Web3 & Backend Engineer

I build at the systems layer: decentralized protocols, DeFi infrastructure, and the backends that keep them honest. Language-agnostic by habit; I reach for whatever the problem actually calls for.

Featured Work

Projects I've shipped

Production tooling and protocols across DeFi, infrastructure, and developer experience.

Policy & observability layer for autonomous AI-agent payments

Sits between an agent and its wallet, enforces spending policy, and produces a tamper-evident, on-chain-anchored audit trail for every payment. Three-layer decision engine (deterministic policy + anomaly detection + LLM intent reconciliation → allow/escalate/block), Merkle-batched audit log, OpenTelemetry instrumentation.

Intent-based liquidity SDK

One swap(intent) call that abstracts 1inch Fusion+, Uniswap v4 hooks, and Paraswap. Routing engine with MEV-risk simulation, cross-chain execution, and gas optimization. 220+ tests.

TypeScriptRustSolidityUniswap v4MEV

Production-grade API release CLI

Automates the full release pipeline: version bump → Docker → Kubernetes → health checks, with automatic rollback, dry-run, and audit logging. Integrates AWS ECR, Docker Hub, GitHub Releases & Slack.

Autonomous Uniswap v4 LP manager

Monitors a liquidity position, detects out-of-range drift, and rebalances with no manual intervention. Written in async Rust with on-chain price monitoring and safe, gas-aware transaction handling.

Cross-chain anti-liquidation system

Autonomous AI agents monitor positions across Ethereum & Solana, prevent liquidations, and rebalance securely. Integrated a MeTTa-powered agent layer for decision-making across 95+ lending protocols.

Contributions upstream

Security-minded fixes and features across Ethereum tooling, DeFi cores, blockchain frameworks, and protocol infrastructure: hardening the systems other builders depend on.

  • Foundryfoundry-rs/foundryEthereum tooling · Rust2026

    Enabled forge verify-bytecode to run without a block explorer, so deployed bytecode can be verified against source in trust-minimized setups.

    Bytecode verificationSupply-chain trust
  • ConvexConvex-Dev/convexDecentralised platform · Java2026

    Hardened the Postgres wire-protocol decoder against malformed pre-auth frames, closing crash paths triggered by untrusted network input.

    Input validationProtocol hardening
  • Oasisoasisprotocol/oasis-sdkConfidential runtime · Rust2026

    Fixed the ROFL scheduler's domain_verification_token finalizing into an empty digest — identical tokens across domains — closing a cross-tenant custom-domain takeover and TLS MITM vector.

    Domain verificationMITM prevention
  • Aptosaptos-labs/aptos-coreMove VM · Rust2026

    Validated Move Identifier during deserialization for safer module loading — malformed identifiers are rejected before they reach the VM.

    Deserialization safetyVM security
  • Circlecirclefin/arc-node · evm-cctp-contractsNode robustness & CCTP2026

    Hardened node robustness against streaming-overflow DoS, spammer panics, and metrics drift; added ITokenMessenger interfaces and minFee fuzz invariants to the Cross-Chain Transfer Protocol contracts.

Workshop Speaker

Spoke at VIT Chennai's inaugural Blockchain Workshop for GDG on Campus, with 400+ registrations from students across multiple colleges. Designed it to go beyond theory: every participant left with something they had actually built on-chain.

  • 400+ registrations from students across multiple colleges.
  • Live MetaMask setup and a real Sepolia testnet transaction, verified on Etherscan.
  • Deployed a smart contract live in Remix and called it on-chain during the session.
  • Hands-on format: zero to working on-chain deploy in a single workshop.

1st Place + 2 Inco Track Bounties at DEFY'26

Built Azoth DAO, a privacy-first, agentic DAO powered by Inco & Nillion. Most DAOs default to radical transparency, which invites whale signaling, vote tracing, coercion, and bribery; Azoth removes those incentives entirely. Team: Naveen V, Vishal Prabhu, Kunal Singh Dadhwal, Frank Xavio.

  • Confidential governance on Inco: encrypted token balances & transfers, hidden proposal amounts, near-zero-signature UX via session-key delegation, and decryption + sensitive execution inside a TEE.
  • Agentic intelligence on Nillion: proposal analysis with nilAI, blindfold-encrypted sharded metadata via nilDB, and agents built with ERC-8004 + x402 pay-per-inference access.
  • Bonus build: a fully confidential UNO on Inco's Lightning SDK, with encrypted hands, cryptographically shuffled deck, and verifiable final state.

DataChain at ETHGlobal New Delhi

Built DataChain, an AI dataset marketplace that makes data sharing verifiable and privacy-preserving on Ethereum. Combined Filecoin and World ID under extreme time pressure and actually shipped it.

  • World ID: proved human ownership of datasets without exposing identity.
  • zkTLS proofs: cryptographically hid transaction details from third parties.
  • Verifiable NFTs: gave real on-chain ownership to datasets, no 'trust me, bro' deals.
  • Filecoin integration for decentralized, censorship-resistant dataset storage.

About

Builder at the systems layer

Engineer working close to the systems layer: decentralized protocols, DeFi infrastructure, and the backend services that hold them up. I care more about how a system behaves under load and adversaries than which language it happens to be written in, and I pick up new stacks as the work demands. Active open-source contributor across the ecosystem, from low-level language tooling to core DeFi protocols, and currently researching how to remove liquidations from decentralized lending entirely.

From the blog

Notes on Rust, DeFi, and building at the systems layer.

Apiforge takes merged code to healthy pods in production in one command, and rolls itself back in reverse if any step fails. A field guide to every way a release pipeline can quietly betray you.

One SDK across Uniswap V4, 1inch Fusion+ and Paraswap with built-in MEV protection, and the quietly-wrong bugs I had to kill to make sandwich-risk scoring actually correct.
