Small websites, handy scripts and AI visuals – built fast and explained clearly.

Demo project

Equipment rental website “Zelený klíč”

A static website for a fictional tool and cleaning-machine rental: home page, catalogue with 3 categories and 6 machines, machine detail with day/weekend rates and deposit, and a booking form with dates and add-ons that calculates the price. Works on desktop and mobile.

• Plain HTML, CSS and JavaScript, no paid plugins
• Booking form demo (in a real site it would send an e-mail or connect to a booking system)
• For a real client I would build it on WordPress so they can edit prices themselves

Demo project

Sylius e-shop detector (Python)

A script that takes a list of domains and tells whether each e-shop runs on the Sylius platform. It looks only at the public home page (respecting robots.txt, 3 s pause between sites) and writes a CSV with result, confidence 0–100 and the evidence it found.

Real test on 16 domains (19 Oct 2026):

Known Sylius shops (official demo + 6 live shops)	7 / 7 detected
Control shops on other platforms	4 / 4 correctly rejected
Sites behind a password or bot protection	5 marked “uncertain”
False positives	0

Download the full sample CSV

Python standard library only, no extra packages. It does not bypass bot protection and collects no personal data.

AI-generated samples

Photorealistic AI interiors

Six of 30 interior visuals (3328×1856 px) in different styles, generated with open-licence AI models (Qwen-Image, Apache 2.0) and checked one by one for visible artefacts, plus a short AI camera move (Wan 2.2). Useful for mood boards, listings, social posts or showing a client a style before a redesign.

These images are AI-generated, not photos of real rooms or my own design work.

Demo project

Short-form video: one reel, three hooks

Three versions of the same 9-second vertical reel (1080×1920) that differ only in the first 2.5 seconds – the hook. This is how you A/B test what makes people stop scrolling. Captions, slow pan and a branded footer, edited with a reusable ffmpeg pipeline, so new variants take minutes.

Footage: my own screenshots of the demo rental website above, so no third-party rights are involved.
