Web applications
Frontends built in React and Next.js, wired to real backend logic — authentication, business rules, and data that has to stay correct, not just display.
- Next.js & React
- APIs & auth
- PostgreSQL / Supabase / Firebase
- Performance & SEO

What I build, the stack behind it, how engagements run — solo or embedded in your team — and roughly what they cost, so you can tell in a minute whether this is a fit.
What I build
( Capabilities )
AI agents & automation
Assistants and workflows that do something, not just answer questions — connected to messaging channels and the tools they need to act.
- Tool-enabled AI agents
- WhatsApp / messaging integration
- Workflow automation
- MCP servers
Games & real-time systems
Socket-based multiplayer infrastructure and matchmaking across game modes — the same systems-thinking applied to latency and concurrent state instead of request/response.
- Unity & Unreal Engine
- Three.js / WebGL
- Cannon.js & Ammo.js physics
- Socket-based multiplayer
Systems & integrations
The connective tissue between services: payments, external APIs and deployment that have to behave under real conditions, not just the happy path.
- Mobile money & payment APIs
- Third-party API integration
- Docker & deployment
- Data pipelines
Mobile & product builds
Taking a working idea to a usable product end to end — from the data model up through the interface someone actually uses.
- React Native / Capacitor
- Swift (Xcode) & Android Studio
- Ionic & Cordova
- MVP scoping & iteration
( Also building with )
Used when a project or an existing codebase specifically calls for it — not the default, so it sits here rather than padding out the categories above.
How I work
( Engagement )
Solo or embeddedRuns a build end to end as the sole engineer, or joins an existing team for a sprint, a feature, or ongoing capacity.
Async-friendlyComfortable working remote and async across time zones; calls when they're useful, not by default.
Focused capacityKeeps active engagements limited so attention doesn't thin out across clients, solo or embedded.
Direct lineYou talk to the person doing the work, start to finish — not a layer of account management.
What it costs
( Pricing )
Single build
A focused feature, landing page, internal tool, bug-fix sprint or one integration.
$350 – $1,200fixed price
- Scoped in a short call first
- One deliverable, clear definition of done
- 1–2 weeks typical turnaround
- 50% upfront, 50% on delivery
Most common
Full product
A complete web, mobile or game-backed product from scratch — auth, data, admin, and the integrations it needs.
$1,500 – $8,000+scope-dependent
- Milestone-based delivery
- Discovery before pricing is finalized
- Weekly progress check-ins
- 40% / 30% / 30% payment split
Ongoing partner
Continuous development, maintenance, or iteration after launch — an engineer on call without hiring one.
$800 – $3,000per month
- Part-time to dedicated availability
- Monthly billing, cancel with 30 days' notice
- Covers bug fixes, features & upkeep
- Priority response over one-off work
Ranges are a starting point — actual cost depends on scope, and every quote follows a short discovery call rather than a form. Rates can flex for students, early-stage founders and registered nonprofits — just say so.
These are set by scope and market value, not by location — the same build costs the same whether the brief comes from Douala, Lagos or San Francisco.
Joining an existing team instead of running a standalone build? Day-rate and sprint-based contracting is available too — mention it on the call.
Is this a fit?
( Self-check )
Good fit
- You need one person who can own a build end to end, not just a slice of it.
- You need a senior engineer to embed with your existing team for a sprint or a stretch of ongoing capacity.
- You're building something WhatsApp-first, mobile-first, real-time, or aimed at African markets.
- You have a clear problem but flexible opinions on exact implementation.
Probably not yet
- You need to hire and manage an entire team at once — I join or lead a build, not staff one.
- You need 24/7 on-call coverage — that's a different kind of arrangement.
- The ask is pure visual/graphic design with no software behind it.
- The opening offer is "that's a lot for your region" — the rate doesn't move based on where I'm sitting.
Common questions
( FAQ )
What's the smallest project you'll take on?
Roughly $350 worth of work. Anything smaller is usually better handled as a quick fixed-price fix rather than a full engagement — happy to say so upfront if that's the case.
How is a project actually priced?
Fixed price for clearly scoped work, milestones for larger builds, a monthly retainer for ongoing work. Every quote follows a short call — the ranges above are a starting point, not a menu.
Do you only build with Next.js and React, or can you join an existing team?
Next.js, React and Node are the default for new web work, but the broader stack above gets used when a project or an existing codebase calls for it — PHP/Laravel, Java/Spring Boot, C#, Unity/Unreal included. Joining an existing team for a sprint, a feature, or ongoing capacity is also on the table, not just solo end-to-end builds — day-rate or sprint terms available on request.
Do you work with clients outside Cameroon?
Yes — most engagements are remote and async, in English, across time zones. Payment can be arranged in USD or locally depending on where you're based.
Why not price lower, given where you're based?
Cost of living where the work happens doesn't change what a feature costs to build well, or what it's worth to the business using it. Rates here track the same market as freelance engineers anywhere else doing comparable work — they're not a regional discount.
Is there support after launch?
Yes, either folded into the ongoing-partner tier or as a smaller paid maintenance arrangement — whichever fits how much the product keeps changing.
How soon can you start?
Usually within one to two weeks, depending on what's already in progress. Ask and I'll give you a real answer, not a placeholder one.
