Independent Android Developer

Building focused Android tools for real workflows.

I design and ship Android apps that solve practical problems: server monitoring, mobile utilities, automation helpers, and lightweight tools that stay close to the user's task.

Android engineering with product sense.

My work combines mobile UI, local data, release engineering, monetization, and the small details that make an app reliable after it leaves the IDE.

I build Android applications with Kotlin and Jetpack Compose, usually around tools, dashboards, and utility workflows where speed and clarity matter more than decoration.

Recent work includes DogServerLite, a lightweight server management app for monitoring SSH servers, and Clight, a flashlight utility for brightness control, energy-aware use, and emergency SOS signaling.

I care about shipping complete products: app identity, package naming, Firebase, Google Play Billing, AdMob, privacy policy, release builds, and Play Console readiness.

UI
Compose product interfaces Dashboards, lists, settings, dialogs, and responsive app flows.
REL
Android release workflow Signing, package variants, Firebase, Play Console, and publishing checks.
MON
Monetization integrations AdMob, Google Play Billing, remove-ads purchases, and policy-aware UI.
OPS
Operational utilities SSH workflows, command snippets, local state, diagnostics, and automation.

How I build.

I keep the path from idea to release practical: understand the workflow, build the smallest complete surface, verify on real artifacts, and prepare the store listing work early.

01

Define the job

Start with the user's workflow and decide what the first screen must accomplish.

02

Build the app path

Implement focused Compose screens, local state, data flows, and error handling.

03

Prepare release

Set app identity, Firebase, billing, ads, privacy policy, and release variants.

04

Verify the artifact

Build debug and release outputs, inspect generated config, and test the real package.
