Professional Projects

1. NFC-RFID IoT Project

This is basically a research project for controlling electronic devices that are on close vicinity by scanning tags using radio-frequency(RF), Near-field communications(NFC), and Bluetooth Low Energy(BLE) technologies i.e playing music, controlling the lighting in the house, scanning cards to lock and unlock the doors, tracking items like keys, wallets, or bikes.

The project is based on Java pi4j framework, which is an object oriented I/O API that grants Java developers full access to input-output capabilities of Raspberry Pi. It uses Raspberry Pi Model 3B as the controller and and RC522 chip as the sensor module for this project. However, other sensor modules can be used i.e PN532 chip, PVC SRT512 modules.

It is based on Serial Pheripheral(SPI) communication protocol sensor with modules operating at a radio-frequency of 13.56 MHz.

2. Rental Management System

Web-based

Mobile-based

The application not only helps in managing all kind of individual and cooperate rental properties but also keeps track of all financial records in an automated fashion. It generates all financial statement. The application also coordinates all financial and client information throughout the system to maintain consistency, efficiency and accuracy were improved as well.

I used Java and php. The database is MySQL. Material design was implemented on the UI. Also Restful APIs and Volley libraries played a vital role in making HTTP requests to the server

Freelance Projects

1. LD Talent Projects

Reviewed a project from one of the LD Talent Engineers, the project blog was entittled How to create an Amazon Price Tracker using Python

Personal Projects

1. Tic-tac-toe Board Game

The app allows users to play Tic-Tac-Toe, a 3x3 grid-based game where players take turns marking spaces with "X" or "O" to achieve three symbols in a row, column, or diagonal. It is good for people who want to develop their logical thinking and build problem-solving skills, whether they are a casual players or a strategic masterminds.

It supports two modes:
Single-Player Mode: The user (Player X) plays against an AI (Player O), which uses the Minimax algorithm to ensure optimal play.
Multiplayer Mode: Two human players (Player X and Player O) take turns on the same device.

The game revolves around 3 algorithms in multiplayer mode; turn management, win detection and game state handling, whereas the AI mode uses the famous minimax algorithm which functions recursively making it unbeatable/forces a draw in most cases.

2. Android-based Student Attendance System.

This software captures the class attendance of the students with the help of its unique biometric(uses fingerprint) feature for authenticating students. I used Java to develop the components of my application and also the GUI for the application. I also used SQLite because it supports standard relational DB features: SQL syntax, transactions and prepared statements. This database requires limited memory at run-time (say 250 KB).

Here is the Github project link StudentAttendanceCapture

The extration of the fingerprint minitae was done by a Suprema fingerprint scanner. The extracted fingerprint is therefore Stored as a pitmap in the database

3. Healthcare Decision Support System

The software application was based on knowledge base model, rule of reasoning used to infer disease from the presence of certain symptoms. It provides ease of diagnosing disease in users hand. This project would be basically taking symptoms from the patient or the related user and then taking the case history which would be used for proper analysis of the condition that the user might be suffering from. Github Project link M diagnosis

Used Naive Bayes Classifier(Here is the accuracy justification Bayesian Model Accuracy Justification ) as the inference engine, infer the disease as per pressence of certain symptoms. Also, GPS location tracking google API for nearest health faciity navigatin

4. Titanic Survivors Data Analysis

This project was bassically to use Python numpy and pandas libraries in the analysis the survivors during the sinking of the Titanic ship based on age, sex, locality and famiy size.

View the Project Source TITANIC_SURVIVORS_DATA_ANALYSIS

5. Real-time Chat Application

The application allows easy, secure and efficient chat with the registered users. The database used is the Firebase real-time support and cloud.

The technologies used is Java programming and Firbase Messaging Console(FCM). Here is the link to the github repo Lets Connect
