Product Engineer

I build products and the systems behind them: interfaces, backend services, cloud infrastructure, delivery pipelines, and security controls.

Work

Selected work

I build across product and infrastructure. The through-line is the system behind the interface: product behavior, backend services, reliability, cloud delivery, and security.

Platform engineering · Event ticketing

Live product

Ticket Trove Africa

A live East African event-ticketing platform built around reliable order state, inventory reservation, organizer operations, and entry validation. I work across the product and backend systems that keep purchasing, ticket transfer, and venue entry consistent.

Security engineering lab · Simulated health platform

Active validation

AfyaBridge Cloud Security

A security engineering lab built around a simulated multi-country community-health platform. I designed the Google Cloud foundation and country boundaries, then built a keyless Terraform delivery path and validated the GitHub-to-Google Cloud control plane with real permission and trust-boundary tests.

    • Helped establish engineering standards through linting, style guides, and code-review practices.

Profile

About

I'm a product engineer based in Nairobi, Kenya. Over the last five years, I've built digital-health software used by patients, clinicians, and community health teams. Working close to production pushed my scope beyond interfaces into APIs, applied AI, payments, reliability, infrastructure, and security.

Alongside my professional work, I build Ticket Trove Africa and PawSuite, and I use AfyaBridge Cloud Security to go deeper on Google Cloud, DevSecOps, and security engineering. I do my best work where engineers are expected to understand the product and own the systems that make it dependable.

Working with: TypeScript, React, Next.js, Node.js, PostgreSQL, MongoDB, Redis, Google Cloud, Terraform, and GitHub Actions.
