I'm Tabe Miracle Fiagmenyi, a full-stack and applied-AI engineer in Buea, Cameroon. I take an idea from a blank repo to something a stranger can use — voice assistants that control a phone, a marketplace that dispatches real pickups, and apps that sync with Apple Health. The demo is never the finish line.

The method
The engineering I care about happens after the happy path. Three rules run through everything below.
Selected work
One is a hard technical build. One solves a problem I could see from my window. One was made with a team. The other four show the range.
01 / 05 · Voice AI · Python, Kotlin, Flask
Voice in, action out. Not a chatbot with a microphone — a system that turns "turn on the flashlight" into hardware state.
ARIA pairs a Python brain with a Kotlin Android bridge. A skill router scores incoming speech against regex and keyword patterns and only hands off to an LLM when nothing matches, so device control stays instant and offline-safe. It remembers your name, runs as an installable PWA, keeps listening with the screen off via a wake lock, and ships with a kill switch that halts voice, processing and the server at once.
02 / 05 · Marketplace · Flutter, Dart, Firebase
In most Cameroonian neighbourhoods, waste doesn't get collected because nobody owns the last mile. Re-kollect gives that last mile to independent collectors.
Two roles, one app. A generator posts a pickup with waste type, a map pin and a landmark description; a collector sees live requests, claims one, and calls the customer straight from the dashboard. Built from a PRD to a working MVP: Firebase phone auth, a Firestore request lifecycle, OpenStreetMap with Nominatim geocoding, FCM topic fan-out, and a glassmorphic eco-green interface that stays legible in daylight.
03 / 05 · Team delivery · Next.js 16, React 19, Tailwind 4
Solo work proves you can build. Team work proves you can be built around.
Selected for Orange's Ignite Circle 2026 programme, I worked as one contributor on a shared Next.js 16 / React 19 client — a green-theme design system with reusable components and a Zustand state model. The discipline that mattered wasn't writing the most code; it was following a common AGENTS.md, keeping to a branching convention, reviewing peers' work, and leaving the codebase easier to enter than I found it.
04 / 05 · Mobile · React Native, Expo, Reanimated
Health apps die of boredom. The fix is feedback you can feel in the first three seconds.
Five curated workout plans, a guided live session with countdowns and rest periods, and animated activity rings built with Reanimated and SVG. Data moves both ways: steps, energy and exercise minutes come in from Apple HealthKit and Google Fit, completed workouts go back out. When the native module isn't there, simulated data keeps every screen usable instead of showing an error.
05 / 05 · Computer vision · Python, MediaPipe, OpenCV
Draw in the air with your finger. No tablet, no stylus, no calibration ritual.
Air Canvas reads hand landmarks from a webcam and maps finger counts onto a five-state mode machine: one finger draws, two hover, three erase, and a four-finger pinch opens a six-colour palette. It's the smallest project here and the one that taught me the most — when your input is a human hand moving in real time, a dropped frame is a broken line. I tuned the tracking loop until it felt like ink.
Also shipped
Architected and deployed with a 3-person team for the Prometheus AI Hackathon, where it placed 4th. Supabase and the DeepSeek API are wired together to process dynamic user requests under tight time constraints.
A web application that helps users create strong passwords and test the strength of their current ones. Each weakness is explained in plain language, with a stronger passphrase suggested in its place.

Looking for
A product team where I own a slice end to end — full-time or contract
Languages
English & French (fluent, bilingual)
Phone
Response time
Usually within a day — I keep a short inbox
I want to work on systems where software meets the physical world — devices, sensors, logistics, health. The through-line in everything above is the same: a model or a screen is only half the product, and the other half is the boring plumbing that makes it work on a cheap phone with a bad connection.
Over the next few years I'm aiming to deepen distributed systems and on-device ML, and to keep shipping products that people in places like Buea can actually use. I'd like to do that inside a team that reviews code properly and treats documentation as part of the deliverable — the way I try to work already.
I'm not precious about stack. I've shipped in Python, TypeScript, Dart and Kotlin, and I pick up whatever the problem needs.
