## Work Experience
### Software Engineer @ Meta
Jan 2023 – Present | New York, New York, United States
Leading the Wearable Production Foundation FX Telemetry team at Reality Labs to architect high-fidelity telemetry systems. I ensure that Tier 1 metrics across all wearable devices are precise and trustworthy, providing the critical data foundation needed to ship world-class wearable devices.

### Software Engineer @ Instagram
Jan 2018 – Jan 2023 | New York
As Tech Lead for Instagram Reliability, I set the gold standard for iOS stability for a global community of daily 600M+ users. I specialize in tackling the most elusive mobile challenges—specifically Main Thread Stalls and Out-of-Memory (OOM) crashes—at a scale where every millisecond matters. I believe reliability is the ultimate foundation of user trust; my mission is to build the observability frameworks and lead the cross-functional initiatives that catch complex regressions before they ever reach a user's device.
