Senior Software Developer & Founder


years of professional software development. I've founded multiple tech companies, built SaaS products processing 500,000+ transactions monthly, and delivered enterprise solutions across mobile, desktop, web, and backend systems.

Current focus: AI/ML integration, cross-platform mobile development (Flutter, React Native), and scalable backend architectures. I build products that solve real problems - from biometric SDKs for wearable health tech to AI-powered training platforms and automated document recognition systems.

Full-stack capability: Native iOS (Swift, Objective-C) and Android (Kotlin, Java), cross-platform (Flutter, React Native), desktop (Electron, NW.js), backends (Laravel, Node.js, Go, Python), and cloud infrastructure (AWS, Firebase, Google Cloud).

Entrepreneurial track record: Founded DriverScan (license recognition SaaS), built and sold a point-of-sale company with installations across Southern Africa, and co-founded TopItUp (vending startup, exited 2013).

Technical depth: From low-level C/NDK and assembly to modern LLM integrations with OpenAI. Databases from legacy Firebird to DynamoDB. Blockchain smart contracts in Solidity. I understand systems from the ground up.
