Building Infrastructure
at Scale

Staff Software Engineer & Systems Architect

I specialize in Python-powered distributed systems at massive scale — from autonomous driving platforms to real-time location services handling 10M+ QPS. I architect backend infrastructure that bridges sensor data, AI/ML inference, and cloud-native applications. Currently building production mobile apps with Python backends at Neher Data Systems.

Notable Projects

Uber Navigation Platform

Uber · Staff Engineer

Contributed to one of Uber's largest services (~10K nodes per DC) powering all routing and mapping. Reduced p95 off-route detection from 5min to 2min through algorithm improvements and on-device data ingestion.

Java Python GPS/Sensor Fusion Multiprocessing

Location Platform

Uber · Manager/Staff Engineer

Built and led team increasing global GPS+sensor data ingestion from ~80% to 97%+. Architected GDPR-compliant location sharing, enabling RideCheck safety features and crash detection.

Python Cassandra Kafka 2-10M QPS

Python Platform at Uber

Uber · Founding Engineer

Founding member supporting all Python development company-wide. Led Python 2→3 migration covering 90%+ of services. Major contributor to tchannel-python (Tornado-based Thrift RPC).

Python 2→3 Tornado Open Source

HERE Autonomous Driving Fleet

HERE Technologies · Manager/Architect

Led Capture Systems team (2→15 engineers) designing next-gen mapping vehicles. Built lambda architecture for real-time fleet telemetry using Apache Storm, Kafka, and Elasticsearch.

Apache Storm Kafka ROS PostGIS

ShadowMaps

Uber · Staff Engineer

Contributed to multipath-aware GPS correction system accounting for signal reflection in urban canyons. Improved location accuracy for millions of trips.
