Brand Identity and UI/UX Designer for AI-Native CRM
Illia and Cosmos team have delivered everything I asked on time and within the budget. The most important aspect for me in this project was to understand my ideas / needs and professionally translate them into a polished UI and when needed challenge things.
They've overachieved this also being very responsive.
Collaboration is super smooth and they're super kind, which is also important for me. (Important to work with people you enjoy collaborating with).

I'm a UI UX Designer running a product design studio that partners with SaaS, FinTech, MedTech, CyberSec, and EdTech founders who need their product to feel obvious, not just look good - we succesfly delivered 500+ projects.
💡 What I bring to your product as a UI UX Designer:
✔️ As a UI UX Designer, I have designed 2,500+ screens and 70+ user flows for a B2B inventory SaaS platform, turning a messy logistics tool into one clean system that teams actually enjoy using.
✔️ As a UI UX Designer, I lead full product design cycles: UX research, wireframing, high fidelity UI, and design systems that developers can actually build from. As a UI UX Designer, I have earned a Red Dot Award for our own studio site, plus Awwwards Site of the Day and CSSDA recognition on client projects, including an interactive encyclopedia site that reached 1.5 million views.
✔️ As a UI/UX Designer, I focus on SaaS Design for complex dashboards. I designed an AI native CRM with a calm, zero setup feel, an omnichannel SaaS platform for opticians with 15+ modules and a full design system in dark and light mode, and a cybersecurity operations platform where every screen had to make a technical product feel manageable. As a UI UX Designer, SaaS Design is where I spend most of my time, because that is where clarity matters most and where a confusing dashboard costs a client the most support tickets.
✔️ As a UI UX Designer, I also handle Web Design end to end, from marketing sites to full platforms. I designed a 20+ page corporate Web Design project for a customer support outsourcing company, a 3D storytelling careers page for a gaming studio, and an award winning promo site for an AI company built around an interactive Bullshitometer feature. This Web Design work runs on Webflow, WordPress, or React, depending on what the client's web developer team needs for handoff.
✔️ As a UX Designer, my Mobile App Design work includes AIM, a two sided fitness coaching marketplace live on the App Store, and a fasting and social app for iOS and Android built with a full design system in Figma. Both needed onboarding simple enough that people would actually open the app the next day.
✔️ As a UI UX Designer, Brand Identity is part of most projects I take on. I have built visual identity systems for AI HR startups, sleep tech brands, and a private members club, going from logo concepts and typography through full brand guidelines a team can run with.
🎯 The measurable project’s results, as a UI UX Designer:
▪︎ UI UX Designer for a national EdTech platform (React based): -38% support requests, +24% monthly active users after launch.
▪︎ UI UX Designer for a Non-Profit adoption platform: +35% adoption rate, 85% of requests shifted to the new site.
▪︎ UI UX Designer for a MedTech desktop app: clinical software for 3D printed orthopedic devices, built for guided and advanced user modes.
▪︎ UI UX Designer for a Healthcare e-commerce platform: subscription flows and patient onboarding designed across 300+ hours of work, including photography and animation.
⚡️ Where I have worked as a UI UX Designer:
⎼ SaaS Design and dashboard design for B2B, AI native, and CyberSec products.
⎼ UI UX Designer for FinTech and CyberSec platforms where trust has to be visible on screen one.
⎼ Web Design for EdTech, research, and government backed platforms, including a bilingual OECD research website and a gamified multi persona platform for students and teachers.
⎼ Mobile design for health and wellness apps on iOS and Android.
⎼ Brand Identity and graphic designer work for AI startups and premium lifestyle brands, from logo concepts to full guidelines.
⎼ Web Design for GameDev and Web3, including career pages, staking platforms, and character driven NFT brands.
⎼ Product designer work for e-commerce, including a healthcare e-commerce and subscription website, plus Shopify focused work for retail brands.
⚒️Tools and process, as a Figma designer:
I build wireframes, interactive prototypes, and design systems with components and variables ready for handoff. I work across Webflow, WordPress, and React, and follow Apple Human Interface Guidelines and Material Design for mobile platforms. Every project starts with UX research and user flows, moves through wireframes and high fidelity UI, and ends with a design system a developer can build from without guessing.
