Résumé

About Dhruv Patel

I’m Dhruv Patel (known online as DearDhruv), a Lead Android Engineer, Android Architect, and Android Artist based in India. With 15+ years of experience across mobile engineering, I focus on native mobile systems, high-performance architecture, hardware integration, and running local AI models directly on consumer devices.

Currently, I serve as a Lead Android Engineer at IMPACT Commerce, where I work on digital commerce applications, custom Android OS touch hardware, and point-of-sale integrations.

Beyond enterprise systems, I design and build independent open-source products. Two projects where I’ve documented my work in detail are AI Playground, an offline-first mobile workstation for running local LLMs and diffusion models, and VelociHue, a fast-paced arcade action game engineered in Kotlin Multiplatform and Compose Multiplatform for Android and Android TV.

🛠️ How I Approach Engineering

I prefer working on problems where software directly meets hardware limits. A few principles that guide how I build:

1. Build for Real Device Constraints

Mobile devices have hard thermal ceilings, volatile memory budgets, and unpredictable battery drains. When building AI Playground, running inference directly on a phone meant accounting for vendor Vulkan driver segmentation faults. Rather than pretending mobile drivers never crash, I moved inference into a defensive fork() child process sandbox with a 3000ms watchdog loop. If a driver crashes, the child process is terminated with SIGKILL without taking down the user’s UI.

2. Prefer Local Processing Where Practical

Cloud services are convenient, but keeping compute local protects privacy, eliminates round-trip network latency, and ensures applications work when connections fail. Running on-device LLMs (via llama.cpp and LiteRT) and keeping documents in a local SQLite database ensures personal data never leaves the device.

3. Share Logic Without Sacrificing Native Feel

In Kotlin Multiplatform, I favor sharing deterministic core logic (state stores, persistence engines, and game loops) while respecting each platform’s native strengths. In VelociHue, Android TV navigation uses native D-pad focus semantics, iOS runs a SwiftUI host, and Android uses Jetpack Compose, all sharing a single deterministic physics loop.

4. Hardware Integration Demands Defensive State Machines

Working with physical point-of-sale peripherals (receipt printers, payment terminals) taught me that hardware state can disconnect at any millisecond. I design hardware abstraction layers with isolated IPC channels, timeout fallbacks, and defensive reconnection state machines.
