About
I build the unglamorous parts that make products dependable.
Most of my work sits between the interesting demo and the thing that has to work at 2am — hundreds of domains, scheduled jobs, permission models. That middle is where I like to be.
WordPress at network scale
A multisite estate plus 30+ custom plugins — lead capture, push notifications, consent banners, ad integration — without fighting the platform.
AI that survives production
Claude turning analytics telemetry into written insight reports, with prompt design and local model evaluation where privacy or cost demands it.
How I got here
I started in 2012 supporting PHP and WordPress platforms, then spent four years leading development for client sites at Tech Face Pro. Project management at Tech CASA taught me what breaks when architecture decisions are made without delivery pressure.
Since 2021 I have owned enterprise platforms end to end. Recent work spans a Laravel admin panel managing eight MySQL databases behind role and per-module permissions, a single Next.js app serving several hundred storefront domains, and a WordPress multisite estate I support with custom plugins rather than off-the-shelf ones. Scheduled jobs — uptime checks, queue-backed alerting, daily analytics aggregation — keep it running. I also mentor junior engineers and review code, which is the part of the job I keep coming back to.
This site is where I write about the decisions: what I shipped, what broke, and what I would do differently.

Selected work
Platforms built to be maintained, not admired.
A few engagements that show the range — multi-tenant platforms, admin tooling, WordPress estates, and AI-assisted analytics. Client names withheld; the architecture and the decisions are the point.
Multi-brand publisher network · 2025
One Next.js app serving hundreds of storefront domains
Replaced a fleet of near-duplicate brochure sites with a single tenant-aware Next.js app, so a new brand launches from config instead of a deploy.
- Modelled multi-tenancy around host resolution: one request, one tenant, no per-site deploy.
- Designed a Lambda-backed config service holding per-brand JSON — theme, copy, legal templates — with API-key auth and environment-scoped variants.
- Rolled GPC signal detection and a cookie-consent banner across the whole network.

Internal publishing platform · 2025
Role-gated admin panel over eight live databases
A single admin surface for content, configuration and monitoring across several brands — replacing scattered per-system tooling.
- Wrote role and per-module permission gates enforced in routes and reflected in the UI, so a user only ever sees modules their role allows.
- Connected eight separate MySQL connections from one service without leaking writes to databases the platform does not own.
- Added two-layer audit logging — a generic record plus per-module activity tables — so every change has an actor and a before/after.

Internal operations tooling · 2025
Uptime monitoring and traffic-spike alerting
Turned raw traffic into actionable alerts: hourly health checks, queue-backed ingestion, and rule evaluation that emails only when it matters.
- Drained a managed queue into an analytics table on a schedule, then evaluated rate rules across sites, URIs and single IPs.
- Kept alert noise down with per-rule thresholds and windows rather than blanket notifications.
- Added daily top-URL/URI/IP snapshots for the dashboard, plus retention handling so the table does not grow unbounded.

Revenue analytics dashboard · 2026
Claude-written insight reports from product analytics
Moved an analytics dashboard from showing numbers to explaining them — scheduled AI-written reports grounded in fetched telemetry.
- Aggregated two analytics sources into a repeatable fact table, so syncs are idempotent and safe to re-run.
- Sent a 30-day summary to Claude and stored structured insight output: what is working, where the opportunity is, and what the data cannot answer.
- Respected source rate limits with a deliberate cooldown instead of hammering the API on every dashboard load.

Publisher network, WordPress estate · 2023
Thirty custom plugins for a WordPress multisite estate
Replaced a scatter of one-off fixes with a maintained plugin suite — lead capture, notifications, consent, ads and tracking across every site.
- Built lead-capture, push-notification, ad-server and consent-banner plugins against a shared multisite pattern.
- Wrote authenticated quiz and trivia experiences with Firebase behind them, rolled out across brands from one codebase.
- Automated domain and environment replication so new sites inherit tracking and privacy configuration correctly.

WordPress multisite to headless Next.js
Moved a multi-site WordPress estate to a headless front end behind a REST boundary, keeping editors on the workflow they already knew.
- Kept WordPress as the content system of record while React/Next.js served the public face.
- Exported content straight from the multisite database with a purpose-built automation, including a stale-lock release step.
- Migrated incrementally by site rather than big-bang, so revenue pages stayed up throughout.

Experience
Nine years, four rooms, one continuous thread.
From maintaining PHP sites to owning AI features on enterprise platforms. Each role added a layer I did not have before.

CurrentSoftware Engineer
OPK E Services
Own enterprise web platforms end to end — a Laravel admin panel, a multi-tenant Next.js storefront network, and WordPress multisite estates — with AI integration layered on top.
- Built an internal admin panel in Laravel that manages a WordPress multisite network and five email content engines across eight separate MySQL databases, gated by role and per-module permissions.
- Designed the multi-tenancy layer for a single Next.js app serving several hundred branded storefront sites, each resolved from its own domain and driven by a Lambda-backed config service.
- Wrote 30+ custom WordPress plugins — lead capture, push notifications, ad and tracking integration, consent banners, and authenticated quiz experiences.
- Built the scheduled processing behind it: uptime monitoring, traffic-spike alerting off an SQS queue, and daily analytics aggregation running on hourly and daily artisan schedules.
- Integrated Anthropic Claude to turn GA4 and Clarity telemetry into weekly written insight reports, plus OpenAI and Ollama for content generation and privacy-sensitive local inference.
- Migrated WordPress estates to headless React/Next.js frontends over REST APIs, and tightened latency with caching strategies, async processing, and deliberate rendering budgets.
- Mentored junior engineers and ran code reviews across the team.
