Working on distributed systems features in the highly concurrent C++ codebase of the core MongoDB server. Particular focus areas include sharding, fault tolerance, cluster management, and distributed algorithm implementation.

Research focused on high-performance distributed systems, distributed databases, consensus protocols, and concurrency control.Contributed to a custom research platform to study distributed database transactions. Worked on a concurrency control algorithm that uses distributed dependency tracking to order commits.Worked on the prototype of a distributed database built on top of infiniband providing low latency and high throughput data access and retrieval.Modified the etcd distributed key/value store to implement optimizations of the raft algorithm.

Demonstrated how to collect data from existing distributed systems to generate a reinforcement learning model and accurately estimate the policy’s performance without the risk or cost of deploying it on live traffic.Modified the Redis key/value store to incorporate our trained model to make cache eviction decisions.This work was published in the HotNets 2017 conference.

Worked as part of the platform services team where I have played a critical role in increasing the fault tolerance and availability of several key backend systems which support Blurb’s global retail business.

Provided custom mobile and web application development servicesCloud automation and configuration.Custom software development.

Provided technical advice and services to a diverse group of clients in the telecommunications, retail, technology, energy, advertising, insurance, and non-profit sectorsProvided Software scalability and architecture guidance.Developed distributed applications using a wide variety of technologies: Python, Ruby, Java, C#, C++, Javascript.Automated testing strategy and implementation.Trained teams in adopting agile software delivery practices such as continuous integration, automated deployments, and test driven development.

- Provided technical services to government agencies such as The State Department and The Department of Defense.

- Implemented Automated Proof of Claim System (APOC) for the IRS. This system assists the IRS in obtaining tax revenues from insolvent taxpayers by integrating with multiple state and federal legacy systems.- APOC has enabled the IRS to identify and reclaim over a half-billion dollars of unpaid tax revenue.
