Project builds with real product thinking.

Railway booking flows are repetitive and time-sensitive, but users still need to keep login, captcha, payment, and final submission under their own control.

Built a Manifest V3 extension with popup UI, content scripts for DOM manipulation, and a Chrome Storage API layer for local passenger profile data.

Kept sensitive booking details local to the browser while reducing repeated form entry across passenger booking flows.

During infrastructure outages, people need a way to send location, phone, battery, and emergency context without depending on cellular service.

Designed the mobile-first relay flow with React Native, C++, Bluetooth Low Energy, and Wi-Fi Direct, including packet ID deduplication and NGO alert delivery.

Connected offline SOS forwarding with dashboard and WhatsApp automation so emergency packets can move through nearby devices toward response channels.

Patients and providers need medical records that are private, verifiable, standardized across terminology systems, and shareable without permanent exposure.

Built authenticated REST API routes with Node.js and Express, encrypted off-chain patient data, Solana SHA-256 hash commits, and WHO ICD-11 plus NAMASTE API integrations.

Added one-time QR record sharing with scan invalidation while keeping medical record integrity verifiable through on-chain hashes.
