Selected Case Studies

I build custom Shopify and WordPress storefronts focused on real-world results: passing Core Web Vitals, cutting app bloat, and creating smooth checkout experiences.

Faster Mobile Load Times via Smarter Image Delivery

Default store settings often let unoptimized media slow down mobile shoppers. By revamping how assets are handled, I reduced image payloads by up to 80%.

  1. Modern Formats: Converted heavy legacy assets into lightweight WebP files.
  2. Responsive Sizing: Set up srcset rules to serve properly scaled images based on the user's screen size.
  3. Lazy Loading: Deferred off-screen images so the visible page renders immediately.
  4. CSS Replacements: Replaced purely decorative images with clean CSS and lightweight SVGs.

Eliminating Repetitive Store Tasks with Reusable Metaobjects

Manually updating shared details like ingredient lists across dozens of products is slow and prone to mistakes. By restructuring product data, I turned days of repetitive copying into a simple two-hour fix.

  1. Metaobject Setup: Created a central "Ingredient" metaobject to store descriptions, tags, and images in one structured place.
  2. Product Metafields: Linked products dynamically to existing ingredient entries instead of hardcoding text into individual theme blocks.
  3. Dynamic Liquid Sections: Built an automated frontend template that pulls linked data wherever it needs to appear across the site.

Custom Tools & Automation

Image Optimization & AI Tagging Pipeline

Preparing catalog imagery by hand—cutting out backgrounds, compressing files, and writing SEO tags—takes hours. By connecting a Python workflow with multimodal AI vision APIs, I turned a multi-step manual editing chore into an automated, zero-touch pipeline.

  1. Automated Background Removal: Programmatically isolated subjects and created clean transparent PNGs in bulk without paid software subscriptions.
  2. Batch WebP Compression: Converted high-res source files into optimized WebP formats to keep catalog weight low.
  3. AI-Powered Metadata: Analyzed image contents on the fly to auto-generate accurate product descriptions, alt text, and search tags.

Performance Diagnostics & Web Vitals Engine

Store audits should spend time solving checkout friction and layout issues, not wasting hours manually writing down scores. By building an automated benchmarking engine, I eliminated manual data collection so I can jump straight into actionable fixes.

  1. Automated Telemetry: Queries API endpoints across multiple device profiles to log Core Web Vitals (LCP, CLS, INP) in seconds.
  2. Headless Diagnostic Scans: Runs headless browser sessions to highlight render-blocking scripts, heavy third-party tags, and shift sources.
  3. Structured Audit Reports: Turns raw performance benchmarks into readable summaries ready for client review.
