About Dave

Bio

I have been working as an infrastructure engineer for 17+ years, with deep expertise in JavaScript, React, and AI/ML systems. I hold an Associates degree in Programming from Springfield Technical Community College. My hands-on experience includes building React applications at BuySellAds supporting 12,000+ advertisers, developing cross-platform web applications using modern JavaScript frameworks, and creating AI training pipelines with PyTorch.

I have been working as an infrastructure engineer for 17+ years, with deep expertise in JavaScript, React, and AI/ML systems. I hold an Associates degree in Programming from Springfield Technical Community College. My hands-on experience includes building React applications at BuySellAds supporting 12,000+ advertisers, developing cross-platform web applications using modern JavaScript frameworks, and creating AI training pipelines with PyTorch. As a core contributor to the kohya-ss framework (6.2k GitHub stars), I've implemented machine learning optimization techniques that are now industry standards, while also building browser-based AI tools serving 2,700+ monthly users with responsive React interfaces.
My tutoring approach focuses on practical, project-based learning that connects theory with real-world applications. While I haven't been a formal classroom teacher, I have extensive experience mentoring junior developers in JavaScript and React development across multiple companies. I've also created educational tools and maintained open source projects that serve as learning resources for the programming community. I break down complex programming concepts and machine learning algorithms into manageable steps, using concrete examples from systems I've built that handle millions of users and process AI models in production.
I'm particularly effective with students interested in JavaScript programming, React development, and machine learning applications. My unique advantage is demonstrating how these technologies work together in real systems - teaching React while showing how it integrates with AI backends, or explaining machine learning concepts through JavaScript implementations I've deployed. Students learn not just syntax and frameworks, but how to think like developers who build intelligent, scalable applications that solve actual problems in the modern tech landscape.

Approved Subjects

Linux

Linux

I have 17+ years of Linux experience, using it as my core operating system, with 8+ years specifically focused on Linux system administration managing distributed production server clusters. My expertise spans multiple distributions including Ubuntu, Arch, Debian, Fedora, and Gentoo, with most extensive experience in Ubuntu for both desktop and server environments. I've architected and maintained Linux-based infrastructure serving millions of users, including distributed systems at Virb supporting 450K+ users and high-throughput platforms at BuySellAds handling 6 billion monthly impressions. My Linux skills include system administration, performance optimization, distributed system deployment, and troubleshooting complex production issues across multiple server environments.
Machine Learning/ AI

Machine Learning/ AI

I have 2+ years of hands-on experience building AI models, training pipelines, and inference systems using PyTorch and diffusion models. As a core contributor to the kohya-ss AI training framework with 6.2k GitHub stars, my code is used by hundreds of thousands of developers worldwide and powers commercial platforms generating $300k+ annual training revenue. I've developed innovative optimization techniques like LoRA+ and LoRA-GGPO that achieve 2x training speed improvements with 30-70% VRAM reduction, which have become industry standards adopted across the AI community. My expertise spans neural network training pipelines, model efficiency optimization, preference optimization techniques (DPO, MaPO, DDO, BPO), and implementing cutting-edge research papers into production systems within weeks of publication.
React

React

I have 5+ years of hands-on React development experience building production applications across multiple companies and projects. At BuySellAds, I built CI/CD pipeline infrastructure supporting React component validation and automated deployment for advertising platforms serving 6 billion monthly impressions. I've architected cross-platform web applications at Ecogarden Design using React with high-performance rendering systems and complex offline functionality using ServiceWorker and IndexedDB. Most recently, I've developed browser-based AI tools with responsive React interfaces serving 2,700+ monthly users, focusing on optimized component architecture, state management, and creating intuitive user experiences for complex technical applications.
