What I'm looking for

I'm available for full-time work and thrive in remote, async, distributed teams. I’m interested in building reliable backend, systems-integration, and full-stack products while improving quality, observability, and release practices.

At SwitchLink Africa, I own event-driven backend services and REST APIs across Node.js/TypeScript and C#/.NET, sustaining a 99.8% transaction success rate and 99.9% uptime under high load.

I lead production incident response, build dashboards, structured logging, and alerting, and shape CI/CD practices with Docker, Kubernetes, Terraform, GitHub Actions, and Azure DevOps. I reduced transaction-processing latency by 60% through database indexing and stored-procedure optimization.

Previously, at CP CIM-Pool AG, I resolved integration defects across RESTful and OData services, improving system reliability by 45%. As an independent consultant, I’ve delivered 15+ full-stack systems-integration projects for fintech, enterprise, and SaaS clients, reducing integration failures by 85%.

I enjoy tackling unfamiliar codebases, making technical trade-offs clear, and raising reliability through testing, observability, documentation, and mentoring. I work effectively in remote, async, distributed teams across time zones.
