I'm a Software Engineering & Information Systems (GLSI) student passionate about building real-world solutions, from AI-powered web applications to embedded systems. I enjoy bridging the gap between hardware and software, creating projects that combine practical engineering with modern technologies.

Languages Python JavaScript TypeScript Java Solidity C SQL PHP CSS

Frontend React Angular Vite Thymeleaf HTML/CSS

Backend Flask FastAPI Node.js Express Spring Boot

ML / AI scikit-learn XGBoost pandas NumPy

Databases SQLite PostgreSQL MySQL MongoDB

Embedded Systems Arduino MFRC522 (RFID)

Blockchain Ethereum Hardhat ethers.js Solidity

DevOps & Tools Git GitHub Actions Railway Docker Maven JWT REST APIs

AI-powered phishing URL detection tool

A full-stack cybersecurity tool that classifies URLs as phishing or legitimate using a trained XGBoost model. Integrates VirusTotal v3 and Google Safe Browsing APIs for enriched threat intelligence.

• Built with Python / Flask backend + vanilla JS frontend
• Trained on the LegitPhish 2025 dataset with 30+ feature extractors
• CI/CD via GitHub Actions, deployed on Railway
• Includes a /health endpoint, backend URL sanitization, and a full pytest suite (30+ tests with mocked APIs)

Hardware-meets-web attendance tracking

An end-to-end attendance system using Arduino Uno + MFRC522 for card scanning, with a Flask + SQLite backend and a React/Vite frontend.

• JWT-based authentication
• Per-student history modals, class/group filtering
• Unknown card alerts
• Excel export for attendance reports

Cloud-based file distribution with payments

A Node.js / Express + React platform supporting Cloudinary ZIP uploads, download-via-redirect, Stripe payments, and a blockchain service integration.

• PostgreSQL database
• Multer for file handling
• Secure download flows

Spring Boot inventory & order management app

A full-stack web application for managing product inventory and processing orders, built with a layered Spring MVC + JPA architecture.

• Spring Boot 4 backend with Spring Data JPA and Bean Validation
• Thymeleaf templating for a responsive admin dashboard
• MySQL database with duplicate product code enforcement at both service and DB level
• Product image management with placeholder fallback, payment/order form

Decentralized jury voting on Ethereum

A blockchain-based voting system where an admin registers candidates, randomly selects 3 jury members via an on-chain Fisher-Yates shuffle, and manages the voting lifecycle entirely through a smart contract.

• Solidity smart contract deployed on a local Hardhat node
• Jury members each receive 10 votes to distribute freely among candidates
• Pure HTML/JS + ethers.js v6 frontend — no build step required
• Full event logging: VoteCast, JurySelected, VotingStarted/Ended

PHP & MySQL library management system

Full-stack web app built with PHP and MySQL featuring a public catalogue, member authentication, borrowing & reservation system, and a complete admin dashboard with reporting and email notifications.

Collaborative project management platform with real-time chat

Full-stack capstone project (FastAPI + React) built across 3 Scrum sprints, letting students manage projects, assign Kanban tasks, invite teammates, and chat in real time — with teacher supervision and grading built in.

• FastAPI + SQLAlchemy backend with JWT auth (bcrypt-hashed passwords, sessionStorage tokens)
• Drag-and-drop Kanban board (To Do / In Progress / Done) with priorities, due dates, and comments
• WebSocket group chat per project: typing indicators, read receipts, file attachments, auto-reconnect, toast notifications
• Email-based invitation system with token expiry
• Teacher dashboard for cross-project supervision and graded feedback (0–20)

Full-stack CRM platform with AI-powered insights, built during my summer internship

An enterprise-style CRM developed during my summer internship, for managing clients, prospects, subscriptions, opportunities, invoices, and tasks across three educational product lines. Combines a Spring Boot backend, an Angular frontend, and a dedicated Python AI microservice — all containerized and orchestrated with Docker Compose.

• Spring Boot 4 + Angular 21 full stack with JWT authentication and strict Role-Based Access Control (Admin / Commercial / Support), enforced at both the API and UI layers with ownership-level checks (e.g. commercial agents only edit their own leads/tasks)
• AI microservice (Python/FastAPI + scikit-learn) for lead scoring, churn prediction, and product recommendation — falls back to a documented heuristic when no trained model exists yet
• Social media data pipeline: signature-verified Meta Lead Ads / WhatsApp webhooks normalize real acquisition data (channel, engagement, response time) directly into the CRM for smarter lead scoring
• Interactive Kanban pipeline for opportunities (7 stages, drag-and-drop) built with Angular signals and @angular/cdk
• Live dashboard with real-time KPIs, plus Power BI integration via direct MySQL views and DAX measures for executive reporting
• Fully containerized with Docker Compose (MySQL, Spring Boot, FastAPI, Angular/Nginx) for one-command local deployment
