An AI-powered facial recognition software for attendance marking and security monitoring. In this system, members' faces captured by network cameras would be subsequently recognized, and their details would be logged to an Elasticsearch server.

I developed, improved, and maintained this project's back-end components, including the API, recognition pipeline, scheduler service, and health monitor, for over three years using Python. I also developed components of the front-end application using React and Angular.

Supplier Performance App

A web application for initiating and conducting performance reviews of suppliers in a supply chain environment. I worked on this application's back-end and front-end components from initiation to deployment.

Room Type Deduplicator

A system for matching hotel rooms based on descriptions provided on online booking sites. I developed a Spring Boot-based REST API, a machine learning-based algorithmic system for matching hotel rooms from online booking sites, and a hotel room object detector using YOLOv4. I scraped hotel information from online booking sites using Selenium.

Number Plate Detection and OCR

I collaboratively worked on vehicle license plate detection and OCR models to recognize vehicle numbers in real time. Network cameras were fixed at the entrance to the office premises, where license plate numbers were identified to give statistical results of the vehicles passing through the entrance.

Scraping Member Details from Websites

Scraped names and details of fellows and members of universities from multiple academic-related websites using Beautiful Soup to create a CSV file to be used as input to an SQL database. I also handled filtering, pagination, and exceptions from missing data.

Creating Python Layouts for ID Card Classification

Created layout classes in Python to classify a given ID card (a driver's license, national ID, residency permit, voter's ID, etc.) by its version. I also developed enhancements to the existing product at Persona Inc.

Smart News Analyzer for Company Stocks

Developed a Python-based program to read any new news articles on Khaleej Times and analyze the article to predict if the news article will affect the stocks in companies listed in the Dubai Financial Market. If any article is predicted to affect stocks, an email is sent to the subscribers immediately. This would help subscribers (investors) perform fundamental analysis on the stocks and eventually help in their buy/sell decisions.

Interactive Brokers Trading Bot

Built a trading bot in Python using the Interactive Brokers API and Interactive Brokers gateway. I implemented various strategies like the moving average crossover strategy, Bollinger Bands Strategy, and mean reversion strategy.
