Open Source Contributor • DSA & Systems / KL University

Designing & engineering high-throughput backends, distributed systems & APIs.

I’m Nikhil Kumar Panigrahi, a Computer Science student at KL University focused on Open Source Software, competitive Data Structures & Algorithms (DSA), and distributed systems. With completed backend engineering experience at WhatBytes and 7 merged pull requests across global organizations like Oppia Android and freeCodeCamp, I architect robust algorithmic solutions and high-throughput systems.

Production Engineering Projects

Verifiable cryptographic engines, hybrid semantic vector search platforms, and high-concurrency systems.

01 / 04

ProofFace

Flagship Rust Engine

End-to-End Cryptographic Visual Provenance & Face Integrity Engine

Engineered a production 7-stage verifiable provenance pipeline that cryptographically attests face authenticity and tamper-evidence on the Polygon blockchain. Rejects synthetic spoofing via an ISO/IEC 30107 compliant chrominance skin-ratio filter (≥18%), runs neural face detection, canonicalizes metadata deterministically via RFC 8785 (JCS), and anchors Keccak-256 state proofs to an on-chain Polygon Amoy smart contract.

Top 3 National Enterprise RAG

Hybrid Semantic Search & Enterprise Knowledge Intelligence Platform

Enterprise knowledge search and question-answering platform indexing 2,000+ internal documents. Combines dense vector search (MongoDB Atlas) with full-text keyword indexing via Reciprocal Rank Fusion (RRF). Integrated a low-latency RAG pipeline using Groq-accelerated Llama 3 with streaming Server-Sent Events (SSE). Awarded 2nd Runner-Up at MongoDB National Hackathon.

< 1ms Latency In-memory cached queries

< 200ms Retrieval Hybrid dense + sparse search
