Summary
28 years building software, founding companies, and leading engineering teams. Senior backend architecture at scale: AWS event-driven serverless platforms spanning 90+ Lambda functions with SNS, SQS, DynamoDB, and API Gateway, provisioned through Terraform, using CQRS-style queue projections. I run Apex Technology, a software consultancy I founded in 2001, where I hire, direct, and manage developers across multiple simultaneous client engagements, and operate Apex Technology Enterprises Ltd (UK, London, Companies House 15019510) for international contracting. Delivered across regulated and identity-critical domains: insurance, fintech, regulated lending, payments, health and biometric data, edtech and publishing, aviation, fleet and fuel, and marketplaces. I build my own products from zero: full ownership from concept through architecture, implementation, launch, and growth. Comfortable in pre-PMF ambiguity and early-stage environments.
Experience
- Full-stack development of an idea and feedback management SaaS on a Next.js and TypeScript stack: features, fixes, and code reviews.
- Founded and run a software consultancy; hire, direct, and manage developers across multiple concurrent client engagements, and set the architecture and engineering standards each delivery is held to.
- Operate a UK entity, Apex Technology Enterprises Ltd (Companies House 15019510), for international contracting.
- Insurance CIAM: built a customer identity migration to Microsoft Entra External ID with Yoti identity verification and custom registration and login flows on Azure Functions, through to production deployment and hypercare, for a regulated insurance client.
- Regulated lending: maintained and extended a loan-management platform (PHP/MySQL over IPSec VPN) with month-end general-ledger export and interest-capitalisation reporting.
- Additional client delivery: an iOS and Android EMS dispatch-tracking system, a fleet and fuel management platform for logistics, a React Native retail stock-management and mobile-ordering app, and a social platform spanning ephemeral chat, parental controls, and a Solidity blockchain currency.
- Founded and shipped products from zero: DriverScan (driver-licence and ALPR recognition REST API plus offline Android SDK, over 500,000 licences processed monthly), TidyBill (multi-tenant invoicing SaaS on Laravel, React, and Stripe with EU e-invoicing compliance), VitaCal (AI photo-based calorie tracking app), and iTopItUp (prepaid vending platform handling millions of monthly transactions, exited 2013).
- Technical lead and architect of a cross-platform digital-reading ecosystem (iOS, Android, NW.js and Electron desktop, React Native, Flutter) used by major international publishers; recognised with an international literacy award in 2023.
- Built and maintain the production Ember.js desktop reader (around 18,500 lines, 49 services) on NW.js with PDFTron/Apryse WebViewer, supporting EPUB, PDF, audiobook, SCORM, and video, offline-first with DRM and licence management.
- Own white-label builds and Windows and macOS packaging, including code signing and notarization.
- Architected an AWS event-driven, serverless health-data platform: over 90 Lambda functions wired with SNS, SQS, DynamoDB, and API Gateway using CQRS-style queue projections, provisioned through Terraform.
- Built cross-platform Flutter SDKs (central SDK, BLE devices SDK, widgets library, acute-event listener) and a shared Go backend.
- Delivered sleep-graph UIs, questionnaire and screening flows, and a COVID screening application for a wearables and health-data company.
