I focus on solving scalability problems in our data and backend systems by designing and upgrading modules to handle our rapidly growing user base. I also support the democratization of data across the company by building the pipeline and warehouse infrastructure that transports and stores our data before it is consumed by internal consumers at all levels and used in external reports, releases and products.In addition, I support incident response efforts, both with direct engineering fixes and through rapid data analysis to understand problems as they develop and to inform solutions.

Backend Development: Switched payment processors without downtime while handling tens of millions of dollars per month. Created a distributed auto-notification system which serves tens of thousands of users daily.Reliability and Scaling Improvements: Re-architected ETL pipeline to reduce dropped event count from 50,000+ a month to zero. Built API that increased batch operation dispatch capability from 40,000 to 3,000,000 jobs across all systems while reducing coupling and increasing fault tolerance. Reduced total cloud costs by over 30% and reduced average monthly backend open bug count by over 60%.Data Operations: Built company-wide Python data analysis and forensic accounting toolkit and ran all data analyses for $12M funding round. Sped up mission-critical data export by over 99%. Created self-serve terminal for non-technical employees to run complex data operations, reducing turnaround time by over 90%.

Expanded and reactored a serverless Node.js GCP backend serving iOS, Android, and web. Reduced calculation requirements in the backend’s highest traffic system by more than 97%. Transitioned half a dozen live user-facing systems from Firestore to Realtime Database with no downtime. Lead transition from legacy development workflow to a DevOps based monorepo branching model.Built decentralized relational cross database social network utilizing Cloud Tasks, PubSub and Firestore. Created business-facing data marts that reduced skilled, manual, mission-critical workload by 75%. Improved engagement with critical coaching feature by more than 20%.Created ad-hoc Python and Jupyter notebook analyses for both business and data science teams. Built data pipelines informing live recommendation and coaching systems and internal tools to monitor user-base health.

Studied high-dimension complex analytic singularities using Python, Sage MATH and Singular, leveraged operator-controlled Mersenne twister generation via a multistage stochastic Markov chain process.Discovered infinite family of polynomials with negative Lê cycles, created the first algorithm capable of finding beta invariants. Decreased solve time in 3 - 5 dimensions by several orders of magnitude.Parallelized algorithm using both a Bash script and a GNU parallel implementation. Increased local polynomial sampling size by more than 10000x, allowing for more sophisticated analysis at scale. Deployed algorithm remotely via a Slurm job array on a centOS supercomputing cluster allowing for billion point sampling and statistical investigation.
