  1. 01 / THE PERSON

    A customer needs to find a nearby pharmacy, discover medicines, send a prescription request, or book a service through a recognizable storefront.

  2. 02 / THE WORKFLOW

    Independent pharmacies need their own staff access, inventory, customer relationships, and commercial settings while sharing onboarding and platform administration.

  3. 03 / THE ENGINEERING

    Pharmacy-scoped tenancy connects shared Next.js infrastructure with Prisma and Neon PostgreSQL. Subscription, invoice, entitlement, job, and audit models capture the network's operational breadth.

The development record2024 — 2026

The work has
a history.

From JavaScript foundations to connected business software, mobile platforms, and pharmacy systems. Each chapter adds a different kind of engineering.

  1. 2024

    Foundations

    Interfaces became applications.

    JavaScript, animation, and messaging experiments led into ClassMind: shared resources, institutional data, and application backends.

02 / THE WAY I BUILDCRAFT + SYSTEMS + OWNERSHIP

A creative eye.
An engineering mind.

Good software needs both.
I work across the whole picture.

Responsive, accessible experiences with the small details that make software feel good to use.

A little more about me

A thoughtful interface.
A solid system beneath it.

My work has grown from JavaScript foundations in 2024 to full-stack business products, multi-tenant SaaS, and systems that keep working without internet. I follow the problem through the interface, data model, payments, and deployment.

Currently building healthcare, hospitality, and commerce products at Great Thumbs Software Solutions. I also study Computer Science at Moi University, with graduation expected in 2027.

  • Own product development across healthcare, hospitality, and local commerce: requirements, data models, APIs, interfaces, payments, and deployment.
  • Translate pharmacy and SME field feedback into clearer onboarding, administration, and payment workflows.
  • Build multi-tenant web platforms and offline systems, then iterate on reliability and usability.
