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 FLARE — Bold Basketball Courtwear
FLARE — Bold Basketball Courtwear Landing Page 🏀💗 FLARE is a fashion-forward sportswear landing page concept created for a basketball brand that wants to stand out both on and off the court. The idea was to move away from the typical dark, aggressive visual language of performance sports and build something more expressive, editorial, and lifestyle-driven. The hero combines oversized typography, soft pink tones, high-impact imagery, and product-focused storytelling to give the brand a strong identity from the first screen. The experience was designed around: • a bold campaign-style hero that immediately introduces the attitude of the brand; • strong visual hierarchy that keeps the product and athlete at the center; • an editorial layout inspired by fashion campaigns rather than traditional sports e-commerce; • clear navigation between new drops, courtwear, accessories, and brand stories; • a responsive mobile experience that keeps the same visual energy on a smaller screen; • prominent purchase CTAs without losing the premium campaign feel. The result is a sportswear experience where performance meets fashion — energetic enough for the court, but distinctive enough to build a lifestyle brand around it. ✦ Would you play it safe or PLAY BOLD? 🏀

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.
