Full-stack engineer building DeFi protocols, AI agents, and Rust systems.
I work across three stacks: smart contracts in Solidity, AI agents and LLM tooling in Python with Claude and MCP, and performance-critical backends in Rust and Go. The systems I ship handle real liquidity, real users, and real money, so I write software that survives adversarial conditions.
On the DeFi side, my flagship is MantissaFi, a fully on-chain European options protocol that implements Black-Scholes-Merton pricing entirely in Solidity. At @mahaxyz I work on the core protocol: stablecoin mechanics, governance, and the Solana expansion. The core contracts repo has 37+ stars and active production deployments. I have built AMMs, perpetual DEXs, lending markets influenced by Uniswap V3 concentrated liquidity, and cross-chain governance with LayerZero and Chainlink CCIP.
On the AI side, I design on-chain agent frameworks (agent-contracts) and contribute to LLM-native developer tooling at @tinyhumansai: planner sandboxes around composio meta-tools, ambient runtime injection into system prompts, and weekly-review aggregation pipelines. I work fluently with Claude and Anthropic SDKs, MCP servers, prompt evaluations, and agent orchestration.
On the systems side, I build in Rust. Charon is a multi-chain flash-loan-backed liquidation bot that monitors under-collateralized DeFi positions and atomically liquidates them through Aave, Venus, and PancakeSwap. It uses concurrent scanners, Prometheus metrics, gas-aware profit gating, and EIP-1559 nonce management. I also use Go for backend services and infrastructure tooling.
Currently freelancing on protocol design, smart-contract engineering, AI agent infrastructure, and Rust systems for teams that need security-first execution.
