Hi, I'm Kushalpal 👋
Full-stack developer building real-time systems and AI-powered tools.
kushalpalbishnoi@gmail.comAbout
I'm a Computer Science undergrad at JSS Academy of Technical Education, Noida (2023–2027), currently working as a Software Engineering Intern at Greentree Global. I enjoy building across the stack — from real-time chat with WebRTC to LLM routing pipelines — and I'm an avid competitive programmer with a peak LeetCode rating of 1789 (top 9%).
Work Experience
Greentree Global
June 2026 – Present- Building a production-ready Green Building Certification Audit platform used by 10+ auditors, digitizing 200+ evaluation criteria across multiple audit categories.
- Designed scalable RESTful backend services using Express.js and PostgreSQL, modeling 10+ normalized tables with indexing for efficient querying and extensibility.
- Implemented secure authentication, role-based access control, API rate limiting, structured logging, and cloud-based document storage to support production deployment and future commercialization.
Skills
My Projects
Check out my latest work — from LLM routing pipelines to real-time messaging platforms.
WhatsApp Notification Router
Multimodal pipeline that classifies WhatsApp notifications (notify, digest, mute) across users and groups. Hybrid decision engine combining heuristic rules with Llama 70B on AWS Bedrock, evidence retrieval via Gemini embeddings with z-score semantic matching (no vector DB needed), multi-provider LLM infrastructure with rate limiting and retries, and prompt injection guardrails.
My Chat App
Full-stack real-time messaging platform with 1:1 and group chats, offline message storage in MongoDB, and WebRTC video/audio calling with SDP negotiation, ICE candidate exchange, and STUN/TURN fallback. AWS S3 presigned URLs for secure direct uploads, JWT auth, and a responsive React UI with Framer Motion.
Eco Query Group
Chrome extension that routes queries between cloud LLMs (ChatGPT) and local LLMs (Ollama), cutting API cost and latency. Browser-native semantic routing engine using vector embeddings and token budgeting, ChatGPT DOM injection for seamless in-browser UI, and an analytics dashboard for usage and performance monitoring.
