OG — Optimal Guide

Nov 2025 - Feb 2026

Architected a full-stack adaptive learning platform with a real-time recommendation engine that dynamically adjusts DSA problem difficulty and topic sequencing based on user accuracy and activity patterns, eliminating 100% of manual curation. Designed and secured 10+ RESTful API endpoints using Django REST Framework and JWT Authentication, enabling stateless, scalable session management across all client interactions. Built an end-to-end performance analytics dashboard (Angular) with problem tracking and solved-status updates, providing actionable insights into user progress and weak areas. Configured a dual-database environment (MySQL for production, SQLite for local dev) with professional migration workflows and environment-specific configuration management. Applied OOP principles and modular Django architecture across the entire codebase to ensure maintainability, scalability, and clean separation of concerns.
