Engagements & pricing
Packaged offerings, priced up front
Fixed-scope engagements with clear deliverables - from a one-time architecture audit to a production-ready MVP. Hosting plans are listed in the Hosting section below.
Fixed-Scope Engagements
06Architecture Audit
Get a clear picture of what is slowing your team down - and a practical 90-day plan to fix it. We review your code and infrastructure, prioritize the biggest risks and opportunities, then walk you through the findings live.
$1,500one-time
A focused starting point for teams that need clarity before investing in larger changes.
Production Fix Sprint
For an urgent technical problem that is blocking releases, hurting performance, or creating operational risk. We diagnose the issue, implement the fix, and leave your team with clear documentation for operating it.
$3,500–5,000one-time
Typically completed in 5–10 business days once access and scope are confirmed.
Legacy Application Modernization
Make an established application easier to maintain, safer to change, and less expensive to run. You’ll get a containerized development setup, dependency assessment, and a realistic modernization plan.
$3,000–4,500one-time
A strong fit for established PHP, Rails, or Node applications that need a safer path forward.
Discovery & Prototype
Turn a rough idea into a working prototype and a concrete build plan. We map the requirements, design the architecture, build a clickable prototype, and scope the real thing.
$2,500–5,000one-time
The usual starting point for a new web or desktop product. Prototype work applies to the build if you continue with us.
Web App MVP
Design, build, and ship a production-ready web application: backend, database, auth, payments if needed, deployment, and a handoff your team can operate.
$6,000–12,000one-time
Fixed scope for a defined MVP. Once it’s live we can continue on a support retainer.
Desktop App MVP
Native desktop applications for Windows, macOS, and Linux - internal tools, utilities, or shipped products - built with the right tooling for the job and packaged for distribution.
$8,000–15,000one-time
Cross-platform where it makes sense; single-platform when that’s the honest answer.
Retainers & Ongoing Support
03Ongoing help at a predictable monthly rate. Retainer hours are billed against our standard $225/hour senior rate - you just get priority access and a standing slot.

$1,125/month
Support Retainer

$2,250/month
Support Retainer
