What we have achieved so far

Websites built end to end — plus product design, QA and marketing. Live in the real world.

Website, promo video, product design & QA

MODOC website homepage, designed and built by Jan Duras

MODOCWebsite and promo video built · QA, product design and marketing on the product (opens in a new tab)

Software used at Olympic and FIFA-level events all across the world.

  • “Johnny, you are a f***ing wizard 😃 I’m absolutely blown away by both, the website and the video!!”

  • “Awesome, awesome, awesome 👏”

  • “Thank you, thank you, thank you! AMAZING work on all aspects, website, video(s) and app design! I couldn’t be happier”

The situation

MODOC is specialised anti-doping software used at Olympic and FIFA-level events. As the product carried serious operational weight, the public face had to match that seriousness for international buyers and partners.

Why it mattered

When a specialised B2B product looks thinner than the work behind it, prospects and partners cannot quickly judge whether it is credible enough for regulated, high-stakes environments. Clarity and trust become the bottleneck—not the capability of the software.

What we changed

  • I rebuilt pwc-modoc.com as a full brand overhaul and website so the product’s scope and seriousness could be understood without prior insider knowledge.
  • I shaped a stronger visual identity and a clearer page structure around what the product actually does and for whom — not a generic software template. I also made the promo film.
  • On the product itself I did quality assurance (three years), product design across the backoffice and DCO mobile app, and marketing — release-note standards and marketing creative — so the public site and the product spoke with one voice. I did not build the MODOC platform.

The result

MODOC now has a live international website and brand presentation that carries the weight of software used at major global events. The client team’s reaction to the website and video speaks for itself.

CANNYPACK website homepage, designed and built by Jan Duras

CANNYPACKSoftware company (opens in a new tab)

Software company developing MODOC, LEAP and other products.

  • “Great work. A big thanks!”

  • 👏

  • “A strong, modern visual identity and intuitive user experience that supports our business goals.”

  • “Ability to balance visual aesthetics with usability.”

The situation

CANNYPACK is a software company based in Bratislava, Slovakia — home to MODOC, LEAP and other products — that needed a coherent market-facing company site.

Why it mattered

A product studio that ships serious software still loses trust if the company page cannot explain who they are, what they build and why a buyer should talk to them. The website has to carry both the company and the product story.

What we changed

  • I redesigned and developed cannypack.com with a cohesive visual identity and a clear path through their services and products.
  • I treated the site as the public frame for a product company — not a brochure bolted onto unrelated work — so visitors could connect the studio to MODOC, LEAP and the wider offer.
  • I stayed close to executives, product owners and delivery teams so the website matched how the company actually works.

The result

CANNYPACK has a live company website that presents the studio and its products as one coherent destination. Client feedback credited a strong visual identity and clearer overall product and team quality; no lead or revenue metrics are claimed here.

Website, product design & marketing

LEAP website homepage, designed and built by Jan Duras

LEAPWebsite built · product design and marketing on the ERP (opens in a new tab)

Software custom-built for consultancies in the DACH region.

  • “The site looks genuinely amazing.”

  • “Johnny, I'm impressed.”

  • 🎩⬇️

The situation

LEAP is B2B software custom-built for consultancies in the DACH region that needed a strong digital presence accompanying the launch of the product.

Why it mattered

Specialised software for a defined regional audience fails quietly when the website cannot explain the category, the buyer or the difference. It also needs to look and feel proper, evoking trust and the actual capability of the product to its potential customers.

What we changed

  • I built a custom leap-erp.com with a brand overhaul so the product’s audience and purpose read clearly to DACH consultancy buyers.
  • I structured the site around what consultancies need to understand first — not a generic ERP template — and supported it with SEO, performance and analytics foundations.
  • On the ERP itself I did product design (including dashboard and navigation experiences) and marketing, so the site I built and the product direction stayed aligned. I did not build LEAP.

The result

LEAP has a live product website aimed at its DACH consultancy audience, with a clearer public presentation of a specialised B2B offer. Client reaction to the site was strongly positive; measured commercial outcomes are not claimed here.

Brand overhaul & Complete website

TechGuru SK/CZ website homepage, designed and built by Jan Duras

TechGuru SK/CZMedia company (opens in a new tab)

Media company producing news articles and reviews from the world of tech, science and gaming.

  • “Johnny, the site is crazy good!”

  • “Simple, modern — looks like no other competition's site.”

The situation

TechGuru SK/CZ is a media company covering tech, science and gaming. I stood at the founding in 2017 and led brand, site and marketing from the early WordPress presence through later rebuilds. Peter Vnuk is the founder. As the previous site was built mainly on a WordPress template, over time it became dated and hard to adjust to the company's future vision.

Why it mattered

A content-heavy media brand that looks like every other tech outlet disappears in the feed. Distinctiveness is not decoration — it is how the audience recognises the source and keeps returning.

What we changed

  • I shaped the brand identity and creative direction from the original logo system, then rebuilt the site as a modern Next.js platform with stronger SEO, performance and reading UX.
  • I kept the brand’s distinctive meme-led marketing voice in the system rather than flattening it into a generic news template. The goal was simple — a beautiful, fast, exceptionally great-to-use website built on a modern stack and much more attractive to readers compared to the competition which had mainly dense, hard to orient around interfaces.

The result

TechGuru remains live at techguru.sk with a recognisable identity and a content-ready website. The founder’s own line on the result: it looks like no other competitor’s site. The readers themselves also complimented the design and user experience once getting their hands on the product.

What people said about our founder

Trusted to raise the quality.

“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.”

“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.”

“Jan brought a high level of design expertise, ownership, and creative thinking that made an immediate and lasting impact on our product. His work in Figma was consistently thoughtful, user-centered, and polished — he was never just designing screens, but solving real problems with clarity and purpose. Thanks to his contributions, we launched the company and product web with a strong, modern visual identity and intuitive user experience that support our business goals. Having Jan on board raised the overall quality of our product and team.”

“Excellent work on the MODOC project! The design skills, the creativity and the dedication of Johnny brought great value to the platform. It has been a pleasure to work with someone so committed and detail-oriented; an essential part of the team.”

Founder

Jan Duras

Founder of Corsius · CEO of Durasius

Jan Duras (Ján Ďuraš) has been making things since he was eight — photography, video, his first games, his first HTML and CSS. Through his school years that turned into paid brand, video and web work. In 2017 he stood at the founding of TechGuru SK/CZ — brand, site and marketing. Peter Vnuk is the founder. That work now runs through Durasius.

Still in high school, he joined MODOC as a QA specialist on anti-doping software used at the Olympic Games and FIFA-level events. Over three years he wrote and managed more than 1,000 test cases and post-release bugs dropped hard. He went full-time the week school ended, and within months moved into product design and marketing on the same product.

From 2023 he led design end to end for MODOC and CANNYPACK — UX, brand, dashboards, onboarding — and as an external partner built the company websites for CANNYPACK, MODOC and LEAP ERP. He did not build the MODOC platform or the LEAP ERP: he tested them, designed for them, and gave them a public face that matched the work behind them. He holds the Google UX Design Professional Certificate (2024).

He incorporated the company as The Whizziest, s. r. o. on 18 October 2024. In October 2025 he went all in on it — full commitment, not a rename. The commercial register renamed the company Durasius on 10 March 2026; the former legal name The Whizziest, s. r. o. was valid until that date (platné do: 10.3.2026). Everything he ships now runs through it, and the standard has not changed since QA: a confusing flow, an untested edge case and a website that undersells the company are the same problem wearing different clothes. Notice them, then fix them.
