Design & build — Matúš Kališ

Interfaces, cut and assembled.

Marketing sites, product surfaces and data tools. Some shipped to real traffic, some were directions a client didn't take. Both are here, labelled honestly.

Electric lime headline on deep navy with a dithered organic texture

Tharseo IT

Oracle Cloud partner selling into federal and enterprise. The largest build here — 32 routes, 133 components — held together by one rationed lime accent.

Next.js GSAP Lenis Shipped

Brown bear photograph with a large serif Slovak headline over it

LCI-SK

Large-carnivore conservation for Slovakia. Editorial photography up front, a genuine occurrence map over 3,600+ field records behind it.

Next.js Leaflet Bilingual Shipped

Institutional Slovak news site with a cattle photograph, green rules, and a ranked most-read rail

SPPK

Rebuild for Slovakia's agriculture and food chamber. Newspaper density, but edited: one lead story, then a rail that ranks everything else by readership.

Next.js Publisher Client rebuild

Dark violet product hero with a gradient headline and a phone mockup showing a live grammar correction

Vorex

AI English tutor. The hero doesn't describe the product — it performs a real correction, errors struck through in red, fixes in green.

Product site vorex.app Shipped

Black starfield page with a dot-matrix Atlas figure and a monospace headline

matuskalis.com

My personal site. Monospace throughout, a halftone Atlas holding up the world, and ornament borrowed from instruments rather than graphic design.

Personal Monospace Shipped

Charcoal hero with a large white headline and a single bright blue button

AI Consulting Microsite

One claim, one button, one accent colour on the entire page. Same person as the personal site, aimed at a completely different reader.

Microsite Own brand Shipped

Coral-on-charcoal hero with an oversized headline and a dark status panel

Source included

Coral Brutalist

A high-contrast direction for a federal data-platform firm: one saturated coral field, charcoal panels, mono labels, display type at full width.

Next.js 16 Tailwind v4 Framer Motion Not shipped

Light agri-tech hero with a 3D drone model hovering beside the headline

SoilScale

Multispectral crop intelligence. A live 3D drone holds the fold, because the product's claim is that the hardware sees what you can't.

Next.js Three.js Light theme

Plain white centred landing page with a black headline and one blue button

ShipFourteen

My own agency site. One offer, so no navigation problem to solve — only an objection problem. The plainest thing in this collection, on purpose.

Next.js Own brand Shipped

Evening photograph of a golf simulator at a garden party with a serif headline over it

Birdiez 2 Go

Tour-grade golf simulators delivered to private events. One photograph does the whole job of the fold; gold on navy carries the rest.

Marketing site Editorial serif Shipped

Deep forest-green hero with an amber sunrise emblem and a high-contrast serif headline

Awesome by Choice

Leadership training and keynotes. Forest green and lamplight amber instead of the category's headshot-on-white default.

Single page Self-contained HTML Shipped

Calm cream page with a single sage-green button reading I lost someone

Grief Guides

Answer five questions after losing someone, get only the tasks that apply to you. Two builds — Kansas and Slovakia. The hardest brief here.

Product concepts

Invented data

Light blue-to-cream marketplace hero with two buttons and a row of trust signals

SitterBolt

Two-sided babysitting marketplace. Both sides get an equal button, and every element below the headline is answering "is this safe?"

Marketplace Two-sided Concept

Near-black page with a live pronunciation recorder showing a word and its phonetic spelling

Learning Tools

Two education products, one tactic: put a working piece of the product in the fold, because nobody believes the claim until they've used it.

SpeakSharp Uni-Vise Dark UI

Freight dispatch dashboard with a map of central Europe and a stack of alert cards

Dispatch Board

Which truck isn't earning today, and why. Every alert resolves into three lines: what, why, and the next step to take.

Dashboard Fleet Sample data

Two-pane contract archive interface with a highlighted clause on the right

Smart Contract Archive

Ask in plain language, get the contract and the exact clause highlighted. The design problem is trust, not search.

About this repo

Each entry is either full source or a screenshot study. Client projects appear as screenshots and write-ups only — their content and branding belong to the client, so it is not republished here. Where full source is included, the client's copy, assets and identity have been replaced with an invented brand, and the entry says so.
