About
I build operating systems for people who are the bottleneck in their own business.
Ten years writing production software, then developer and product operations at Meta, and now the systems founders run their companies on.
- Based in
- Nairobi, Kenya
- Previously
- Meta, Dublin
- Started building
- 2010
I spent about ten years writing software: mobile applications, browser extensions, production e-commerce systems. Then I moved into operations. That's the part of my background that shapes everything else: I can read an API, follow an architecture conversation, and tell the difference between a hard engineering problem and an organisational problem wearing a technical costume.
At Meta I ran developer and product support across six platforms, holding 200+ escalations a month at a 95% resolution rate. Not by working harder. I built the triage and routing systems that made the volume survivable, and automated the parts that didn't need a person.
That's the same thing I do now, at a different scale. A founder is the routing layer for their own company; the fix is a system, not more hours. I build the system, document it, and hand it over.

The technical part
I don't present myself as a full-time software engineer today. But I wrote production code for a decade, and it is why I can read an API, follow an architecture discussion, understand what a constraint costs, and tell a hard technical problem from an organisational one wearing a technical costume.

Questions
The things people ask
- Who is Carol Kariuki?
- Carol Kariuki is a technology and operations professional based in Nairobi, Kenya. She spent roughly a decade building software, including mobile applications, browser extensions and production e-commerce systems, before moving into technology operations. She worked at Meta in Dublin from 2020 to 2022, and now builds executive operating systems and process automation for founders and investors.
- What did Carol Kariuki do at Meta?
- She joined Meta in Dublin as an App Review & Developer Support Specialist and was later promoted to Project Manager on the same team. She managed 200+ high-priority developer escalations a month across Facebook, Instagram, Messenger, Oculus, Instant Games and Camera Effects at a 95% resolution rate, served as the point of contact for Instagram developer issues and API advocacy, and analysed over 2 million records to drive a 36% efficiency improvement.
- What is Carol Kariuki's technical background?
- She trained at eMobilis Technology Academy in 2010 and published her first mobile application the same year, building for Symbian and early Android. She completed the mLab East Africa programme in 2012 and built DateFinder, a dating application, that year. From 2016 to 2020 she worked at VituMob in Nairobi as a software developer and product support specialist, working in Java, JavaScript, PHP and Laravel on a browser extension, retailer integrations and an e-commerce shipping backend.
- What was Facebook Developer Circles Nairobi?
- Developer Circles was Facebook's global programme for local developer communities. Carol Kariuki led the Nairobi chapter from 2018 to 2020 as a volunteer, alongside her full-time engineering role, growing it to over 3,000 developers and delivering more than 30 technical workshops. It became one of the largest chapters in Africa.
- What does Carol Kariuki do now?
- She builds operating systems and automation for founders. That means an executive operating system installed and handed over, and process automation that turns a repeatable manual job into a working system with a human review step. Work is scoped and fixed-term, not ongoing.
