Software Engineer (Intern) @ TeleCommunication Systems, Inc. From May 2007 to August 2007 (4 months) Oakland, CACo-founder, CTO @ Doorstead Doorstead is a technology-operations company. We are a full-service property management brokerage that provides cash-flow certainty to rental property owners. Traditionally, property managers (NPS 8) overpromise on rent to sign owners, creating months of vacancy and lost income. By collecting precise data during inspections and leveraging historical rental data, we are able to provide an unconditional rental guarantee to owners (ex. $3,500/mo starting in 28 days).[more to follow later - engineering / technology / data; cross-functional generalist] San Francisco, CAInvestor @ Inside.com Top industry & world news Senior Software Engineer @ LinkedIn • Created pipelined webpage technology in combination with a modern JVM JavaScript engine to decentralize JavaScript webpage template processing and improve user-perceived page load time• Early member in the effort to integrate the Typesafe Play! web framework into the internal web application ecosystem as a more robust and developer-friendly alternative to a similar legacy in-house framework, playing a wide range of roles in this startup-like team during the maturation process• Seminal architectural development to overhaul company-wide static content distribution methodology towards a more robust and streamlined system that can be scaled to multiple separate datacenters• Developed a "news feed as a service" platform that can be deployed and customized in a variety of contexts with relatively little proprietary configuration, most notably devising an algorithm heavily leveraging Scala’s functional programming capabilities to implement a domain-specific language of customizably complex aggregation rules for news feed items culled from various different sources• Enhanced and scaled a content decoration pipeline built on Apache Kafka capable of joining entity information to raw data for displaying in the legacy news feed, and later migrated the the new news feed platform service to consume this data under an improved entry representation paradigm From April 2011 to July 2015 (4 years 4 months) Mountain View, CASoftware Engineer @ TeleCommunication Systems, Inc. Significant overhaul of an inefficient system to enable human operators to merge NAVTEQ and TeleAtlas map data at scale. Early work on a system to intelligently detect deviations of in-transit vehicles from their intended routes.This is not my patent, but I essentially overhauled it to yet another level by enabling the merging to happen on a finer granularity level than what was patented, thereby considerably improving the productivity levels of the tooling operators and quality checkers by being able to focus and iterate on smaller chunks of work at a time: https://patents.google.com/patent/US6564224B1 From August 2008 to March 2011 (2 years 8 months) Oakland, CAAssistant Programmer/Analyst @ California Partners for Advanced Transit and Highways (PATH) From June 2006 to August 2006 (3 months) Richmond, CASoftware Engineer || Engineering Lead @ DoorDash Narrative: bit.ly/bliang-doordash-interviewTechnical:• Integrated Apache Airflow into v0 data warehousing system in order to improve ETL job tracking and dependency management. Together with production troubleshooting, maintained 99% SLA on daily ETL runs.• Redesigned and drove rollout of the experimentation / tracking infrastructure leveraging open source technologies to improve data integrity, logging, correctness, and ease of operation.• Upleveled an entire backend engineering team of ~5 through technical roadmapping, regular technical group discussions, mentoring and developing multiple engineers, and direct technical contributions. Solved numerous critical performance issues and made significant performance improvements in the Scala/JVM-based stack.• Member of "architecture group" of senior engineers responsible for making key technical decisions, vision-setting, and guiding execution for the entire engineering team. Bridging the gap between product and infrastructure.• Pioneered the transition towards a proper cloud-native microservice infrastructure on Kubernetes/Helm/Draft/Jenkins/etc, conducting extensive research & development and proactively networking with industry leaders in the space to accelerate the team's rate of learning. Supported onboarding of 30+ microservices onto internal platform from legacy PaaS.• Pivoted to developer experience in general to balance tooling investments in both microservices and the existing monolith, leveraging efforts of ~5 team members.Organizational:• Revamped key parts of the backend engineer pipeline to be properly seniority-aware, and provided effective guidance to the technical recruiting team on operations of nearly every hiring funnel outside frontend/mobile.• Initiated organizational optimizations for overall engineering team efficiency, thereby getting more output from the same people while unofficially investing in and enhancing other colleagues' professional trajectories even outside of own team. From July 2015 to July 2019 (4 years 1 month) San Francisco, CA
