Hazel Widiantoro is a product designer based in Stargard, Poland who takes products end to end: defining the roadmap, prioritizing features, and making sure what ships meets both user needs and business goals. Hazel founded Draculinary, a point-of-sale and QR table-ordering system for restaurants and cafes, now in a live pilot in Bali. Next up is ReHub, an anonymous social platform that helps people having a way to socialize, with mobile-first design and his favorite recipe to deliver through gamification.
It all started with irritation at bad interfaces and experience using government websites and apps, and a habit of sketching what a better one would be. Outside of design, he is a restaurant and cafe surfer, drawn to art, technology, human behaviour, and problem solving.

June 2026
Draculinary
Founder & Full-Stack Developer
Founded a SaaS company in Bali with a co-founder: a point-of-sale and QR table-ordering system for restaurants and cafes. I handle the whole product, from research and design to development, and it is now in a live pilot at a cafe in Bali.
ReHub
UI / UX Designer
ReHub begins in August 2024, it is a project that pushed my creativity and innovation through gamification of a digital interaction. I’ve made a prototype to be a collector of avatars with quests not only limited to the digital world, but some require real-world action like hosting or joining a gathering, doing charity, and so on. I’ve also made a way for users to keep retention to open ReHub high by rewarding them with various consumable items and incentivizing more visits each day; the more rewards they get up to a certain point. Push further 1:1 chat to be more active through an isolated quest list in their chat.

Keeping up with Boring Notch’s design theme as a seamless window.

FAQ
What kind of products do you work with?
Mobile apps, web apps, e-commerce, POS, menus, personal or community websites, analyzing existing systems for a clean and efficient user experience. Anything with an interface people have to move and interact with. Different fields, same underlying question: is this clear, and does it feel like you?
What does your process look like?
Every project starts with your goals, what you want people will feel and do. From there I look at how it works today and where clarity get lost. Shape the flows, design the interface, and actually build it like a Swiss Army knife. You see the work at the end of each stage, so the direction is agreed before it's built on.
I only need a few pages or features added, can you do that?
Yes. Not every product needs a redesign. I can work inside what you already have, follow the design system that's there, and add what's missing so it looks like it always belonged.
What do you need from me to get started?
A clear and detailed brief is ideal: your goals, who the product is for, and any technical requirements like format, platforms, or tech stack. References, moodboards, or brand guidelines are welcome, though not required. If the direction isn't fully formed yet, shaping it together is one of the fun part of the work.
What does it cost?
I work hourly, which keeps things transparent and let us adjust as we go. If you'd rather have one number to plan around, I'll quote the full scope once we've defined it. If we rather have a period of contract work, we can do that too. I can work with your existing team or independently, and I can work remotely or on-site (EU).
Do I need to sponsor your work visa?
For remote work, no. For on-site work in the EU, yes. I can't work on-site in Poland or Berlin, Germany without sponsorship, while I can work remotely from anywhere in the world.
What are you doing in Poland, why Poland?
I applied for a Polish visa in 2024 and almost forgot about it. By the time it was approved, two years had passed and I was running my own startup in Bali. I decided to take the chance anyway, splitting responsibility in Bali to co-founder while I'm taking responsibility to find clients in Europe. My first plan is to keep building remotely and selling door-to-door my SaaS on evenings and weekends while working as any in Poland. I’m giving myself a shot for one year until July 2027, until my visa runs out, to find a better opportunity in Europe and to learn a new culture and language along the way. For now I work in metal preparing industry as manual labour in Stargard, Poland, which at least it's what lets me stay here with work visa. What I’m looking for is a chance to proof my skills and having an opportunity to be surrounded with supportive environment encouraging innovative and creative ways of doing. While getting sponsored to keep being in Europe. To answer the question, being here in Poland is a stepping stone to a better opportunity.
