Let’s talk

Software engineer and video editor, open to new work

I builddelivery apps, multiplayer games, AI assistants, offline-first tools, bank software, school systemsthat hold up on slow networks.

Software engineer from Cameroon, based in Liberia. The frontend is my home base. Lately most of my hours go into the other half: Supabase schemas, NestJS services and realtime game servers.

Three projects I’d walk you through first, then everything else I’ve built over the last two years.

HUNTED logo

First-person horror game, 2026

Playable now

HUNTED

A browser horror game in a haunted mansion. You play an agent searching for a missing colleague while a spider, snake and human creature hunts you by sound and by the beam of your flashlight. Ten documents tell the story of the family who lived there.

  • three.js
  • WebGL
  • Web Audio API
  • JavaScript
Play now
+How it’s built
  • A two-storey house built from text floor plans, with doors, stairs, collision and a navigation grid the creature uses to hunt
  • The creature combines a realistic human model with spider legs that step using inverse kinematics and a tail that follows her real path
  • Almost every sound is synthesised live and placed in 3D, so walls muffle what is behind them; footsteps use real recordings
Gamefy logo

Multiplayer web games, 2026

Complete

Gamefy

Three browser games for one to six players in the same room: two TV quiz formats and Yolo!, a card game in the spirit of UNO with a Classic mode and a brutal Inferno mode. Play alone against bots or share a room code with friends; every phone stays in step.

  • Angular
  • three.js
  • NestJS
  • Colyseus
  • TypeScript
  • Web Audio API
Play now
+How it’s built
  • Yolo! plays on a 3D stage for each mode, a funfair pier for Classic and a lava crater for Inferno, with every opponent's cards lying on the table in front of them
  • Authoritative game server with rooms, bots that fill empty seats and two-against-two team play; each device only ever sees its own hand
  • A voice calls every action card, and the crowd claps and gasps, modelled clap by clap and breath by breath in Web Audio
Karrio logo

Delivery platform, 2026

Heading to launch

Karrio

A multi-vendor delivery app for Monrovia covering restaurants and supermarkets. Four apps share one Supabase backend: customer and driver apps in Expo, plus web apps for vendors and admins. It started as my thesis and is now being prepared for real customers.

  • React Native
  • Expo
  • Supabase
  • PostgreSQL
  • PWA
+How it’s built
  • Customer, vendor, driver and admin apps with their own roles and permissions on one database
  • Order and vendor flows designed as state machines before any screen was drawn
  • Payments built against test mode first, with mobile money support planned for launch
Audify logo

Music streaming app, 2025

Audify

A streaming app that pairs Spotify metadata with YouTube playback so full songs stay available, then drops short AI DJ commentary into a playlist to make it feel like radio.

  • React Native
  • Expo
  • TypeScript
  • Zustand
  • Spotify API
  • OpenAI
+How it’s built
  • Track matching across sources, with a fallback when one provider has nothing
  • A mini player that keeps playing and keeps its place as you move around
  • “Because you listened to” rows that recommend without spending AI tokens

Day job

By day, I build software for a bank.

I work on internal software at a commercial bank in Monrovia. It is where I learned that quiet, reliable systems are the hardest ones to get right: nobody notices them until they stop working.

Client data, internal names and anything confidential stay at the bank. What is here is described in general terms on purpose.

  1. 1

    Back-office tools

    Screens staff use to prepare, check and track loan documents, replacing paper forms and scattered spreadsheets.

  2. 2

    Backend services and APIs

    The services behind those tools, including an API that lets customers subscribe to SMS alerts.

  3. 3

    Automation

    Scripts that take repetitive document and cheque-processing work off people’s desks.

  4. 4

    Training and support

    Written guides and hands-on sessions that help colleagues move onto new systems with confidence.

About me

I started with static HTML pages, moved through C++, C# and Python console programs, and found my footing when React made interfaces feel like systems instead of pages.

Most of what I build is shaped by where I live. Exchange rates that still load on a weak connection. A health assistant you can talk to instead of type to. A delivery app sized for Monrovia’s restaurants and supermarkets.

By day I build internal software at a bank. It has made me better at planning, writing things down and shipping things that must not break.

I also edit video. Pacing and restraint matter as much in a cut as they do in an interface.
