Software Engineer at Google

July 1, 2019 - Present

Led a core rendering pipeline revamp for the Core Viewer (C++, OpenGL), eliminating a tile culling bottleneck and restoring frame rate under high-density spatial loads across three map verticals. Architected a cross‑platform mobile SDK build pipeline (Swift Package Manager for iOS; Android Library packaging) reducing artifact delivery time from 3 days to 4 hours across four targets. Implemented automated performance measurement in CI with 22 regression checkpoints to catch rendering and memory regressions before production. Designed a C++ scene graph to optimize tile hierarchy and draw-call ordering, cutting redundant GPU state changes by 31%. Implemented quad-tree spatial partitioning to accelerate tile visibility queries, reducing lookup times by 44% in dense layers. Built production reliability dashboards tracking frame time, tile latency, and memory pressure across five regions. Developed a concurrency model for network tile requests and GPU tasks to keep the main render thread u

Software Engineer at RetailMeNot, Inc.

June 1, 2018 - July 1, 2019

Built a high-volume C++ data ingestion framework processing 8M+ shopper events per day with sub-200ms latency at peak. Designed a multi-tenant backend with strict data partitioning, eliminating cross-tenant data leakage over a year. Derived audience cohorts from spatial partitioning logic, improving segment refresh throughput by 35%. Refactored query plans and indexing across 18 critical reporting paths, cutting dashboard latency by 52% and reducing on-call escalations. Consolidated advertiser signals into a unified, queryable hub, reducing average lookups from 4s to 600ms. Calibrated a predictive lead prioritization model, boosting pipeline accuracy by 29% across three verticals. Implemented granular access governance across 12 permission tiers, achieving audit compliance across two consecutive security reviews.

December 1, 2015 - May 1, 2018

Delivered a HIPAA-compliant patient data management platform spanning 300+ practices within a 14‑month cycle. Rewired a FHIR-based distributed ingestion pipeline across eight systems, reducing reconciliation errors by 41%. Built a 360-degree patient intelligence record, cutting report generation time from 6 hours to 45 minutes for 200+ admins. Implemented HIPAA-compliant access governance across five data tiers, passing three audits with zero critical findings. Rearchitected EHR query plans and indexing across 25 high-frequency paths, reducing average query time by 48% and maintaining SLAs during peak cycles. Deployed a predictive billing risk model integrated with MyChart SDK, reducing claim rejections by 33% across 120 accounts. Transformed patient signals into population health segments covering 14 cohorts and automated cross-functional pipelines, saving 400+ hours of manual reporting per quarter.

Software Developer at General Motors

June 1, 2014 - December 1, 2015

Rolled out a connected vehicle SaaS platform spanning dealer relationship management, telematics-driven inventory tracking, and fleet analytics for 2M+ registered vehicles. Rebuilt telemetry ingestion to normalize 5M+ daily payloads, achieving a 99.7% ingestion success rate over a year. Translated driver behavior logs into structured customer intelligence across 18 dimensions, powering targeted campaigns that improved conquest conversions by 22%. Redesigned query execution, indexing, and caching for 30 SaaS dashboards, keeping load times under 2 seconds during peak releases across three model cycles.
