About

I'm a mobile developer focused on building React Native apps that respect the user — no bloated permissions, no dark patterns, no data collection just because I can. My latest project is FlashQR, a QR & barcode scanner/generator I built because every existing app in the category was either ad-riddled or gated behind a paywall. It reads 13 barcode formats and generates 19 kinds of QR codes — Wi-Fi, vCards, UPI, WhatsApp, calendar events, and more — through real forms instead of hand-typed payload strings. Everything stays on-device: encrypted storage, zero network requests, no account. I want to keep building small, focused tools that solve a real problem well, and get better at distribution, not just code. Always happy to connect with other indie builders.

FlashQR: QR Scanner & Creator - Scan barcodes, build 19 QR types — offline, no ads

FlashQR reads every common barcode format (QR, Data Matrix, Aztec, PDF417, EAN, UPC, Code128/39/93, Codabar, ITF) and builds QR codes for 19 use cases — Wi-Fi, vCard, UPI payments, WhatsApp, calendar events, coupons, and more — with real forms instead of hand-typed payload strings. Customize with colors, shapes, and a logo. Everything is stored locally and encrypted, with a searchable, exportable history. No ads, no account, no paywall, and the app makes zero network requests of its own.
