> Software engineer building AI-agent infrastructure and Web3 systems — TypeScript SDKs, agent identity and discovery, and Ethereum L2 rollup tooling.

Location: Pune, India. Email: 04syee@gmail.com.

Software engineer with 4+ years building backend, platform, and full-stack systems across Web3 and AI infrastructure. At [Zynd AI](https://zynd.ai/) I work on autonomous-agent infrastructure: the TypeScript Agent SDK, AgentDNS (federated identity and service discovery for agents), the agent registry and reputation layer, and agent-to-agent communication with x402 payments. I also designed and deployed a live on-chain agent registry and discovery protocol on an EVM agentic L1 testnet. Before that I built rollup deployment infrastructure for the Tokamak Rollup Hub at [Tokamak Network](https://www.tokamak.network/) — provisioning, deployment validation, monitoring, and cleanup of application-specific Ethereum Layer 2s. I've also shipped prediction-market backends and done security research across web, API, and smart-contract surfaces. [MLH Fellow (NEAR Protocol)](https://near.org/) and winner of 15+ Web3 hackathons across ecosystems including ETHGlobal, Mantle, and Optimism.

## Experience

- **Senior Research Engineer, [Zynd AI](https://zynd.ai/)** (Mar 2026 – Present, Remote): Engineer agent infrastructure and developer tooling, including the Zynd TypeScript Agent SDK for agent registration, discovery, invocation, and network interaction. Designed and implemented AgentDNS, a federated identity and service-discovery layer using Ed25519 identities and bidirectional handle verification. Build the agent registry and discovery layer, combining capability-indexed discovery with reputation mechanisms for selecting trustworthy agents. Contribute to A2A communication and x402 payment infrastructure so autonomous agents can coordinate and exchange value without human intervention. Work across API, SDK, identity, discovery, and execution layers, and prototype integrations between agent systems, decentralized identity, and EVM execution environments.
- **Blockchain Engineer, [Tokamak Network](https://www.tokamak.network/)** (Dec 2024 – Mar 2026, Remote): Worked on the infrastructure behind the Tokamak Rollup Hub (TRH), a platform for provisioning and operating application-specific Ethereum Layer 2 rollups. Built and integrated backend services and tooling across the rollup deployment lifecycle — provisioning, configuration, deployment validation, monitoring, and cleanup — on containerized, cloud-oriented infrastructure that automated away manual operational steps. Contributed to system design and architecture discussions around platform services, rollup lifecycle management, and developer workflows. Ran end-to-end testing and validation across rollup components, bridges, monitoring, and platform integrations, and improved reliability and developer experience through configuration validation, operational tooling, and documentation, collaborating asynchronously with an international engineering team through to production deployment.
- **Full-Stack Blockchain Developer, [Spredd Markets](https://spredd.markets/)** (Apr 2025 – Nov 2025, Remote): Built backend and application components for a prediction-market platform across application logic, APIs, blockchain integrations, and execution flows. Implemented cross-protocol integrations and aggregation logic across multiple prediction-market systems, worked on application architecture for high-throughput markets including appchain and Layer 2 scaling approaches, and contributed to backend workflows involving asynchronous execution, external protocol integrations, and on-chain settlement.
- **Protocol Engineer & Co-Founder, [ShillTube](https://github.com/0xSY3)** (Jan 2025 – Jun 2025, Remote): Co-founded and engineered an application combining backend services, smart contracts, tokenomics, and DeFi primitives. Designed and implemented smart contracts with an emphasis on gas efficiency, correctness, and protocol safety, and built the backend logic connecting application interactions with on-chain execution and economic flows.
- **Web3 Protocol Developer, [MLH Fellowship (NEAR Protocol)](https://near.org/)** (Jul 2023 – Sep 2023, Remote): Developed Rust smart contracts under mentorship from NEAR Protocol engineers. Worked with sharded blockchain architecture, distributed execution, and protocol-level system design. Contributed to a hackathon-winning project that progressed toward a funded startup.
- **Security Researcher, [Hacktify Cyber Security](https://github.com/0xSY3)** (Feb 2023 – Mar 2024, Remote): Performed web application, API, infrastructure, and smart-contract security assessments. Conducted vulnerability research and security testing across application and infrastructure layers.

## Hackathons

- **NEAR · Web3 BUILD Hackathon** (2023): Built Transpact — a contract verification layer on NEAR Protocol. On-chain attestations for off-chain agreements, with cryptographic proof of delivery backed by NEAR's sharded execution.
- **Stacks · Ready Layer 2** (2024): Built ClarityCraftAI — exploited Clarity's decidable, formally verifiable language properties to generate Bitcoin-finalized smart contracts that are provably safe by design. No reentrancy by construction; the AI enforced it.
- **Optimism · DoraHacks 2024** (2024): Built Optimus Prime — surfaced OP Stack-specific developer pain: cross-layer transaction tracing, L2 state root debugging, and sequencer interaction monitoring rolled into a unified AI assistant with live on-chain analytics.
- **Filecoin · Encode Scaling Web3** (2024): Built InterPlanetary Storage Exchange (IPSE) — a decentralized marketplace connecting storage providers and clients on Filecoin's IPC subnet. On-chain deal negotiation and settlement without any centralized intermediary.
- **Polkadot Prodigy · TAIKAI** (2024): Built PolkaDEV AI — tackled the steep learning curve of Ink! WASM contracts and substrate pallets. InkCraft scaffolds Ink! contracts from intent; AuditDOT reasons about WASM execution semantics that Solidity tooling fundamentally can't reach.
- **Polkadot Solidity Hackathon** (2026): Built Dust Protocol — stealth transfer and private swap primitives on Polkadot EVM. Sender and recipient have zero on-chain linkage; funds dissolve into the chain and re-emerge at a destination with no traceable path.
- **Solana Web3 AI · Encode Club** (2024): Built SolDev AI — Solana's account model and PDAs diverge sharply from EVM. Trained tooling to reason about account ownership constraints, CPI signer verification, and rent-exempt lamport requirements that trip up most developers coming from Solidity.
- **Fuel Hack · Encode Club** (2024): Built SwayCraft — Fuel's FuelVM executes transactions in parallel via a UTXO model, and Sway is its Rust-adjacent native language. Produced contract templates and a dev companion built for this execution model, not retrofitted from EVM patterns.
- **Mantle · HackQuest** (2024): Built MNT DEV AI — Mantle's modular stack separates execution, data availability via EigenDA, and settlement. Tooling that understands this layering and surfaces gas inefficiencies specific to Mantle's sequencer fee structure, not generic EVM advice.
- **Unfold 2024** (2024): Built and shipped a cross-chain application on-site at India's largest Web3 hackathon by CoinDCX — coordinating state across multiple chains under a live audience and 36-hour constraint.
- **Safe Agentathon** (2025): Built CLI-AGENT — Rust on Arbitrum Stylus compiles to WASM, not EVM bytecode. Wrote static analysis that understands Rust's ownership model and memory safety invariants in the context of Stylus execution — gaps no existing Solidity tooling can fill.
- **Starknet Re{ignite} · HackQuest** (2025): Built on StarkNet's Cairo execution environment — worked with felt-field arithmetic, STARK-native provability, and ZK-native state transitions for private on-chain applications that derive security from proof validity rather than economic incentives.
- **Surreal World Assets · Encode Club** (2025): Built a decentralized IP registry on Story Protocol — creators register works on-chain and issue programmable licenses that resolve commercially via smart contract. Royalty splits and sublicensing logic enforced at the protocol layer, no intermediary.
- **Hyperliquid Community Hackathon** (2025): Built on Hyperliquid's fully on-chain perpetuals orderbook using the Rust SDK — automated position and execution logic that runs directly against the on-chain matching engine with no off-chain relay or centralized keeper.
- **MultiversX AI MegaWave** (2025): Built MultiX — an autonomous DeFi agent on MultiversX that monitors cross-protocol opportunities and executes strategies without manual triggers. Agent logic runs on-chain; no frontend, no human in the loop.
