Custom Web Application in Nairobi: what you get
When spreadsheets, WhatsApp groups and paper records start slowing a business down, a custom web application replaces them with one system your whole team can use from any device. Examples include booking platforms, client portals, inventory trackers, internal dashboards, marketplaces and subscription services.
We build web applications with modern tools such as Next.js, React, Laravel, Node.js and Supabase, and design the database, user roles and security properly from the start so the system can grow. We integrate Kenyan essentials including M-Pesa (Daraja API), SMS and email alerts, and WhatsApp notifications.
Projects are managed in clear stages with working demos along the way, so you see progress and can adjust before the budget is spent.
