I'm Joab Irungu Ndego, a full-stack developer focused on web applications, backend systems, payment integrations and digital tools for real business workflows. I work across frontend experiences, APIs, databases and deployment.
I build and maintain projects spanning digital marketplaces, airtime workflows, property websites, personal finance tools and e-commerce. My work combines product thinking with hands-on implementation: user interfaces, REST APIs, authentication, data models, payment workflows and deployment.
My strongest areas are JavaScript/TypeScript backend development, database-backed applications and integrations that connect software to everyday business processes.
A focused selection of repositories and websites I have worked on. Open the repository to review the code; live links are included only where a known public URL is available.
A digital marketplace project focused on seller workflows, orders, payment integration and secure digital-product delivery. Frontend and backend are maintained in separate repositories; feature readiness depends on the current deployment and configuration.
A customer-facing airtime portal designed for Safaricom and Airtel purchases at face value, with separate bulk-discount logic where applicable. This is distinct from the separate Bingwa Automation concept.
Node.js and Express backend for Daraja-related payment and airtime workflows, including callback handling and PostgreSQL-backed components. The repository is the best place to inspect current routes and integration status.
An Expo and React Native app project for airtime and USSD-related workflows. See the repository for the current implementation, dependencies and supported device capabilities.
Property-management and real-estate website work focused on presenting services, property information and enquiry pathways for a Kenyan property brand.
Responsive property-agency website rebuild with agency information, property enquiry journeys and branded service pages. Visit the live website or open the repository to review the project.
A Kenya-focused personal finance and budgeting application project. Its backend repository includes an Express and PostgreSQL setup with authentication and AI-provider integrations; review the repositories for current implementation details.
A mobile-first rental discovery project for people exploring houses, apartments and bedsitters in Kenya. Visit the site to see the current experience; listing accuracy depends on the live inventory.
Client e-commerce and product-catalogue work for a Kenyan retailer. The site presents products and shopping journeys; this portfolio entry identifies it as client work rather than claiming ownership of the business.
My digital-solutions brand and portfolio for web development, integrations and digital services. This is the public site for the brand and a starting point for exploring its work.
Portfolio descriptions are intentionally scoped to project goals and repository context; they do not imply that every planned integration or feature is currently enabled in production.
