I built and managed a team of six software engineers that created data collection systems. KoBold Metals discovers the materials critical for the electric vehicle and renewable energy revolutions by combining the best of geology, machine learning and data engineering. Tech: Postgres | DBT | Jenkins | S3 | Parquet | Python | Django

I built a remote team of four senior software and machine learning engineers who developed automated-budgeting, forecasting, transaction insights and fraud systems for Digits's neobank offering. We did end-to-end ML: building data pipelines, training models and deploying to production.We deployed a dozen new algorithms and machine learning models and decreased model deployment time from two weeks to a few hours using Kserve.Tech: Sklearn | Gensim | Kubernetes | Kserve | MLFlow | DeltaLake | Spark | Databricks | DBT | Protobuf | Javascript | Typescript

I managed a team of three software engineers, four data scientists, two interns and a project manager who developed machine learning, fraud and underwriting systems.We served millions of customers and I led a migration to AWS Sagemaker which brought our ML model build and launch time down from three weeks to three days.Tech: Keras (Tensorflow) | Sklearn | XGBoost | Sagemaker | S3 | DynamoDB | Kubernetes

I built and deployed ML models for fraud and underwriting.I led a team of five to launch a machine learning feature store and compute service which fixed feature consistency issues and allowed us build 10x new features.Tech: Flask | Docker | DynamoDB | Pandas | Python | Sklearn | Xgboost | AWS Elastic Container Service | AWS S3 | ASW Lambda | Postgres | Ruby on Rails

I worked at Nest Labs which was owned by Google.I served as an engineer on a new product team working on algorithm design, validation and implementation for embedded devices.I designed and implemented new computation architecture for embedded device sensor-fusion algorithms which enabled the development of a dozen new real-time on-device sensor algorithms.

I worked on Firefox OS for mobile devices in Javascript and C++.

I wrote a reversed battery detection module in C for window shade products.

I created a force sensor device to measure forces at a fracture site in a loose cast and developed prototype devices to improve arm mobility for premature babies.
