CTO & Senior Distributed Systems Engineer
Architecting Resilient, High-Throughput Infrastructure & Applied AI Systems
🚀 Engineering Profile
I am a hands-on CTO and Senior Systems Architect focused on designing distributed infrastructure, bypassing complex hardware/software bottlenecks, and deploying Applied AI in production environments. I specialize in the convergence of extreme concurrency (Python/Rust), bare-metal orchestration, and modern frontend platforms.
Rather than just assembling frameworks, I focus on first-principles engineering: rewriting core library internals when they bottleneck, orchestrating bare-metal clusters to avoid cloud vendor lock-in, and integrating local multi-billion parameter LLMs directly into data pipelines.

🏆 Impact & Engineering Scale
⚡ High-Throughput Automation & Custom Protocols
- O(1) Memory Session Engineering: Bypassed native SQLite locking bottlenecks in Telethon by completely rewriting the internal binary session handling. Designed a custom
asyncpg-backed memory session with global asynchronous debouncing, enabling thousands of concurrent TCP connections per process without database saturation or memory leaks. - Local LLM Data Pipelines: Architected end-to-end data scraping and parsing networks. Deployed local multi-billion parameter AI models (Ollama/LM Studio) with cloud fallbacks to sanitize, rewrite, and format raw high-volume data streams into structured content for massive Telegram networks.
- Dynamic Container Auto-Scaling: Built a custom worker management plane using FastAPI,
aiodocker, and RabbitMQ to dynamically scale, monitor, and prune hundreds of isolated containerized workers entirely based on real-time message queue loads.
🛠️ Bare-Metal Infrastructure & DevOps
- Self-Hosted Data Centers: Eliminated cloud vendor lock-in (AWS/GCP) by designing and provisioning a complete private server infrastructure from scratch on bare-metal hardware.
- Hypervisor Orchestration: Built a resilient, hypervisor-driven environment utilizing Proxmox VE. Meticulously allocated and isolated LXC containers and VMs to separate CI/CD pipelines, internal databases, and Nginx routing topologies.
- High-Availability Proxy Layer: Architected dynamic SOCKS5/HTTP routing and rotation layers using Python and Rust to ensure high-availability tunneling and bypass geographic/rate-limit filters.
💼 Commercial Platform Engineering
- End-to-End E-Commerce Architecture: Architected SMM-GATE from the ground up, directing the full stack from the Next.js SSR frontend down to the lowest-level database schemas.
- Transactional Integrity: Engineered bulletproof financial transaction flows exploiting PostgreSQL atomic queries and
FOR UPDATErow-level locks, entirely preventing race conditions under concurrent load. - AI-Driven Defense: Integrated seamless, real-time automated AI content moderation pipelines using OpenAI Structured Outputs to preemptively block illicit or politically sensitive operations before they hit the database.
- Native Crypto Integrations: Implemented native blockchain payment gateway interactions (Crypto Pay, Custom APIs) complete with idempotent webhook processors to ensure exact billing accuracy.
