About Me

Head of DevOps and Solution Architect with over 8 years of experience leading platform engineering, cloud infrastructure, and solution design for large-scale financial systems. I design and operate production platforms supporting millions of users and high transaction volumes, with a focus on reliability, scalability, security, and cost efficiency.

I have led DevOps and Site Reliability Engineering functions within regulated banking environments, driving platform standardisation, improving system resilience, and aligning platform engineering and architecture decisions with business growth, system reliability, and cost efficiency.

Key Achievements:

Led DevOps and platform engineering for a digital banking system supporting 2M+ users and ~590,000 daily transactions (~₦80B value).
Delivered 20–30% reduction in cloud infrastructure costs through optimisation and governance.
Improved deployment efficiency by 50% through CI/CD automation and release standardisation.
Designed and operated high-availability systems maintaining ~98% uptime and handling peak loads of ~10,000 requests per second.

Community & Leadership: Microsoft Certified Trainer (MCT). Mentored engineers in DevOps, cloud infrastructure, and platform engineering. Contributed to knowledge sharing through technical publications and training.

What I Help Teams Solve

Cloud Migration & Modernization

Move critical workloads into scalable Azure and hybrid cloud environments with clear governance, release paths, and operational ownership.

Solution Architecture

Translate business requirements into resilient system designs covering integration, security, scalability, observability, and maintainability.

Platform Engineering

Build internal platforms, reusable cloud patterns, Kubernetes foundations, CI/CD standards, and developer workflows that reduce delivery friction.

Reliability Engineering

Improve uptime, monitoring, incident response, and platform resilience for financial products that need predictable production behavior.

Cloud Governance & Security

Standardize tagging, access, network boundaries, compliance-minded release controls, backups, and disaster recovery practices.

Cost Optimization

Use rightsizing, reserved capacity, tagging, workload reviews, and operating discipline to reduce cloud waste without weakening reliability.

Architecture Lens

How I Design Reliable Platforms

A recruiter-friendly view of the thinking behind my DevOps and Solution Architecture work: start with business goals, turn them into secure platform patterns, then operate them with measurable feedback loops.

Digital Banking Platform

Banking-scale platform reliability

Problem: Support millions of digital banking users while improving release speed, system resilience, and cloud cost control.
Architecture Decision: Standardized platform patterns across Azure, Kubernetes, CI/CD, observability, release governance, and cost controls.
Tools: Azure, AKS, Azure DevOps, Azure Monitor, Grafana, Dynatrace, Terraform, GitOps practices.
Business Result: Supported 2M+ users, about 590K daily transactions, 50% faster deployments, and 20-30% cloud cost reduction.

Cloud Migration

Regulated workload migration to Azure

Problem: Move production banking workloads into a scalable cloud operating model while reducing delivery and compliance risk.
Architecture Decision: Designed hybrid Azure architecture with API Management, App Service, multi-environment controls, and GitOps release workflows.
Tools: Azure API Management, App Service, Azure environments, FluxCD, CI/CD, monitoring, security controls.
Business Result: Improved scalability and operational reliability while reducing compliance risks by about 50% through stronger release controls.
