Work Experience

Frontend Developer Intern

Influcon Digitals

May 2025 - Jul 2025 Remote / Kolkata
  • Owned frontend development for the 8-section official website, translating Figma mockups into pixel-perfect, mobile-first components using React and Tailwind CSS.
  • Implemented a “sticky stacking” scroll experience with a video header, using React Hooks for dynamic section calculation and custom smooth-scroll navigation.

Full-stack Developer Intern

TimeSlotter

May 2024 - Jul 2024 Remote / Vellore
  • Designed RESTful APIs with Node.js and Express to manage user profiles, bookings, and time slot data with JWT-based authentication.
  • Refactored legacy MongoDB schemas to optimize data models, improving query performance and ensuring platform-wide data integrity.

Projects

DSA DUEL

View Project
ReactNode.jsPythonFastAPISocket.IOJudge0PineconeGemini
  • Built a real-time competitive coding platform where two users race to solve LC75 problems under a 10-minute timer, synchronized via Socket.IO with server-authoritative start times.
  • Architected a Python/FastAPI RAG microservice separate from the Node.js backend; embeds DSA content with Gemini, stores 130+ vectors in Pinecone, retrieves grounded answers via cosine similarity search.
  • Integrated a post-match AI review system where both players query an LLM-powered chatbot about the problem just solved, with answers grounded in a curated DSA knowledge base.
  • Deployed as a full-stack monorepo on Render with two independent services (Node.js + Python RAG microservice) and MongoDB Atlas for persistence.

SOCIAL MEDIA BACKEND

View Project
Node.jsMicroservicesRabbitMQRedis
  • Architected a distributed backend with 4 microservices (Identity, Post, Media, Search) fronted by a central API Gateway enforcing JWT authentication.
  • Engineered an event-driven system using RabbitMQ topic exchanges; a post.deleted event triggers asynchronous media cleanup and search index removal.
  • Implemented Redis caching for paginated API responses and global rate-limiting at the API Gateway level.

STREAMHUB

View Project
React.jsNode.jsSocket.IOFFmpegDocker
  • Captured browser audio/video using MediaRecorder API, chunking streams into 100ms fragments and transmitting to Node.js via Socket.IO (binarystream event).
  • Engineered a real-time transcoding pipeline by piping binary chunks directly to a spawned FFmpeg process, converting streams to FLV format on the fly.
  • Pushed transcoded streams to dual destinations: YouTube (RTMP) and a Dockerized NGINX-RTMP server configured for automatic HLS segmentation.
