Accountant | Personal Finance Management

Personal finance management built using Ruby on Rails 7 as the back-end API, serving RESTful resources using JSON API specifications, and Vue 3 as the front end.

On the front end, I'm using Plaid Link to connect a user's bank account to the system, and using the information, the back end leverages the Plaid API to aggregate account information and financial transactions.

It's also leveraging Plaid webhooks to get signals from Plaid when additional data can be fetched from the Plaid API. I'm using Sidekiq for asynchronous tasks, such as fetching data from the Plaid API and automating account balance refreshes.

I initially used MongoDB with Mongoid to prototype this but have since migrated to using PostgreSQL.

Rate-a-resto

Rate-a-resto is a restaurant rating system that I built with a React front end and Ruby on Rails API. I used Semantic UI for the front end design and implemented RESTful resource endpoints for the back end, adhering to JSON:API specifications. The authentication is done using JSON Web Tokens (JWT), generated on sign-in, and passed back to the client through response headers.

Payments Processing Platform for Construction Management Company

http://www.procore.com
I led a team to develop a payments processing and invoicing platform for construction professionals using Ruby on Rails as a back-end API and React on the front end. We used Stripe API as a KYC tool and also as a way to initiate payment requests and charges.

Lead Developer for Consumer Pages Re-design

I acted as the software developer in an ongoing re-design of the Giftly consumer-facing website. Working with other developers, designers, product managers, and product owners to set technical specifications, timelines for delivery, and prioritizations, and led back-end and front-end software development in Ruby on Rails and Vue.
