👨‍💻 Engineering Profile

I am a Software Engineer focused on building high-throughput backend systems, resilient microservices, and autonomous AI automation pipelines. I enjoy working close to the network layer—whether that means implementing custom thread-pooled TCP servers in raw Java, streaming binary payloads across WebSockets, or orchestrating dynamic DAG workflows with LLMs.

  • 💼 Production Engineering: SDE Intern at Lolocab (Triptota Services Pvt. Ltd.) — building carpool booking pipelines, coupon validation microservices, and automated dynamic SEO pre-rendering engines.
  • 🎓 Academics: B.Tech in Information Technology @ Maharaja Agrasen Institute of Technology (MAIT) (GPA: 8.0 / 10 | 2022 – 2026).
  • 🏆 Honors: Conferred the Dr. J.K. Pal Memorial Award (IEEE Delhi Section, 2026) and secured the Outstanding Student Branch Award (IEEE India Council, 2025).
  • 🏛️ Community Leadership: Mentor & Ex-Vice Chairperson at IEEE MAIT — scaled the core developer team from <10 to 160+ student engineers and organized a national Agentic AI Hackathon.

🔬 Featured Projects & Engineering Highlights

⚡ Multithreaded TCP Server

Java • Socket Programming • Multi-threading • Thread Pooling

  • The Problem: Heavy web containers introduce thread startup latency and unnecessary memory overhead for raw throughput.
  • Engineering: Built a bare-metal HTTP/TCP server from scratch using raw socket streams and custom worker thread pools.
  • Benchmark: Handled 1M+ Requests Per Second (RPS) while slashing memory consumption by 35%.

📦 Source Code • 📊 Architecture & Benchmark

🤖 AI Web Scraping Automator

Next.js • Puppeteer • ReactFlow • Gemini AI • Cron

  • The Problem: Brittle CSS/XPath selectors break continuously when target websites update their DOM layout.
  • Engineering: Designed a visual DAG workflow canvas paired with Gemini LLM reasoning to extract data from raw HTML without static selectors.
  • Metrics: Delivered 85% accuracy on unstructured DOM elements with scheduled cron execution & telemetry.

📦 Source Code • 🎥 Video Demo

💬 ChatX Real-Time Platform

React.js • Node.js • Express • WebSockets • MongoDB • Zustand

  • Engineering: High-availability bidirectional messaging platform maintaining 99.9% uptime with stateless JWT authentication.
  • Features: Chunked binary file transmission supporting payloads up to 10MB.
  • Optimization: Optimized client state subscriptions with Zustand, boosting UI responsiveness by 40%.

📦 Source Code • 🌐 Live Application

🌐 Social Media Graph Backend

Java • Spring Boot • PostgreSQL • Spring Security • JWT

  • Engineering: Enterprise-grade relational backend securing 15+ RESTful API endpoints with stateless authentication.
  • Security: Configured custom Spring Security filter chains and role-based access control (RBAC).
  • Database: Designed relational schemas and indexing strategies optimized for social graph traversals.
