Case study
দেনা-পাওনা · ব্যক্তিগত খরচ · বাংলা UI
TakaMinder helps people stop guessing who owes what: lent money (Paona), borrowed money (Dena), settlements, accounts, and agreements live in one calm Bengali interface. Transaction history stays on-device by default; optional Drive sync is encrypted and user-controlled — no ads, no tracking.

Problem
Typical money trackers assume full-time connectivity, heavy accounting UX, or English-first flows. Shopkeepers, roommates, and families still rely on notebooks and scattered chats; losing the phone meant losing the ledger.
Solution
A React Native (Expo) app with local SQLite and conflict-aware sync paths, Bengali-first screens for dashboard, দেনা পাওনা, হিসাব, and চুক্তি flows, plus optional Google Drive backup and contact-backed entries so adding people stays fast.
Outcome
10K+ downloads in six months, strong Play ratings, featured in local fintech coverage — shipped solo and bootstrapped on the Google Play Store.
What I shipped.
I designed and built the entire mobile product end-to-end in React Native and Expo — UI, navigation, data layer, backup flows, and release pipeline.
