— OnRobot

• Pushes system intelligence from Cloud to robots, improving performance by 88%, robustness in choppy Wi-Fi network, and horizontal scaling

• Serve as Tech Lead, leading Sprint meetings, planning, cross functional team coordination (Quality, FE, Robotics), and Product alignment

— Web Code Editor

• Initiate and build the full stack for a web-based code editor to script and debug workflows executed by our robots with console logging and stepping

• Bolsters script development for time-critical pilots with IDE QOL features and serves as a great platform to dogfood product-essential API

• Leverages Monaco Web Editor & React for UI, a language server, and dedicated execution microservice with debug hooks to contain side-effects

— Jaeger Tracing

• Trace our go codebase with Jaeger and decorators, an internal tool cutting time in half to root cause bugs and isolate performance bottlenecks

• Promote with guides and workshops and gain traction in usage such that Support, QA, etc. provide trace details in JIRA tickets

— Workflow Execution Engine

• Implement critical subsystems like an event-driven execution pipeline with priority, RRule-based Scheduler, and a Lua VM for product velocity

• Assist Support and Field Application Engineers by discerning if it is customer or system error and squashing 50+ JIRA production tickets in a year

— Streams Node (Robot Sensors Streaming)

• Migrate from python to go for robot sensors streaming using ros-go, reducing thread crashes and CPU usage from 20% to 3%

• Convert from JSON to protobuf messaging which lowered data footprint by 33% and increased serialization speed 5-fold

— TagSurveyor (RFID Robot Solution)

• Architect using dual Postgres & noSQL Cassandra to process 100K RFID data, track data changes, and store 5-tiered clustering

• Pioneer OpenAPI documentation to establish contract early on, enabling parallel development of FrontEnd and BackEnd

Power Modeling and Calculator

• -----------------------------------------

• Redesign calculation to using a tree of equations, reducing 40k+ hardcoded lines to 5k

data-driven from source files

• Utilizes pattern matching and recursion for mathematical expression evaluator to handle nested

parentheses, ordering, etc.

• Requires back-and-forth communication with Power GUI team in Shanghai on database API and

enhancing user experience

Device Model & Capture

• -------------------------------

• Interact weekly with Silicon team to ensure SW data abstraction and modeling are consistently

aligned with HW

• Team alongside entry engineers on rolling out data-driven, single source XMLs that share chip

info across functional teams

• Improve operating efficiency of job functions using Python such as automating 20-hr of

AutoCAD to 30-min of coding

Software Development Kit

• ----------------------------------

• Implemented a full-stack SDK from Android to Linux C driver to enable greater SW access of our

HW-centric products

• Stabilized performance (pedometer & tap) by handling concurrency issues with locks in Linux    interrupt routines

• Assembled kit with demos and docs to market solution to sales team and trained Shanghai

engineers on site for product support

Ultra Low-Density Platform

• -----------------------------------

• Tested the framework that enabled quick bring-up of RTL system designs in pre & post

silicon setting

• Validated RGB & Infrared SPI-host system design using platform which reduced operating times

by 50% (1 month vs 2 weeks)

• Presented and successfully demoed the platform to R&D senior leaders and gained approval

for the initiative
