180 USD Turnkey website
HTML & CSS
What has been done: created a turnkey website — from design to payment setup and customer acquisition.
Design
Developed and assembled the website from scratch: it looks beautiful and is convenient on both smartphones and computers.
… Structured the page to guide the user from interest to purchase.
Payment
Integrated online payment processing directly on the website.
Full automation: after payment, access to the product is opened automatically — without manual work.
Customer acquisition (sales funnel)
Built the customer journey: first a free useful material → then warming up interest → final purchase. Because of this, people buy much more willingly than with direct "in-your-face" sales.
Set up advertising on Facebook/Instagram that attracts the targeted, interested audience.
Connected analytics: it is clear where users come from and at what stage they make a purchase.
Result: a ready-to-use website that independently sells the product and accepts payments.

34 USD Comprehensive technical SEO audit of the website
Website SEO Audit
Conducted a complete technical SEO audit of an online clothing store (Moldova). Analyzed 50+ parameters, identified critical issues blocking indexing and organic traffic growth.
What was done:
- Indexing analysis: sitemap, robots.txt, URL structure
… - Checked meta tags (title, description) on all pages
- Audited Open Graph tags for social media
- Analyzed Schema.org markup
- Checked loading speed (Core Web Vitals)
- Analyzed internal linking
- Checked alt attributes of images
- Compared with a competitor
- Analyzed positions in Google and keywords
Result: A 10-page PDF report with prioritized recommendations, ready code examples for fixes, and a traffic growth forecast after implementation.
Identified: 4 critical, 3 important, and 2 medium issues. Expected traffic growth after fixes — 50-100%

338 USD Crypto-design на Next.js 16 / React 19 — 97 Google PageSpeed
Javascript and Typescript
A full-fledged web application (Page Speed 97): animated landing page, dashboard with onboarding. A custom component library, Framer Motion, and strong TypeScript typing—tailored to the project's needs.
Live demo:
https://celestian-demo.vercel.app
…
18 pages in one application: animated landing page with video backgrounds and live charts, bot marketplace, dashboard with onboarding, auth, legal, and blog. Mobile-first responsiveness, dark and light themes, and multilingual support out of the box.
+ SEO-ready: each page has its own title and description, Open Graph and Twitter Card are configured, sitemap.xml and robots.txt are automatically generated, structured data (Organization + WebSite), and multilingual hreflangs are supported via next-intl. Simply remove the noindex option, and the site will immediately appear in search results.
+ Google PageSpeed: 97 points on desktop. This is the result of targeted optimization for Core Web Vitals: lazy-mounting heavy content via IntersectionObserver, preloading local fonts, tree-shaking heavy libraries, a modern browserslist without legacy polyfills, serving images in AVIF/WebP via next/image.
Stack:
— Next.js 16 (App Router, RSC, static generation)
— React 19 + TypeScript 5.9 (strict mode)
— Tailwind CSS 3.4 with custom theming
— Framer Motion — reveal animations, tilt 3D cards, marquee
— ApexCharts + Recharts — portfolio and performance charts
— next-intl — multilingual support
— Vercel CI/CD, deploy on every push

Terra Raccoons — Telegram Idle Clicker
Gaming Apps
Browser idle game in Telegram. The player builds a space colony of raccoons: terraforms planets, extracts resources, collects ships, sends expeditions, catches rare events. Created solo from scratch — from idea to sale.
Play → @TerraRaccoonsBot
… Game mechanics (30+)
1. Terraforming planets — turning dead worlds into habitable ones
2. 10 unique planets (3D canvas, 4 states for each)
3. Drones G1–G5 — gather resources while you are offline
4. Leveling up drones
5. 11 skills with random name generation through gacha, skills can be combined
6. Clicker for drones for active gameplay
7. Stations — upgrade storage and production
8. Moving drones between stations
9. Ships of 5 rarities (G1–G5) with unique graphics
10. Gacha boxes for ships
11. Merge system — combining duplicates into rarer ones
12. Hangar for ships and drones with sorting and filters
13. Expeditions — 8 types with different durations and rewards, directly related to ship mechanics
15. Speeding up and early completion of expeditions
16. VIP system
17. Leaderboard
18. Marketplace — online transactions between players
19. Global events with notifications in the bot (raccoon contract, anomaly, ancient signal, time distortion)
20. 20+ missions, daily and long-term
21. Progress through planets — unlocked as you grow
22. Bundle shop with resource packs
23. Premium currency Terrafract
24. Resource conversion
25. Ads to speed up progress
26. Payments through Telegram Stars and TON Wallet (in progress)
27. 14 languages (ru, en, zh, tr, it, pl, pt, es, de, fr, ja, uk, ar, hi)
28. One-tap authorization through Telegram
29. Offline progress — rewards accumulate while you are away
30. Onboarding for new players
31. Animations and effects when collecting rewards
32. Adaptive mobile interface
33. Notifications about the readiness of drones and ships
What the player feels: you log in for a couple of minutes five times a day and each time you get something new — resources have accumulated, an expedition has returned, a rare ship has dropped. No aggressive paywalls: you can play for free, donations speed up progress but are not mandatory.
## Technical Part
Stack: React 18, Vite, Zustand, Tailwind CSS / Node.js, Express, TypeScript, SQLite / JWT over Telegram initData / Winston / VDS on Linux, nginx, PM2 cluster.
Architecture:
- SSOT on the front end. One Zustand store holds all state, components subscribe to slices. No duplication between useState and the server.
- Hot-domain on the back end. In-memory cache over SQLite for hot operations (resource gathering, drone movement, station ticks) with delayed writing via FlushScheduler — the database does not choke under load.
- Thin controllers, thick domain. Routes only parse requests and call domain functions, business logic is tested without HTTP.
- Dynamic chunks i18n. Each language in a separate file, loaded on demand — the initial bundle is not bloated with 14 locales.
- ErrorBoundary with readable output. Render errors are caught and displayed on the screen with a stack trace, instead of a blue screen. Critical for Telegram WebView without DevTools.
- Anti-abuse multilayered. Expeditions are protected by a gate based on progress, terraforming requirements, rechecking events upon collection, nerfing exploit types.
Economy simulator. A separate tool that runs hundreds of virtual players and calculates ROI of sources, retention, convergence, profitability gap for F2P and paying players. Used for three major rebalances (V1→V2→V3→soft-deficit) to achieve equal ROI for all 11 sources and stocks at round numbers.
Deployment. One command: git pull && pm2 restart terra-backend && cd terra-gaming && npm run build. Frontend and backend on one VDS, nginx serves static files, proxies /api to Express. No Docker and CI/CD — can be fixed manually in a minute.
What I did: prototype in Figma, 3D assets, architecture, database, API, frontend, UI/UX, economy, balancing, deployment, admin panel. The game is in closed beta.
