Design systems specialist
Built and migrated systems at enterprise scale — components, tokens, governance, and contribution models. Not just UI libraries.

ABOUT
Hello — I'm Oleksandr Myroniuk.
Product designer for the work that's harder than it looks.
I design products where the real complexity sits underneath — design systems, enterprise tools, iGaming platforms, and complex UX problems where clarity and scalability matter more than surface polish. I've shipped at REWE Group across multiple enterprise products and built a multi-vertical crypto iGaming platform end-to-end. Clients hire me because design and delivery don't get lost in translation.

BACKGROUND
Designer with an engineering foundation.
I've spent over a decade working across enterprise tools, iGaming, fintech, and e-commerce — consistently chosen for complex UX problems where clarity and scalability matter more than surface polish. My work shows up at scale: enterprise products at REWE Group, multi-brand design system contributions across UNIFY, and a multi-vertical crypto iGaming platform built end-to-end as the only product designer.
Alongside design, I have a software development background — Bachelor's and Master's in software engineering. That foundation shapes how I design: I understand implementation realities, component architecture, and how design decisions behave once they ship inside a real product. Clients hire me because design and delivery don't get lost in translation. I care less about surface polish and more about whether a product is clear, adopted, and maintainable two years after I leave.
SERVICES
What I'm hired to do.
Six engagement types, all rooted in the same approach: structured product thinking, scalable systems, and craft that survives implementation.
Design system architecture
Building design systems from scratch — components, tokens, patterns, contribution model, Figma libraries, and governance. The product infrastructure teams need to scale without fragmenting into seven inconsistent UIs.
Design system migration
Moving products off legacy UI or older systems into modern, scalable foundations. Component mapping, audit, high-fidelity adaptation, gap identification, and team enablement so the migration sticks.
Enterprise product design
End-to-end UX/UI for internal tools, admin platforms, and data-heavy enterprise interfaces where clarity has to survive business rules, edge cases, and scale.
iGaming and conversion UX
Performance-driven product design for online casino, crypto casino, and sportsbook surfaces where speed, trust, regulated flows, and measurable conversion outcomes matter.
Complex UX platforms
Product design for multi-product ecosystems — user roles, permissions, states, edge cases, and structural UX that only reveals itself once the product hits real scale.
Senior design partnership
Senior-level product design support without a full-time hire — design reviews, UX architecture audits, design system strategy, component thinking, mentoring, and unblocking product work.
PROCESS
A structured partnership — from first call to shipped product.
What clients actually get when they bring me in.
Align before pixels
Discovery and alignment first. I work with stakeholders, Product Owners, and Business Analysts to understand the real problem, business constraints, and success criteria before opening Figma. Most projects fail at this step. I don't.
Structure the product logic
Information architecture, flows, states, dependencies, user roles, and edge cases mapped before high-fidelity work begins. Interfaces should reflect real product complexity, not hide it poorly.
Design with reusable systems
Components, patterns, and design decisions built to scale beyond the first screen. I design for the third year of the product, not the launch demo.
Validate, ship, support
User testing, analytics review, and product feedback drive what ships — not assumptions or personal taste. I stay involved through handoff and implementation, so the intended experience reaches production, not just the design file.
ENGAGEMENT
Flexible ways to bring me in.
Project-based
Fixed scope, fixed timeline. Ideal for design system builds, redesigns, migrations, and bounded product work. Typically 2–6 months.
Ongoing retainer
Monthly engagement for continuous product design or design system work. For teams that need senior design capacity without hiring full-time.
Strategic advisory
Short-form senior input — design reviews, UX architecture audits, design system strategy, and mentoring. Hourly or session-based.
Team augmentation
Embedded work alongside your existing product and engineering team. Sprint-based or milestone-based, tailored to delivery rhythm.
Currently open to new projects.

Working on something complex?
If you're building enterprise tools, design systems, or a complex product that needs senior product design from structure to UI — let's talk. I'm currently open to new engagements.
