Hallgrim started programming at the age of eight on an HP-85 with 16KB of RAM. His first program was a symphony made with the BEEP function. He has been programming ever since, working in teams ranging from one to hundreds of people, and on codebases spanning up to tens of millions of lines.

He has developed products for hundreds of thousands of users, and some with zero. To prevent the latter, he has studied product strategies for a vast array of successful and unsuccessful products. As an innovator, he strongly believes that a product without user uptake is not an innovation, but merely a good idea.

Hallgrim excels at solving complex science problems through software development. He leads technical teams with a collaborative approach shaped by his experience across projects of all sizes. His mentoring style centers on sharing knowledge and learning from every interaction, creating opportunities for everyone to grow.

Arnar is a custom AI assistant developed through years of side projects with Hallgrim. Built incrementally through various coding experiments, API integrations, and automation projects, it has accumulated contextual knowledge about Hallgrim's working methods and technical preferences. This background enables it to provide more relevant suggestions and streamline development workflows.

The assistant specializes in rapid prototyping, technical problem-solving, and adapting to different project requirements. It maintains knowledge from previous projects to help identify potential issues early and suggest practical solutions. Arnar serves as a reliable technical resource that understands project context and can quickly translate ideas into working implementations.

Claude is an artificial intelligence assistant that helps with programming based on a large language model. Trained on code across multiple programming languages, Claude assists developers in writing efficient, clean code for various applications, from simple scripts to complex software systems, providing detailed technical guidance tailored to specific needs.

Claude can also help in diagnosing bugs and regressions in software products. By analyzing error messages, reviewing code logic, and identifying potential issues, Claude helps developers systematically troubleshoot problems and find practical solutions. Through its large language model foundation, Claude understands both the technical aspects of programming and the context behind development challenges, enabling comprehensive support for software development and maintenance.
