I keep 1000+ active developers and 2000+ commits/week running smoothly in our Continuous Integration infrastructure. This is done by mentoring new and senior team members, and creating new tools and processes focused on efficiency and reliability.Leadership (community building, team leader, cross team collaboration):* Collaborate with developers and managers to identify more efficient ways to get test results, regressions, and tooling changes.* Project lead on 3-4 projects at a time, helping engineers increase responsibility and impact.* Leader of community participation within Mozilla. Mentored in Outreachy, GSoC, UCOSP, and volunteers.Continuous Integration Efficiency (test relevancy, duplication, faster turnaround):* Created SETA (Search for Extraneous Test Automation) to identify tests which do not find regressions and run them less, reducing machine use and expenses by up to 70%.* Regularly analyze runtimes and configurations to look for tests that are accidentally disabled, and for failure patterns where attention is needed.Intermittent Test Failures (>1M tests/commit, dashboards, tools, process):* Reduced failure rate by 75% in 6 months and created tools and policy to be part of developer workflow.* Ensured all tests have an identified triage owner, and optimized the triage process across all Firefox teams, resulting in >1000 old bugs fixed.* Built automated tools to identify poorly written tests and integrated into developer workflows.Other:* Refactored test harnesses to support running on physical phones (Nokia Maemo, Windows Mobile, Android), Android emulators, AWS, and Docker.* Created an alert dashboard to highlight performance regressions, reducing developer randomization, resolving 98% of regressions.* Increased performance coverage by adding new benchmarks, operating systems, hardware configurations, and cross browser comparison.Technologies: Python, Javascript, SQL, Linux, Windows, bash, Docker, AWS.

Tasks included: owning two year roadmap and plan for testing efforts, writing test plans, collaboration with partner teams, projecting lab budget, defining product goals, interviewing and managing contractors / junior team members, and developing test automation tools. Migrated group wide test harness and OS deployment solutions for six groups (140 employees). Technologies Used: C++, SQL, TCP/IP, firewalls, C#, shell scripting

Us

Organized and allocated projects for the test team, reviewed checkins, created test plans for new and existing features, automated web based applications, tested and signed off on release milestones and customer specific releases, and maintained test tools. Technologies Used: Java, SQL, ASP, JScript, .NET, J#, C++, search engines

Developed test tools: BVTs, attack tools (traffic generation and reorganizing packets), and performance monitoring tools. Led test team, provided sign off criteria and verification for multiple releases. Set up and configured test networks (routers, switches, VPNs).Technologies Used: TCL, C++, shell scripting, Linux, routers, switches, SQL

Developed and modified device drivers for WinCE, Win98, and WinNT. Adapted and extended the WinCE kernel to custom motherboards. Customized devices and integrated third party software for trade shows and demos. Created control panel applets and custom applications ranging from touch screen keyboards to web browsers.

Renton, Wa, Us
