Creator

• Full-stack Django REST server with PostgreSQL, Vuetify frontend, and a multiproccessing backend. Docker and native deployment.
• Active user community with 303 GitHub stars.

Sr. Software Engineering Manager

• Scaled the Map Engineering Group from 2 to 24 engineers across 4 teams, hired 22 engineers and promoted 4 ICs to engineering managers.
• Owned the technical roadmap and delivery for the AV map cloud build pipeline and map API, serving both on-vehicle development and simulation — critical path infrastructure for Cruise's expansion from a single SF neighborhood to three cities.
• Led design and delivery of a web-based map labeling platform that replaced legacy ArcGIS desktop tools, reducing map labelling area cycle time from hours to minutes, allowing distribution of map labelling to international teams, and removing a single local database.
• Established operational cadence for the group: sprint management, quarterly OKR planning (via Jira Structure), and cross-functional coordination with Perception, Planning, and Ops teams.
• Mentored engineers through career growth from mid-level IC to senior IC and into management, building a sustainable leadership pipeline within the group.

Sr. Software Engineer

• Increased HD map production frequency from annual releases covering one neighborhood to twice-weekly releases across three cities.
• Designed and built the AV map build pipeline (C++, Python) and contributed to on-vehicle AV software in C++.

Director of Engineering

• Built and managed a 20-person engineering organization (ICs and managers), including hiring, performance management, and coordination with remote teams in Russia and Eastern Europe.
• Led the ground-up rebuild of the Sidecar Delivery backend (Python Pyramid, SQLAlchemy), shipping the platform that powered the company's strategic pivot to delivery.
• Rewrote the Node.js rideshare dispatch server, resolving chronic reliability issues and improving platform uptime from several hours of daily downtime to 99.5% across twenty US cities.
• Introduced production monitoring and incident response (PagerDuty, Pingdom, CloudWatch), trained the team on 24/7 on-call operations, and established the company's first SLA-driven uptime culture.
• Scaled backend infrastructure to support multi-city operations: sharded MySQL databases, introduced horizontally scalable worker/queue architecture, and managed AWS clusters with Docker and SaltStack.
• Drove engineering quality practices: established integration and unit testing standards that measurably reduced bug severity and production incident frequency.

Software Architect and Team Lead

• Managed a 4-person development team building Birthday Alarm, a consumer web application.
• Architected and built shared Python Tornado infrastructure, MVC framework, Cassandra storage cluster, and Facebook OAuth 2.0 authentication used across all Monkey Inferno projects.

Sr. Software and DevOps Engineer

• Co-designed and built a 40TB custom distributed file system in C/C++ (predating Hadoop), serving as the backbone of Bloglines' content storage.
• Built a 20-node MySQL Cluster for real-time user state management and implemented Berkeley DB replication with automatic failover for Bloglines databases.
• Planned and executed a full data center migration (40TB, 250 machines) with zero downtime.
• On-call 24/7 for a 250-machine production cluster; coordinated operations with a geographically distributed team (US and China).

Software and DevOps Engineer

• At Aldon, Pitney Bowes, BARCO Graphics, and The MITRE Corporation
• Enterprise software, defense systems, and graphics/imaging toolchains
