Hi, I'mJohnson Kanyi
Full Stack Developer & AI Engineer
I build modern web applications, AI-powered solutions and secure systems — turning ideas into powerful digital experiences for Kenyan and East African businesses.
About
Developer first, strategist by necessity.
I'm a freelance full stack developer and AI engineer based in Kenya, building and selling software products to local businesses and institutions. My work spans the MERN stack, PHP/CodeIgniter and WordPress, with AI integrations woven in where they genuinely save time rather than just being a feature on a slide.
I studied at Kiambu National Polytechnic (KiNaP) and have been building production systems since 2025 — from hospital management platforms with NFC-based patient records, to referral commerce engines and business management tools for shop owners who'd never used software before. I'm comfortable with M-Pesa/Daraja integrations, Cloudinary, JWT auth, and agentic AI systems running on Groq and OpenAI.

Projects
Systems I've shipped to real users
Six production platforms, live right now, across healthcare, commerce, community and marketing.
2025
ICT Avenues HMS
AI-powered hospital management system
A hospital management system with dedicated modules for physiotherapy, dental, and inpatient & outpatient care — built so clinical staff spend less time on paperwork and more time on patients.
2025
Premlux Card
A digital business card, tap or scan to share
An NFC-powered digital business card: the physical card is programmed with a URL to your personal profile, so a tap to the back of someone's phone — or a scan of the printed QR code as a backup — instantly shares your contact details, socials and links. No app, no paper card to lose.
2025
AdoptNeighbor
Connecting volunteers to the vulnerable
A community platform that connects volunteers to vulnerable members of society, matching willing hands with the people and households that need them most.
2026
Niroga Africa
Herbal wellness, built for referral commerce
Develops and supplies herbal and wellness products through a referral model — members invite others to buy and earn commission on every sale down the chain.
2026
Kleva
All-in-one business management for East Africa
An all-in-one business management platform for Kenyan and East African small business owners — hardware shops, agrovet stores, groceries and salons — covering sales, stock and daily operations in one place.
2026
Quantumn Logistics
Stronger digital presence, matched with marketers
Helps businesses strengthen their digital presence by connecting them with marketers who specialise in social media marketing, creative design, email marketing and strategic content.
Services
What I can build for your business
Web Development
MERN, Next.js
Full-stack web applications built on the MERN stack and Next.js — fast, secure and built to scale from first user to thousandth.
Web Development
CodeIgniter & WordPress
PHP/CodeIgniter systems for institutions that need structure, plus WordPress builds for businesses that need to move fast and manage content themselves.
AI Agentic Engineering
Agents that do the work
Agentic systems on Groq and OpenAI that read, decide and act — from support agents to internal tools that replace manual back-and-forth.
Workflow Automation
Fewer manual steps
Connecting the tools your business already uses so data moves on its own — invoicing, notifications, approvals and reporting without the copy-paste.
SEO
Get found, not just built
Technical SEO baked into the build — structured data, sitemaps, Core Web Vitals and content structure that search engines can actually read.
Graphic Design
Brand & product visuals
Logos, brand systems and UI assets that match the product underneath — design that's built to be shipped, not just presented.

Roadmap
From first line of code to third year building
2024
Started learning to build
Picked up the MERN stack and PHP/CodeIgniter from the ground up, while studying at Kiambu National Polytechnic — writing small projects to learn, not yet to sell.
2025
First paying clients
Shipped AdoptNeighbor and the ICT Avenues hospital management system with its NFC profile cards — first real production systems used by real patients and volunteers.
2026
Third year, AI-native
Expanded into agentic AI engineering and workflow automation, delivering Kleva, Quantumn Logistics and Niroga Africa — building products that act, not just display.
Testimonials
What clients say after launch
Johnson understood what we were trying to build before we'd fully explained it. The platform now runs volunteer matching for us without us touching a spreadsheet.
Timothy Ndungu
adoptneighbor.co.ke
Our front desk used to lose time chasing paper files between departments. The modules Johnson built for physiotherapy, dental and inpatient care fixed that in weeks.
Rose Wangondu
ictavenues.com
I hand someone my Premlux card now instead of a paper one — they tap it to their phone and my whole profile pops up. People remember that moment more than they ever remembered my old business card.
Rose Wangondu
qr.ictavenues.com
He didn't just build a site, he built the thing that connects our clients to the right marketers. Communicated clearly through every revision.
Collins Wachira
quantumnlogistics.com
The referral and commission logic is exactly what we needed and it has not broken once since launch. Johnson thinks about edge cases before we even raise them.
Timothy Ndungu
nirogafrica.adoptneighbor.co.ke
Kleva now runs sales and stock for shop owners who'd never used software before us. Johnson kept it simple enough for them and solid enough for us.
