AI Systems Engineering
Build the AI product, search system, or integration your team can run in production.

AI systems that work beyond the demo
A production system must survive real data, permissions, exceptions, changing models, and real users. Arsum connects architecture, data, system behavior, acceptance criteria, human review, monitoring, rollback, and ownership.
Three central capabilities
AI products and applications
Production web and mobile products with the application, back-end, AI, review, testing, and deployment layers treated as one system.
Intelligent search and data systems
Data ingestion, pipelines, search, retrieval, multi-source research tools, dashboards, and evidence-linked interfaces.
AI integration, evaluation, and production readiness
AI and agent integration, evaluation sets, quality gates, human review, tracing, monitoring, cost controls, rollback, and post-launch support.

What clients say after shipping with Arsum
Direct feedback from the people behind Attuned Health, ProjectMe, and Ejendomsindex, connected to the work it supports.
“Johnny is incredibly talented, resourceful, and thoughtful in everything he does. He consistently thinks outside the box, finds creative solutions, and covers details others might miss. He’s thorough without slowing things down and has a great ability to anticipate problems before they become problems. Just as importantly, he’s considerate, collaborative, and genuinely easy to work with. He listens, challenges ideas when needed, and always feels like a true partner in building something better. I have a tremendous amount of trust in both his work and his judgment, and he’s been an incredibly valuable part of what we're building.”
“Johnny is one of the few developers that is able to meet or exceed my expectations. His delivery is always on time and he has the ability to take extra steps on items that are beneficial but not necessary. Highly recommend.”
“It is amazing how much that can be built so fast :-)”
