About | Sumtek Solutions — AI Development & Integration

From IT Consulting to AI Engineering

Sumtek Solutions started as a general IT consulting practice — the kind of work where you troubleshoot servers, configure networks, and help businesses keep their technology running. It was good work, but the landscape shifted.

AI changed everything. Not the hype cycle version of AI, but the practical reality: language models that can process documents, agents that can execute workflows, and protocols like MCP that let AI tools interact with real business systems. This is the work that matters now.

Today, Sumtek Solutions is focused entirely on AI development and integration. We build the servers, APIs, agents, and applications that let businesses actually use AI — not just talk about it. Every project ships to production with documentation, tests, and infrastructure included.

The name "Sumtek" comes from "Sum" (total) + "tek" (tech). The idea was always about bringing the full picture together. That hasn't changed — just the tools we use to do it.

Founder & Lead Engineer

Josh Preston

Full-stack engineer with deep expertise across the entire development stack — from infrastructure and DevOps to frontend interfaces and everything in between.

I've built multi-platform messaging systems, cross-platform fintech applications, photo marketplaces with microservices architecture, cryptocurrency trading tools, and cloud infrastructure with Terraform. I write production code in Go, TypeScript, Python, Dart, Swift, and Kotlin.

When you work with Sumtek, you work directly with me. No project managers relaying messages, no junior developers learning on your dime. You get a senior engineer who understands both the technical implementation and the business context.

Based in Idaho. Available for remote engagements nationwide.

How We Work

Ship to Production

Every project is deployed, documented, and production-ready. We don't hand off prototypes and call it done. You get working software that runs in the real world.

You Own Everything

Full source code ownership, complete Git history, and thorough documentation. No vendor lock-in, no proprietary platforms, no ongoing dependencies on us.

Fixed Prices, Defined Scope

We quote fixed prices for defined work. You know exactly what you're paying before we start. Scope changes are handled through a transparent change order process.

Direct Communication

You communicate directly with the engineer building your project. No intermediaries, no telephone game. Questions get answered fast and accurately.

Security First

Every application is built with security as a core requirement, not an afterthought. Encrypted data, authenticated APIs, input validation, and OWASP-aware development practices.

Practical, Not Flashy

We build solutions that work and deliver ROI. No unnecessary complexity, no over-engineering, no technology for technology's sake. The right tool for the right problem.
