Designed app (Node, Postgres, Express, React) allowing internal users to collect music royalties from dozens of sources (including S3 and SFTP), divide royalties among according to user-defined rules, pay out royalties (Stripe), and generate financial reports. Led team in implementing this app, including user interviews, tests (Ava), deployment (Heroku, AWS), and iterating to add features and scalability.

Rebuilt failing ETL pipelines (Node, Postgres, Snowflake) for revenue-critical data, increasing throughput via Node streams and achieving exactly-once ingestion via transactional locking.

Organized, quantified, and prioritized short- and long-term technical objectives for the engineering team.

Wrote infrastructure provisioning code (Node) to enable horizontal scalability of primary infrastructure by sharding databases (AWS RDS Postgres) and implementing a standalone PgBouncer cluster to pool connections between an application cluster and database cluster.

Implemented type safety in company’s Node-based proprietary no-code programming language for speed and correctness.

Pioneered a new caching system (Node, JS) for versioned data chunks in company’s no-code app editor.

Designed and implemented IoT app (Node, Express, Typescript) for remote control and monitoring of company's field units, including continuous collection of time-series data (GCP Postgres).

Built tests (Node, Mocha) using Docker Compose to simulate field units on the local network, validating the app’s throughput and data integrity even under conditions such as high load and intermittent connection.

Led creation of infrastructure for company's core user-facing software, using Terraform to provision Kubernetes/GKE clusters in parallel production and staging environments on GCP.

Established Docker-based development processes and CircleCI pipelines for CI/CD.
