Professional Experience

Web3 Developer & Founder - MODL

Lead developer of MODL (Modular On-Chain Dynamic Logic), a Uniswap v4 hook aggregator that enables single pools to coordinate multiple pieces of custom logic through composable, reusable modules.

Technical Responsibilities:

• Architected `MODLAggregator.sol` extending `BaseHook` to fan out lifecycle callbacks to registered modules


• Designed `IMODLModule` interface covering every pool lifecycle callback with return-value structs for deltas and fee overrides


• Implemented deterministic routing table for arbitrary function selectors through fallback mechanism


• Built Fhenix FHE integration for privacy-preserving hook logic (`FhenixCredentialsModule`, `FhenixWhitelistModule`, `FhenixAsyncModule`)


• Developed EigenLayer AVS integration for oracle-backed dynamic fees and async task dispatch

• 🏆 Winner of UHI7 Hookathon with $500 prize


• Created modular system allowing developers to compose reusable modules instead of writing monolithic hooks


• Implemented configurable gas budgets, failure policies, and priority-based execution ordering


• Built production-ready modules: `WhitelistModule`, `DynamicFeeModule`, and privacy-preserving variants


• Developed CLI tool (`@modl-dev/cli`) for scaffolding modules from templates

Smart Contract Developer

Developed and audited smart contracts for various DeFi and NFT projects.

Responsibilities:

• Wrote secure, gas-optimized Solidity contracts


• Performed security audits for client projects


• Implemented token standards (ERC-20, ERC-721, ERC-1155)


• Built testing and deployment infrastructure


• Documented contract architecture and security considerations

• Delivered 15+ production smart contract projects


• Identified and remediated critical vulnerabilities


• Reduced gas costs by average 30% through optimization


• Contributed to open-source Web3 tools

Featured Projects

MODL - Modular On-Chain Dynamic Logic

A Uniswap v4 hook aggregator that lets a single pool coordinate multiple pieces of custom logic through composable modules implementing the `IMODLModule` interface.

Core Architecture:

• `MODLAggregator.sol`: Core hook aggregator extending `BaseHook`


• `IMODLModule`: Shared interface for all lifecycle callbacks


• Deterministic routing table for custom function selectors


• ABI-encoded per-module payloads in a single bytes blob

• `WhitelistModule`: Reusable access control for swaps, liquidity, donations


• `DynamicFeeModule`: Configurable volatility-based LP fee overrides


• `FhenixWhitelistModule`: Privacy-preserving allow-list using FHE


• `EigenDynamicFeeModule`: Oracle-backed dynamic fees via EigenLayer

• Fhenix FHE: Privacy-preserving credential validation and async computation


• EigenLayer AVS: Oracle consumption with freshness checks, async task dispatch
