.

• Performance: Traced a multi-year latency problem through 3 service layers to an unnecessary serialization round-trip. Eliminated root cause and compounding inefficiencies across 4 packages. 91 to 98% reduction in worst-case latency (27 min down to 37s page loads, 19 min down to 97s commits).
• Security automation: Led a 10-milestone, 5-team project replacing a manual 3-week pipeline with near-realtime automation. Designed approval workflows, ran a 157-team verification campaign, unblocked changes frozen for 3 years. Zero incidents since (previously 9 in 3 years).
• Incident response: Led 12-hour incident response across 5 isolated cloud regions. Coordinated rollbacks, drove real-time recovery, authored post-incident analysis, and implemented automated guardrails that caught a secondary issue 2 months later.
• Platform expansion: Launched identity service in a government cloud partition. Fixed cross-region credential bugs, built data transfer infrastructure, parallelized test suites (60 down to 20 min) establishing the pattern used for all subsequent region launches.
• Operations: Served as Primary oncall for a global identity service spanning 7 production partitions. Resolved 1,453 tickets (241 high-severity), audited and corrected deployment safety rules across 64 pipelines, and built automated drift-detection between authoritative databases to catch issues before they page.
• Mentorship: Mentored 3 engineers (intern to mid-level), supported one through promotion. Designed features and led junior engineers through implementation.
