[The job post]: Title: Shopify store is slow, need speed optimization (mobile especially) We sell handmade ceramic tableware. Our store loads really slowly on phones and the PageSpeed mobile score is 31. We have a lot of apps installed (reviews, upsell, wishlist, currency converter, 2 popups) and big product photos. The theme is Prestige, customized by a previous developer 2 years ago. We want a better mobile score and faster pages without breaking the look. Budget: $300 fixed price Timeline: within 2 weeks Experience level: Intermediate Proposals: 20 to 50 Screening questions: 1. What PageSpeed score improvement can you guarantee? 2. Describe a recent Shopify speed project.

[Your profile and past work]: Shopify developer, 4 years freelancing, 38 jobs completed, Job Success Score 96%. Past work: 1. Speed fix for a supplements store on the Dawn theme: removed leftover code from 6 uninstalled apps, lazy-loaded images, deferred third-party scripts. Mobile LCP went from 6.8s to 2.9s and the PageSpeed mobile score from 28 to 61. Case study on my profile. 2. Product page redesign for a candle shop on the Prestige theme, with custom sections. 3. Replaced a heavy reviews app with a lighter one for a clothing store and cleaned app leftovers out of the theme files. Tools: Liquid, JavaScript, Chrome DevTools, Lighthouse, Shopify Theme Inspector.

[Your rates and terms]: $55 an hour. Fixed-price quotes come from my hour estimate at $55. Minimum project $250. Can start in 2 days, 20 hours a week available.

Example output

Shopify speed optimization proposal: ceramic tableware store, Prestige theme

1. Fit check

Fit: strong. Your supplements store speed job is nearly the same work: app leftovers, images and third-party scripts, with mobile score going from 28 to 61. Your candle shop redesign shows you know Prestige. Your reviews-app swap is relevant because they run a reviews app.
Red flags:

- The $300 budget covers about 5 hours at your rate, which is less than the full job needs.

- Screening question 1 asks you to guarantee a score, which no one can honestly promise.

- "Without breaking the look" may conflict with removing apps that add visible features, such as the popups and wishlist.

Angle: Open with their own setup (score 31, the app list, big photos, 2-year-old Prestige customization). Offer a measured first step on a duplicate theme. Prove fit with the 28 to 61 result. Make a paid audit-plus-quick-wins milestone the low-risk way in.

2. Proposal

A mobile score of 31 with reviews, upsell, wishlist, currency converter and two popups usually means the phone loads every app's script before the first ceramic photo appears. My first step: run Lighthouse and Shopify Theme Inspector on a duplicate of your Prestige theme, so you see what each app and image costs before anything changes.

I did this for a supplements store. I removed code left by 6 uninstalled apps, lazy-loaded images and deferred third-party scripts. Mobile LCP went from 6.8s to 2.9s, and the score from 28 to 61. Case study: [add link]. I've also built custom sections on Prestige, so I can work in its code without changing the look.

Plan: resize and lazy-load photos, defer scripts not needed on first view, clear old app code, then publish only after you approve the duplicate.

Questions:

1. Which apps must stay? Could one popup or the currency converter go? (Shopify Markets can convert prices natively.)

2. Has Prestige been updated since the customization?

3. Which pages matter most: home, collection or product?

Questions

Can I use ChatGPT to write Upwork proposals?

Yes, you can use ChatGPT or Claude to write Upwork proposals, as long as every claim is your real work. Generic AI proposals all open the same way, so give it the full post and your closest past jobs, and read the first two lines before you send.

How long should an Upwork proposal be?

A good Upwork proposal is short: often 120 to 200 words, with the first two lines about the client's problem, since those show in the client's list. This prompt also writes an 80-word version for posts with many applicants.

Should I bid lower than my rate to win on Upwork?

Cutting your rate to win usually attracts clients who keep pushing it down. This prompt prices at or above your floor, and when the budget is too small it offers a smaller first milestone instead, so the client can start without you working cheap.

Can I give a client my email on Upwork?

Not before a contract starts. Upwork's help center says sharing or asking for contact details before a contract violates its Terms of Service. This prompt keeps contact and payment on the platform for that reason.
