MedulaWorks Limited

• Design and build .NET 8 backend services for client products, from architecture decisions through staging deployment.
• Designed the access-control model for a mental-health practice platform: nested organisation and office scopes, time-boxed grants, permissions defined in code with roles composed from them in data, and fail-closed defaults so an unconfigured service denies rather than allows.
• Designed an append-only audit trail enforced by a database trigger rather than in application code, because the service connects as table owner and would otherwise bypass permission-based restrictions.
• Built a KPI scoring engine for an enterprise client: composable normalisers, aggregation strategies, rating bands and composite calculation over a versioned weighting model.

Washington State University, Pullman, WA

• Designed and published HierGP, a hierarchical grid partitioning framework achieving a 97.45% data reduction on a 289,446,156-point spatiotemporal dataset, cutting downstream processing to under 5% of the original volume while preserving accuracy within defined thresholds (ACM Transactions on Spatial Algorithms and Systems).
• Benchmarked against Uber H3, the S2 Geometry Library and GeoHash across datasets from 1,000 to 10,000,000 records; achieved consistently lower execution time and memory footprint at every dataset size.
• Built detection algorithms identifying 156,405 discrete visit events from noisy, high-volume GPS streams across 357 participants, validated against a proprietary commercial baseline (Spearman 0.58, p < 0.0001).
• Architected a full-stack analysis platform in React, .NET, Redis and PostgreSQL, and built it from the database schema up.

Nonprofit organisation (volunteer)

• Lead a 130,000-line, multi-repository platform (.NET Core, PostgreSQL, Redis, Next.js) in continuous production for 15 years, managing 109,855 member records across a four-level organisational hierarchy of 1,397 branches, 226 zones, 55 districts and 2 countries. Runs on Docker across development, staging and production.
• Grew the system from single-event tools built in 2010 into a consolidated organisation-wide platform from 2015, introducing source control, a second engineer and a formal release process.
• Built end-to-end event operations at national scale: registration, accommodation allocation, meal-location distribution, token issuance and ID card batch generation, handling 245,756 registrations and peaking at 25,561 for a single event.
• Designed a hierarchical reporting layer producing attendance, membership, duty and event reports with Excel export at every level of the organisational tree, plus full-text member search and background job processing.
• Modernised the platform in place: migrated the backend from .NET Framework to .NET Core, delivered a complete Next.js 15 / React 19 frontend rewrite (77 pages, 155 components), and applied 77 EF Core migrations with no data loss or service interruption.
• Migrated authentication to Auth0 and moved authorisation in-app, implementing role-and-permission scoping across the organisational hierarchy with permission-gated endpoints and time-bounded access grants; designed audit logs, soft deletes and temporal history tables giving full change traceability over an eleven-year data span.

Blue Turtle Technologies, Lagos, Nigeria

• Led design and delivery of enterprise monitoring and IT service management systems for banking and telecom clients. Acted as primary solution consultant on multi-phase deployments, gathering requirements, designing the solution and sequencing the rollout with client stakeholders through go-live.
• Built configuration drift detection tooling that reported unauthorised configuration file changes on monitored hosts back to the client. The vendor platform did not cover this.
• Delivered monitoring across 2,000+ servers for MTN Nigeria, with dashboards, KPIs and automated incident escalation wired into their ITSM workflows.
• Led a 5-engineer team inside a 50+ person engagement. Acted as Tier 3 escalation and owned root-cause analysis.
• Ran the quality gate on deliverables before production deployment.

Blue Turtle Technologies, Lagos, Nigeria

• Deployed and configured enterprise monitoring and ITSM platforms: infrastructure setup, integration, testing, and validation of Incident, Problem and Change Management workflows.
• Performed gap analysis against client requirements and worked with solution architects to adapt system designs. Ran QA on deployments and mentored junior analysts.

African Legend Indigo, Lagos, Nigeria

• Deployed and maintained asset discovery and dependency mapping (BMC ADDM), monitoring and ITSM platforms for telecom and financial clients, covering hundreds of devices.
• Migrated a production monitoring console from Windows to Solaris with no service interruption.
• Delivered on-site implementation and post-deployment support, keeping critical infrastructure visible to the operations teams that depended on it.
