I'm a backend software engineer with hands-on experience designing and building production-ready APIs, authentication systems, and financial infrastructure. I specialize in the Python ecosystem and have delivered real-world platforms handling payments, user management, and data integrity at scale.

• Trained at ALX Africa — one of Africa's most rigorous software engineering programs
• Built and shipped fintech backends processing M-Pesa payments and QR-based transactions
• Experienced in multi-role system design — connecting end users, merchants, and administrators through unified APIs
• Comfortable taking a backend from architecture → implementation → deployment

• Mobile payment integration for contributions and repayments
• Token-based authentication with permission scoping

• Qualification-based vehicle access control
• Admin panel for vehicle, driver, and lease management
• Payment processing and lease lifecycle tracking
• Structured API with full endpoint documentation
