TeamHuddl
The back-end API used data from Betfair, William Hill, and Sportmonks to generate real-time odds and recommended bets based on team predictions.
The PHP Laravel-based API powered the mobile application and was deployed into DigitalOcean and AWS.
A wallet within the application took funds from SMS messages, PayPal payments and mass payouts using Pay360.
The API handled requests for login, registration, wallet top-ups, wallet extraction, avatars, predictions, real-time scores, historic performance, teams, team join/leave, and recommended bets.
Sadly, the application did not make it beyond the testing phase due to lack of funding.
LinkedIn Scraper
Written using Node.js and headless Chrome in response to the ban of automated tools on LinkedIn, the tool would mis-click, have extended pauses, and vary the order of certain activities to scrape user data from the social network.
Marble
Utilizing Neo4j graph database and PostgreSQL to provide insights into spending using data from Open Banking and Bank/Credit Card excel exports, the app implemented complex actuarial functions to provide financial estimates and plans for long-term saving and investment.
Docker To Elasticsearch
Created to allow trigger based PostgreSQL audit to be streamed out of the database without losing data in the event of a restart/crash of either Elasticsearch or PostgreSQL, it uses an in-memory cache and asynchronous database triggers.
