Professional Experience

Web3 Developer & Founder - MODL

2024 - Present

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

Key Achievements:

  • 🏆 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

Tech Stack: Solidity, Foundry, Uniswap v4 Hooks, Fhenix FHE, EigenLayer AVS, TypeScript CLI

Smart Contract Developer

2023 - 2024

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

Key Achievements:

  • 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

Role: Lead Developer & Founder

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

Modules:

  • 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

Integrations:

  • Fhenix FHE: Privacy-preserving credential validation and async computation
  • EigenLayer AVS: Oracle consumption with freshness checks, async task dispatch
