Portfolio
Recent Works
14 projects spanning Web3, AI/ML, compilers, backend & mobile.
CX Compiler & VM
Engineered a complete compiler pipeline from scratch: Lexer → Parser → Semantic Analyzer → Optimizer → TAC → Code Generator → VM. Supports scoped symbol tables, static type checking, recursion, and constant folding. Validated with 18+ automated test suites.
Chess AI Analyzer
Built a Residual CNN with dual policy/value heads targeting a 4,672-action move space. Trained on Stockfish engine data for move prediction, positional evaluation, and blunder detection. Exported to ONNX for cross-platform inference with AlphaZero-style self-play.
HRMS — Modular Monolith
Architected a modular monolithic HRMS backend in .NET 8 using Clean Architecture, CQRS, MediatR, AutoMapper, FluentValidation, and PostgreSQL with EF Core. Exposes a HotChocolate GraphQL API secured via JWT with Azure Key Vault integration, paired with a Next.js 16 + React 19 + TypeScript + Apollo Client frontend.
SIH FHIR EMR — Healthcare
Led Team at Smart India Hackathon 2025 (Ministry of Ayush/AIIA). Built a FHIR R4-compliant EMR microservice integrating 4,500+ NAMASTE/AYUSH terms, WHO ICD-11, SNOMED CT, and LOINC, with FHIR Bundle/ConceptMap APIs, ABHA OAuth 2.0 security, and ISO 22600 audit trails. Secured Top 10 among 150+ teams.
MNIST Neural Network
Built a from-scratch neural network for MNIST digit classification achieving 97.3%+ accuracy. Implements ReLU in hidden layers, Softmax output, full forward/backward propagation, and gradient descent optimization using NumPy — no high-level frameworks required.
Potter-XYZ
A decentralized, real-time betting game built on Solana. Each bet resets a countdown timer, and the last bettor wins the pot. Integrated with Jupiter for token swaps, Solana wallet adapter, and DAO-ready logic.
WALLATION
A secure and user-friendly Web3 crypto wallet that supports seed phrase generation, real-time balance display, and fund transfers. Built with robust encryption and privacy mechanisms.
ChainPort
A lightweight wallet adapter that improves transaction security. Fetch balances, sign messages, and send funds via trustless, Public-keyless communication.
FINTRACK
An Android app that reads and filters SMS for UPI/bank transactions using Kotlin. Supports SBI, GPay, PhonePe, Paytm, and more.
Medi Locker
Secure platform to store, manage, and access medical records. Built using HTML, CSS, JS, Node.js, Express.js, and MySQL. Top 10 at JECRC Hackathon (250+ teams).
WebSocket Chat
A real-time chat app using Node.js and WebSocket on the backend, and React with TypeScript on the frontend (Vite).
SPL Token Creator
A no-code dApp built with React to create custom SPL tokens on the Solana blockchain with just a few clicks.
Ethwallation
A secure Ethereum wallet built using Python and MySQL. Includes wallet generation, transaction signing, and balance checks.
