About Paul DeSalvo
A background in data. A focus on reliable systems.
I build data systems and applications that turn complex requirements into reliable tools. My background is in data architecture and engineering, and my work now spans operational applications, reporting, and AI workflows.
I write about architecture, working with AI, and the decisions that keep software useful and practical to maintain.
Data, apps, cloud, and AI
Practical systems that help people make decisions and get work done.
How I Got Here
Data architecture taught me to look closely at how a business works: where information comes from, what it means, and who depends on it. That understanding helps me build systems that support real decisions and everyday work.
That is why my work keeps expanding past pipelines and reports. Once you understand the data, you start seeing the workflow. Once you understand the workflow, you start seeing the tool that should exist. And once the tool exists, you have to make it reliable enough for people to trust.
Good systems make important work easier to do and easier to keep doing.
What I Bring Together
These three areas shape both how I build and what I write about.
Architecture
Understand the data, choose foundations that fit the problem, and weigh the cost and responsibility of running the system.
Reliable Systems
Turn requirements into useful applications, verify how they behave, and keep them understandable and practical to maintain.
Working With AI
Use context, clear responsibilities, and repeatable checks to help agents carry work from an idea through to a dependable result.
I Also Ship My Own Products
Alongside my professional work, I build my own products. They give me room to explore ideas and take responsibility for the whole application, from early experiments to release and upkeep.
Range of Motion Tracker
A full-stack telehealth app for physical therapists, with pose detection, remote sessions, patient workflows, reporting, and AWS infrastructure.
Little Learners Lab
A shipped App Store education app with bilingual English and Spanish games, privacy-first design, and no accounts, ads, analytics, or tracking.
Enterprise Systems
Production work across cloud platforms, data products, operational apps, governed analytics, and AI-assisted decision workflows.
How I Work
I start with the requirement and the constraints, make experimentation cheap, and check the result against the work it needs to support. Maintenance is part of the design from the start.
