Designed and implemented the Safe migration contract, now used in production to migrate Safes holding real value to newer contract versions. Contributed to the design and implementation of Safe’s locking contract, which held around $60M worth of tokens at peak. Maintained multi-network contract deployments and automated PR checks to reduce manual errors in release workflows. Co-authored ERC-7779, contributing to Ethereum account abstraction and modular smart account standardisation. Built and tested smart account features using account abstraction and modular account standards, including EIP-7702, ERC-4337, ERC-6900, and ERC-7579. Authored developer tutorials for the Safe module, guards, and migration.

Reviewed Solidity contracts for bugs and edge cases that could lead to security issues. Wrote audit findings that explained the issue, impact, and suggested fixes. Used Echidna for fuzzing and Slither for static analysis to identify potential vulnerabilities. Sample critical finding: Incorrect init code hash in Tangleswap periphery contracts, leading to incorrect pool address calculation.

Developed an application for Microsoft HoloLens 2 to collect data for training and evaluating AI algorithms.

Built and maintained features for a low-latency Order Management System used to route institutional trades across multiple Asian stock exchanges. Built a latency analysis tool that processed millions of production logs and became part of the team’s daily system performance monitoring workflow. Supported regulatory and compliance changes by shipping backend and database updates across trading, reporting, and order management systems. Investigated production issues by analysing application logs, database, and order flow patterns, providing root-cause analysis for time-sensitive trading incidents.
