Engineering Intern @ Google From June 2005 to August 2005 (3 months) Research Intern @ Microsoft Research on theoretical topics (lower bounds for locale decidable codes, differential privacy for real-valued queries). From July 2010 to September 2010 (3 months) Engineering Intern @ Google Implemented distributed graph algorithms to benchmark Pregel (a new parallel processing system built to succeed MapReduce). From July 2008 to September 2008 (3 months) Director Of Engineering @ ASAPP ASAPP's mission is delivering automation and work simplification to solve complex problems in the enterprise. I am responsible for the Foundations Engineering team, which encompasses SRE, application frameworks, data engineering and solutions architecture.- Founded the team and grew it to 20 engineers (out of ~100 engineers total). Recruited a diverse and talented group of engineers across across NYC, SF and Buenos Aires.- Mentored and grew individual contributors and managers through 1:1s, architecture and code reviews, and continuous feedback.- Responsible for evolution of overall system architecture. Created and maintained architecture diagram, presented to internal and external stakeholders.- Held primary responsibility for overall delivery to one of ASAPP's earliest enterprise clients.- Introduced or promoted key technologies used at ASAPP, including Kubernetes, Go unit testing, TypeScript, and Jest. From December 2016 to January 2020 (3 years 2 months) Senior Engineering Manager / Staff Engineer @ Palantir Technologies My official title was "Development Team Lead" but my responsibilities included what are typical for technical fellows at other engineering-focused organizations.- Technical mentorship and guidance across the organization. Organized engineering reviews and provided architectural feedback to teams embarking on significant project, especially concerning performance at scale and API design.- Co-owned backend for financial analysis product. Built and delivered multi-user scale and isolation subsystem (comparable to Chrome's process-per-tab). Prototyped shared-memory caching layer for fast restarts. (Spring Framework, Zookeeper)- Drove Palantir-wide transition from proprietary OSGi-like stack to Dropwizard-based microservices. Worked with multiple teams to analyze costs and benefits. Built shared tooling and standards for microservices.- Drove adoption of Apache Spark at Palantir. Designed data-processing DSL and job-orchestration framework (comparable to Airflow). Built infrastructure to help data scientists deploy Python applications and notebooks while respecting Palantir's stringent network and data security requirements. Led development of a full-stack signals intelligence / top-down analysis product built on Spark / Vertica / Dropwizard / AngularJS. Contributed to Spark core and PySpark.- Led a major re-architecture of the authentication microservice used across all Palantir products. Enabled customer-facing teams to integrate with SSO systems faster.- Built continuous deployment and centralized logging across Palantir's cloud-based products. Extended ELK stack and existing cloud deployment products to allow a central dev/ops team to monitor and manage a large number of customer-specific environments without leaking any sensitive information. (This work was still in progress when I left.)- Managed teams of 3-7 engineers. Responsible for career growth, technical mentorship, feedback and performance review. Hiring manager for a team of ~40 engineers. From June 2011 to December 2016 (5 years 7 months) Chief Technology Officer @ TetraScience From January 2020 to November 2020 (11 months) Boston, MA, United States
