Building AI-era software that lasts.
Twenty-five years of engineering. I design and build complete, production-grade SaaS, on my own, from the database to the last pixel.
I'm Andrea Valla, a software architect with twenty-five years behind me. I design and build entire multitenant SaaS products end to end, alone: architecture, data model, security, payments, background work, monitoring. AI-native in how I work, classical in what I care about — systems that stay clean and legible as they grow.
One codebase serving many customers, each isolated. The hard part done right from day one.
Row-level isolation and least privilege in the database, not bolted on in the app layer.
Subscriptions, metering and invoicing that actually reconcile. Stripe, done properly.
Queues and jobs that carry the load off the request path and scale with it.
Email, push and in-app, wired so the right message reaches the right person.
Errors and performance watched from the first deploy, so problems surface before users do.
Chosen for reliability over novelty, and battle-tested across real products in production.
Software that ages well.
Anyone can ship something that works this week. The craft is in the code you can still read, extend and trust two years from now, after the roadmap has moved three times. That is what I build for.
