Arkham Labs is a DC-inspired coding platform for mastering data structures and algorithms. I built Arkham Labs as part of the ChaiCode LeetLab Challenge, aiming to reimagine the classic coding prep experience but with my own creative spin.As a huge Batman fan, I gave the platform a batman-themed aesthetic, custom built background images in Figma, no UI libraries for the components and tasteful animations using framer motion.<h3>Key Features</h3><ul><li>AI Assistant (Alfred) Integrated using Groq API, helps you debug and gives you hints right within the code editor.</li><li>Real-time Collaborative Editing Built with Liveblocks, lets multiple users code together in sync, like Google Docs for coding.</li><li>User Stats &amp; Contribution Graphs Similar to LeetCode, track your progress visually and stay motivated.</li><li>Dynamic Playlists Create, manage, and solve problems via custom playlists.</li><li>Light/Dark Mode &amp; Smooth Animations Built from scratch for a clean, intuitive UX.</li></ul><h3>Tech Stack</h3><ul><li>Frontend: React.js + Tailwind CSS + Framer Motion + Figma</li><li>Backend: Node.js + Express.js</li><li>Database: PostgreSQL (self-hosted)</li><li>ORM: Prisma</li><li>Code Execution: Judge0 (Dockerized, 4-container setup)</li><li>AI: Groq API (llama3-70b-8192)</li><li>Collaboration: Liveblocks</li><li>Deployment: Azure VM + Docker + PM2 + ecosystem.config.js</li></ul>This project helped me grow immensely, from real-time sync logic to VM deployment, container orchestration, and first-time AI integrations.

As part of my Modern Application Development course at IIT Madras, I developed an Influencer Engagement and Sponsorship Coordination Platform using flask that bridges sponsors and influencers, facilitating seamless collaborations for mutual benefit.

The problem statement was to make a software which connect Sponsors and Influencers so that sponsors can get their product/service advertised and influencers can get monetary benefit.

Implemented features include creating and managing campaigns, two-way request handling and negotiation, dummy payment processing, and PDF+CSV transaction reporting. Utilized role-based access control for user authentication and authorization.

Additionally, I created RESTful APIs for each model in the database.

🗝️ Key Features:

Sponsors can easily find the right influencers for their products/services
Influencers can monetize their reach and creativity
Seamless campaign management and tracking
User authentication and personalized profiles
Booking system for influencer-sponsor collaborations
Rating and feedback mechanism
Comprehensive admin dashboard with analytics
Interactive charts for data visualization (using ChartJS)

As part of my Modern Application Development-2 (MAD2) course at IIT Madras, I developed a software for users and administrators to enhance exam preparation across multiple courses. It offers a structured and interactive environment for students to take assessments and track their progress, while administrators can manage courses, quizzes, and user accounts.

🡺 Key Features:
🎯 JWT-based authentication with role-based access control (Admin/Student).
📊 Real-time performance analytics using Chart.js
📱 Mobile-responsive Vue.js frontend
⏰ Celery-powered daily reminders &amp; monthly reports + async jobs for CSV export.
🔒 Protected API endpoints with proper authorization
🛑 Deadline-based availability control +Single-attempt restriction capability. 
💳 Secure payment processing for premium quizzes +Transaction history tracking
✨ Responsive design using Tailwind CSS + Intuitive navigation with Breadcrumbs

🡺 Designed scalable DB schema with 10+ interconnected tables.
🡺 Implemented CSV export for quiz results and transactions.
🡺 Reduced server load by using Redis caching.
🡺 Created 25+ RESTful API endpoints with Flask-RESTful. 
🡺 Implented Email rate limiting so that the emails don't cross the free tier.
