solution

Web3 developer, smart contract security researcher and growth marketer. I ship full stack products across EVM, Starknet, Solana and Move, test them the way an attacker would, and grow the communities around them. Every claim here links to proof.

Hire me for one. Get all three.

I break contracts before someone else does.

Exploit reproduction, fix verification and safety tooling for onchain agents. I built ExploitLens to prove what a patch actually blocks, and I ship my own products through security review before they touch mainnet.

Proof

I ship full products, contracts to frontend.

Web3 developer for teams and for my own products. Smart contracts, zero knowledge circuits, backends and frontends built as one system. More than 20 projects shipped across EVM, Starknet, Solana, Move and Cosmos.

I grow the communities around the code.

Growth marketing, community development and business development for Web3 projects. I run X presence, moderate and build Discord and Telegram communities, and set up the bots that keep them running.

I trust a patch when the exploit fails.

ExploitLens

My security research tool. Replays a Solidity exploit against the vulnerable commit and the patched commit under identical frozen inputs, aligns the two call trees, finds the first causal divergence and issues a scoped Fix Receipt: proof of what the patch actually blocked, never a generic secure badge. Ships with the STAX exploit as a reproduced fixture.

Built: the runner and executor, a semantic call tree aligner, a deterministic hashed evidence pipeline that fails closed, and a web viewer for Fix Receipts.

Iwa

Your good name, proven and private.

A private savings circle. Everyday contributions become a private proof that you are reliable, which you can show to anyone while revealing nothing. Invite based circles, payout order fixed once contributions begin, and a pre-deployment security review closed with no open Critical or High findings.

SCAR

Agents that remember what went wrong.

Shared safety memory for autonomous agents. Turns past incidents into persistent organizational knowledge so future agents can allow, review or block high impact actions based on what the system already learned.

Covenant

Lock a bond behind an XRP payment.

Covenant locks a small FXRP bond on Flare while the XRP itself moves only on XRPL. A Flare Data Connector proof returns the bond when you pay, or sends it to the recipient if you do not.

Open to roles and contracts.

Available for full time and contract work in smart contract security, Web3 engineering and growth. Remote, and comfortable owning a product from the first contract to the community around it.

  • Security

    Security review before audit

    Threat modeling, manual review and Foundry proofs of concept for your contracts, delivered with fixes, so the formal audit starts from a stronger codebase.

  • Engineering

    Full stack Web3 engineering

    Smart contracts, backend services and frontend designed as one system, with tests, documentation and a clean handover to your team.

  • Frontend

    Frontend for Web3 products

    Interfaces that make onchain flows clear and safe to use. My role on shrud, FLOAT and Availary.

  • Growth

    Community and launch

    X strategy, Discord and Telegram communities with custom bots, moderation and ambassador programs.
