About Me

Full-stack developer with over 15 years of experience building web and mobile applications, crafting system architectures, working with DevOps, managing blockchain products, and leading teams. Skilled at developing scalable platforms from scratch, integrating external services, and delivering UX-driven interfaces.

Currently building a cloud router management platform using NestJS, React, PostgreSQL, and Docker. Previously developed crypto wallets, a blockchain explorer, and 3D/AR editors.

⚡ Currently diving into Solana ecosystem: learning Rust, Anchor, building dApp prototypes, and exploring DeFi mechanics.
Excited about HFT bots, order books, arbitrage, and Web3 infrastructure.
🧠 Following AGI, AI agents, and open-source LLM infrastructure—interested in autonomous systems and next-gen products.

Seeking a role at the intersection of blockchain, AI, and high-load distributed systems.

Work Experience (13 years 4 months)

Cloud Routers (Estonia, cloud-routers.com)

🗓 March 2024 – Present (1 year 4 months)
Full Stack Developer
Developing a platform to manage physical & virtual routers—underpinning proxy and VPN services.

Tech Stack

Frontend: React, Redux Toolkit, TypeScript
Backend: NestJS, PostgreSQL
API: REST with role-based access, external integration

Key Contributions

Built UI to manage routers, traffic distribution, user accounts, tunnels, and projects
Designed a scalable backend API handling high load, auth, rate limits, monitoring
Engineered IP address management: rotation, reconnect, reboot; tunnel support (OpenVPN, Shadowsocks, SOCKS5)
Implemented team collaboration tools: roles, invites, resource sharing
Integrated geolocation, traffic/temperature metrics, uptime, and firmware stats

This startup experience sharpened my skills at the crossroads of networks, hardware, and cloud—building products from the ground up under resource-constrained, uncertain conditions.
