Good day, I have been developing and maintaining websites on OpenCart for more than 8 years. I am ready to complete your order; optimization is a standard task, and we perform it from the start during development. I also have experience in ongoing maintenance, currently managing 3 online stores, the largest with 80,000 products. I will provide examples of my work in private. Write to me, and we will discuss!

Hello!
I have been working with OpenCart for 15 years.
I write clean code, without hacks and bugs.
Everything is strictly according to OpenCart documentation.
I work with any API, writing custom modules of any complexity.
I only work within agreed budgets (not by hours), I do not raise rates during the process.
I work with quality, hence it takes a little longer.
I am ready to discuss the details.

Good day!
I have carefully reviewed your technical assignment. The task is completely clear to me: you have ocStore 3.0.3.2, and the main priority is the stability of the server and database, not just "green numbers" in PageSpeed.
I specialize in OpenCart 3.x and have experience working with high-load stores. I am ready for long-term cooperation and phased work.
My comments on the points of your technical assignment:
1. Stability and Server (Backend)
You are absolutely right, starting with this point. The "temporary instability" you mention is most often caused by locks in MySQL and heavy queries.
• My approach: I will start with analyzing the slow_query_log of MySQL and optimizing the database indexes. I will also set up Object Cache (Redis), which is critically important for ocStore 3 — this will relieve up to 50% of the load from the database.
2. Safe Caching
I see your requirement: caching should not affect the cart and prices.
• Solution: I will configure caching with exceptions (hole punching) for dynamic blocks (mini-cart, personal account, session tokens). This ensures that the customer always sees the current price and availability.
3. Microdata and SEO
I will implement JSON-LD (Schema.org) for products, breadcrumbs, and organization, as specified in the technical assignment. This will be done programmatically at the controller level so that the data is pulled dynamically and without Google validation errors. I will also set up Open Graph for correct reposts on social media.
4. Frontend and PageSpeed
To speed up the mobile version:
• I will implement the WebP format for images.
• I will set up Lazy Loading for images below the first screen.
• I will change JS scripts to defer mode so that they do not block the rendering of the page.
