Mobile App Development

Native iOS and Android apps, or cross-platform builds with Flutter and React Native — polished on every device.

API Design & Integration

RESTful and GraphQL APIs from scratch, plus seamless integrations with Stripe, Salesforce, QuickBooks, and more.

Software Modernization

Replatform legacy systems and migrate monoliths to microservices — without disrupting day-to-day operations.

Our workspace

Texas-built software, straight-talking delivery

Founded in San Antonio, Alexander Data Solutions is a boutique software shop that punches well above its weight. We pair enterprise-grade engineering with the kind of direct, honest relationship style you'd expect from a neighbor — no runaround, no surprise invoices.

We don't outsource your trust. Every project is handled by a senior engineer who cares about your outcome as much as you do.

Why Alexander

We write real code and take real ownership

01

Product-minded engineering

We think like founders, not just coders. Every feature is weighed against business value, not just technical elegance.

02

Full transparency

Live project boards, weekly demos, and direct access to your developer. You always know exactly where things stand.

03

Code you can own

Clean, documented, test-covered codebases your internal team can confidently inherit, extend, and maintain.

04

No revolving door

Senior developers own your project start to finish. The person who scopes your app is the person who ships it.

Aggregated client outcomes, 2022–2025

A proven path from idea to production

1

Discovery

We dig into your requirements, map existing systems, and align on scope, stack, and success metrics before a line of code is written.

2

Architecture

We design the technical blueprint — schemas, API contracts, service boundaries — and validate it with you before building.

3

Build & Ship

Two-week sprints with live demos. You see and test working software at every stage, not just at the finish line.

4

Launch & Support

We deploy, monitor, and stay on hand post-launch. As your product grows, we're ready to scale right alongside it.
