Full-Stack Engineer | Systems Architect | Cybersecurity Specialist | Freelancer

👨‍💻 Currently building:

• Full-Stack Systems (Django, FastAPI, TypeScript, Next.js, Microservices)
• Fintech & Telecom Integrations (Airtel Money, PayChangu, SMS Gateways, Mobile Money, Banking APIs)
• Offensive & Defensive Cybersecurity (Penetration Testing, Zero-Trust Architecture)
• Cross-Platform Mobile Development (Flutter, Advanced State Management)
• AI/ML Systems & Algorithm Optimization (Deep Learning, Computer Vision, Reinforcement Learning)

I'm a full-stack engineer who builds secure, production-grade software — from backend architecture and mobile apps to the payment and telecom integrations that make real businesses run. I work across Python, Django, FastAPI, TypeScript, Flutter, Docker, Kubernetes, and PostgreSQL, with a strong focus on cybersecurity practices throughout the development lifecycle.

A core part of my work is integrating systems that businesses in Malawi and beyond actually depend on: Airtel Money, PayChangu, SMS gateways, and other mobile money and banking APIs. I've built payment flows and notification systems that connect applications directly to telecoms and financial institutions — the kind of integration work that turns a prototype into something clients can trust with real transactions.
