Make the foundation trustworthy
Connect the source systems, define what the data means, and settle who can see and change it before anything is built on top.
Hi, I’m Paul. I build complete applications: the interface people use, the data underneath it, and the checks that keep it working.
What I Build
From complex requirements to working systems.
I work from the initial problem through architecture, implementation, and verification. AI agents carry much of the build; I define the decisions and the checks. The aim is software that fits the work, handles everyday use reliably, and stays practical to maintain.

Turn the workflow into software
Build the application around the people using it: the screens, the steps and the reports they need to do the job.
Flow
Keep it working after launch
Deploy it, check the results against what was asked for, and leave it practical to change, with clear points for human judgment.
Field Notes
Architecture, working with AI, and reliable systems.
I write about the decisions that keep software useful and practical to maintain, with explanations and examples from my work.
Practical systems that help people make decisions and get work done.
About Paul DeSalvo
From data engineering to complete applications.
My background in data architecture shapes how I build applications: understand the business, make the data trustworthy, and choose foundations that fit the problem. Those habits carry across clouds and frameworks, and AI lets me take more of the work through to a complete, usable system.
Good systems make important work easier to do and easier to keep doing.
Follow the problem end to end.
Keep the data and permissions trustworthy.
Ship the usable version, then improve it.
Keep systems understandable and practical to maintain.
