## Work experience

### Senior Software Engineer @ Fetch.AI
Jan 2026 – Present · Remote
Company: https://www.fetch.ai
- Took AEVS, a tamper-evident auditability layer for agent workflows, from concept to launched MVP it processed 1,000+ execution receipts in production.
- Shipped Web3 execution into the ASI1 platform on Ethereum mainnet: swaps, trades, price fetches, and on-chain reads directly from chat without exposing private keys, using EOA wallet integration and full token coverage via CoinGecko resolution.
- Built custom MCP servers for Uniswap V2/V3, token resolvers, and non-custodial transaction signing mechanisms.
- Interview engineering candidates for Fetch.ai hiring loops.

### Software Engineer – DeX @ Fetch.AI
Aug 2023 – Dec 2025 · Remote
Company: https://www.fetch.ai
- Built and deployed a production cross-chain bridge on mainnet (BSC → Ethereum) and ran the live migration of $1.8M in MTLX held by 103 token holders: zero incidents, zero funds lost, most of it completed within the first week. Developed the 3 smart contracts, complete backend infrastructure, and serverless execution layer end-to-end.
- Developed 15+ smart contracts across EVM (Solidity) and Cosmos (Rust) for an agent-based P2P OrderBook DEX protocol, security-reviewed by Fetch.ai's internal team. Designed an escrow-based settlement layer, built off-chain agent matching system, and coordinated on-chain execution.
- Built Node.js and Python backend systems with WebSocket integration for real-time orderbook updates coordinating agent logic and syncing on-chain/off-chain state.
- Created custom blockchain indexers for EVM and Cosmos chains to track events and maintain cross-chain state consistency for agent decision-making and live trading graphs.
- Stress-tested the platform with 5,000 concurrent simulated agents to validate Kubernetes autoscaling: pods capped at 100 agents each, with new pods provisioned automatically at 95% capacity, shaping the production scaling architecture.

### Software Engineer @ QSTN
Mar 2023 – Aug 2023 · Remote
Company: https://qstn.us/
- Built and deployed Rust-based NFT smart contracts on NEAR Protocol compatible with major marketplaces (Paras, Mintbase, Few-and-Far), supporting royalties and custom constraints.
- Launched a 1,000-NFT mainnet collection purchasable through both on-chain payments and Stripe fiat checkout.
- Implemented four wallet login flows ensuring seamless user onboarding and secure transactions.
- Built a backend using TypeScript, Node.js, and MongoDB, set up CI/CD, and wrote tests with Jest.

### Junior Software Engineer @ Blockbelly (Invex)
Apr 2022 – Feb 2023 · Remote
