Android Engineer | Kotlin Multiplatform Developer | Open Source Mentor, Maintainer & Contributor

Android Developer with 1.7 years of production experience (0.2 years full-time + 1.5 years internships) across 10+ mobile applications spanning 4 companies (Swipe, Mifos, TLDE Technologies, MobileByteSensei), specializing in Kotlin, Jetpack Compose, and Kotlin Multiplatform (KMP) for Android, iOS, Desktop, and Web.

Currently SDE-1 Android at Swipe (YC S21), where I own end-to-end feature flows — settings, products, expenses, and indirect income — after modernizing 15 production flows comprising 70+ screens by migrating legacy XML UI to Jetpack Compose, implementing a scalable multi-module MVI architecture, and introducing Gradle convention plugins that reduced build script duplication by 80%. Resolved 50+ production crashes and UI defects using Firebase Crashlytics and Intercom.

Maintainer and Mentor (GSoC & C4GT) at Mifos Initiative, selected for Mifos Summer of Code 2025 ($2,500 stipend). Migrated 20+ modules to Kotlin Multiplatform, authored 120+ pull requests (98% merge rate), reviewed 230+ PRs, and mentored 10+ new open-source contributors.

Also building ExpenseTrackr — a privacy-first, offline personal finance tracker in KMP/CMP (Android, iOS, Desktop from one codebase), currently in Google Play closed testing.
