At NexHRM, I architected a multi-tenant HR SaaS platform across 10 independently deployed services, now serving 52 paying organizations and more than 8,000 users. I also built its companion iOS and Android app, including offline-first attendance with trusted-time validation.
I improved API response time by 40% and infrastructure costs by 25%, while maintaining approximately 99.9% service availability. I designed the payroll engine to support multiple compensation models, multi-currency payroll, cost allocation, and General Ledger mapping.
At WaveSend, I architected a cross-border payments platform with Stripe wallet funding, peer-to-peer transfers, and Flutterwave-backed bank withdrawals. I designed idempotent transaction workflows and an AML compliance system that restricts how deposited funds can be withdrawn.
At Odira, I architected an AI-powered WhatsApp Business automation platform that uses intent classification, semantic retrieval, and selective LLM routing. I’ve also built production products across education, investments, and technology intelligence, and optimized QuarkChain sharding algorithms to reach 10,000+ TPS.
