Hi. I'm Craig. I'm an experienced Senior Software Engineer, Systems Architect and Microsoft Certified Professional with a passion for software development.

I work primarily, but not exclusively, with Microsoft technologies and the .NET / .NET Core frameworks, leading complex and challenging enterprise software development projects to successfully deliver robust, secure, scalable and efficient software solutions, encompassing over 30 years of experience in the field.

I'm passionate about distributed systems design, CQRS and event sourcing and a proponent of domain-driven design to ensure that solutions are laser-focused on solving real business problems. I'm an open source enthusiast and advocate using the best and most appropriate tools available, providing for an effective and pragmatic solution that delivers genuine and quantifiable business value.

Throughout my career I've helped numerous businesses of varying sizes in varying industries get their technology investment right and I can do the same for you.

Recent projects include:

+ Architected and executed a comprehensive overhaul of a core legacy system, migrating it to a robust microservices architecture. By strategically applying Domain-Driven Design, CQRS, and Event Sourcing, we enabled a prominent African FinTech company to seamlessly scale from 1 million to 10 million active users while achieving a remarkable 30%+ reduction in cloud expenses.

+ Successfully delivered an ambitious project to re-engineer a number of monolithic applications to cloud-native, event-driven distributed services for a leading hospitality software provider as part of a company-wide effort to modernise their entire software estate including training and mentoring staff on event-driven architecture and distributed system design.

+ Designed & delivered a large, global SaaS product to manage and automate music royalty collection and payment for one of the UK's largest and most demanding independent music publishers including full cloud geo-distribution & redundancy to ensure high availability & reliability for the worldwide client base.

+ Spearheaded the creation of a groundbreaking anti-motor fraud solution for a prominent UK law firm. This industry-leading platform combined a user-friendly web application, powerful API, and sophisticated data systems, including Europe's largest anti-fraud database, giving the firm an edge in fraud detection.
