What I Do

I work on WordPress and WooCommerce systems where correctness, performance, and long-term maintainability matter. My focus is not just building features, but ensuring they work reliably in real production environments.

Custom Plugin Development

Designing and building WordPress plugins with clean architecture, secure data handling, and extensibility in mind.

API Integration & Data Synchronization

Integrating third-party services using REST APIs, handling authentication, data mapping, and synchronization between external systems and WordPress.

E-commerce Systems & WooCommerce

Developing and maintaining checkout, cart, and order-related features where stability directly impacts revenue.

Production Maintenance & Optimization

Debugging legacy systems, improving performance, and making pragmatic engineering decisions under real constraints.

Selected Work

Evidence of judgment, responsibility, and real-world problem solving across production WordPress and WooCommerce systems.

WooCommerce Side Cart Plugin

Himuon Flex Cart (WooCommerce Side Cart Plugin) Designed and built a production-ready WooCommerce side cart focused on fast UX and extensibility. Implemented AJAX-driven cart interactions for quantity updates, item removal, variation editing, subscription option handling, coupon apply/remove flows, and free-shipping progress updates with real-time fragment refresh. Architected the plugin around modular PHP classes, template rendering, and hook/filter-based customization to avoid hardcoded admin settings and support developer-level control. Owned end-to-end reliability and maintainability concerns including input sanitization, output escaping, i18n compliance, fragment performance tuning, mobile behavior fixes, and release-readiness for plugin submission.

Klaviyo Integration for Gravity Forms

Designed and built a Gravity Forms add-on that integrates form submissions with Klaviyo’s profile and list APIs. Implemented a feed-based configuration model, secure API key management, field-to-attribute mapping, and validation of external dependencies. Owned the full submission lifecycle, including profile creation and updates, list subscription, entry-level status tracking, and manual re-sync tooling for failed operations. The integration was designed to operate reliably within Gravity Forms’ add-on architecture while providing administrators with clear visibility and recovery controls.

Image Metadata Generator AI

Built a WordPress plugin that automates the generation of SEO-friendly image metadata by integrating OpenAI directly into the Media Library workflow. Implemented a settings interface for secure API key storage and validation, added a custom action within attachment details, and handled end-to-end metadata updates for alt text, titles, captions, and descriptions in a single request. Designed the plugin to integrate cleanly with WordPress core media fields while keeping the workflow simple and editor-friendly.

Forge+ WooCommerce Store for Strength Equipment

Designed and implemented a demo WooCommerce e-commerce store for a professional strength equipment brand concept, focused on selling heavy, commercial-grade products to both home gym and facility customers. Built the store on top of WooCommerce while customizing product presentation, cart behavior, and purchasing flows to reflect real-world considerations for weight-based items, pricing clarity, and buyer confidence. Structured product pages to emphasize durability, specifications, and usage context, and implemented cart and checkout flows that account for heavy-item concerns such as shipping expectations, fees, and delivery handling. Although created as a demo, the system was built to mirror production-ready e-commerce patterns, prioritizing clarity, reliability, and a friction-free purchasing experience.

Add to Cart Anywhere (Impreza Extension)

Built a custom WordPress plugin that extends the Impreza/US Builder by registering a new element for rendering WooCommerce add-to-cart forms anywhere on a page using a specified product ID. Integrated directly with Impreza’s element registry and template resolution system, while leveraging WooCommerce’s native add-to-cart templates to maintain compatibility with product types, stock rules, and core behavior. Implemented configurable UI controls for button labeling, sizing, quantity styling, and layout, with graceful handling of invalid or missing product states.

Focused on clarity, accessibility, and reliability for non-technical users interacting with the site.

Vesl Oils — WooCommerce E-commerce Platform

Built and maintained multiple WooCommerce-based e-commerce stores for the same business over a five-year period. Initially developed the stores using an existing theme and plugin ecosystem, then implemented extensive custom functionality, including fully customized add-to-cart behavior across shop, category, and single product pages. Owned the long-term maintenance, feature updates, and system stability of live production stores. Some storefronts were eventually discontinued due to business performance, while the primary store continued to operate as a revenue-generating platform.

Simple Customer Wishlist

Built a lightweight WooCommerce wishlist plugin to address the limitations of existing solutions that were heavy or overly complex. I designed and implemented the plugin from scratch, focusing on clean architecture, minimal performance overhead, and long-term maintainability. The plugin is fully internationalized, compatible with common WordPress tooling, and published in the official WordPress plugin repository.
