About Sequential
Alan De La Cruz
Founder
Who I Am
I'm a working statistician and data engineer with graduate training in neuroscience, research methods, and a professional background in occupational safety — who builds custom data systems for businesses.
That combination — understanding what the data actually means and being able to build the software to capture, process, and present it — is rare. It's the foundation of everything Sequential does.
I started Sequential because I saw the same problem everywhere: companies drowning in spreadsheets, paper forms, and disconnected tools, with no one who could both understand their data problems and build the actual systems to solve them. Not a slide deck about solving them — the actual working systems.
My flagship project, the Custom Sales App, is proof. I took a 12-office industrial equipment company from paper forms and manual data entry to a full production application — forms, calculations, approval workflows, executive dashboards — built and delivered by one person.
Background
How I Work
Project-based engagements with milestone structure. Clients own everything — all code, all data, all deliverables.
Understand the problem, the workflow, the people, and the data. Map what exists and what's needed.
Clear scope document with deliverables, timeline, and pricing. No ambiguity. 50% deposit to start.
Design, develop, and iterate. Regular check-ins, milestone reviews. No black-box delivery.
Delivered with a playbook and walkthrough. You own the code, the data, everything. No lock-in.
What I Believe
No vanity dashboards. No reports that sit in inboxes. If a system doesn't change how you work, it's not a solution.
If a spreadsheet is costing you hours every week, that's a system waiting to be built. Start with the pain, not the technology.
No handoffs between the strategy person and the dev team. One person who understands the data and builds the system. That's the advantage.
Every project produces a working system, not a deck. Production code, documented, deployed, and owned by you.
Tell me about the problem. I'll tell you what it takes to solve it.
