I'm a software engineer with 10+ years of experience designing, building, deploying, and maintaining production-grade software systems.

My work spans backend engineering, payment systems, enterprise applications, SaaS platforms, API integrations, data-intensive systems, and cloud infrastructure. I enjoy turning complex business requirements into reliable, scalable, and maintainable software.

I have worked extensively with Go, Java, Python, TypeScript/JavaScript, PostgreSQL, Redis, REST APIs, Docker, AWS/GCP, CI/CD, and Linux, with a strong focus on backend and distributed systems.

A significant part of my engineering experience has been building systems around payments, financial transactions, and revenue-authority integrations.

Experience includes:

• Mobile money integrations
• M-Pesa payment systems
• Payment gateways
• Payment reconciliation
• Transaction processing
• Agent disbursement systems
• Maker-checker workflows
• USSD applications
• KRA eTIMS integrations
• VSCU / OSCU integrations
• Electronic invoicing
• Fiscal invoice processing
• Invoice and credit-note integrations
• High-volume transaction processing

I enjoy working on systems where correctness, reliability, observability, and data integrity matter.

I've worked on and contributed to systems involving:

• ERP and POS platforms
• CRM systems
• Healthcare applications
• Insurance platforms
• Payment platforms
• Tax and fiscalization systems
• Inventory management
• Sales and invoicing
• Expense management
• Reporting and analytics
• SaaS platforms
• Multi-branch business systems
• API-driven integrations

My approach is to understand the underlying business process first, then design the technology around it.

I care about more than simply making software work.

My engineering priorities include:

Reliability
    ↓
Correctness
    ↓
Security
    ↓
Performance
    ↓
Maintainability
    ↓
Scalability

I particularly enjoy solving problems involving:

• High-volume data processing
• Slow database queries
• Distributed services
• External API failures
• Retry and idempotency strategies
• Caching
• Concurrency
• Background processing
• Fault tolerance
• Resource optimization
• Production debugging
• Deployment automation

Designed and maintained APIs and services supporting payment workflows, transaction processing, mobile money integrations, and financial operations.

Built and maintained integrations between business applications and electronic tax invoicing systems, including invoice transmission, fiscalization workflows, classifications, credit notes, and related APIs.

Developed business systems covering:

• Point of Sale
• Sales invoices
• Inventory
• Stock movements
• Purchases
• Credit notes
• Delivery notes
• Expenses
• Reporting
• Multi-branch operations
• Tax integration

Worked on healthcare workflows involving branches, caregivers, clients, schedules, service agreements, clock-in/out, signatures, payers, and service management.

Optimized backend and database workloads through query optimization, indexing, caching, asynchronous processing, and architectural improvements.

One example involved reducing a signing API operation from approximately 56ms to 14ms through backend and database improvements.
