Experience

Blockchain Engineer
BlockDeep Labs
2025 - 2026
At BlockDeep Labs, I worked across both blockchain engineering and AI product development. I engineered protocol-level blockchain functionality in Rust, building custom Substrate pallets, runtime upgrades, developer tooling, and testing infrastructure for enterprise clients across the Polkadot ecosystem. Later, I also helped build an AI-powered Web3 portfolio agent capable of analyzing multi-chain wallets, generating portfolio-aware recommendations, and preparing executable transaction flows through a chat-based interface using wallet data, live pricing, and routing integrations.
Blockchain Engineer
InvArch / AbstractedCo
2024 - 2025
Led development of the InvArch DAO Management Portal, building XCM-based asset and DAO management tools for the Polkadot ecosystem using TypeScript, React, and RPC integrations. I also engineered protocol-level runtime functionality in Rust for InvArch Network and Tinkernet using the Polkadot SDK (Substrate). In addition, I worked on MPC-based omnichain account infrastructure, including AI agent-assisted transaction flows where agents and users could jointly participate in transaction initiation, approval, and execution. I also built an MVP SDK for a unified MPC-controlled omnichain account system, designed for direct use by both developers and AI agents, and conducted research on MPL-404 hybrid assets on Solana.
