Android Engineer | Kotlin · Jetpack Compose · Kotlin Multiplatform | Mobile Maintainer @ Mifos Initiative

Android engineer working on software businesses depend on: a GST billing platform used by 5L+ Indian businesses at Swipe (YC S21), and open-source banking apps at the Mifos Initiative, where I'm mobile maintainer. Most of the work is legacy modernization — turning code that's hard to change into code a team can build on.

At Swipe, I own the settings, products, expenses, and indirect-income features end to end — UI, domain, data, and network. I've migrated 16 feature modules and 100+ screens from legacy XML to Jetpack Compose, replacing fragment-held state with a multi-module MVI architecture, and introduced Gradle convention plugins that cut build-script duplication by 80%. I took over an unattended Crashlytics backlog and resolved 50+ production crashes; the app maintains 99.8% crash-free sessions. Converted from intern to full-time SDE 1 in six months.

At the Mifos Initiative, I'm a mobile maintainer — I review, approve, and merge contributions across open-source banking apps used by financial institutions in developing markets. I proposed and built the core:ui module for the Mifos Android Client, now the foundation for all UI in the application. I've authored 111 merged pull requests across 3 production repositories, migrated 20+ modules to Kotlin Multiplatform, modernized 150+ screens, and reviewed 290+ contributor pull requests.

Reviewing 290+ open-source PRs taught me more than writing them did. I think about consistency, migration paths, and what a codebase looks like a year from now — not just whether the feature ships.

Also the creator of ExpenseTrackr — an offline-first personal finance tracker built in KMP/CMP (Android, iOS, Desktop from one codebase), live on Google Play.

• 🏗️ Clean Architecture, MVI & MVVM — multi-module, feature-modular apps
• 📱 Modern Android — Jetpack Compose, Material Design 3, type-safe navigation
• 🚀 Kotlin Multiplatform (KMP) & Compose Multiplatform (CMP)
• 🔄 Dependency Injection — Hilt (Android), Koin (KMP)
• 🔥 Production debugging — Firebase Crashlytics, Analytics, Intercom
• 📦 Release management — Google Play Console, staged rollouts, closed testing
• 👥 Code review at scale — 290+ open-source PRs reviewed

Role Progression:

SDE 1, Android (Full-time) — June 2026 – Present

Android Developer (Internship) — Dec 2025 – May 2026

• Own the settings, products, expenses, and indirect-income features end to end — UI, domain, data, and network — in a GST billing app used by 5L+ Indian businesses. Also maintain notifications, thermal printing, and PDF generation flows.
• Migrated 16 feature modules and 100+ screens from legacy XML to Jetpack Compose, replacing fragment-held state with a multi-module MVI architecture — migrated flows now survive configuration changes that previously lost user data.
• Introduced Gradle convention plugins via a build-logic module, centralizing build configuration and reducing build-script duplication by 80%; new feature modules now start with almost no build setup.
• Refactored features out of a monolithic app module into independent feature modules using Kotlin, Coroutines, Flow, Hilt, Retrofit, and Room.
• Took over an unattended Crashlytics backlog and resolved 50+ production crashes and customer-reported defects; new reports now ship fixed within roughly 48 hours on a weekly release train. App maintains 99.8% crash-free sessions.
• Own Play Store releases through Google Play Console — versioning, staged rollouts, and release tracking.
