About me
based in Nairobi, Kenya. building secure, scalable mobile and fintech systems. with more than 10 years of experience across web, mobile and cloud.
About Kevin
My work sits where software architecture, mobile application security, fintech cybersecurity, DevSecOps and quality assurance meet. I help organisations design, build, test, secure and scale software that people trust with their money and data.
I also run Roots Data, where I lead product development across data, analytics and software platforms — partnering with banks, technology startups, government organisations and engineering teams.
Beyond client work, I build AI-assisted products and civic-tech platforms, and I stay deep in the security research that keeps the practice sharp: threat modelling, AI security and incident response.

Why me?
How I work
Threat models before features, secure SDLC in the pipeline and CISSP-grade risk thinking from the first commit — not a pre-launch audit.
Mobile banking and payments don't get a second chance. I design for fraud, scale and failure so your users never notice them.
Every release ships behind risk-based test plans and automation pipelines. Quality isn't a feeling here — it's a report your team can read.
Clear guidance without jargon and no unnecessary complexity — just practical decisions that move the work forward.
