InstaAnalyzer — Instagram influencer audit bot for SMEs

Built a Telegram bot (@analysisinstagrambot) that performs deep analysis of public Instagram profiles for businesses evaluating influencer collaborations. The bot scores audience authenticity (12 weighted factors), detects fake followers, calculates collaboration fit, generates SWOT analysis, and produces PDF reports in Russian and Spanish. Architecture: FastAPI + Celery + PostgreSQL + Redis with a 4-stage fallback data pipeline (Apify, Instaloader, RapidAPI, Selenium). Features include 24+ engagement metrics, multilingual comment analysis, circuit breaker pattern, Telegram Stars and Stripe payments, and a Telegram Mini App dashboard. 132+ automated tests, 10,000+ lines of code. Built for beauty salons, cafes, clinics, and SMEs in Spain and Europe.

Small businesses in Spain — beauty salons, cafes, clinics — spend EUR 500-5,000 per influencer campaign but have no way to verify if an influencer's audience is real. Fake followers and engagement pods waste marketing budgets, yet professional audit tools cost EUR 200+/month and require marketing expertise to interpret.
