Jan Paolo Gabriel Supena

Senior Web Operations Engineer · Senior Web Developer · Customer Technical Support · AI Integration

Websites don't earn when they're slow, hacked, or down. For the past 8 years I've been the engineer accountable for making sure that doesn't happen. Owning live WordPress, WooCommerce and other framework sites end-to-end, from the checkout logic down to the server config underneath it.

That means both halves of the stack: the application layer — checkout and pricing logic, ACF/Gutenberg content systems, WPML multilingual, CRM and analytics integrations — and the Linux hosting, Nginx, Cloudflare, DNS, SSL, and caching underneath it.

AI integration

Practical, production features built with Anthropic Claude and OpenAI models — human-reviewed.

About

Operations first, development second

Plenty of developers can build a WordPress site. Far fewer will own it in production — be the one accountable when the checkout stops taking orders at 9 p.m., read the server logs to find out why, and fix both the symptom and the cause. That's the job I've done for 8 years at a web agency in Kitchener–Waterloo, across marketing sites, multilingual builds, membership and events platforms, and WooCommerce stores.

What makes that work is owning both halves of the stack: the application layer (checkout, pricing and cart logic, ACF/Gutenberg content systems, WPML multilingual) and the infrastructure underneath it (Linux, Apache, Nginx, Plesk, Cloudflare, DNS, SSL, caching, deployments). When something breaks, I don't hand it off between a "developer" and a "server person" — I'm both.

The other half of the job is the people side. For eight years I've been the person clients email when something is wrong — reproducing what they reported, working out whether it's a user, configuration, or genuine product issue, and explaining the answer in language that makes sense to whoever asked. Then writing it down, so the same problem doesn't cost anyone time twice.

Senior Web Developer / Web Operations Engineer — 2018 to present

Digital Chaos Inc. (web agency) — Kitchener, Ontario & remote

Sole engineer accountable for development, maintenance, incident response, and hosting operations across a portfolio of production WordPress and WooCommerce sites — spanning marketing, content, multilingual, membership, events, and e-commerce use cases.
Built and maintained WooCommerce customizations: checkout fields, pricing logic, cart behavior, product display, and order workflows for business-specific purchasing requirements.
Designed editor-friendly content systems with ACF Pro, custom Gutenberg blocks, and reusable patterns; supported multilingual publishing with WPML.
Supported marketing and CRM integrations, including HubSpot form embeds, Salesforce lead-capture handoffs, form field mapping, notification workflows, and troubleshooting of web-to-CRM submission issues.
Implemented and maintained analytics/tracking setups using Google Analytics and Google Tag Manager, including tracking scripts, conversion/event tracking support, campaign attribution, and validation of tag behavior across production pages.
Ran web operations on Linux hosting stacks: Apache, Nginx, Plesk, Cloudflare, DNS, SSL/TLS, security headers, redirects, and Git-based deployments.
Resolved production incidents — plugin conflicts, PHP errors, caching issues, DNS/SSL failures, broken checkouts, form submission issues, tracking-script problems, and CRM handoff errors — via server logs, WordPress debug logs, browser developer tools, Query Monitor, and structured testing.
Owned client-reported issues end-to-end: intake, reproduction, diagnosis, fix, validation, and a plain-language write-up of what broke and what changed.
Acted as the technical point of contact for non-technical clients and internal teams — clarifying requirements, guiding stakeholders through CMS and e-commerce workflows, and setting expectations on trade-offs and limitations.
Separated user and configuration issues from genuine application, integration, or infrastructure defects, escalating with reproduction steps and context when a fix belonged upstream; documented root-cause summaries and reusable troubleshooting patterns to cut repeat support effort.
Drove performance work from Google PageSpeed Insights findings into caching strategy, asset optimization, third-party script review, custom plugins, and server configuration.
Planned and executed migrations, redirect maps, data-structure changes, and integration updates with minimal downtime.
Integrated AI-assisted workflows (Claude, OpenAI) into planning, debugging, code review, QA, and documentation — with human review on all production decisions.

Handled systems administration for the servers and hosting environments behind the company's and clients' websites — the beginning of the infrastructure ownership that defines my work today.
