- Built network and application infrastructure to connect a heterogeneous set of partners/customers to Hiya's standardized call handling tooling - Built prototype SIP(core telephony protocol) application to further enable customer connectivity - Built honeypot to capture and record spam calls for hundreds of thousands of numbers - Extended credential management API to enable customers to self service technical set up

ATROPS - Adaptive TRansportation OPtimization Service - Jan 2019 - Aug 2020- Designed and built API to search for transportation capabilities by delivery speed.- Managed fleet scaling for a service that serves millions of TPS using tens of thousands of servers- Reduced operational expenses by thousands of servers by optimizing inefficient service callsAWS Networking - Internet Monitoring - Sept 2014 - Jun 2017 - Lead a team to maintain and evolve an internal internet monitoring product including seekingcustomer/stakeholder feedback and designing roadmap.- Collaborated in design and implementation for a system to shift traffic off failing Internet ServiceProviders.- Analyzed internet measurements to understand key performance characteristics controlling when to shift off a provider.- Designed and lead implementation of a world wide data pipeline to collect measurement data and store for analysis.- Developed software control plane for orchestrating probing software and route management.Supply Chain Optimization: Inventory Planning and Control May 2011 - Sept 2014 - Designed and implemented a pattern for asynchronous dependency calls. This pattern decoupled latency from throughput and allowed components to scale independently in a distributed system. - Rearchitected simulation tool to distribute order simulations across the production ordering fleet using idle production capacity. This reduced simulation runtime by up to 90%. - Changed core inventory buying algorithm to dynamically select the best vendor based on based onlocation. - Parallelized dependency data fetches to optimize system throughput - Refactored core inventory buying code to individual services and libraries. - Revamped work scheduling software in distributed system to distribute system load over time whilerespecting business work priorities. - Designed and implemented parallel idempotent inventory ordering module. The previous module cutduplicate orders during failure.
