How I work
A process built to remove ambiguity: you always know what is being built, what it costs, and when it lands.
A free 30-minute call to understand the goal, the constraints, and what success actually looks like.
You get a written summary of the scope and a fixed price before any code is written — no open-ended hourly surprises.
I map the data model, the plugin boundaries, and every third-party API before touching the theme.
Deliverables are broken into milestones, so you can see exactly what ships when and sign off in stages.
Clean, documented PHP and JavaScript committed against a staging site you can click through at any time.
Coding standards, escaping, nonces, and capability checks are handled as I go — not retrofitted at the end.
Deployment, performance pass, and a walkthrough recording so your team can run it without me.
Optional maintenance covers updates, monitoring, and small changes after launch.
Capabilities
The work that tends to land on my desk — and the numbers that come out of it.
Purpose-built plugins with clean architecture, hooks other developers can extend, and no dependency on a page builder.
Checkout flows, multi-vendor commission logic, subscriptions, and catalog pipelines that survive real traffic.
OpenAI-backed content tooling, embeddings, and editorial workflows wired into the admin your team already uses.
Query tuning, object caching, asset budgets, and measured before/after Lighthouse runs on real hardware.
Custom REST endpoints, CRM and ERP connectors, and React frontends reading WordPress data over the wire.
