COMMERCE SYSTEMS

Overview

Platforms, catalogs, pricing, checkout and the systems that keep commerce coherent.

What it is

Commerce systems connect product data, inventory, pricing, merchandising, checkout, payments and external services into one dependable storefront. The platform matters, but the architecture between those pieces matters even more.

Why it matters

A storefront can look fine while pricing drifts, inventory desynchronizes, checkout customizations break upgrades or catalog rules quietly become impossible to maintain. Commerce failures tend to surface at the worst possible moment: when real customers are trying to buy.

Why experience matters

Experienced implementation means knowing where to extend a platform and where not to, how indexing and cache layers behave, how checkout changes affect upgrades, and how Magento, BigCommerce, Shopify, WooCommerce and custom systems differ under load.

TYLER PFLANZ / CAPABILITY 02

JAVASCRIPT

Overview

Browser, server and application JavaScript, from interaction details to full application architecture.

What it is

Modern JavaScript is the runtime behind rich interfaces, application state, asynchronous data flows, server-side services and increasingly complex browser behavior. TypeScript, React, Next.js, Node.js and animation systems are tools inside that larger runtime.

Why it matters

Poor JavaScript architecture creates race conditions, stale state, memory leaks, oversized bundles, fragile interactions and bugs that only appear after a user has been on the page for five minutes. Those problems are difficult to diagnose after the architecture is already entrenched.

Why experience matters

A strong developer recognizes when complexity is justified, chooses stable state and data boundaries, keeps rendering predictable, understands browser behavior, and can make sophisticated interaction feel fast without turning the codebase into an animation experiment.
×

×

TYLER PFLANZ / CAPABILITY 03

BACKEND / DATA

Overview

PHP, MySQL and the data layer where correctness, performance and durability actually live.

What it is

Backend and data systems own business rules, persistence, transactions, jobs, caches and the APIs that other systems trust. PHP and MySQL can power extremely large applications when schemas, queries and execution paths are designed deliberately.

Why it matters

A weak data layer creates slow queries, locking, duplicated records, unsafe migrations, cache inconsistency and failures that cannot be fixed in CSS or JavaScript. The cost of a bad schema usually increases with every feature added afterward.

Why experience matters

Experience shows up in indexing strategy, transaction boundaries, query plans, schema evolution, queues, caching, failure recovery and knowing when a database problem is actually an application-design problem.
×

×

TYLER PFLANZ / CAPABILITY 04

INTERACTIVE WEB

Overview

WebGL, Three.js, Canvas, shaders and realtime visual systems that still have to behave like websites.

What it is

Interactive web graphics use the GPU and realtime rendering loops to create depth, motion, particles, 3D scenes and interfaces that normal DOM/CSS cannot reproduce efficiently. They can be cinematic without becoming a disconnected demo.

Why it matters

Realtime graphics can burn battery, leak GPU memory, destroy mobile frame rates or block accessibility if they are treated as visual decoration first and software second. A scene that runs at 60fps on one desktop can collapse on a phone.

Why experience matters

An experienced developer budgets render work, manages resources, controls pixel density, understands shaders and draw calls, builds fallbacks, and integrates the effect with normal content instead of letting the effect become the product.
×

TYLER PFLANZ / INTERACTIVE WEB

WebGL

What it is

A browser graphics API that uses the GPU to draw interactive two-dimensional and three-dimensional scenes.

Where it fits

×

TYLER PFLANZ / CAPABILITY 05

INTEGRATIONS

Overview

APIs, feeds, webhooks and automation, the invisible connections between otherwise separate systems.

What it is

Integration work moves reliable data between storefronts, ERPs, PIMs, search engines, warehouses, vendors and custom services. The visible API call is usually the easiest part; the real system is everything around it.

Why it matters

Networks fail, providers throttle, payloads change and the same event can arrive twice. Without idempotency, retries, reconciliation and observability, an integration can appear healthy while silently losing or duplicating business-critical data.

Why experience matters

Good integration engineering anticipates partial failure, rate limits, ordering, schema drift and recovery. It creates a system that can explain what happened after something goes wrong instead of merely logging “request failed.”
×

TYLER PFLANZ / CAPABILITY 06

FRONTEND / PERFORMANCE

Overview

HTML, CSS, accessibility and performance, the layer every user actually experiences.

What it is

Frontend performance is more than a Lighthouse score. It combines semantic HTML, responsive CSS, asset loading, rendering behavior, accessibility, technical SEO and interaction quality into a page that remains fast under real conditions.

Why it matters

A page can be visually impressive and still shift while loading, block keyboard users, waste bandwidth, bury content from search engines or feel sluggish on average hardware. Small frontend mistakes compound across every page view.

Why experience matters

Experience means understanding the browser pipeline, CSS architecture, layout stability, font and image loading, Core Web Vitals, accessibility semantics and how to preserve visual ambition without making the user pay for it.
