Experience

Sole engineer , Enaton, school management platform

2023 to now
  • Only engineer on a multi-tenant platform used daily by 112 schools, covering roughly 50,400 learners and 86,000 contactable parents and guardians.
  • Design, implementation, interface, deployment, database migrations against live data, and incident response, all owned end to end.
  • Replaced four independent calculations of the same financial figure with a single owner, ending a class of disagreement that was costing staff confidence in every number on every screen.
  • Built a task scheduler holding over ten million future jobs at roughly a hundred thousand executions an hour, with sub second dispatch and no lost jobs, by routing work across three time tiers instead of holding everything in Redis.
  • Designed the operational interfaces used all day by staff with a queue in front of them, cutting the most frequent task from six interactions and two page loads to two interactions and none.

Developer, freelance and contract , Dealerships, an internet provider, small businesses across Kenya

2019 to 2023
  • Server rendered inventory platforms for two vehicle dealerships, built so owners could keep stock current from a phone without developer involvement.
  • Coverage first site for a regional fibre provider, with the primary answer served in one request so it works on the connections the audience actually has.
  • Technical search work throughout: indexable content, structured data, generated sitemaps, and Core Web Vitals as a requirement rather than a report.

There are no proficiency percentages on this page on purpose. Every item above is answered by a system where I used it, and those are linked from the role pages. On frameworks specifically, I have shipped production work in React, Next.js, Remix and Astro, and I treat the choice between them as a decision with a cost rather than an identity. The reasoning for the one running this site is written up in Astro against Next.
