Backend Software Engineer | Python Specialist | Data Analytics Practitioner

I’m a backend-focused software engineer with a strong specialization in the Python ecosystem, particularly Django-based backend systems. I design and build scalable backend application logic, architect production-ready systems, and use data analytics to solve real operational and business problems.

Alongside Python, I’m currently learning Go, focusing on performance-oriented backend services and deeper system-level design.

My approach to engineering is grounded in first-principles thinking — breaking problems down to what actually matters, eliminating unnecessary complexity, and building only what moves the system forward.

I believe in:

• Shipping early and often over over-engineering
• Building fast, then iterating based on real usage
• Testing assumptions in production, with proper monitoring and rollback strategies
• Simple systems that evolve, rather than perfect systems that never ship
• Engineering as a feedback loop, not a one-time design exercise

Python is my primary language and the foundation of most systems I build:

• Django – Core framework for business-critical backend systems
• REST APIs – Authentication, authorization, permissions, and domain-driven logic
• Backend Architecture – Modular apps, service layers, and reusable components
• Performance & Stability – Query optimization, caching, background tasks

I combine backend engineering with data analytics to improve systems and operations:

• SQL – Reporting, analytics, and performance tuning
• Python Data Stack – Pandas, NumPy
• BI Tools – Power BI, Tableau
• Jupyter – Exploratory analysis and prototyping

I’m leading the engineering of CBC AI, a platform focused on optimizing Kenyan school operations end-to-end.

We are building systems that cover:

• Academic management — curriculum, assessments, performance tracking
• Financial operations — fees, payments, reporting, and reconciliation
• Operational systems — including low-level Biometric and RFID-based solutions
• Backend services & APIs designed to scale across multiple institutions
