Jason Guijo

I build and automate enterprise systems that make work easier for the people using them.

Build

Web applications, dashboards, and workflow systems.

Validate

Playwright E2E testing and system-log analysis.

Integrate

SAP, Microsoft Graph, SCADA, and cloud services.

Selected systems, built for real work.

Three examples of operational software, integration work, and delivery decisions. Full evidence stays in the project index.

01 / 05

Integration / .NET

Batch runs record automatically instead of being entered twice.

Web app / Next.js

Role-based access and AI-assisted ticket summaries support daily IT work.

Dashboard / React

Work orders, status, reporting, and backup workflows stay visible together.

Web app / NestJS

Distinct user roles, queues, and document delivery make approvals traceable.

Workflow / automation

Searchable records and integrations replace multi-step paper handling.

Boot sequence

01
Scope
We talk through the problem. I tell you honestly what's worth building, what isn't, and what it will realistically take.
02
Build
I build it solo, end to end — with regular updates in plain language. No jargon, no black box, no waiting to see progress.
03
Deploy
I ship it to production and make sure it works in your real environment, with your real data — not just on my machine.
04
Hand off
Documentation, a walkthrough, and support after launch. You are never left holding something you can't run yourself.
System live

I build, ship, and improve useful software for businesses, teams, and individuals. Tell me what you want to make easier.
