measuringTape

TypeScriptSolidityEthereum (Sepolia)IPFS

Full-stack decentralized platform for reporting civic issues (potholes, broken streetlights, garbage dumps) with every report stored on IPFS. Issues verified by the local community via real-time on-chain consensus, then received by authorities/municipality; all actions taken are updated on-chain and re-verified via community consensus. Solidity smart contract deployed on Sepolia for immutable, tamper-proof reports, consensus results, and reputations, enabling verification and user accountability.

Dermalyze

TensorFlowSolidityEthereum (Sepolia)IPFS

Co-built a full-stack AI-powered skin-disease detection platform pairing deep-learning diagnostics with blockchain-verified medical reports. Designed and deployed Solidity smart contracts on Ethereum Sepolia for immutable, tamper-proof verification of medical reports. Engineered IPFS-based decentralized storage for secure, persistent report data.

Working on

Bitcoin Mempool Package Optimizer

PythonBitcoin Core

Building a Bitcoin block-selection research framework to evaluate 3 transaction-selection strategies — baseline, ancestor package, and improved optimization — using controlled Regtest mempool snapshots.
Implemented DAG-based dependency modeling using NetworkX to resolve ancestor/descendant relationships and CPFP package feerates against simulated mempool snapshots.
Evaluated the three transaction-selection strategies in controlled simulations, with the improved heuristic achieving 18.4% higher selected transaction fees than the baseline on a specified test scenario.
Integrated an interactive React + Vite dashboard and FastAPI backend for real-time visualization of DAG topologies and revenue curves.

Sentinel

FastAPIPostgreSQLReactPython

Co-designing a self-hostable, local-first platform that helps investigators in analysing complex insider-threat scenarios involving multiple heterogeneous evidence sources — authentication and file-access logs, USB and network events, badge data, CCTV video, and scanned documents — into a unified incident timeline and evidence graph.
Owning the Backend + Security track: Architecting an audit and integrity layer inspired by chain-of-custody principles — SHA-256 hashing of evidence at ingest, tamper detection by re-hashing, and audit records for all processing operations.
Part of a research-oriented 4-member team exploring whether multimodal evidence correlation improves insider-threat detection over single-source analysis, using public datasets (CERT, LANL, VAST 2009).

FreeDee

TypeScriptSolidityEthereum (Sepolia)

Built a trustless milestone-based payment locking and dispute arbitration on Ethereum. A Solidity smart contract replaces the centralized escrow intermediary. Funds are locked on-chain, released per-milestone, and disputes are resolved by a mutually agreed arbitrator — all without a backend or database.
