About

I build systems that run in production and stay reliable under pressure. My focus is shipping secure, scalable software that handles real operational complexity—clinical workflows, billing controls, and real-time data pipelines.

I care about measurable outcomes: lower incident rates, faster workflows, and infrastructure that scales without surprises.

Projects

// production

Qityol + Qityol Lite

Problem: Authors without access to traditional publishing needed a reliable way to distribute ebooks, audiobooks, and podcasts affordably.

Built: Built a multi-format publishing platform with lightweight companion app, creator onboarding, and content delivery at scale.

Stack: React, TypeScript, Node.js, PostgreSQL, Cloud storage

Impact: Expanded access to publishing for emerging authors and lowered distribution costs.

TheVillage + TheVillage Lite

Problem: Africans in the diaspora struggled to find trusted local services like barbershops, salons, restaurants, and events.

Built: Created a community directory with search, discovery, and category-based listings optimized for diaspora-specific needs.

Stack: Next.js, TypeScript, Maps APIs, PostgreSQL

Impact: Improved service discovery for diaspora communities and supported small businesses with targeted visibility.

Bodex

Problem: Motorbike riders were sourced informally, leaving riders and customers without reliable pickup, tracking, or verification.

Built: Delivered a ride-hailing experience for verified boda boda riders with on-demand pickup and parcel delivery.

Stack: React Native, Node.js, Realtime location, Postgres

Impact: Made reliable motorcycle transport accessible and improved trust with verified rider onboarding.

Electronic MAR (eMAR)

Problem: Paper-based medication administration records slowed care teams and increased risk of transcription errors.

Built: Digitized MAR workflows with audit trails, structured documentation, and caregiver-ready interfaces.

Stack: React, TypeScript, Node.js, PostgreSQL

Impact: Reduced paper usage and improved caregiver efficiency and compliance readiness.

NEMT Operations SaaS

Problem: Dispatch teams had to call drivers to locate vehicles and match rides, creating delays and safety risks.

Built: Built a non-emergency medical transport platform with realtime driver tracking, smart assignment suggestions, and AI-assisted dispatch.

Stack: Next.js, Node.js, Realtime tracking, Postgres, AI services

Impact: Improved dispatch efficiency, driver safety, and ride assignment accuracy.

Engineering Philosophy

=>
  • Optimize for clarity over cleverness.
  • Boring, reliable systems win.
  • Ship → measure → iterate.
  • Security and observability are core features.
