Demo mockup for portfolio: contractor's page who designs and installs heating for private homes. The third theme and third design contract: here the drawing is a white grid canvas, steel blue, annotations, and a stamp, like on a project sheet. What's…

Demo mockup for portfolio: barista course page. The second mockup out of three, and the design here is intentionally different — newspaper layout, serif font, cream paper, and margin notes instead of cards. What's inside: 1. First screen with an…

Demo mockup for portfolio: a page for a portable power station store. I chose the theme myself — I needed an example of a product page where there is something to calculate and compare. On the cover — six real screenshots of the page from the browser…

Own project: demo jewelry store in Ukrainian, from the storefront to the owner panel. What's inside: 1. Storefront: main page, categories, product cards, options with separate prices and stock. 2. Filters by price and material, search, sorting…

Own project. A bot for a community that keeps a chronicle of a fictional world. Each report is not sent as text in the chat, but as an image: parchment background, typed text, without service signatures. What has been done: 1. Card rendering on…

Own project. Not a clone of Fandom and not a wiki builder: a platform where each material has a type, status, and level of canon, and changes go through a draft. What works: 1. Creation of a draft, editor, submission for review. Published content…

Own project. Flutter-based application that evaluates the calorie content of dishes and keeps a food diary. One codebase for iOS and Android. What has been gathered: 1. Navigation, themes, localization, and screen states. 2. Screens for scanning…

Course project for an IT specialty student: software part according to the specifications, database schema, and explanatory note. What is included in such work: 1. Code with comments and separation into layers: database work is isolated from the…

Translated the page of a portable SSD and a fragment of the instructions from English. These are two different registers in one order. The marketing block can be translated freely, the instructions cannot: each step must remain a step, and warnings…

Rewrote the "About Us" page for a furniture workshop. The client requested to remove fluff while maintaining the same volume. The original text contained nine evaluative statements without any evidence: market leader, high quality, years of…

Landing page for mobile washing machine repair, four screens. Main idea: to show real prices instead of "from 300 UAH." In this niche, people are already tired of the fact that the amount turns out to be three times higher on-site, so an open price…

A blog article for a generator store on how to choose the right power and not overpay. The task was twofold: to address recurring questions that managers hear daily and to gather traffic for the query "how to calculate generator power." What I did: 1…

Text for the category page "Infrared Heaters" for a heating store. Task: to cover search queries while simultaneously helping a person choose. A common mistake of such texts is that they list keywords and explain nothing. What I did: 1. Broke the…

Description for the battery screwdriver card. The task was to explain the characteristics through practice: not "powerful motor," but how many screws the tool can drive on one battery and what it can actually drill. What I did: 1. Compiled a…
