Product content automation platform for e-commerce

Web Programming

Goal: full cycle of filling and updating online stores — from parsing products in competitors to content uniqueness and automatic delivery of XML feeds to marketplaces.

Web control panel (Flask + SQLAlchemy + Flask-Login/Bcrypt/Migrate): authorization, roles, admin panel (CRUD users), background task execution with status pages, content pages, export, suppliers, GPT rewriting, photo uniqueness, XML tools.
5 marketplace parsers — Rozetka, Prom, Wildberries, Alibaba, Amazon — each with its own product card, pagination, and anti-bot logic.
… SSIM engine for image uniqueness — key technical feature. Two-step iterative processing to bypass duplicate filters of marketplaces: first "soft" modifications (internal frame, deterministic noise, color/brightness/contrast shift, rotation with cropping to the maximum inscribed rectangle, watermark), then "hard" (scaling). Parameters are deterministically enhanced from 100% to 200% over several attempts until structural similarity falls below the target SSIM. Support for AVIF/Pillow.
Two implementations of description rewriting via GPT — through OpenAI API and through the browser version of ChatGPT, working with Google Sheets columns, support for confirmation code.
Server service for auto-updating XML feeds: sources Prom / Rozetka / Excel jobs, "centers" → groups → stores with individual configs, background task queue, memory leak protection, run history, REST API, execution markers.
Bidirectional synchronization with Google Sheets / Drive: XML price → master table → correct XML for Prom and Rozetka, normalization, bilingual fields.
Supplier dropship feed module: product import, auto-mapping of categories, XML generation and merging, master table synchronization.
Stack: Python, Flask, SQLAlchemy, Flask-Login/Bcrypt/Migrate, Gunicorn, aiogram, Playwright, OpenAI GPT API, Google API, Pillow + AVIF, NumPy, scikit-image (SSIM), threading/queue.
Timeline: 2–3 months

Telegram bot for automatic reviews on freelance exchange

Bot Development

Goal: to not miss relevant freelance orders and to instantly place bids ahead of competitors — 24/7, without human involvement.

Userbot-monitor (Telethon) listens to the order channel in real-time; two independent scenarios are triggered for each new message — forwarding to the admin based on a list of keywords and automatic bid submission based on patterns.
Smart morphological matching: words are converted to their base form (lemmas), short roots (≤3 characters) match strictly by the whole word/lemma, longer ones — prefixally ("automaton" → "automation")
… Automatic bid submission through a controlled antidetect browser: authorization, opening the task, clicking "Place Bid", filling in the comment, deadline, and amount. The amount is calculated considering the minimum bid for the currency and the client's price (the maximum is taken).
2FA authorization via bot: when the site requests a code, the bot writes to the admin, waits for the code (polling the database, up to 5 attempts, timeout 10 minutes) and enters it on the site. A separate watcher synchronizes the waiting state for the code with the FSM of the bot.
Inline management menu: lists of keywords, monitoring groups, response templates, and trigger patterns (FSM scenarios for adding/removing).
Reliability: one browser at a time (asyncio.Lock), screenshots + text reports on any error in Telegram, WAL mode SQLite, running under Xvfb on a Linux server.
Implemented in two versions: full (auto-bids + 2FA) and simplified (keyword monitoring + auto-reposting of tasks).

Stack: Python, aiogram 3 (FSM), Telethon / Pyrogram, Patchright/Playwright, pymorphy3, SQLite (WAL), asyncio, Xvfb (Linux server)
