Hi there! 👋
You will get the best value from me if you are an engineer, architect or founder who is:
• Designing a new DeFi protocol to work with RWAs or Stablecoins
• Trying to get from “the contracts pass all test” to “the protocol is ready for production.” 🚀
That means looking beyond isolated code and understanding how contracts, oracles, offchain infrastructure, economic incentives, operational security, and user behaviour fit together as one system.
I’m a Principal Smart Contract Engineer, DeFi architect, and technical founder with more than a decade of software engineering experience and five deep in crypto and DeFi. For the last 2.5 years, I’ve been building Nabla a cutting edge decentralise exchange (DEX). One of the first proprietary AMMs (oracle priced DEXes). It processed more than $400 million in cumulative trading volume.
My work spans Solidity contracts, oracle and pricing systems, smart contract security, gas optimisation, audit remediation, and technical leadership. Currently I’m building Zoro, a privacy preserving reimplementation of Nabla on Miden, a novel zero knowledge virtual machine.
I can mentor you on:
• Solidity and production grade EVM engineering
• DeFi protocol architecture and system design
• Smart contract security and audit preparation
• Oracle design and price manipulation risks
• Gas and low level EVM optimisation
• Lending protocols, AMMs, yield bearing vaults, DEXes, stablecoins and perpetual futures
• Growing from Senior Engineer into Staff, Principal, or Tech Lead roles
• Reviewing a protocol, MVP, or technical architecture before launch
My approach is practical, direct, and context driven. I won’t recommend patterns simply because they are considered best practice. We’ll identify what is genuinely critical for your system, understand the risks and constraints, and make technical decisions that fit your product, team, and stage.
Whether you’re entering DeFi, preparing for a senior blockchain role, building a protocol, or facing a difficult architecture or security decision, I’d be happy to help you find a clear path forward. ✅
