Looking for a stable solution without workarounds or missed deadlines? I specialize in developing server systems, client-side software, and automation solutions of any complexity. I take on projects ranging from building systems from scratch to refactoring and scaling existing systems.

🛠 Development Areas:

1. Web & Backend Ecosystems
• High-traffic administrative interfaces and real-time dashboards (WebSockets)
• Development of portals, niche forums, and monitoring aggregators
• Mirroring, scraping, and adaptation of third-party web resources
• Deployment of reverse proxies, traffic processing and redirection

2. FinTech, Crypto & Web3
• Integration of nodes, blockchain networks, smart contracts, and merchants
• Exchange platforms, OTC marketplaces, and transaction mixers
• Non-custodial wallets and payment gateways

3. Automation, Scraping & Bots
• Multithreaded checkers, high-speed parsers, and automated registrars
• Complex scripts for server operating systems (CLI utilities, daemons)
• Telegram bot architecture: funnels, automated trading, support systems
• Custom extensions for Chromium-based browsers to modify pages and automate actions

4. Mobile Platforms & Apps
• Development of native and cross-platform software (Android / iOS)
• Creation of supporting API backends for mobile clients

Tech Stack:
Languages: Go • Python • C++ • C# • Node.js • PHP
Databases & Ops: PostgreSQL • Redis • ClickHouse • Docker • Linux Environments

🛡 Work Principles:

• Clean code: architecture free of “spaghetti code,” detailed logging, API documentation.
• Confidentiality: I do not disclose details of your projects or the logic behind your services.
• No missed deadlines: Time estimates include a buffer; regular updates throughout the sprint.
• Support: Free bug fixes under warranty after delivery.
• Guarantor: I strongly encourage working through reputable forum guarantors.
