Delon R. Newman—Software, Training and Design

Consulting Software Engineer  · Remote · 3/2021 - Present

Consulting as a software engineer. Mentoring programmers at all levels of experience. Volunteer time each week toward building systems to assist with coordinating community outreach. Also volunteer on open source projects.

  • While helping a team with their React based frontend (without any experience with React) created a custom calendar component that fit their needs after recognizing that the off-the-shelf open source options wouldn’t work for them. Was able to deliver this component ahead of schedule with test coverage and with an array of date utilities that came to be adopted by the team throughout the rest of the code base.

  • An organization’s management was considering rewriting a legacy Rails application they’d inherited. I suggested that they might consider keeping the legacy app while adapting it to their micro service architecture. Within a few weeks the app was upgraded and Dockerized with the beginnings of test coverage (before this there were no tests). It also now had JSON API, and a new Svelte-based UI (according to organizational standards) with no prior Svelte experience.

  • With no Julia programming experience was able to help a high functioning team improve the quality of their Julia code base and testing which identified a critical production bug

  • Rescued the source code of a running Rails application. The developer had unfortunately disappeared. Was able to collect source code from AWS ElasticBeanstalk deployments (while having to fill in a number of missing pieces). Got it into a Github repository, upgraded from Rails & Ruby, and resolved a number of bugs and issues on it’s Vue.js frontend (having never used Vue.js before this).
