Latency
Excessive third-party JavaScript injection blocks the main thread. I diagnose the root cause of degraded LCP and INP — the metrics that directly determine your Core Web Vitals score.
I surgically remove app bloat and rebuild your Shopify store with native code. No monthly fees, no external dependencies, no more explaining to the CEO why the site is slow.

You're paying monthly fees for features Shopify now includes. I migrate you to native code so you stop paying rent.
"Ghost code" from uninstalled apps creates 404 errors and dependency risks. If an app server fails, your store breaks.
You're managing agencies, approving app installs, and shipping promos weekly — while your checkout breaks because two apps conflict in the DOM. You need someone who fixes the infrastructure so you can focus on growth.
I don't add features. I remove friction. I transition you from a 'renter' to an 'owner'.
Focus: Native Shopify Architecture — Functions, Metaobjects, OS 2.0
I conduct a rigorous investigation to identify ghost code, script impact, and redundancy.
I surgically remove high-cost, high-drag apps and rebuild features using native Liquid/JS.
I convert deprecated Shopify Scripts to native Functions (Rust/WASM) before the June 2026 shutdown.
Ongoing protection against "re-bloating." I act as your technical gatekeeper.
I separate the display layer from the service provider. Reviews render instantly via native Metaobjects; heavy third-party scripts load only when the user opens the submission form
I use the IntersectionObserver API to defer marketing scripts until users engage, eliminating TBT penalties. (Klaviyo, Attentive).
I replace client-side "Smart Cart" apps with the Cart Transform API. Bundling and upsell logic executes on Shopify's infrastructure (WASM), not the user's browser.
Agencies rent you a process. I build you an asset. When you hire FosterUI, you get me, not a junior developer, not a dedicated account manager, and not a game of telephone. One line of communication, one engineer, zero layers — no waiting for your agency to loop in their developer who subcontracted the work to someone else.
I personally audit, refactor, and govern your codebase.
// FosterUI Operational Config const agency_model = null; const architect = "Me"; async function initProtocol() { if (bloat_detected) { await architect.removeDependencies(); return "Native Architecture Restored"; } }
