Profile

Software developer who builds websites and automates business workflows. For a client, I built and launched two websites with Next.js and serverless APIs, plus Zapier workflows that triage email with AI and generate weekly reports. My n8n demos show lead routing and CRM sync with replay and failure checks. I test my work, design it so a failed AI result is flagged to the team instead of failing silently, and use AI coding tools spec-first with every result reviewed.

1. 01

   Spec first

   I write down the inputs, outputs, and edge cases before building, then use AI tools like Claude Code, Claude, Codex, and ChatGPT against that spec and review every result.

2. 02

   Test the work

   Unit tests, browser QA, and real test runs before I call something done, not just a demo that worked once.

3. 03

   Fail loudly, not silently

   Gates before and after risky steps, so an invalid AI result or a failed write is flagged for a person instead of slipping through.

4. 04

   Verify the output

   A finished run isn't proof. I check the saved result separately and write down what was and wasn't verified.

5. 05

   Keep the team in sync

   Clear timelines, dependencies, and task breakdowns so developers, QA, and analysts know what's next.

What does John Mark Dela Cruz do?

He is a software developer focused on web development and workflow and AI automation. He builds and maintains websites and web apps, and automates business work such as form intake, AI inbox triage, CRM updates, and recurring reports.

Is he available for work?

Yes. He is open to full-time roles. He is based in Bacoor, Cavite, Philippines (GMT+8), and his recent roles have been remote.

What client work has he delivered?

On one DoGoodie contract he built two live websites, dogoodiebuilders.com and ethicalcapacitylab.org, plus two Zapier automations: an AI email inquiry classifier and a weekly KPI report. He is now a full-stack developer on iTip, a tipping platform in Kuwait, where the Payzah payment integration is still in progress.

Which tools and technologies does he use?

Next.js, React, and TypeScript on the front end; Node.js and serverless functions on the back end; Zapier, n8n, and the GoHighLevel API for automation; and AI coding tools such as Claude Code and Codex, with every result reviewed.

How does he check that his automations work?

He writes down the inputs, outputs, and edge cases first, adds gates before and after risky steps so an invalid AI result is flagged for a person, and checks saved results separately. Each case on this site lists what was tested and where its limits are.
