Generalist back-end engineer with a proven track record at early stage startups. Seeking engineering challenges in new stacks and new domains.

Generalist, experienced lead software engineer with a particular knack for picking up new technology quickly, and solving deep difficult problems in existing codebases.

My personal hobbies include playing music, producing music, and self improvement.

Projects

Better Angel's Bookstore

Containerized Django, Postgres web service, React Native mobile app client for a fictional Bookstore reservation system. This project was implemented as an asynchronous interview for a senior full-stack engineer position at https://betterangels.la I completed this project in a week, I took this as an opportunity to learn Django and React Native from scratch, and chose these technologies as a good poc for scrappy yet foundational back-end/front-end mobile app product. I was able to quickly bootstrap myself despite my unfamiliarity by leveraging ChatGPT and quick start tools like React Native Expo. I also took this opportunity to poc using the LLM as a core source contributor - generating documentation, tests, modules in Django, app pages and components in React Native. I'm extremely pleased with the results and the learnings, and feel prepared for the coming LLM developer revolution. For more detail see Readme, written by ChatGPT! See More
