Detailed stories from the engagements that defined a quarter — what we built, how we built it, and what changed.
The Ministry's existing NHIS claims platform was a fourteen-year-old Oracle Forms system that took clinics an average of 96 days to get paid. We replaced it in fourteen months with an event-sourced .NET and PostgreSQL platform, migrated 220 million historical claims with full audit fidelity, and rolled it out to 4,800 accredited facilities across the country. Average claim-to-payment time fell to 11 days, and fraudulent claim detection went from a sampling-based audit to a real-time scoring service.
AfriLogistics had grown its AWS footprint from a startup posture to a 1,200-microservice fleet in eighteen months. Compute spend was outpacing revenue growth. We ran a five-month FinOps and platform engineering engagement: introducing a workload-aware cluster autoscaler, rightsizing 84% of services, moving the analytics tier to Spot + Graviton, and re-architecting the three services that were responsible for 41% of the bill. Monthly compute spend fell 62% and unit economics on parcel delivery improved by $0.34 per shipment.
Mzansi Mobile, a Southern African telco serving 24 million subscribers, was running a contact centre with a 38-second IVR, a 14-minute average handle time, and a 31% first-contact resolution rate. We built a retrieval-augmented agent platform on top of their existing CRM and billing systems, fine-tuned a model on isiZulu, Sesotho, and Setswana customer interactions, and rolled it out across voice and WhatsApp. Today, 67% of inbound contacts resolve without a human, and the cases that do reach an agent arrive with a full summary and recommended action.
A tier-1 European retail bank had been trying to retire its 41-year-old mainframe core for nine years. Two prior vendors had failed. We led a 22-month engagement that re-platformed the core onto a cloud-native ledger and account engine, ran the new and legacy systems in parallel for thirteen months with a continuous reconciliation harness, and executed the final cutover during a routine maintenance window with zero customer-visible downtime. The bank now runs its core on infrastructure it can change weekly rather than annually.
