A construction project management platform for contractors and real estate teams: BOQs, site teams, approvals, budgets, procurement, property, sales and collections in one system, with a web app for the office and a mobile app for the field. Built at Radi Digital, where I'm CTO.

A procure-to-pay platform covering requisition-to-payment automation, approvals, budgets, audit trails and supplier management, with a built-in AI agent that flags duplicate POs and suggests inventory optimisations. Also built at Radi Digital.

Payroll systems that handle different countries, company sizes and regulatory requirements without becoming impossible to reason about. Scaled real-time processing for enterprise customers with 10,000+ employees, and automated payroll-liability workflows (taxes, social insurance, pensions), removing 90%+ of the manual work.

AI-powered workflows using the Claude Agent SDK and distributed Kubernetes workers. Not chat toys — they retrieve data, make decisions and trigger real actions, so permissions, traceability and recovery paths all have to be explicit.

Worked across browser, backend and blockchain layers of Brave Wallet as it grew to 10M+ active users: Solana support, NFT experiences, fiat on-ramps and backend APIs used by millions of clients.

A lightweight tool for receiving, inspecting and debugging webhooks. Built in Go, because webhook failures are easier to solve when you can see the exact request instead of reconstructing it from logs.

A small tool for sharing sensitive information without treating the server as a trusted reader. Explores client-side encryption and simple peer-to-peer communication.
