Database engineering
Your data, organized. Queries that finish on time. Migrations that don't lose anything.
Examples: Postgres design from scratch, MSSQL tuning, full ETL migrations
I help small businesses and growing companies build the systems they actually need - databases, web apps, IT infrastructure. No bloat. No drama. No 12-person meetings.
Each engagement starts with a written scope and a fixed price. You know what you're getting before we begin.
Your data, organized. Queries that finish on time. Migrations that don't lose anything.
Web apps and internal tools that fit your business. Built to be used daily, not parked after a demo.
The plumbing nobody wants to think about - email, DNS, hosting, backups. Done once. Stays done.
I'm Andres. NanoScript is my engineering practice for projects outside my full-time job. I work with clients internationally - US-based companies on contract plus a portfolio of my own SaaS platforms.
I started at Cottonimages.com, a photo studio and reseller - four years as a multi-hat manager doing IT, purchasing, inventory, and operations. They're still a NanoScript client today; that working relationship has spanned over 10 years across both roles.
After that, one year of IT at a healthcare network in South Florida. Then five years at a legal-tech SaaS where I started in tier-3 support and finished as a developer over the last two years there. Today I'm Senior Developer at an enterprise software company focused on Active Directory and Microsoft 365 governance.
If you'd rather have one experienced engineer who owns the whole thing than a five-person agency that hands it off twice, we'll get along.
Same process whether the project is two weeks or six months. No surprises, no hidden invoices.
30 minute call. I ask questions. No deck, no pitch.
Written proposal with milestones, deliverables, and a fixed price.
Weekly demos. You can redirect at any milestone.
Runbook included. 30 days of post-launch support.
Multi-tenant SaaS platform for service businesses (clinics, salons, mobility). Booking, scheduling, customer accounts. Live at clickpro.app.
Multi-tenant work-log SaaS for cuadrillas and contractors. Mobile PWA + admin approval inbox + photo evidence + payroll ledger + auto-LABOR + materials/vendors/invoices. Migrated from a legacy app with zero data loss.
Idempotent PowerShell + Microsoft Graph automation managing catch-all mail across 17 domains. DKIM, DMARC, transport rules, version-controlled and re-runnable.
Lead developer for Active Directory governance products serving enterprise customers. Architecture, OData APIs, .NET migrations, customer escalations.
Long-running engagement that began with operations work (multi-hat manager) and grew into ongoing IT and engineering support. Continuous client of NanoScript since the practice started.
One short call, no pitch deck. If it's a fit, we'll write up a scope. If it's not, I'll point you somewhere better.
