I build and ship real products end-to-end — Flutter apps, Next.js backends, Postgres, and the infra to run them. Currently building the DRW Skincare ecosystem: a POS app used by ~1,000 beauty consultants and the platform behind it.
I'm a self-driven developer who likes owning a product from idea to production — designing the data model, building the app, wiring the API, and keeping it running on real infrastructure.
Most of my time goes into the DRW Skincare ecosystem: a Flutter point-of-sale app used daily by around a thousand beauty consultants, its Next.js + PostgreSQL backend, and a handful of other web apps for clients and side projects.
Products I've designed, built, and shipped end-to-end.
Quran-reading app that verifies recitation from the user's voice via real-time forced alignment (no tajwid scoring — just live "heard-word" tracking). Speech recognition runs fully on-device (Zipformer2 CTC phoneme model, ONNX INT8 ~73 MB): audio never leaves the phone, works offline, with automatic server fallback. Community layer: public "Jelajah" groups, collaborative split-page reading (up to 3 readers, per-member colour building a whole-Quran "Peta Khatam"), khatam cycles, endless leaderboards, badges, realtime chat/DM, and universal-link sharing. Flutter (Android/iOS/Web) + FastAPI + PostgreSQL + ONNX Runtime, self-hosted on a VPS. On Google Play and the App Store; live at berquran.com.
Flutter point-of-sale app used daily by ~1,000 beauty consultants across Android, iOS & Web. Full-online architecture, Riverpod state management, thermal-printer receipts, per-reseller stock, tiered pricing, and a loyalty/coin wallet — backed by the Next.js + PostgreSQL platform. On Google Play and the App Store; web build live at pos.drwskincare.com.

Flutter companion app for DRW Skincare patients — guided photo and video capture that documents skin-treatment progress over time, walked through step by step by an Indonesian voice assistant ("Buperi"), backed by a dedicated journey API on the DRW platform. Android & iOS, built alongside the POS app.
Member app and back office for a women-only gym & pilates studio in Yogyakarta — class booking, QR check-in that deducts session credits, membership and expiry tracking, push notifications, and in-app payment with a native QRIS flow via Xendit. Flutter app rewritten from React Native, on a NestJS + PostgreSQL API. Live at wondher.mkwiro.online.
