Project Portfolio

IoT, BLE, & Hardware-Integrated Solutions

IoT-Based Grain & Warehouse Monitoring

Architected a native Android solution for large-scale farmers to visualize sensor arrays. Integrated real-time 3D models and responsive data charts with back-end predictive algorithms to proactively flag grain spoilage and manage storage unit lifecycles.

Android Native Kotlin IoT Sensors 3D Models

Pesticide Spraying Service & IoT Controller

Developed a high-performance, Offline-First mobility solution. Integrated a BLE-based GPS controller to govern physical spray mechanisms while accurately mapping location and spray metrics for operational validation. Optimized for low-network conditions caching data locally.

Kotlin BLE SQLite Offline-First

Smart Pen & Biometric Authentication Systems

Built a custom BLE communication layer to read and render real-time pen strokes from a digital Smart Pen onto paper. Successfully integrated biometric hardware SDKs via OTG to process encrypted Aadhaar-based KYC fingerprint verification directly on commercial mobile devices.

Java BLE Biometric SDKs OTG

Enterprise Field Force & Mobility Ecosystems

Farmer Services & Partner Ecosystem App

Delivered a unified, 'Ola-like' service-booking ecosystem tailored for Indian farmers, tractor operators, and logistics partners. Embedded real-time machine location mapping and integrated Razorpay for streamlined on-field collections.

Flutter Dart Razorpay Maps API

Field Force Management Suite

Designed and engineered a multi-tiered operations management suite for field managers and tractor technicians to monitor data created by Operators. Implemented strict SLA workflows, remote machine breakdown diagnostics, and expense logging.

Kotlin Java Geofencing WorkManager

Legacy Migrations & Community Initiatives

BYOD Enterprise Migration

Spearheaded the UI/UX and architectural overhaul of a core field-reporting tool, migrating it from tablet-specific formats to a highly responsive, device-agnostic mobile blueprint.

Android Native Java UI/UX Redesign

Community Welfare Application

Developed an end-to-end social coordination application supporting child protection movements, enabling secure user onboarding, pledge signing, and global campaign visibility.

Android Native Java Security

Personal Projects

Apps I design and build for learning and for fun — published on Google Play.

tables

A Flutter POS-style app for cafes to manage tables and live orders. Each table tracks dishes through Pending → Accepted → Completed states with running totals; a single tap generates the final bill, empties the table, and archives it to historic records.

Cafe Jukebox

A fully offline music jukebox for cafes and venues that runs on a single Android tablet. It builds a library from local MP3 files and hosts a local Wi-Fi server so guests browse songs and queue requests from their own phones — no internet, accounts, or ads. Requested songs can display the guest's name in the queue.
