Work

Things that exist, described accurately.

Three pieces of work, each labelled with what it actually is. One is a shipped product with paying customers, one is infrastructure we run every day, and one is a prototype we have not released. We would rather you trust the third label than be impressed by a fourth.

01Shipped

Yojika — offline-first GST billing

A Flutter billing application for Indian small shops on Windows and Android. Local-first data, optional sync, GST-compliant invoicing, and printed invoices in all 22 official Indian languages — in ~15 MB against a market leader’s ~250 MB.

  • Flutter · Windows + Android
  • ~15 MB install
  • 22 invoice languages
  • Built solo in ~4 weeks
02Running in production

A 12-language content pipeline that publishes itself

Scheduled SEO article generation, translation and publication across 12 Indian languages, running unattended every morning at 06:49 IST. Drafts auto-merge only after passing an automated quality gate; anything that fails never reaches the domain.

  • GitHub Actions · daily cron
  • 12 languages
  • Gated auto-merge
  • Live on yojika.com
03Prototype — verified on hardware

A dual-camera 4K capture engine for iOS

Simultaneous front and rear 4K30 recording on iPhone, with one layout solver driving both the live preview and the recorded composite — so the output matches the preview exactly rather than merely resembling it. Not released; listed here as engineering, not as a product.

  • Swift · AVFoundation MultiCam
  • 4K30 both cameras
  • Core Image compositor
  • Not in the App Store
