B2B SaaS
SuitFlow
Workflow software for formalwear shops managing weddings, party members, measurements, tailoring, special orders, follow-ups, messaging, staff access, and billing.
Secure software and AI systems, built for real work.
I am Caleb Stammen, a software developer and AI lead at Garmann Miller, founder of Stammen Technology, and builder of products like SuitFlow and Atlas. My work spans applied AI, full-stack software, cybersecurity, infrastructure, and business automation.

Featured projects
Product work with enough detail for technical evaluators.
The strongest work here is not a list of languages. It is the pattern: find a real workflow, design around the people who use it, build the system, and keep security and operations in view.
Atlas screenshots pending
Reserved for real iOS screenshots Caleb will provide.
Local-first iOS
Atlas
A private travel map and journal built with SwiftUI and SwiftData for tracking real travel history without requiring an account or cloud sync.
Founder work
Stammen Technology
Custom software, AI, web development, ecommerce, mobile applications, automation, and SaaS foundations for businesses outgrowing disconnected tools.
Focus areas
Where I can contribute quickly.
I work best where software, AI, security, and infrastructure overlap, especially when the problem is tied to real operational pressure.
Applied AI and LLM systems
Building AI workflows that fit real business processes, including internal knowledge, meeting minutes, onboarding, learning, and project information workflows.
LLMs, RAG thinking, evaluation, rollout
Secure software development
Combining software engineering with cybersecurity training, secure design, infrastructure experience, and practical risk awareness.
Secure design, auth, permissions, recovery
Full-stack product engineering
Designing and building products from vague operational pain into usable workflows, interfaces, APIs, and production systems.
React, JavaScript, .NET, C#, Python, SQL
Cloud, Microsoft 365, and infrastructure
Experience with Azure, Microsoft 365, SharePoint, Teams SDK, Microsoft Graph, endpoints, Windows Server, networking, backups, and automation.
Azure, Graph, SharePoint, Power Platform
Cybersecurity and incident response
Graduate work and hands-on experience across secure network design, security operations, penetration testing, NIST-aligned security initiatives, and disaster recovery planning.
PenTest+, CySA+, Security+, NIST
Business automation and internal tools
Replacing spreadsheets, repeated manual steps, scattered information, and brittle handoffs with systems that people can actually use.
APIs, workflow design, data routing
About
I started in technology the unglamorous way.
I saved for a laptop, learned to code, fixed systems, supported users, and eventually owned the infrastructure those systems depended on. That path still shapes how I build software. I care whether a system works in the real world, whether people can trust it, whether it fails safely, and whether it removes friction from someone's day.
Today, I lead AI initiatives and build software at Garmann Miller, run Stammen Technology as a solo-owned software studio, and build products such as SuitFlow and Atlas.
Experience
Broad because the work has required it.
Software, AI, infrastructure, security, and business ownership are not separate stories here. They are the same path seen from different angles.

Where I fit
I am interested in work where software, AI, security, and infrastructure meet.
Applied AI engineering, secure product engineering, internal tools, infrastructure-aware software, developer platforms, and systems that need careful thinking as much as code.
