Test project8 Jul 2026

vulpecula - «Косвенно», a Bayesian inference console built for an AI-first design-studio test task

An AI-first test task for a design studio: an interactive mini-app where you edit indirect observations and a probabilistic report recomputes live. Shipped three scenarios on one scenario-blind engine - how many rabbits raid a farm (Poisson evidence), which of the foxes is the poacher (log-odds nomogram), how many bugs are left (capture-recapture) - with a zero-dependency Bayesian core where every number on screen is derived, never hardcoded. Editable records with live validation, a posterior chart, leave-one-out attribution bars ('remove this observation and 2,8 becomes 3,3'), permalinks, a change journal that spells out every edit, JSON export with preview, a scripted 40-second tour on its own page, and an in-app AI worklog documenting rejected AI suggestions with measured evidence. React 19 + TypeScript + Vite + Tailwind 4 + Zustand, ~1100 unit tests, deployed on Cloudflare Pages.

achernar - a Next.js movie-catalog test task hardened into a real streaming appRemake

Test project9 Jan 2024

achernar - a Next.js movie-catalog test task hardened into a real streaming app

A Next.js 14 (App Router) + TypeScript movie-catalog landing that worked only on a wide desktop. Kept the original Netflix-style look intact and fixed it from the inside: dead 404 nav links, a leaking scroll listener with a broken cleanup, a non-focusable scroll-to-top control and a duplicate film entry. Then made it genuinely usable - a real responsive pass with a mobile bottom-bar, fluid type scaling and per-breakpoint Swiper carousels, plus an accessibility floor - and built it out from one screen into a working multi-page app: catalog, live search, TV channels, favorites (localStorage), account, a movie detail page and a custom video player streaming real CC-licensed films. Static export, self-hosted on Hetzner behind Caddy.

atria - a Vue server-list test task rebuilt into a warm infrastructure-ledger control panel

A Vue 3 + TypeScript master/detail test task: a list of servers on one side, an editor on the other, with generate, clear, save and delete. Fixed the real bugs (a non-unique v-for key that corrupted the list on edit and delete, Delete and Cancel buttons silently submitting the form, a Clear that left a phantom unsaveable editor, a home view that re-seeded random data on every navigation), then redesigned it end to end into an 'infrastructure ledger' - warm cream and ink on an OKLCH palette, monospace machine fields, a ruled index-number gutter as the signature - with a full accessibility and 390-to-1440 responsive pass. Vue 3 + TypeScript + Vite + Tailwind, self-hosted on Hetzner behind Caddy.

hamal - a React-internals learning repo rebuilt into a 28-specimen interactive logbookRemake

Test project3 Jan 2024

hamal - a React-internals learning repo rebuilt into a 28-specimen interactive logbook

A learning repo that was a single unstyled page of about a dozen React demos, every one hardcoded to a single purple, with blocking alert() dialogs, duplicate-id todo bugs and a login button the header never noticed. Rebuilt and expanded into 'Bench Notes' - 28 live, categorised 'specimens' (core and concurrent hooks, the HOC and render-prop patterns, an external store, portals, error boundaries, the class lifecycle next to its useEffect twin) on a bespoke OKLCH lab-logbook design system, with the real bugs fixed and a full accessibility and responsive pass.

alkaid - a 2021 portfolio rebuilt in Nuxt with five live demos

A 2021 personal portfolio rebuilt into an editorial Nuxt site whose work section opens five bundled demo builds - a travel landing, a game-studio site, two agency portfolios and a travel marketplace - each lifted from loose static HTML into native, clickable Nuxt routes.

dubhe - a users-and-posts board rebuilt into a card-catalog work surface

A Vue 3 + TypeScript test task: a board that loads ten authors and their posts from JSONPlaceholder and lets you add, edit, delete and drag posts between authors. Fixed the real bugs (a broken validation-schema import that crashed every form, serial fetches with no per-author loading or error states, one hidden edit modal mounted per card), then redesigned it end to end into 'Atelier Ledger' - a warm-paper card-catalog system with folder-tab columns and index-card posts on an OKLCH palette, a full-height app shell that never scrolls the page, animated drag and modal transitions, and a real accessibility floor. Vue 3 + TypeScript + Vue CLI.

merak - an abandoned Union-Find skeleton rebuilt into an interactive algorithm visualizer

A Vue 3 test-task repo that was never finished: the original only drew a row of white dots on a canvas, carried a hardcoded edge list it never used and implemented none of the actual disjoint-set algorithm. Rebuilt from scratch into a real teaching tool - an animated SVG forest, union by size/rank and path-compression toggles, a scrubbable guided demo, a free-play mode, a live parent/size table, metrics and history, all on a bespoke OKLCH 'terrazzo' design system.

alcor - a random quote generator rebuilt around a dead API and given an editorial redesign

A static random-quote test task whose entire premise was broken: the third-party API it depended on (api.quotable.io) had shut down, so the live app hung on 'Loading...' forever. Rebuilt to read from a curated, locally-bundled set of real, well-attributed quotes with no-immediate-repeat rotation - no network, nothing to fail - then redesigned end to end into a quiet editorial 'ink on warm paper' system with OKLCH light/dark theming, working Share and Copy actions, full responsiveness and a real accessibility floor. Static HTML + CSS + vanilla JS.
