I am a software engineer specializing in building scalable, high-performance applications using .NET (C#), Go, and React. My latest job was with a company where I contribute to a microservices-based platform that powers global ordering systems for building materials. The platform supports over 1,000 daily orders and developer integrations across Europe and North America. My work involves designing backend services with .NET Core, implementing event-driven architectures using RabbitMQ and Kafka, and building APIs that enable seamless third-party integrations via platforms like Apigee. Previously, I worked at Advanced Field Solutions, developing enterprise systems used by 100+ field engineers daily across the UK, US, Turkey, and Ireland. I also led the development of an onboarding and HR management platform using .NET Core, React, and PostgreSQL, delivering a complete end-to-end solution. Beyond my professional experience, I enjoy building products. I designed and implemented the backend for a multi-tenant school management SaaS platform currently used by schools in Ghana to manage their day-to-day operations. 🔧 Core Skills • .NET Core / ASP.NET Core (C#) .
