Hi! I'm a software engineer currently located in San Diego (moving to the Bay
By trade, I work on applications that deal with a lot of data; by vocation I
study mathematics and philosophy. I have experience in application architecture,
databases, and other data-heavy systems.
** Hero Projects, Lead Project Engineer
2018 - present
Hero is a media company in L.A. On a part-time basis, I'm developing their
mobile and web apps, which is like Netflix for comic books. Instead of movies
there is a comic book player, which overlays music according to the page of the
comic you're on and guides you through the story. This is alpha stage currently,
but will go live later in 2019. Written in all Haskell using [[https://haskell-miso.org/][Miso]].
- Haskell (frontend and backend)
- REST API
- PostgreSQL database
** UE Authority, Senior Software Engineer
2018 - 2019
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.
- AWS infrastructure
- Haskell data pipeline backend
- MySQL and AWS Redshift
- RESTful API with Swagger docs
** Software Engineer, Liaison Technologies
2015 - 2018
I co-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 is 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.
- Clojure and Java
- PostgreSQL, ElasticSearch, ArangoDB
- Apache Kafka, Apache HBase
- REST API with Swagger integration
- event sourcing, command query responsibility segregation (CQRS)
- schema matching
** Software Engineer, Thermo Fisher
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
- Typescript & AngularJS UI
- Python backend
- CouchDB datastore
** Software Engineer, WholeLatteLove.com
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 Ruby on 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
- Created a suite of simulation tests for our legacy order processing systems
using the Clojure framework Simulant.

** Lead Developer, Nebula Bio
2014 - 2016
With a biomedical engineer partner, I developed an open source, low cost,
portable blood analysis platform. Our goal was to be the “Arduino of biotech.”
All development was done on GitHub. Unfortunately the project was cut short
because protein reagents are expensive and I was a broke college student.
- Designed a POSIX-compatible driver for a custom potentiostat.
- Created a custom crowdfunding webapp with a REST API in Clojure,
deployed on Heroku.
- Created a GUI in Python for the driver, and beginning beta testing
- Lead and handle all project management and financial aspects of the
** Instructor, Thinkful
2014 - 2015
Taught data science and full-stack web development with Python to new and
intermediate students. I also helped develop their curriculum by writing
tutorials and exercises for each of the courses I taught.
** Nebula Sports
2012 - 2013
An RIT-sponsored startup project that lasted for about a year, in which we
developed novel headgear padding for athletes. My main role was in guiding the
scientific research, while solely managing the fundraising (grants and private
investment). In a 4-person team, we developed an algorithm for optimizing our
custom padding to a specific position within a specific sport. Patent concerns
made us shut down this part of the project. We then prototyped and programmed an
accelerometer to be housed inside a helmet and signal to the athlete the
severity of an impact. Reebok released their CheckLight product before we
finished developing, and so scooped the market. All algorithm programming was
done in Matlab.
** Freelance Developer
2012 - 2014
As a freelance developer, I created two ecommerce systems in PHP, a
ClojureScript front-end website to be used as a landing page, and worked on an
e-magazine site for a local Rochester magazine.
