Hi, I’m Meharab

Blockchain Engineer focused on smart contracts, DeFi systems, protocol design, blockchain infrastructure, and decentralized systems research.

I have almost 5 years of professional software engineering experience and nearly 4.5+ years of focused blockchain engineering experience across EVM ecosystems, Hyperledger Fabric, Substrate, Rust, Solidity, and blockchain backend infrastructure.

About Me

Building smart contracts, DeFi protocols, and blockchain infrastructure
Strong focus on Solidity, Rust, Go, and blockchain backend systems
Interested in protocol design, tokenomics, validator economics, MEV, cross-chain systems, and decentralized coordination
Experienced with both public blockchain ecosystems and private enterprise blockchain systems
Deeply interested in the intersection of blockchain, economics, infrastructure, and AI
Currently exploring advanced protocol engineering, Uniswap V4 Hooks, on-chain automation, Chainlink, and decentralized AI systems

Philosophy

I approach blockchain engineering from a systems-design perspective.

I am interested not only in writing code, but also in understanding:

Economic incentives
Security assumptions
Failure modes
Trade-offs
Scalability constraints
Governance design
Long-term protocol sustainability

I enjoy solving difficult engineering problems that require first-principles reasoning, research, and deep technical exploration.
