Hi, I'm Tanner 👋

Full-Stack Software & AI Engineer building AI-native products, developer tools, and the next generation of software.

I'm passionate about creating software where AI, product design, and distributed systems intersect. I enjoy turning complex infrastructure into intuitive, high-quality experiences that help engineers build better software.

Currently, I'm building Visa AI Studio at Visa—an AI-native platform that enables engineers and data scientists to build, deploy, manage, and operate intelligent systems at scale.

What I Build

My work spans the full product and engineering stack:

• AI-native web applications
• Agentic and multi-agent systems
• Generative user interfaces
• Developer tools and internal platforms
• Real-time and distributed applications
• Federated APIs and backend services
• High-craft, accessible product experiences
• Infrastructure abstractions that reduce operational complexity

I particularly enjoy building products that make sophisticated AI and infrastructure capabilities usable without requiring users to understand every underlying system.

Current Interests

I'm currently exploring and writing about:

• Agentic software engineering
• AI developer experience
• Context engineering and optimization
• Generative UI
• Human–AI interaction
• Multi-agent architectures
• Distributed systems
• Database engineering
• Developer tools
• Modern product engineering
• AI-assisted software development

Engineering Philosophy

I believe the best engineering work combines:

• Strong technical foundations
• Thoughtful product design
• Clear abstractions
• Reliable systems
• Deep empathy for users
• Intentional use of AI as an engineering tool

AI is changing how software is designed, built, and operated, but the fundamentals still matter: understanding the problem, defining clear boundaries, making sound architectural decisions, validating assumptions, and shipping software that works.

Currently Building and Learning

• AI-native developer tools
• Agent infrastructure and workflows
• Context-efficient systems for coding agents
• Native applications for managing parallel AI work
• Open-source tools for modern software development
• Deeper foundations in distributed systems and database engineering

Writing and Teaching

I enjoy writing and teaching about:

• AI engineering
• Software architecture
• Distributed systems
• Web engineering
• Developer experience
• Agentic software development

My goal is to make complex engineering concepts approachable without sacrificing the technical depth that makes them useful.
