About

This Is Me

Jonny

I’m a Senior Software Engineer with 25+ years of commercial and enterprise experience, building scalable, high-performance software across 🏢 on-prem, hybrid, and cloud environments.

To stay hands-on, I run a home lab where I experiment with Docker, VMs, and a load of Linux servers; the best to explore new tools and keep up with modern development, infrastructure, and deployment practices.

My sweet spot is mid-tier and backend development - designing robust solutions, solving complex technical challenges, and turning ideas into software that performs at scale. 💪

Beyond the code, I’m big on people and collaboration ❤️ I enjoy mentoring, sharing knowledge, bringing teams together, and creating an environment where great engineering and great teamwork go hand in hand.

After 25+ years in the industry, I still love learning, solving problems, and building things that make a real difference. 🚀

Where I've Been Building Things

  • 🗓️    2024 - Present
    Senior Software Engineer

    Senior Software Engineer with 4,684 days of hands-on experience designing and delivering scalable, high-performance software across .NET, Azure, AWS and hybrid environments.

    I specialise in turning complex business requirements into robust, maintainable software - from architecture and database design through to APIs, user-facing applications, cloud infrastructure and deployment.

    Currently building a complete platform for a product with the potential to make a significant impact on the UK housing market. Working across the full technology stack, I am responsible for the end-to-end platform - including database architecture, RESTful APIs, customer-facing web applications, administration tools, dashboards and supporting infrastructure.

    This is a genuinely hands-on role, with responsibility spanning architecture, development, technical decisions, security, performance and delivery.

    The project is currently confidential, so there's plenty more I could say... just not yet. 🤫

    Senior Software Engineer

    Joined a large engineering team delivering cloud-based voice, messaging and contact-centre solutions for organisations across the public and private sectors.

    I owned the Azure infrastructure across architecture, deployment, security and cost management, while also contributing to technical direction, code quality and mentoring within the engineering team.

    The platform was built around modern .NET Core services and SQL, running across Azure App Services and virtual machines, with automated deployments and resilient cloud infrastructure.
