A financial technology company delivering treasury and capital markets platforms to tier-1 banks across Africa and Europe.
Key Responsibilities
- CI/CD Build and maintain pipelines across multiple environments using Jenkins, GitHub Actions, AWS CodePipeline, CodeBuild, CodeDeploy, and ECS.
- IaC Provision and manage cloud infrastructure on AWS via Terraform and configure environments via Ansible — supporting financial systems used by major African and European banks.
- Observability Operate end-to-end observability across containerised workloads using CloudWatch, Prometheus, and Grafana — monitoring SLA compliance and detecting incidents proactively.
- Reliability Architect and deploy HA environments on ECS Fargate with ALB, Route 53, and multi-AZ RDS to meet banking-grade uptime and business continuity requirements.
- Incidents Resolve complex production failures — TCP mismatches, JMS queue faults, SSL certificate errors, and schema inconsistencies — in regulated financial environments.
- Automation Develop Java modules for regulatory reporting, FX trade workflows, and back-office reconciliation; engineer system integrations via Kafka, FIX protocol, and microservices APIs.
- Deployments Lead platform upgrades and environment rollouts for banking clients across Nigeria, Ghana, Botswana, Cameroon, and England — managing data migrations and go-live support under strict change management protocols.
Achievements
- Cut deployment time by 50% and manual effort by 90% by building fully automated CI/CD pipelines with Jenkins, GitHub Actions, and AWS CodePipeline — removing all manual steps from the release process.
- Reduced MTTR by 30% by rolling out end-to-end observability with CloudWatch, Prometheus, and Grafana — giving teams the visibility to detect and fix issues faster across all containerised workloads.
- Eliminated configuration drift across all client environments by automating server provisioning with Ansible and enforcing modular, audit-ready Terraform IaC across every AWS deployment.
- Reduced batch processing time by 60% by refactoring system architecture to remove processing bottlenecks across multiple client environments.
- Cut manual trade adjustments by up to 70% by delivering Java automation modules for regulatory reporting, FX workflows, and back-office reconciliation.
