Jan Duras

Hi, I'm Jan Duras

Creating since 8. Built taste, passion, and strong proof. Five years on high-stakes software including anti-doping systems used at Olympic and FIFA-level events. Google-certified in UX design. Now building through Durasius with the same promise.

A life-long passion for doing things not just to be OK or make profit, but done and built exactly as they should always have been. Nothing ships broken, confusing, or half-trusted — on my watch.

What people say after working with me

“He probably knows this product better than anyone else on the team.”

CTO (Chief Technology Officer)MODOC — Anti-doping done right.

…later I was asked to introduce MODOC to every new team member.

“With Jan in the MODOC team, we were able to achieve high-quality results in a very short time.

Jan has the skills to contribute to basically all parts of an end-to-end development process. Bringing in aspects and ideas in the brainstorming phase, proposing mockups of future designs in literally no time, reacting to changes and challenges with new creative proposals, and adding value anywhere and anytime in the value chain make him a key player in every marketing campaign or product design.”

“Jan brought a high level of design expertise, ownership, and creative thinking that made an immediate and lasting impact on our product. His work was consistently thoughtful, user-centered, and polished—he was never just designing screens, but solving real problems with clarity and purpose.

His contributions brought a strong visual identity and intuitive user experience that supported our business goals. Jan has the ability to balance visual aesthetics with usability, while always being open, communicative, and easy to collaborate with. Having Jan on board raised the overall quality of our product and team.”

Marek KocianCEO @ CANNYPACK (company developing MODOC).

“I have worked with Jan for many years, and beyond being colleagues, we have also built a friendship that could not exist without trust. What I value most about him is not only that he is highly skilled at what he does and has a truly broad range of abilities, but also that he can become genuinely passionate about a project when he believes in its success. In business, that is an invaluable quality.

He excels in web design, as well as working with graphics and video. At the same time, he shows talent in practically any creative field, including branding, marketing, and business strategy.”

The story

How I got here

Not a résumé in order. The turns that taught the standard — from making things at eight to shipping work that has to hold up.

Note: Durasius s. r. o. (Durasius) was incorporated in 2024, but there was real work long before it.

  1. 2011–2017

    Age 8–14

    Curiosity became craft

    Self-taught creative — photography, video, first games in GameMaker and PowerPoint, first HTML/CSS site. The habit of making things started here.

  2. 2017–2023

    School years

    Freelance, for real clients

    Brand identity, video, and web design while still in school. Co-founded and shaped the brand for TechGuru SK/CZ — then rebuilt their site in Next.js.

  3. 2020–2023

    Still in high school

    Olympic-grade QA

    Joined MODOC as a QA specialist on anti-doping software used at the Olympic Games and major international events. Wrote and managed 1000+ test cases. Post-release bugs dropped hard.

  4. 2023

    After high school

    Full-time, then product

    Went full-time in QA the week school ended. Within months, moved into Product Design & Marketing for MODOC.

  5. 2023–2025

    MODOC & CANNYPACK

    Design that shipped

    Led product design end-to-end — UX, brand, dashboards, onboarding. Multiple successful releases. Direct praise from execs and clients.

  6. 2025

    A company of my own

    Founded Durasius

    Partially left to build my own studio and holding company — products and systems that solve real operational problems.

2026–now

Under Durasius

The standard

The standard doesn't change

I've worked across quality assurance, product design, UX, and communication. The lesson has stayed the same everywhere: details matter. A confusing flow, an untested edge case, a website not looking and feeling on point and underselling the company — these are all the same problem wearing different clothes. I notice them. Then I fix them.
