jontAWorld - Josiah, digital product developer

What I do

I design and build digital products from the first working flow to a production-ready release. My work covers the interface, backend, third-party integrations, deployment, and the details that keep real users from getting stuck.

Connect payment providers, wallets, identity systems, callbacks, webhooks, and external APIs safely.
Backend and data

Design APIs, authentication, database models, permissions, validation, and operational admin tools.		 Launch and reliability

Prepare applications for deployment, mobile use, failure recovery, monitoring, and continued iteration.

Working stack

  • Frontend: TypeScript, JavaScript, React, Next.js, HTML, CSS
  • Backend: Node.js, Express, PostgreSQL, Supabase
  • Integrations: World ID, MiniKit, M-Pesa Daraja, Pi SDK, REST APIs
  • Delivery: Git, GitHub, Vercel, testing, deployment, technical documentation

Available for
