I'm a protocol engineer and founder with 7+ years building on-chain systems. I led a team of 6 engineers at Vaultline, scaling a cross-chain DeFi protocol from $3M to $420M TVL across 9 EVM chains with zero loss of user funds. I'm currently building Orbitra — governance infrastructure with zk-aggregated voting, built in Solidity, Rust, and Circom.

}Hello! I'm Shubham — a protocol engineer and founder with 7+ years of experience building on-chain systems. I led a team of 6 engineers at Vaultline, scaling a cross-chain yield aggregator from $3M to $420M TVL across 9 EVM chains. My stack is Solidity, Rust, Foundry, and TypeScript, with recent deep work in zero-knowledge circuits, governance design, and gas optimisation. I'm open to Protocol Lead, Head of Engineering, and Staff Engineer roles at web3 infrastructure companies.
I started my career building enterprise blockchain pilots at Blockwise, led web3 development teams at Sigil Labs through the 2021 cycle, and tokenised a 300-vehicle logistics fleet at Freightmint before leading protocol engineering at Vaultline — where I designed the vault architecture and took the protocol through multiple audits with zero loss of user funds. In February 2025 I co-founded Orbitra as CTO, building governance infrastructure that now secures $184M in treasury assets across 40+ DAOs.

Orbitra
Modular governance stack for DAOs: optimistic proposal execution, delegated and quadratic voting, and a timelocked multisig fallback. Votes are aggregated off-chain with zk-proofs and settled on Ethereum, cutting per-vote gas by ~92% while keeping results verifiable. Currently secures $184M in treasury assets across 40+ DAOs.
Vaultline
Designed and built 70%+ of the vault architecture: ERC-4626 strategy vaults that auto-compound across lending markets and AMMs on 9 EVM chains, with keeper-driven rebalancing and a circuit breaker that pauses strategies on oracle deviation. Scaled TVL from $3M at launch to a peak of $420M with zero loss of user funds.
Freightmint
Tokenised a 300-vehicle logistics fleet as dynamic ERC-1155 assets whose metadata updates from on-road telemetry via Chainlink oracles. Investors hold fractional exposure to fleet revenue, with monthly yield distributed on Polygon. Brought a traditionally illiquid asset class on-chain with full KYC gating.
Sigil
Research project combining NLP sentiment from crypto social channels with on-chain flow data to generate short-horizon trading signals. Backtested across 24 markets; published the methodology as my final-year paper.
The path so far.
Building governance infrastructure for DAOs: zk-aggregated voting settled on Ethereum, securing $184M in treasury assets across 40+ organisations.
- ▸Architected the core governance contracts and a Circom-based vote aggregation circuit, reducing per-vote gas cost by ~92% while keeping tallies verifiable on-chain.
- ▸Took the protocol through three independent audits with zero critical findings; set up a $250K bug bounty programme.
- ▸Own the full stack end to end: contracts, Rust prover service, subgraph indexing, and the Next.js/wagmi governance dashboard.
- ▸Onboarded 40+ DAOs and grew active delegates to 48K+.
Led a team of 6 engineers scaling a cross-chain yield aggregator from $3M to a peak of $420M TVL across 9 EVM chains with zero loss of user funds.
- ▸Managed a team of 6 engineers: hired, onboarded, and mentored across sprint planning, design reviews, and audit preparation.
- ▸Designed the ERC-4626 vault and strategy architecture; shipped 64 strategies across lending markets and AMMs on 9 chains.
- ▸Built keeper-driven rebalancing and harvest automation, cutting harvest gas costs by 38% through batching and calldata optimisation.
- ▸Implemented an oracle-deviation circuit breaker that auto-paused affected strategies during two market-wide depeg events, protecting user funds.
- ▸Maintained 99.95% keeper uptime with on-call rotation, Tenderly alerting, and pre-signed emergency transactions.
Built the tokenisation layer for a 300-vehicle logistics fleet: dynamic ERC-1155 assets backed by live telemetry and monthly on-chain revenue distribution.
- ▸Designed dynamic ERC-1155 contracts with metadata driven by Chainlink oracles feeding vehicle telemetry on-chain.
- ▸Built the revenue distribution system paying monthly yield to 2,100+ holders on Polygon, with KYC-gated transfers.
- ▸Wrote the indexer and investor dashboard in Node.js and React.
Led two cross-functional teams shipping NFT launches, token contracts, and dApp frontends for clients during the 2021 cycle.
- ▸Delivered 9 token and NFT launches for clients, including ERC-721A mint contracts with Merkle allowlists.
- ▸Built dApp frontends in React/Next.js with ethers.js and WalletConnect integrations.
- ▸Directed two teams in Agile Scrum; established testing and deployment processes that reduced post-launch incidents by 30%.
Started in web3 building enterprise blockchain pilots on Hyperledger Fabric and early Ethereum smart contracts for supply-chain clients.
- ▸Built Hyperledger Fabric chaincode and Ethereum contracts for supply-chain provenance pilots.
- ▸Developed Node.js middleware connecting legacy ERP systems to on-chain records.
- ▸Wrote test suites in Truffle and Mocha; introduced CI for contract deployments.
Graduated. Final-year research on ML-driven market signals — also wrote the paper for the same.
