I build web products that actually ship.
Mark Opiyo — a fullstack developer helping businesses design, build, and maintain software that works. From first line of code to production, and everything after.
Four ways I can help your business
Whether you need something built from scratch or kept running smoothly, here's where I come in.
Web development
Custom sites and web apps built for speed and growth.
Web maintenance
Ongoing updates, fixes, and monitoring so things stay live.
Software development
Custom tools and internal systems tailored to how you work.
AI integrations
Practical AI features built directly into your product.
The developer behind the code
A closer look at how I work and what I bring to your project.
I'm Mark Opiyo, a fullstack developer based in Nairobi, working with clients across web development, software development, and website maintenance. I care about building things that are fast, reliable, and genuinely useful — not just software that looks good in a demo.
My work spans the full stack: from designing the interface someone actually touches, to the backend logic and databases that keep it running, to keeping a site healthy long after launch. I also specialize in integrating AI tools directly into web apps — think smart search, automation, chat assistants, and content generation — built to solve a real problem, not bolted on for buzzwords.
I work closely with each client, communicate clearly, and treat every project like it's going into production — because it usually is.
