About
Engineering discipline with a product delivery mindset.
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.
Selected Work
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.
Shop owners relied on paper registers — no digital solution existed for India's power tool rental market with offline support.
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.

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.
Users needed a habit-forming hydration tracker that adapts to their environment and keeps them engaged beyond simple logging.
3-layer animated sine wave progress indicator, dual reminder system (WorkManager + AlarmManager for doze-proof delivery), weather-based goal adjustment, and Google Drive backup.

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.
Standard todo apps lack the motivational mechanics needed to sustain long-term productivity habits.
Quadratic XP engine with streak multipliers, spring-physics animations, task dependencies, swipe-to-delete, multi-filtering, and Pomodoro focus mode with 4 presets.
