Staff Product Software Engineer with 10+ years of experience building and scaling data heavy products across industries. Specializing in developer tooling, DevOps, AI workflows, and delivering zero-to-one solutions for new customers.

## Work Experience
### Staff Engineer @ Parasail
Jan 2025 – Present

### Staff Engineer @ Groq
Jan 2021 – Jan 2024
• Managed internal services, build tooling, and DevOps processes.
• Developed hardware-in-the-loop testing to ensure hardware reliability.
• Contributed to the high-level ML library for advanced machine learning workflows.
• Developed internal and external documentation systems to support team members and customers.

### Infrastructure/Software Engineer @ Groq
Jan 2019 – Jan 2021 | Mountain View, California, United States

### Project Lead Developer @ HERØ Projects
Jan 2018 – Jan 2019
• Developed mobile and web applications for Hero, a media company in L.A., delivering a "Netflix for comic books" experience.
• Designed and implemented a comic book player that overlays music based on the page, enhancing the storytelling experience.

### Senior Software Engineer @ UE.co
Jan 2018 – Jan 2019 | Greater San Diego Area
UE.co provides car- and home-insurance sales leads to a country-wide network of salespeople. I was responsible for developing a few data pipelines for use in their next-gen platform. The service would fetch leads from external providers or accept a CSV upload of lead data, scrub the data through half-a-dozen internal services, and deliver the end result to a front-end application which allowed the salesperson to save the list of leads for later. My services were written in Haskell and designed to be highly concurrent, handling something like 60k-70k leads per minute. The bottlenecks ended up being the insert operation into Amazon Redshift, and the third-party APIs.

### Software Engineer @ Liaison Technologies
Jan 2015 – Jan 2018 | Remote
I designed and implemented a distributed, streaming, immutable, event-sourced cloud database for semi-structured enterprise data, plus a few AI-based microservices for extracting structured intel out of the semi-structured streams of data in our database. The business goal was to flexibly extract intelligible data from customers’ data banks. Everything was done in Clojure, on a private cloud infrastructure with Docker containers as deployable microservices.

### Software Engineer @ Thermo Fisher Scientific
Jan 2017 – Jan 2017 | Greater San Diego Area
I wrote services and UIs for creating and running hardware tests on all of Thermo Fisher’s equipment. The application allowed field technicians to collaborate on custom diagnostic tests for each instrument, connect to any instrument on the network, run tests remotely or on-site, etc. The end product is deployed as a Docker container onto mostly Windows machines used by Thermo Fisher technicians. Tech stack: Typescript UI, Python backend, CouchDB datastore.

### Software Engineer @ Whole Latte Love
Jan 2015 – Jan 2015 | Rochester, New York Area
As a full-stack developer, I was responsible for the DevOps workflow on AWS and legacy servers, setting up and doing deployments, diagnosing and fixing bugs, managing a git workflow between in-office and remote developers, and coding new features on both the frontend and backend.

- Designed/implemented app-wide notification system.
- Moved a legacy Rails app from a small, unreliable data center to AWS, with continuous integration, testing, & deployment.
- Updated a large Rails ecommerce engine we depend on (Spree) which required implementing a dozen custom extensions.
- Developed a data generator to easily replicate our production environment in staging.
- Created a suite of simulation tests for our legacy order processing systems using the Clojure framework Simulant.
