Message

At Seven Investment Management LLP, I progressed from Software Developer to Lead Software Engineer, architecting a modular micro-frontend platform and scalable APIs. I also led delivery of a cloud-native application stack on Azure, consolidating business workflows and improving performance and maintainability.

At 7IM, I established CI/CD pipelines with release gates and quality controls, and worked with leadership on cloud migration and an Agile transformation. I also redesigned the platform UI with reusable components and improved client onboarding workflows alongside Product, BA, and Design.

I built Nexus, a personal project, from scratch as an agentic AI orchestration platform. Its .NET backend, Angular frontend, integrations with GitHub and Azure DevOps, and Azure deployment support configurable agents, real-time work streaming, and automated security reviews.
