Hey, I'm Gintaras. I help teams build digital products that make sense to real people, in real situations, with real stakes. And I deliver the full surface: research, UX, UI, design systems, and launch-ready UI code.
Over the last 10+ years I've worked with Fortune 500s, fast-growing startups, and everything in between — from Philips and Tax-Free.no e-commerce to enterprise tools for Medtronic and Adform. I design in code: components, interaction layers, design system tokens, all production-ready on the UI layer. What I design is what ships.
I've led redesigns that moved the needle. Like turning a clunky e-commerce platform into a +197% jump in revenue per user. Or building design systems that scale across 17 markets without losing clarity or accessibility.
My background? IT + MBA. My edge? I speak business and design fluently and I don’t waste time on fluff.
My background grounded in HCI. MSc IT Management, MBA. I speak business and design fluently.
I also write design specs for AI agents and MCP servers, structured constraints, brand rules, and accessibility guidelines that keep AI-generated UI coherent and on-brand from the first output.
If you're building something complex, and you need someone to make it feel simple and ship it — let's talk.
Brands I help succeed with world-class UX
Selected Work
Services
1. UX Strategy & Research
Stakeholder interviews,
Customer journey mapping,
UX audits,
competitive analysis,
persona development,
behavioral data (Amplitude, Hotjar, MS Clarity).
Research that understands real people in real contexts and feeds directly into design and code, not a slide deck that sits in a drawer.
2. Information Architecture & Interaction Design
navigation structures
content hierarchy
user flows
UX writing and microcopy
The structural thinking that makes complex products feel simple. Grounded in HCI principles and carried forward into coded prototypes where the structure can be tested for real.
3. UX/UI Design & Coded Prototypes
Scalable UI design systems & reusable component libraries
Clickable hi-fi prototypes for validation & stakeholder buy-in
Accessibility (WCAG) compliance
Components are real, states are real, interactions are real. Stakeholders test working software, not static mockups. What you validate is what ships.
4. Usability Testing & Optimization
Usability testing (remote/in-person) with key metrics (SUS, CES, time-on-task, error rate)
A/B testing, heatmaps & behavioral analytics
Conversion rate optimization (CRO) for e-commerce & SaaS
Continuous iteration based on user feedback & data
5. Design Systems in Code
Scalable, token-based design systems built as production-ready component libraries. Spacing, color, typography, and interaction patterns defined once and consumed directly by engineering. No translation layer, no drift between "the design" and "the build." Systems that hold across markets, brands, and teams.
6. AI-Ready Design Specs
Design constraints, brand rules, and accessibility guidelines structured for AI agents and MCP servers. When your team uses AI to generate or explore UI, these specs keep outputs coherent, on-brand, and WCAG-valid from the first generation — without manual cleanup.
7. Specialized UX Solutions
Enterprise UX & B2B SaaS solutions
E-commerce UX (checkout flows, product discovery, subscription models)
Healthcare UX (medical device interfaces, patient portals, prior authorization workflows)
Finance & insurance UX (quote flows, claims processing, dashboard design)
SEO & UX alignment for organic growth
