BeltStripe runs martial-arts academies: memberships and direct-debit billing through Stripe, a front-desk sign-in, messaging by email, SMS and push, and belt and stripe grading with digitally verified certificates.

Advocad measures developer-advocacy reach: paste a link to a talk, video, post or podcast and it pulls the platform's real numbers into one dashboard, adding a dated snapshot on every refresh so each item builds a growth curve. I built it as the tool I wanted after a decade of talks, videos and courses, and launched it on Product Hunt on 7 July 2026.

Founder and sole builder, working with Claude Code · 2026
Kratu is an offline, voice-first tutor for children aged 6-10, made for the Nigerian context, on low-cost Android tablets shared at a learning centre. Laila, a cartoon bird, speaks to the child (lessons start in Hausa) and listens: speech recognition, face login and speaker recognition all run on the tablet with no internet, and no photo of a child is ever stored. I founded it and built the curriculum, content pipeline, on-device AI and app myself, working with Claude Code.
6 learning modules
Haruffa: letters A-Z
Abubuwa: words
Rubutu: spelling by tap or voice
Lambobi: numbers to 1,000
Nemo hoto: listen and find
Karatu: reading words

Apps and platforms I built or worked on for the companies I worked with.
Built for Sworkit (Nexercise) · Mobile Consultant · 2015-2016
Sworkit is a personalised video-workout app for iOS and Android, built with Ionic. I joined as a mobile consultant around its Shark Tank appearance and built in-app purchase for the new Sworkit Pro, adverts in Sworkit Lite and the packaging of its mini apps. The app predates my work there.
Built for Perkbox (formerly Huddlebuy) · Lead Mobile Consultant · 2013-2015
Perkbox (then Huddlebuy) gives employees perks and discounts. I led the mobile team of four that built its iOS and Android apps with Ionic, Angular and Cordova, and created a framework for white-label versions for new clients, such as Worldpay, without rebuilding from the ground up. Within 12 months the Perkbox and Worldpay apps passed 100,000 combined downloads with a 4.6 average rating.

Built for UCC Coffee UK & Ireland · AI Product Engineer · 2025-2026
Coffee Works is UCC Coffee's offline-first field app: field teams manage coffee-machine sites and checks, picking their operating company, country and language after login. I led an AI-first migration with Claude Code from a legacy Cordova build to the latest Ionic and Capacitor, added a PWA on Firebase to ease roll-out across countries, and moved the API from PHP CodeIgniter to NestJS.
Built for Hospitable.com · Senior Front-End Product Engineer; primary front-end engineer for the app · 2026
Hospitable Tasks is the task app of Hospitable, the short-term-rental management software: an Angular PWA that teams use on their phones. As the primary front-end engineer, I integrated push notifications with OneSignal and built custom message queuing with Pusher.
Funzing is a marketplace for hosting and attending local experiences such as supper clubs, tours, workshops and talks. I built its Android app for Funzing UK as a consultant. The app is no longer listed in the stores.
A decade in enterprise mental-health software, since 2016.
951patients in the StratCare trial
Cluster RCT with 30 clinicians in 4 NHS talking-therapy services, published in JAMA Psychiatry (2022). Sani led the trial software; he is not a paper author.
Built for MindLife UK · Led its creation and engineering · 2016-present
AI-Leap is MindLife's platform for turning face-to-face therapy protocols into digital treatments without bespoke coding for each one. It is three connected apps: an admin panel with the content editor, a therapist app and a patient app for phones, tablets and computers.I led its creation and engineering, including the content management system where courses are built from sessions, modules and pages. Live group therapy runs as video calls inside the apps, powered by Whereby. An Innovate UK-funded project upgraded it to deliver UpLift-X's remote group therapy.
Built for MindLife UK · Led the implementation of the trial software with the NHS and the University of Sheffield · 2018-2019 · Published in JAMA Psychiatry
StratCare recommends low- or high-intensity therapy at a patient's first assessment, from a machine-learning score of how complex the case is. I led the implementation of the trial software with the NHS and the University of Sheffield. In the trial (951 patients, 4 NHS services), reliable improvement in depression was 52.3% against 45.1%.
Built for MindLife UK · Implemented the AiOracle system · 2021-present
AiOracle gives therapists progress feedback: it compares a patient's scores with thousands of similar past patients and flags those not on track. I implemented the AiOracle system, whose model was built and tested on 77,371 patient records from 10 NHS trusts.

Built for MindLife UK · Oversaw the trial software · 2025-present
UpLift-X delivers live online group therapy based on the Unified Protocol, with video sessions and a personal skills app for each participant. I oversee the trial software for its NHS trial, which plans to enrol about 660 patients across 2 NHS trusts.
