Who I Am

Hey! I'm a B.Tech CSE student at KIIT, Bhubaneswar (2023–2027), currently in my 3rd year, maintaining a CGPA of 8.86. My passion is building backend-heavy systems that solve real, complex problems.

I started with low-level C and data structures — sparse matrices, linked lists, recursion — and grew into shipping production-grade systems: Spring Boot microservices, FHE-encrypted pipelines, and agentic LLM workflows.

I've contributed to open source via GSSoC and SSoC, merged PRs into active production codebases, and co-authored technical documentation that onboards hundreds of contributors.

Currently deep in Striver's DSA sheet with 150+ problems solved and a LeetCode rating of 1440. The endgame is Google SWE — every line of code gets me closer.

02 // Experience

Experience

Apr 2025 – Jun 2025
  • Triaged and resolved backend bugs across 2+ active repositories, delivering targeted fixes via pull requests merged into production codebases maintained by industry contributors.
  • Drove 4+ issues from root cause analysis all the way to merged PR — covering bug fixes, feature additions, and test coverage improvements.
  • Restructured technical documentation to accelerate contributor onboarding, standardizing Gitflow-based version control workflows used across the project.

What I've Built

Project 001 · Flagship
▶ Demo
CIPHER — Agentic-FHE AML Gateway
A privacy-preserving Anti-Money Laundering system where transaction data is never decrypted at any stage. Built as a 3-tier microservices pipeline combining Fully Homomorphic Encryption with an autonomous LLM compliance agent.
FHE Engine: Custom Rust-to-Java JNI bridge using Zama TFHE-rs classifies encrypted transactions into 4 risk tiers in 50–55ms with zero plaintext exposure.
Agentic AI: LangChain4j + Groq Llama 70B autonomously routes flagged transactions — reducing verdict latency to 3–8s end-to-end.
Reliability: 100% pass rate across 14 end-to-end test cases.

CodeReview Bot — AI-Powered PR Reviews
A stateless, event-driven service that plugs into GitHub webhooks and automatically reviews pull requests using AI. The full pipeline — from diff fetch to AI analysis to posted comment — completes in under 4 seconds.
Event-Driven: Webhook-driven Spring Boot service intercepts PR events, fetches diffs via GitHub REST API, and posts structured feedback automatically.
4-Layer Security: HMAC-SHA256 signature verification, per-repo token-bucket rate limiting (Bucket4j), prompt injection guards, and a global exception handler.
Production-Ready: Multi-stage Docker build deployed on Railway with health-check-based auto-restart.

Project 003
Real-Time Image Classifier
A live webcam-based visual classification system built around a trained CNN model. Frames are streamed via OpenCV to a Flask backend that runs inference and returns predictions in real time.
CNN Pipeline: Trained and deployed a convolutional neural network for multi-class image recognition.
Real-Time Stream: OpenCV handles frame capture and preprocessing at the hardware level, piped to Flask for low-latency inference.
Latency: Achieves near real-time inference with optimized preprocessing pipeline.
Integration: Seamlessly connects OpenCV capture with Flask API for continuous prediction flow.
