One Engineer. AI Workforce.

The quality of a boutique agency at the speed of an army.

Software Development, Reimagined

Most dev shops have a problem: they hire junior developers, layer on project managers, and charge agency rates for inconsistent work. Or they're a solo freelancer who can only take one project at a time.

Sumtek Solutions is neither. It's a senior engineer backed by an AI-powered development workforce that builds software in parallel. Multiple agents working simultaneously — writing code, reviewing each other's work, retrying on failure — while a human engineer architects the solution and ensures quality.

The result: your project gets the attention of a senior engineer and the throughput of an entire team. Working prototypes in days, not weeks. Production code that's tested, documented, and deployed.

How We Build

Every project follows the same proven pipeline. You see results before you commit.

1

You Describe It

Tell us what you need in plain English. Our AI analyzes your description and recommends exactly which features apply. You adjust, pick colors, and see 3 custom mockups — free, before you spend a dollar.

2

AI Agents Build It

Once you approve, our AI workforce decomposes the project into tasks, assigns them to parallel agents, and starts building. Each agent writes code in its own workspace, gets reviewed by another agent, and retries until it passes. A senior engineer oversees every line.

3

You Preview It

Your project deploys to a private staging URL. You can see it, use it, and give feedback. Changes get implemented the same way — fast, parallel, reviewed.

4

We Ship It

When you approve, we deploy to production. You own 100% of the source code, full Git history, architecture docs, and deployment configuration. No lock-in. It's yours.

Why This Works

Traditional Agency
  • Junior devs doing the work
  • Project managers adding overhead
  • Weeks to see first results
  • $150-300/hr, inconsistent quality
  • Communication through intermediaries
Solo Freelancer
  • One person, one project at a time
  • Limited capacity and availability
  • No infrastructure or CI/CD
  • Quality depends entirely on one person
  • Slow turnaround on changes
Sumtek Solutions
  • Senior engineer architects every project
  • AI workforce builds in parallel
  • Working prototype in days
  • Flat-rate pricing, no surprises
  • Direct access to the engineer building it
Founder & Lead Engineer

Josh Preston

Full-stack engineer who builds production software from infrastructure to interface. The human behind the swarm.

I've shipped fintech platforms, e-commerce systems, SaaS applications with OAuth and passkeys, and cryptocurrency payment integrations — all running in production. My stack spans Go, TypeScript, Dart, SvelteKit, and Terraform. Every project gets CI/CD, automated testing, security headers, and production-grade infrastructure from day one.

When you work with Sumtek, you work directly with me. I design the architecture, review every line of code the AI agents produce, and make the final call on what ships. The AI is the workforce. I'm the quality gate.

Based in Idaho. Available for select remote engagements.

What Every Client Gets

Source Code Ownership

You own 100% of the code, full Git history, and all documentation. No vendor lock-in. Transfer to any team at any time.

Production Infrastructure

CI/CD pipeline, automated testing, staging environment, security headers, and monitoring — included, not upsold.

Flat-Rate Pricing

You know the price before work begins. Fixed scope, fixed cost. Change requests are quoted transparently before they start.

Direct Communication

You talk to the engineer building your project. Not a sales rep, not a PM. Questions answered in hours, not days.

Security by Default

Every project ships with encrypted connections, input validation, authenticated APIs, and OWASP-aware development. Security is a requirement, not an add-on.

14-Day Support

Bug fixes for 14 days after delivery at no extra cost. Or continue with a retainer for ongoing development and dedicated AI agent support.
