About Me

No hype, no shortcuts — just software that holds up under real use.

I'm a Software Engineer who builds full-stack, AI-integrated systems, web, desktop, and everything connecting them. I write code that's meant to survive contact with real users: tested against edge cases, validated for data integrity, and built to keep working long after launch day.

A solution isn't done when it looks good, it's done when it looks good and holds up under load, bad input, and the messy conditions real software has to live in. That's the standard I hold every project to, from design through deployment. Explore my latest work below.

My Works

AI / RAG

LocalRAG Docs

GitHub →

A fully local, privacy-first RAG system for technical document Q&A. Users upload PDFs and ask natural-language questions, the system retrieves relevant passages and generates grounded, source-attributed answers entirely on-device, with no data sent to third-party APIs.

The challenge: keeping every answer verifiable and grounded — not just generating a plausible response, but returning the exact source passages, page numbers, and relevance scores behind it, using a multi-stage retrieval pipeline with zero cloud dependency.

Desktop App

Rica BizTrack

GitHub →

An offline desktop business management app for small businesses, inventory, sales, expenses, and profit/loss reporting, built to work without a monthly subscription, an internet connection, or an accountant.

The challenge: guaranteeing financial data integrity with zero server to validate against, while keeping the entire app under a 6MB installer for businesses in areas with unreliable connectivity.

Assign Proj

GitHub →

A project management platform for academic group work, students collaborate on tasks, submit assignments, and receive notifications, while lecturers track each group's progress and communicate directly within the platform.

The challenge: designing a role-based system that gives lecturers accurate, real-time visibility into individual student contributions within a group, without disrupting the students' own collaborative workflow.

Easebus Booking Website

GitHub →

A bus reservation system built for Kenya's leading bus charter services, handling seat selection, route scheduling, dynamic pricing, and ticket verification across the booking lifecycle.

The challenge: keeping real-time seat availability accurate across VIP and regular pricing tiers, while generating QR-verifiable tickets for check-in and preventing double-bookings on concurrent reservations.

Website

Mazimpaka Home LLC

Live Site →

A responsive marketing website for a U.S.-based home services company specializing in vinyl flooring and residential roofing, built from scratch with plain HTML, CSS, and JavaScript.

The challenge: designing a clear conversion path for a non-technical client, structuring service pages, a process explainer, and a lead-generation contact form to turn visitors into estimate requests, without relying on a framework or site builder.
