KUDO (Kudoway)

https://kudoway.com/
Created a multilingual conferencing platform with human-powered live interpretation having a back end in Ruby on Rails (RoR) and a front end in AngularJS. I was responsible for implementing new features, adding spec coverage (unit tests and integration tests), and fixing daily reporting bugs.

SPEC (IOS application)

Developed a swift-based application for computer and mobile accessories (more like an eCommerce application). I was the back-end developer there. My responsibilities were to refactor already written code, resolved issues with N+1 queries, and DRY code. I developed new endpoints according to requirements.

Virtual Common Wealth

Developed a React Mative base application monitoring users' transactions and calculating tax accordingly. I was the back-end engineer responsible for integrating Plaid with the back end to fetch users' transactions and save them to the local database for fast retrieval in future requests.

XDOME: Colorado's Legal Statute Editor

http://xdome.s3-website.us-east-2.amazonaws.com/
XDOME is an advanced editing software crucial for the Legal Services Department, facilitating the precise drafting and revision of the Colorado Revised Statutes. Before XDOME, all work in this department was done in WordPerfect. With its comprehensive suite of features and intuitive interface, XDOME streamlines collaboration among legal teams, ensuring accuracy and efficiency in statute writing. Its robust version control and real-time tracking capabilities maintain a clear audit trail of legislative changes. Integrated tools for legal research, citation management, and cross-referencing further enhance the drafting process. XDOME is an indispensable asset in upholding the integrity and accessibility of the foundational laws of Colorado.
