πŸš€ Flagship Projects Spotlight

A production-ready, full-stack EdTech platform unifying curriculum delivery, AI tutoring assistance, batch management, and automated subscription tracking.

  • πŸŽ“ Comprehensive Learning Hub: Features interactive student progress tracking, timestamped lecture streaming, resource hubs, and personal study tools.
  • πŸ€– Integrated AI Assistant: Built-in conversational tutor designed to field student questions regarding complex scientific theories, formulas, and concepts.
  • πŸ› οΈ Administrative Suite: Streamlined console for student onboarding, batch scheduling, curriculum sequencing, and role-based access management.
  • πŸ—οΈ Modern Architecture & Cloud Deployment: Engineered using Next.js, FastAPI, Python, SQLAlchemy, and Neon PostgreSQL, deployed seamlessly across Vercel and Render.

An end-to-end classification pipeline trained on real-world professional profiles to forecast and analyze career transitions.

  • Data Hygiene & Engineering: Executed rigorous missing-value imputations, multi-strategy categorical encoding, and feature scaling (StandardScaler).
  • Class Imbalance Optimization: Tackled skew using class-weight tuning, prioritizing robust Precision-Recall metrics and ROC-AUC over baseline accuracy.
  • Comparative Benchmarking: Evaluated Logistic Regression, optimized K-Nearest Neighbors (KNN), and Multilayer Perceptrons (MLPs).
  • Rigorous Validation: Deployed Stratified 5-Fold Cross-Validation alongside unsupervised K-Means clustering to verify generalization.

A centralized database management web application built to streamline utility allocation and eradicate legacy billing errors.

  • Relational Architecture: Designed robust conceptual ER/EER models fully normalized to 3rd Normal Form (3NF) to ensure zero redundancy and eliminate transitive dependencies.
  • Financial Ledger & Security: Developed secure backend transaction pathways preventing double-billing and supporting real-time wallet updates.
  • Interactive Data Visualizations: Utilized SQL aggregation pipelines paired with Chart.js to display longitudinal 6-month historical power consumption trends.
