Custom Web Apps
Focused applications designed around a real workflow, audience, or operational need.
OptionStack Studio / Built by Jerry Welch
Useful software for real‑world problems.
I build focused web apps, internal tools, automations, and integrations for businesses, nonprofits, events, and community organizations.
Senior engineering experience. Small-team practicality. No agency parade required.
The situation
When spreadsheets, forms, and manual handoffs stop being enough.
Sometimes you do not need another software subscription or a six-month enterprise implementation. You need one focused application that removes friction, connects a workflow, organizes an event, or turns a recurring manual task into something reliable.
- 01Replace repetitive manual work
- 02Give administrators one place to manage operations
- 03Connect systems that do not naturally talk to each other
- 04Turn a useful idea into a working first version

From messy idea to useful software.
- 01
Discover
Understand the users, current process, pain points, and desired outcome.
- 02
Define
Agree on the smallest useful scope, milestones, responsibilities, and success criteria.
- 03
Build
Develop in visible increments with regular demonstrations and practical feedback.
- 04
Deliver
Deploy, document, hand off, and identify any worthwhile next improvements.
You do not need a perfect specification before we talk. You should understand the problem, who experiences it, and what better would look like.
Fit
A good fit when…
OptionStack Studio is intentionally focused on clearly scoped projects. It is not positioned as a large outsourced development team or open-ended enterprise transformation consultancy.
- A manual process is consuming too much time
- A spreadsheet has quietly become a business-critical system
- Existing software almost works but leaves an important gap
- An event or organization needs a custom operational workflow
- You need a focused MVP before investing in a larger product
- You have an existing application that needs a practical improvement
About
Built by someone who understands both software and organizations.

I’m Jerry Welch, an engineering leader and hands-on application builder. My professional work has included software delivery, cloud platforms, automation, quality engineering, AI-assisted development, and leading technical teams. Outside that work, I build focused products and applications for businesses, nonprofits, community organizations, events, artists, and occasionally my own strange ideas.
I’m most useful when someone understands the problem but needs help turning it into a clear scope and a working application.
