Freelance full-stack developer & QA engineer in Accra, Ghana. I turn your idea into a website, web app or mobile app that works, and I test it before you launch. For business owners, founders and teams, in Ghana and worldwide.

How much does a website or app cost?+
It depends on what you need. After a short call I send a fixed quote for the agreed scope, so you know the price before any work starts.
How long will it take?+
A business website usually takes a few weeks. Web and mobile apps take longer depending on features. You get a timeline in the quote.
I'm not technical. Is that a problem?+
No. I explain things in plain language, and you only make the decisions that matter to your business.
Can I update the site myself afterwards?+
Yes. Where it makes sense I add a simple editor (like Sanity) so you can change text, photos and products without a developer.
What happens after launch?+
I test before going live, then stay available to fix issues and make changes. Ongoing support can be arranged if you want it.
// got a project? a bug? doubts?
WhatsApp is fastest. I usually reply within a day, whether it's a website for your shop or a role on your team.
