I build AI systems and backends
that actually ship.

Solution

Built a Django system with an OpenAI-powered chatbot: personalized recommendations based on catalog and conversation history, automatic product description generation, intelligent session handling. The bot replaced first-line support and became a sales tool — no manager required.

Solution

Created a Telegram bot unifying multiple AI models in one interface. Implemented a credit and billing system, admin panel for managing models and users, and a scalable architecture with task queues. The project reached monetization within the first month.

Solution

Built a SaaS platform with shift management, employee roles, automated payroll calculations, and detailed reports. Manager dashboards and employee portals. The system cut operational costs and eliminated calculation errors.

Solution

Created a Django platform with automatic synchronization and import from external sources, advanced filters, and an SEO-optimized URL and page structure. Automated publishing cut time costs and increased lead flow through organic search.

Solution

Developed custom loyalty systems with point accrual, event-based automatic triggers, CRM integration via API, product feeds for Google Shopping and Telegram channels. Custom meta fields for flexible per-business configuration. Result: higher repeat sales and reduced customer churn.

Solution

Built a custom Django e-commerce platform: product catalog with categories and image galleries, user accounts with authentication, shopping cart and wishlist, a loyalty points system, weekly drop scheduling, and live purchase notifications for social proof. Responsive design with animations and a custom cursor system.

Solution

Built a platform that secures products with blockchain-backed dual QR codes — a public one for product details and a hidden one for authenticity verification upon purchase. Customers scan with a smartphone to instantly verify products and mint exclusive NFTs as proof of ownership. Includes an analytics dashboard for brands and a reward system to drive customer loyalty.

Solution

Built a platform where investors purchase fractional wine ownership as NFTs — starting from a single bottle. Each token is backed by a real bottle stored in Bordeaux City Bond with full insurance. Features include real-time pricing analytics, sommelier evaluations, a secondary market for token trading, and the option to claim physical delivery. Integrated with Stripe for payments and blockchain for provenance tracking.

Solution

Built a multi-tenant SaaS time-tracking platform with complete data isolation per cafe using PostgreSQL schema-per-tenant architecture. Each location gets its own workspace with employee management, real-time check-in/check-out, automatic work-hours calculation with overtime detection, and paid/unpaid holiday tracking. Role-based access separates admin dashboards (full control, employee CRUD, log editing, Excel export) from worker portals (personal schedule, clock in/out). Advanced filtering by date ranges (today, week, month, custom) and one-click Excel report generation for payroll processing. The system eliminated manual errors and gave owners instant visibility across all 5 locations.

Solution

Built a Telegram bot (@analysisinstagrambot) that performs deep analysis of public Instagram profiles in 5-30 seconds. The bot scores audience authenticity using 12 weighted factors, detects fake followers, calculates collaboration fit for the user's specific business niche and city, generates SWOT analysis and actionable recommendations. Architecture: FastAPI + Celery + PostgreSQL + Redis with a 4-stage fallback data pipeline (Apify, Instaloader, RapidAPI, Selenium). Features 24+ engagement metrics, multilingual comment analysis, circuit breaker pattern, Telegram Stars and Stripe payments, a Telegram Mini App dashboard, and PDF report export. Reports in Russian and Spanish. 132+ automated tests, 10,000+ lines of code.

Solution

Built a full-featured responsive website with detailed pages for every treatment category (facial, body, dermatology). Integrated WhatsApp appointment booking for frictionless patient scheduling. Created an online shop for skincare products and post-treatment care. Built a course platform for the clinic's educational programs. Implemented multi-channel analytics — Google Tag Manager, Google Analytics, Facebook Pixel, and TikTok — for marketing campaign optimization. SEO-optimized structure with Spanish-language content targeting local search queries.

Solution

Building a boutique matchmaking platform with a luxury dark-themed UI — film grain overlay, custom cursor, aurora glow effects, and smooth scroll animations. Multi-step application forms for men and women, full ES/EN bilingual support with client-side language switching, blog and success stories for social proof, user authentication with profile dashboard, and GDPR-compliant data handling.

Solution

Built a Telegram bot with a Mini App (Web App) that renders the full shop UI — catalog, product details, cart, and checkout — synced with the main Django backend via REST API. Drop notifications go out the moment new items launch, order status updates land directly in chat, and loyalty points are shared between the website and Telegram so customers earn no matter where they shop.

Solution

Built a Django 5 site (ES/CA/EN) with Tailwind + Alpine mobile-first UI, a 4-step booking wizard, per-doctor visual schedule editor with presets and a 30-day calendar, and an OpenAI-powered chat assistant (Rita). Rita auto-detects the user’s language, searches services, filters slots by date and time of day, and creates the booking through function-calling tools — with full conversation saved as a lead in the admin. Production runs on Heroku with Postgres; rate limits and a conversation window keep token cost under €2/month at expected traffic.
