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.
Engineered an automated pipeline for fine-tuning large language models on custom datasets. Implemented LoRA/QLoRA techniques for efficient training, with automated evaluation metrics and A/B testing framework. Reduced training costs by 60% while improving model performance on domain-specific tasks. Handles datasets up to 50GB with distributed training across multiple GPUs.

Real feedback from real projects. No fluff, just results that matter.
"Brandon built us a custom customer management system that's been a game changer. Appointment scheduling is automated, and our customer database is finally organized. Worth every penny and he explained everything in plain English."
"The booking website Brandon created has completely transformed how we handle appointments. Clients love the online booking, and we've seen a 35% increase in bookings since launch. Professional work at a fair price."
"Working with Brandon on our AI chatbot integration was excellent. The chatbot handles initial client inquiries 24/7, and the fine-tuned responses are surprisingly accurate for legal questions. Great communication throughout the project."
"Brandon developed a React-based client portal that our advisors use daily. Clean interface, reliable performance, and he was patient with our feedback. The dashboard makes tracking portfolios much more efficient."
"The custom fine-tuned model Brandon built for routing optimization has saved us hours of manual work. It learns from our delivery patterns and suggests better routes. Solid technical skills and delivered on time."
"Brandon created a patient management system that integrates perfectly with our workflow. The React frontend is intuitive for our staff, and the backend handles all our records securely. Highly recommend for healthcare projects."
