CV
Backend Engineer / Automation Architect
I specialize in developing fault-tolerant SaaS architectures, anti-fraud system evasion (Stealth technologies, browser fingerprint spoofing, human behavior emulation), and complex API integrations.
Core Tech Stack & Focus Areas:
Python, Playwright, asynchronous task queues (asyncio), PostgreSQL
High-Risk platform automation (TikTok, Telegram, Meta).
Development of modular management systems (MoE architectures) and dynamic proxy rotation.
Important Notice: I work strictly under NDA. Due to the sensitive nature of bypassing advanced platform security algorithms, I do not publish system architectures, server logs, or client UI/UX interfaces in my public portfolio. My clients' business security and anonymity are my absolute priorities.

Zero-Code Admin Console: Managing Telegram Bot/Website Database
Example of implementing a custom control panel (Admin console) for an autonomous IT ecosystem. This interface connects a Telegram bot, an external payment gateway, and the website's database into a single monolith, allowing management of the entire project without programming knowledge (Zero-Code).
Implemented functionality under the hood:
1. Total monitoring: logs, payment statistics, active user sessions in real time.
… 2. Financial core: setting up rates, discounts, trial periods, and supporting recurring payments (auto-renewals).
3. Access automation: the system automatically grants VIP status after a successful transaction and strictly automatically revokes it after the time expires.
4. User management: the ability to manually grant/cancel subscriptions, block users, and set individual conditions.
The architecture is designed with a focus on maximum fault tolerance, data security (High-Risk), and increasing customer LTV (retention).
