LATEST TOOLS

Reliable utilities for power users

LogMaster Pro

System log analyzer tool

Android Tool • Sysadmin • Performance

A clean, dark-themed utility for developers to monitor system logs in real-time. Built with a focus on low memory overhead and lightning-fast search capabilities for complex debugging.

LogMaster Pro was born from a frustration with clunky mobile debuggers. We needed a tool that felt like a professional CLI but worked on the go. The interface uses a high-contrast palette of dark blue and teal to ensure readability during late-night maintenance sessions. Features include customizable regex filters, cloud-sync for log snippets, and a modular widget system for home screens. Every interaction is optimized for the Ukrainian power user who needs to manage remote servers directly from their smartphone. It is a testament to our belief that professional tools should also be beautiful and intuitive.

Neon Shift

Arcade Puzzle Game

Game Design • UI/UX • Mobile Visuals

A fast-paced, vibrant puzzle game inspired by retro-futurism. We combined addictive gameplay loops with a sophisticated visual style that stands out on the Play Store.

Neon Shift challenges players to navigate complex geometric mazes using rhythmic taps. The project focused heavily on fluid animation and haptic feedback to create a truly tactile experience. We developed a proprietary physics engine for the light trails to ensure the game runs smoothly at 120Hz on flagship devices. The result is a playful yet polished experience that appeals to both casual gamers and design enthusiasts in the Eastern European market.

UA Tracker

Inventory Management

Business App • Database • Logistics

A robust, offline-first application designed for local Ukrainian businesses to track assets across multipleUA Tracker was designed for resilience. Understanding the infrastructure challenges in the region, we built a synchronization engine that handles intermittent data connections with grace. The UI uses a strictly professional palette of deep blues and off-whites, prioritizing data density and clarity. We worked closely with local logistics visuals.

Opal came to me with a clear ask: their skincare line was gentle, effective, and ingredient-focused, but their visual identity felt generic and overlooked. I redesigned everything from the ground up, starting with a new logotype that felt softer and more considered. The photography direction emphasized natural light and minimal styling—no aggressive shadows or clinical backdrops. I designed a label system that worked across multiple product formats (bottles, tubes, jars) while keeping a unified look. Typography was kept
