Watching

Rewatching The Office, again. Long, I know — that's what she said.

Mobile apps built to ship — and keep shipping.

I am a mobile developer with 4+ years of experience designing and deploying Android and iOS applications using Kotlin, Jetpack Compose, and modern architectural patterns. I enjoy turning complex technical requirements into maintainable mobile systems that perform well in production and remain easy for teams to extend.

My work has spanned reactive interfaces, online-offline data flows, Firebase-backed mobile services, iOS feature delivery, and IoT communication using USB and LoRa. I am especially interested in solving problems where mobile software has to handle real-time device data reliably.

4+ Years Experience
4 Side Projects Shipped
60+ Locales Supported
2 Native Platforms

Personal apps shipped solo to the Play Store. Many more shipped through day-job work.

01 In Production

Bolt

Power Tool Shop Management

A complete business-in-a-box Android app for Indian power tool shops — managing rentals, repairs, inventory, customer CRM, and financial tracking with offline-first reliability.

Kotlin Compose MVVM + Hilt Local-first Room Firestore CameraX Play Billing AdMob
9 Entity types — rentals, repairs, inventory, CRM, bookings, transactions, sales, notifications, brands
Problem

Shop owners relied on paper registers — no digital solution existed for India's power tool rental market with offline support.

Key Feature

Community-driven suspicious contact registry — users report risky customers with categories (SCAM, STOLEN_GOODS, DAMAGE_THEFT), severity levels, and evidence. An auto risk-scoring algorithm protects shop owners against repeat fraud across the community.

02 In Production

Hydra

Smart Water Intake Tracker

A gamified hydration tracking app with an animated Canvas-drawn water wave UI, XP and leveling system, streak tracking, and weather-adaptive daily goals that adjust based on outdoor temperature via OpenWeatherMap and GPS.

Kotlin Compose Clean Arch Hilt Room Google Drive Health Connect 60+ Locales AdMob Play Billing
60+ Language locales — full localization across global markets
Problem

Users needed a habit-forming hydration tracker that adapts to their environment and keeps them engaged beyond simple logging.

Approach

3-layer animated sine wave progress indicator, dual reminder system (WorkManager + AlarmManager for doze-proof delivery), weather-based goal adjustment, and Google Drive backup.

03 Closed Testing

ZenTask

Gamified Productivity Suite

An RPG-style task manager with 100 rank tiers across 11 titles (Zen Initiate through THE ZENITH), built-in Pomodoro timer with 4 presets, task dependencies, recurring tasks, and Google Drive cloud sync.

Kotlin Compose Clean Arch Hilt Room Google Drive FCM WorkManager Play Billing
100 Rank tiers — Zen Initiate through THE ZENITH with quadratic XP engine
Problem

Standard todo apps lack the motivational mechanics needed to sustain long-term productivity habits.

Approach

Quadratic XP engine with streak multipliers, spring-physics animations, task dependencies, swipe-to-delete, multi-filtering, and Pomodoro focus mode with 4 presets.

Stack

Kotlin, Jetpack Compose, Material 3, Clean Architecture, Hilt, Room, Google Drive API, Firebase Auth + FCM + Remote Config, AdMob, Play Billing, WorkManager, 7 locales

04 Open Source

AuraSpend

Privacy-First Expense Manager

A world-class, privacy-first expense manager for Android 16 with smart bank message classification via SMS regex parsing, Material 3 expressive UI, Canvas-drawn charts, per-category budget tracking, recurring subscription management, and Google Drive backup.

Kotlin Compose Clean Arch MVI Room Google Drive Canvas Charts SMS Parsing Play Billing
100% Open source — Apache 2.0, no telemetry, no ads, no servers
Problem

Existing expense trackers either send data to the cloud, clutter the UI with ads, or lack Indian bank SMS parsing for automatic transaction logging.

Approach

Privacy-first with zero server dependency — all data stays on-device with optional Google Drive backup to a hidden app folder. Regex-based SMS classification supports HDFC, ICICI, SBI, Axis, Kotak, and more. Canvas-drawn charts with no external dependencies.
