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.
