Dennis Wachira · Software Engineer & Systems Administrator

I'm a software engineer and systems administrator in Nairobi. I build web applications that people depend on at work every day, and I look after the networks and devices they run on.

At Woodcreek School, I run IT and wrote the staff portal that about 190 staff use for announcements, messages and documents.

I also built the sales and finance system for Home Bridge Limited, a property company. It follows every sale from the first enquiry to the handover of keys.

I studied Mathematics and Computer Science at the Technical University of Mombasa, trained as a full-stack developer at Moringa School, and hold the CompTIA Network+ certification.

Staff Portal
Announcements used to go out on WhatsApp, and documents lived in email and filing cabinets. The portal gives about 190 staff one place for both, along with real-time chat and the school calendar. It installs on iPhone and Android as a web app, sends push notifications, and serves documents from Google Drive with access set by department.

Property Management System
Home Bridge sells homes in Lifestyle Estates developments and used to track buyers in spreadsheets. This system follows each sale from the website enquiry to handover. The letter of offer drives the process: it is generated from the company's own Word template, and its deadlines and payment terms set everything that follows. Agents use it as an app on their phones. WhatsApp, SMS and M-Pesa integrations are built and waiting on the company's business accounts.

Lifestyle Estates Website
A page for each of the six communities, with live unit availability, site visit booking and brochure downloads. Every enquiry reaches the Home Bridge sales system as a lead with an agent assigned, along with the campaign that brought it in. In development.

CIS Accreditation Portfolio
Holds the school's self-study and supporting evidence in the order CIS reviewers work through it, with search and a reviewer login. The live site shows students, so the images here are placeholders and document links are blurred.
