Recruited to drive strategic technical transformation of core library powering Microsoft Teams with 200+ contributors. Lead engineering productivity strategy across release pipelines, CI reliability, build performance, and test infrastructure.

Engineering Productivity Impact:

• 44% PR cycle time reduction (P50: 52h → 29h), recovering 1,400+ developer-hours/week across 60 weekly PRs
• 58% build time reduction (31 → 13 min) through cross-team compilation cache initiative (70.7% cache hit rate day 1)
• 35–45% delivery throughput increase (~140 → 190–200 deliveries/week), adding ~165 engineering-hours/week
• Flaky-test rate 13.4% → 4.4% through 9-month cross-team program (200+ engineers, zero dedicated headcount)
