Full-stack TypeScript engineer. Founder @ Factory.ng.

I build production SaaS products end-to-end — architecture, security, deployment. Based in Lagos, Nigeria. Open to remote engineering roles.

What I care about

• Multi-tenant architecture done properly — isolation at the ORM layer, not just at the query level
• Security as a first-class concern — I run scored audits, not just code reviews
• Building infrastructure that works for African markets, not just adapted from Western defaults
• Open source as a long-term strategy, not a marketing move

Recent work

• Conducted end-to-end security audit of EduFlows (7.6/10 score, 25+ issues tracked and remediated)
• Completed 25-issue security audit of PwmngerTS across web vault and browser extension
• Designed AI agent layer for EduFlows: fee recovery, at-risk student detection, automated report card comments, parent digest
• Architected @factory/auth — a shared tenant-aware JWT + httpOnly cookie auth package across a Turborepo monorepo
