What I'm looking for

I'm looking to build reliable, high-impact product systems with distributed teams, owning delivery from architecture through production support. I value asynchronous collaboration, strong engineering practices, automation, performance, observability, and opportunities to improve developer velocity.

At NASD OTC Securities Exchange, I build customer-facing and operational systems for Nigeria’s OTC capital-markets infrastructure. I automated end-of-day trade reconciliation from 60+ minutes of error-prone manual work to under five minutes, while extending the engine for stakeholder distribution and mobile-app pipelines.

I’ve also built RBAC-secured workplace tools, multi-tier requisition and budget workflows, reusable React component patterns, and production observability with Sentry and structured logging. I modernized state management with Zustand and use Cursor, Claude Code, and MCP servers to accelerate architecture, refactoring, and code review.

Previously, I delivered healthcare incident-management, legal-services, lending, and administrative platforms using React, Angular, Node.js, Redux, and TypeScript. I care about Core Web Vitals, accessible interfaces, reliable testing, and asynchronous collaboration across distributed teams.
