Work Experience

Full Stack Developer (Intern)

Valaxia LLP

Dec 2025 - Present Bengaluru
  • Architected and built an AI-powered athlete discovery platform using React, Next.js, Node.js, and PostgreSQL, ensuring scalable service design and structured data flow.
  • Designed RESTful API contracts and database schema to enable reliable frontend-backend communication and maintain data consistency across user workflows.
  • Implemented authentication and API validation using middleware patterns in Node.js, preventing invalid states and ensuring secure access control.
  • Optimized backend performance and deployed using Docker and Vercel with CI/CD pipelines, improving response latency and ensuring production stability.

Blockchain Developer (Intern)

Dehix

Aug 2025 - Dec 2025
  • Developed Ethereum smart contracts using Solidity, Hardhat, and Foundry, focusing on deterministic execution and secure on-chain logic.
  • Integrated Chainlink Oracle services to enable reliable off-chain data ingestion, allowing smart contracts to interact with real-world data sources.
  • Performed gas optimization and contract testing to reduce transaction costs and improve execution efficiency for end users.
  • Worked on protocol-level debugging and system behavior analysis, identifying edge cases and improving reliability of decentralized workflows.

Projects

SanskritAI — AI-Based Web Application

ReactNode.jsFastAPIXLS-R
  • Built an end-to-end pronunciation training platform to provide real-time feedback on speech accuracy for learners.
  • Addressed the challenge of inconsistent pronunciation by enabling phoneme-level error detection and feedback.
  • Implemented a full-stack system using React, Node.js, and FastAPI, integrating XLS-R for feature extraction and GOP-based scoring; achieved ROC-AUC of 0.94 across 1500+ samples.

Phantom-Read Cross-Chain Bridge Attack Simulation

AnvilEthereumSolidityNode.jsEthers.js
  • Built a multi-node cross-chain simulation using Anvil and Ethereum test networks to model forked and canonical chain states.
  • Analyzed relayer behavior under eventual consistency, identifying how non-canonical data propagation leads to invalid state transitions in cross-chain bridges.
  • Implemented Solidity bridge contracts and a custom relayer using Node.js/Ethers.js to simulate asset transfers and validate cross-chain state consistency.

Blockchain-Based Secure E-Voting System

EthereumSolidityWeb3.jsGanache
  • Built a decentralized voting system on Ethereum using Solidity for tamper-proof vote recording and on-chain state integrity.
  • Implemented voter authentication and deterministic vote tallying using Web3.js, preventing double voting and ensuring verifiable results.
  • Simulated 1000+ transactions using Ganache and optimized execution to~387,957 gas per vote for cost efficiency.
