Work Experience

Founding Engineer

Develo | Sept 2022 - Present

As the first full time employee, I witnessed the very first commit to Develo’s git repo. I work closely with the CTO, CEO, designers and other engineers to develop a modern EMR for pediatrics.

  • Using Redwood.js to develop full-stack product features
  • Leveraged BullMQ and Redis to enable asynchronous job processing
  • Designing information architecture
  • Led integration of third party solutions such as e-prescribe, e-lab, and e-fax

Senior Software Developer / Technical Lead

ixlayer | Sept 2020 - June 2022

As the second full time backend developer, I established a collaborative remote team culture grounded in written communication: detailed code review, clear concise unit tested code, and technical doucumentation. During my time at ixlayer, we raised an extremely successful Series A and grew by an order of magnitude. I rose to tech lead on the “core” backend team, mentoring junior developers, establishing team standards for code, overhauling our information architecture, and working cross-functionally with product managers and frontend developers to propose solutions to customer problems.

  • Aligned data model with industry-standard FHIR specification
  • Implemented lab result interpretation engine
  • Integrated third party API’s (payment providers, labs, doctor networks, etc.)
  • Maintained and augmented internal and external REST APIs
  • Established a collaborative and quality-focused team culture

Senior Software Developer

OrbitalRX | Sept 2019 - Sept 2020

As the primary application developer on a technical team of four, I had a high degree of ownership of technical decisions on both the backend and frontend. Collaborating with the CTO and product designer, I wrote API’s and frontend components to enable new features. I aggressively paid down technical debt by writing unit tests, refactoring large frontend components, and significantly simplifying the backend.

  • Re-architected backend. Consolidated two servers (Apollo Server and Django REST) into one GraphQL server written in Go using gqlgen
  • Improved readability and maintainability of the frontend using React hooks, testing (react testing library, cypress), and documentation (react-styleguidist)
  • Mentored a junior frontend developer (recent code bootcamp grad)

Software Developer

SolarWinds | July 2018 - Sept 2019

Working as part of a multi-national team, I enabled user registration for and configuration of Solarwinds Threat Monitor product (acquired from Trusted Metrics).

  • Created a user registration server using Python’s Connexion library
  • Collaborated with a multi-national team of developers

Python Developer

Trusted Metrics | Dec 2017 - July 2018

As the Python developer at a company of 8 employees, I leveraged an open source project to implement the next generation alerting engine for our flagship product. My efforts contributed to a successful acquisition by SolarWinds.

  • Implemented next generation alerting engine for Trusted Metrics’ flagship product

Software Developer

Czitek | April 2016 - Nov 2017

Recruited away from Agilent, I joined Czitek, a small start-up developing FTIR (Fourier Transform Infrared) spectrometer products. I developed software to support engineering, manufacturing and use of FTIR spectrometers. Additionally, I contributed in a scientific capacity: troubleshooting prototypes, running experiments, and implementing algorithms.

  • Implemented an FTIR and signal processing algorithm suite
  • Used MvvmCross and C# to create the UI for the ThreatID spectrometer
  • Developed an internal website tracking prototype metrics using Django

Hardware Engineer

Agilent | June 2014 - April 2016

As an optical/mechanical engineer, I developed FTIR spectrometer products.

  • Used AutoDesk Inventor and Zemax to design optical parts.
  • Used Python to process raw data from prototype instruments.
