Faire is an online wholesale marketplace that connects retailers and brands globally, empowering small businesses to compete with major retailers such as Amazon and Walmart. In a dynamic startup environment, my role has evolved significantly, with key achievements including:

• Authored technical vision document for Faire's payment systems. Initiated and drove critical projects, such as extracting a payment service and developing a SQL-based invariant validation system. These systems eliminated payment-related SEVs.
• Served as Senior Engineering Manager and tech lead for the Shipping team, overseeing 8–12 engineers. Developed a long-term technical strategy to optimize shipping costs and improve system stability. Delivered +0.25pp to contribution margin on $2B GMV.
• Led 5 person tiger team to build Volume Pricing (akin to airline loyalty programs) from design to launch in under two months.
• Drove org-wide cultural transformations across 300+ engineers by leading several cross-functional High-Performance Culture working groups, raising engineering standards and execution velocity.

Waymo is an Alphabet company focusing on the development of self-driving technology. I worked on the Fleet Infrastructure team where I was the tech lead for the OpsApp, an internal Android app that is used by 1000+ safety drivers daily. Some highlights include:

• Tech lead of 7 person team, including 3 engineers, a product manager, a product operations specialist, a technical program manager, and a UX designer.
• Received early promotion to Senior Software Engineer within first year of joining.
• Optimized data path from the self-driving car to the phone to achieve sub-300ms latency in support of streaming real-time telemetries to the safety driver.
• Co-authored this patent based on my work designing and building the tool suite that enabled roadside assistance team to navigate to a self-driving car on public roads within minutes of an incident.

gRPC is Google's next-gen RPC system, built from the ground up in open source. gRPC is a highly performant system built around a simple yet powerful wire protocol. The library provides idiomatic APIs in nine supported languages. Through 250+ pull requests, and even more internal changes, I have contributed mainly to gRPC's C core. I have also made significant contributions to the C++ and Python wrapped layers. Some highlights include:

• Created the team's internal benchmarking framework, automatic regression detection system, and performance dashboards.
• Migrated TensorFlow's distributed runtime to use gRPC internally at Google.
• Implemented connection-level monitoring feature for the C++ stack, which exports critical debugging data of live services and presents them in a simple HTML page.
• Co-authored RFC for gRPC client retries in 2017. It is now implemented across all language stacks.
• Created and delivered 40 minute tech talk on gRPC performance at KubeCon.

Full stack internship on the infrastructure team. Key accomplishments include:

• Created multi-tiered tool (frontend UI, service layer, backend task) for Bloomberg developers to aid in the task of debugging and killing haywire processes on production machines.
• Developed a program to track the master logfile on specific production machines and raise alerts and tickets automatically based on previous decisions.
• Won first place in algorithmic coding competition among all of the interns.

Freelance programming work focused on social media data analysis and audience research. Key contributions include:

• Collaborated with team of freelance coders to create several methods of exploiting Twitter data in order to gauge audience interest and find potential markets for celebrity TV channels.
• Designed and developed a program that uses the Twitter API to construct graphs from follower/following relationships, then performs various metrics on the data (PageRank, HITS, etc).

Quality assurance internship at a high-frequency trading firm in Chicago. Key accomplishments include:

• Developed an automated testing wrapper to validate company software responsible for sending orders to the BATS exchange.
• Planned and executed comprehensive set of manual tests on a program providing a live market feed from the exchange.
