I'm Brandon van Vuuren, a full-stack developer and emerging AI engineer who builds systems that actually ship and scale. I work across React, Next.js, Node.js, Python, C#, C++, and Astro, with practical experience turning AI models into real, usable product features.
I build end-to-end solutions across modern frontends, scalable backend APIs, and cloud infrastructure. Whether architecting microservices or deploying ML models, I focus on maintainable code, system reliability, and real business value.
Production applications engineered for scale, performance, and exceptional user experience
Developed a high-performance streaming analytics dashboard processing 10k+ events per second. Features real-time data visualization, custom pipeline configurations, and multi-source data ingestion. Optimized for low-latency monitoring with automated alerting and anomaly detection.
Built a comprehensive coding challenge platform with AI-powered code review, automated testing, and real-time feedback. Features include difficulty-adaptive challenges, performance analytics, skill tracking with badges, and detailed coding metrics. Used by companies for technical interviews and by developers for skill improvement.
Developed an AI-powered invoice management system that automatically extracts, categorizes, and processes invoices from multiple formats. Features OCR, smart data validation, duplicate detection, and seamless ERP integration. Reduced manual processing time by 80% and improved accuracy to 99.5%.
Custom AI solutions that work—automation, fine-tuned models, and intelligent bots that deliver real business value
Custom language models trained on your data. Specialized GPT models that understand your domain, your customers, and your business logic.
Intelligent automation that eliminates repetitive tasks. Workflows that adapt, learn, and improve over time without human intervention.
AI assistants that handle customer support, sales, and internal operations. Available 24/7, scalable to millions of conversations.

Real feedback from real projects. No fluff, just results that matter.
"We needed a way to track appointments and customer info without the chaos of spreadsheets. Brandon built us something that actually works for our shop. Staff picked it up quickly and it's been reliable since day one."
"The online booking system Brandon put together has cut down on phone calls significantly. A few clients had minor issues at first, but he fixed those fast. Overall solid work and fair pricing."
"Had Brandon build a chatbot to handle basic client inquiries. It's not perfect for complex questions, but it saves our reception staff time on the routine stuff. Good value for what we paid."
