Senior IT Engineer · Backend architecture, blockchain & enterprise AI
LinkedIn · Upwork · Ethereum Magicians
I am a software engineer with 17+ years of experience building high-load backend services, custom blockchain systems, and AI applications for enterprise clients. I design and implement systems in Rust, Go, C++, Solidity, and Python, with experience across web applications, decentralized protocols, and infrastructure.
My work combines hands-on engineering with technical leadership. I focus on architecture, performance, and reliability, from low-level components and transaction flows to production AI systems.
Experience: DevLab Co. Ltd., MDEX, Biswap, CoinPayments, Iconosquare, Airbnb, Proarise LLC, Quantcast.
- AI systems: Autonomous agent workflows, multi-agent orchestration, retrieval pipelines, and secure LLM infrastructure. My work includes GraphRAG, Corrective RAG, and Agentic RAG, with evaluation, tracing, guardrails, and cost monitoring.
- Blockchain and backend: Custom L1/L2 protocols, EVM applications, smart contract audits, cross-chain bridges, exchange infrastructure, and trading, arbitrage, and MEV bots.
- Applications and infrastructure: Web interfaces and APIs, data storage, cloud deployments, and delivery pipelines, using TypeScript, JavaScript, React, AWS, and Kubernetes.

MCP Scanner — A security scanner for MCP servers, source code, and packages. It checks protocol behavior, authentication, prompt injection, tool poisoning, and dependency vulnerabilities, reporting findings alongside gaps in analysis coverage. Supports SARIF output and severity-based CI checks. Go · MCP · Security analysis · SARIF.
Agent Commerce Gateway — A self-hosted gateway that exposes existing APIs to AI agents through MCP and supports payments through x402. Payments go directly to the merchant wallet; the gateway does not hold funds or private keys. TypeScript · MCP · x402.
RWA Tokenization Platform — A self-hosted platform for issuing and managing permissioned tokens backed by real-world assets. It combines auditor-authorized minting and burning, transfer controls, and on-chain redemption with a Go backend and React administration interface. Solidity · Go · React.
