Work Experience
Software Developer
Freelance
- Developed a service (TypeScript, Flask, and Hasura) while contributing as a lead and overseeing other developers (three developers).
- Designed and implemented a service to handle reproducible scientific workflows; leveraged AWS container service and versioned files in S3.
- Built a service for a medical marijuana startup; also designed a multi-state site, processed payment, and handled appointments and sensitive documents within HIPAA constraints.
- Developed a UI for a ticket sales startup; connected to Auth0 and processed payments via Stripe.
Software Developer
CyVerse
- Solved a large performance issue in our Django search API by submitting a fix to a popular open-source library, Django REST Framework.
- Created the front-end code responsible for complex flows like launching virtual machines; designed the process for caching front-end data.
- Managed code releases (tagging and merging of features and hot-fixes) for a team of four with Git.
- Developed a tool to deploy the service on a Linux server or virtual machine. It was used by the team to have a consistent development environment.
Experience
Spling Co-founder
https://www.spl.ingKey technical challenges for this service include robustly extracting HTML from a website, identifying grammar mistakes in the text, handling false positives, and creating an efficient UI for selecting pages to spell check and processing many website pages in parallel.
PDF Compression Figma Plugin
https://www.figma.com/community/plugin/1217632496996584187/compressed-pdf-and-image-exporter-pdf-png-jpg-webpThe plugin has been used by 86,000 users and has about $1.5K MRR.
Convergence Platform
The platform allowed conforming docker images to be connected into pipelines. These pipelines were then versioned and could be passed files as inputs to produce outputs.
This service was implemented using a TypeScript front end, which subscribed to data changes via GraphQL. The back end for analyses was a Flask API, which launched docker containers in AWS ECS and managed files via AWS S3.
Programmatic Ad Targeting Platform
https://www.healiolytics.com/After working with this client to develop the first iteration of this project, I was hired to implement the customer-facing version. I worked with a design team and managed three other developers to complete this project. I also developed a docker-based development environment and hosted the service in AWS. I then used Terraform to manage a staging and production environment in AWS.
