Cover image for SKIN.ai — AI-Powered Skincare Routine

SKIN.ai — AI-Powered Skincare Routine & Skin Diary App 💗✨ SKIN.ai is a playful BeautyTech mobile app concept designed to make skincare tracking feel more personal, visual, and engaging. The experience combines structured routines, skin journaling, educational content, and an AI-style assistant that helps users reflect on daily skin changes without making the product feel overly clinical. The visual direction uses soft pinks, bold red accents, editorial typography, and expressive imagery to create a distinctive beauty-focused interface. Special attention was given to: • morning and night skincare routines with clear step-by-step tracking; • a skin diary that encourages users to log changes and build consistent habits; • AI-style guidance through a friendly assistant experience 🤖; • educational skincare content integrated into the product journey; • interactive reflection and gamified elements that make daily check-ins feel more engaging; • clear product logging and routine overview screens; • a strong mobile-first visual system designed to feel modern, expressive, and easy to use. The result is a BeautyTech experience that turns skincare routines into a more engaging daily ritual — blending functionality, education, and personality in one mobile product 🌸 Looking to create a mobile experience for your beauty, wellness, health, or AI-powered product? Let’s build something users actually enjoy coming back to 💫

Cover image for Love Tap — Telegram Mini

Love Tap — Telegram Mini App for a Dating Tournament Bot 💜 We designed a playful, gamified Telegram Mini App for Love Tap — a dating-themed bot where users vote, bet, and compete in a bracket-style "tournament" to pick the winning match for a featured bachelor. 🧩 The design leans into a bold, candy-purple aesthetic with glossy 3D character avatars and tactile UI elements, turning a simple voting mechanic into an addictive, game-like experience native to the Telegram environment. Special attention was given to: • onboarding flow that explains the concept in three clear steps; • tournament bracket UI showing live vote counts and betting status; • points and wagering system with a leaderboard for competitive engagement; • profile and stats screens tracking balance, top picks, and history; • consistent purple gradient and 3D-avatar art direction across every screen. A fun and highly engaging digital experience designed to maximize daily returns and social sharing — built to feel native inside Telegram while standing out visually from typical bot interfaces. Looking to design a gamified app or Telegram Mini App with strong visual appeal and sticky engagement mechanics? Let's build something impactful together!🚀

Cover image for Today I want to share

Today I want to share something important to me ✨ I’ve launched an app for people who travel with family or friends — and know the struggle: dozens of links saved in chats that are impossible to find when you actually need them. With this app you can: • save places for your trips in one space • share them with others • plan together without the chaos of messengers It also includes an idea generator that suggests nearby places to explore, showing interesting spots by category based on your location. Perfect for those moments when you want to do something new but don’t know where to start. This project is especially meaningful to me because I built it using Claude Code. I used to work as a UX/UI Designer, but my role has evolved significantly. Thanks to new technologies, I’ve been able to expand my scope — from design to building a full product. It feels like a new level of freedom — when an idea can turn into a real tool faster than ever. I will happy to see you as my new user: https://apps.apple.com/pl/app/ourmap-save-places-trips/id6762603048 I’d love to hear your thoughts 💬

Cover image for We live in interesting times,

We live in interesting times, a year ago I couldn't even imagine that it would be possible to create a product without Figma, and code without a Developer. I am a UX UI designer, but my workflows will never be the same as they were literally half a year ago. In a month, I created two products with Claude Code, and realized that I am no longer interested in working with design itself. I don't know how my profession will change in the near future, but I feel big changes in myself 😄 By the way, this is my product in the development process at the moment, Localify - helps to localize products, and also localizes App Store Listing, taking into account all the store's requirements for symbols

Cover image for I’m currently developing OurMap — a specialized

I’m currently developing OurMap — a specialized tool designed to end the "where should we go?" frustration in group travels. Great locations get lost in chat histories. Links from Instagram, Telegram, and TikTok are scattered, making it impossible to coordinate on the spot. I’m building this as a "Solo Studio," leveraging AI to handle everything from Swift architecture to high-fidelity 3D assets. It’s a testament to how AI-driven development can turn a complex social idea into a polished MVP in weeks. It's really interesting because a month ago I was only designer, who could only design interfaces, but now it's fulfilled experience. Status: Finalizing the UI and real-time sync. Launching soon.

Cover image for A quick look through the

A quick look through the landing page layout for WAct 👀 🔗 Explore the full case study on Behance: WAct on Behance (https://www.behance.net/gallery/253815513/WACT)I believe most founders know the frustration of running paid ads that bring plenty of clicks, but zero qualified leads. The WAct team needed more than just a visually appealing layout, they needed a site that immediately explains how their platform connects ad spend to actual WhatsApp conversations. What I focused on here: Clear hero section: Addresses the pain point right away by showing how ad budget converts directly into real customer chats. Logical flow: Guides the reader step-by-step from the main problem to key analytics, integrations, and the contact form without any fluff. Approachable visual style: Combines warm editorial tones and sharp typography so complex B2B data feels straightforward and easy to digest. For me, combining UI architecture with clean technical implementation is what transforms a site from a static showcase into a high-converting product tool. I'm currently open to new project opportunities and collaborations. DM me if you have a project in mind!

Cover image for When designing WAct, the main

When designing WAct, the main challenge was to make complex analytics feel calm, approachable, and actionable. Marketing tech platforms often suffer from visual noise: endless charts, aggressive contrast, and buried data. For WAct, I took an editorial SaaS approach: Visual Hierarchy: Kept the primary metric cards (CPL, Lead Quality Score) instantly readable at a glance. Warm Aesthetic: Used a soft, olive-green gradient backdrop paired with editorial typography to make the brand stand out from generic blue dashboard templates. Dashboard Logic: Structured the flow so users can track multi-channel ad conversions straight into WhatsApp chats without getting overwhelmed. Building a complex B2B platform or analytics tool? Let’s connect and create a seamless UI/UX for your product. 🔗 Explore the full case study on Behance: Check out WAct on Behance (https://www.behance.net/gallery/253815513/WACT)

Cover image for When selling a premium service,

When selling a premium service, mentorship, or high-value framework, a generic template fails to convey the true depth of your offer. The challenge I solved here was translating a multi-stage methodology into an intuitive, high-converting digital experience, built natively on Webflow. By combining an editorial landscape aesthetic with modern, scroll-triggered interactions, I turned an abstract concept into a seamless visual journey. Methodology Visualized: I designed custom interactive nodes (Relaxation → Attention → Motivation) that walk users step-by-step through the core process. Webflow Build: I developed the full site on Webflow with clean HTML/CSS architecture, fluid animations, and fast load speeds. Editorial Identity: I paired a warm color palette and subtle grid architecture with vintage illustration elements to build immediate authority. Flexibility: I set up a clean Webflow CMS structure so you can easily update content without touching code. Need a custom site that clearly communicates the value of your framework and converts visitors into clients? Send me a message and let’s discuss your project!
