Not Your Average eCommerce

Highly effective eCommerce products are built for precision, integrating directly with payment processing systems like Stripe. I build custom eCommerce systems with WordPress that put simplicity, speed and scalability where they belong: as top priorities.

  • Custom Onboarding Generic checkout flows cost you sales. I build eCommerce systems that support precise product purchasing flows tailored to your specific user journey.

  • Zero Plugin Dependency Plugin-heavy sites are technical debt waiting to happen. I engineer minimal systems designed to last, avoiding the bloat that cripples standard WooCommerce sites.

  • Purpose-Built Architecture Standard themes cannot handle complex functionality. I apply high-value engineering to custom applications, shifting investment to upfront architecture for long-term stability.

  • AI Enhanced Manual workflows create unnecessary overhead. I integrate APIs from OpenAI, Anthropic, and Gemini to handle complex tasks in new, novel, and automated ways.

  • Custom Analytics & Logging Third-party platforms obscure your data ownership. I provide transparent reporting and automated measurements using your own first-party data to ensure you own your insights.

  • Form Management Spam submissions clutter your sales pipeline. I build lead generation forms specifically for your business that successfully identify and block 100% of spam using AI.

  • Growth Strategy Guesswork leads to product stagnation. I provide sound strategic advice on SEO, content marketing, and design to build mechanisms that drive rapid growth.

  • Exceptional Design Standard templates fail to convert users. I leverage years of UI design experience to build elegant, simple systems that drive higher conversion rates than off-the-shelf solutions.

  • Precision Server-Side Tracking Ad-blockers render client-side analytics inaccurate. I define server-side tracking in the exact places you need it, ensuring 100% data accuracy regardless of user settings.

  • Advanced ACH Handling Bank delays and settlement risks complicate cash flow. I implement expert ACH debit/credit logic that automatically handles the nuances of delays and financial risk.

Fractional Engineer/CTO

I augment your existing team, or become it, by dedicating a range of hours per month toward your project. I don't spread myself thin across dozens of projects at once. I am a reliable partner with the high-level skills of an experienced consultant, but the reliability and dependability of a full-time team member, at a fraction of the cost.

Custom WordPress architecture focused on code quality and scale.

Common Questions on Custom eCommerce Architecture

If you're weighing the decision between a plugin-heavy build and a custom architecture, these are the technical realities you need to consider for high-scale environments.

Do you use WooCommerce to build these "custom eCommerce engines"?

No. I build code-based online flows that directly integrate with Stripe and other payment processing providers. I use custom database schemas to store logs and relevant data securely and compliantly. The systems I build are never 'out of the box.'

Why not use WooCommerce or subscription plugins?

WooCommerce is technical debt waiting to happen. Its database schema relies heavily on wp_postmeta, creating a messy, unscalable structure where every order adds dozens of rows of unindexed data. On top of that, the plugin ecosystem introduces constant vulnerabilities. My approach builds Lean, Purpose-Built Applications that happen to run on WordPress, creating a stable environment without the bloat.

I've heard WordPress has scale problems. Why use it?

Standard WordPress has scaling limits regarding the wp_users and wp_posts tables. That is why I don't use them for high-volume data. I handle custom user management outside of the standard WordPress user table, defining a custom database schema ideally suited for your data. This makes user management as lean and scalable as any Laravel application, handling millions of users if necessary.

We have thousands of products. How do you handle that?

I use a 'Variable Price Product' pattern. Instead of syncing 10,000+ items to Stripe (which is unmanageable), we generate a single 'Master Product' in Stripe and dynamically pass details (price, name, metadata) into the Checkout Session. This powers catalogs of 10,000+ items with zero friction, avoiding the server crashes common with large WooCommerce catalogs.

With a custom system, how do we handle reporting?

Reporting is faster and leaner. Because we use a minimal set of custom tables, we can write precise SQL queries to generate reports instantly. This avoids the 'SQL abuse' of standard plugins, keeping server costs down and preventing the database freezes that plague decent-sized eCommerce sites.

How do you monitor for transaction issues?

I build custom database tables to log raw data from Stripe webhooks. I then build custom dashboards that act as a 'translation layer,' making the data simple to interpret and helping you avoid false positives found in raw logs.

Is it possible to accept ACH payments to save fees?

Yes, but the challenge is the delay in confirmation. ACH can take days to settle. I build custom logic to handle these 'pending' states, ensuring you don't grant access to high-value products until the funds are truly secured.

How do you handle transactional email?

I utilize WordPress's built-in SMTP system (without heavy plugins) integrated with Microsoft 365 or Google Workspace for standard volume, or AWS SES for high-volume, low-cost delivery. I also build tools allowing you to manage email text while I handle the code and delivery reliability.

Why not just use Laravel or React?

Those frameworks often require keeping developers on staff just to manage daily operations. With my Hybrid WordPress Approach, we create management tools for you to control your business, while using lean, smart code to keep maintenance virtually zero. You get the flexibility of the world's most popular CMS with the performance of a custom application.
