  • Development of a price and stock update module for OpenCart 3

    Web Programming
    Development of a price and stock update module for OpenCart 3 — example of freelancer's portfolio work in category Web Programming
    The client needed a commercial module for automatic price and stock updates on OpenCart 3.0. The task involved working with large data arrays, validating files, implementing security measures, and ensuring stable execution of updates in CRON mode.

    I developed the module from scratch: I designed the architecture, added several levels of checks, security mechanisms, logging, error management, and notifications. I optimized the import for handling large files and ensured full compatibility with the client's template.

    … Result: the module reliably updates data without operator intervention, works quickly and without failures, and exceeded the initial requirements of the technical specification in terms of quality and functionality.

    ==================================================================

    Client's feedback:
    "The work was done excellently. The module for OpenCart 3.0 fully meets the standards of commercial development, and in some aspects even exceeds the requirements of the technical specification. The programmer took care of security, implemented additional protection mechanisms, and approached all technical details very responsibly. All corrections were made quickly, communication was at a high level. I definitely recommend collaborating!"

    Payment Systems Integration
    WooCommerce cart setup + InPost and Autopay integration — example of freelancer's portfolio work in category Payment Systems Integration
    The client reached out with a problem regarding the incorrect functioning of the cart and unstable integration of delivery and online payment modules. Some orders were not going through, and purchase notifications were not reaching either the clients or the store managers.

    I completely restored the Checkout logic, configured the correct operation of the InPost API, integrated the Autopay payment service, and organized email notifications. I also optimized the checkout process, removed conflicting plugins, and conducted testing of all order scenarios.

    … Result: the cart started working stably, payments are processed without failures, and both the client and the team receive instant notifications. The order processing time has been reduced, and the number of successful transactions has significantly increased.

    ===================================

    Client about the collaboration:
    "I recommend Sergey as an excellent specialist and expert! Completed ahead of schedule! Quality work and great communication! 10 out of 10."

    Acceleration of the website on Khoroshop (PageSpeed Mobile 95) — example of freelancer's portfolio work in category Online Stores & E-commerce
    The client contacted with a problem of slow page loading on mobile devices. After a technical audit, I discovered blocking scripts, heavy styles, and incorrect template elements. I optimized the loading order of resources, configured Lazy Load, removed unnecessary calls in the header, and simplified the rendering of critical blocks.

    After optimization, the site received a PageSpeed Mobile score of 95, LCP decreased to 2.4 seconds, FCP to 1.8 seconds, Total Blocking Time to 80 ms, and the CLS score is 0.

    … Result: the mobile version became noticeably faster, navigation responds instantly, and performance metrics moved into a stable green zone.

    ============================================

    Client feedback:
    "Everything is clear and of high quality, professional work!" — rating 5/5 for all parameters.

    Free Shipping Bar for Mobile Cart — integration for Khoroshop

    Online Stores & E-commerce
    Free Shipping Bar for Mobile Cart — integration for Khoroshop — example of freelancer's portfolio work in category Online Stores & E-commerce
    ## Task:

    Implement an adaptive free shipping indicator on the Horoshop platform for the mobile version of the cart.
    The key condition is full compatibility with the internal logic of the site (mmenu, overlays, dynamic content loading) without interfering with the core.
    …
    ## Main Goals

    = Add the bar only when there are products in the cart
    = Automatically update the amount "remaining for free shipping" when the order changes
    = Completely hide the bar when the cart is empty
    = Display the festive message "Free shipping available!"
    = Hide the line "Remaining 0 UAH" when the limit is reached
    = Ensure correct operation on all mobile devices without visual glitches

    ## Technical Implementation

    Language:
    pure JavaScript (Vanilla) without third-party libraries
    Observers:
    MutationObserver was used to track changes in the DOM (.j-cart-product, .j-total-sum)
    Conditional Logic:
    - the bar is not inserted into an empty cart;
    - automatically added when the first product appears;
    - removed when the last one is deleted;
    - smooth width update of the indicator through transition.

    ## Styling:

    embedded with dynamic connection for full autonomy.
    Compatibility:
    tested in Safari, Chrome, Firefox on iOS / Android
    UX Logic:
    no forced closing of the cart or interference with mm-opening / overflow:hidden.

    ## Result

    A neat, lightweight, and reactive module was obtained that:
    = works independently of the store layout;
    = smoothly updates the state without reloading the page;
    = gives the user a sense of "movement towards the goal" (gamification of the purchase).

    ## Visual Highlights

    Delivery icon from png image /content/uploads/images/free_shippling.png
    Neat progress line with brand color #21a67a
    Mobile block styled in the Horoshop brand style

    ## From the Author

    The project is an example of how even a simple indicator can become a living, intelligent element of UX.
    It was important for me not just to "draw a scale," but to integrate it into the ecosystem of the site so that the user felt the smoothness and logic — as if all of this is part of the core of the platform.

    Before → After: refinement and acceleration of the online store

    Before → After: refinement and acceleration of the online store — example of freelancer's portfolio work in category
    The project came to me after several previous developers, and the store was in critical condition: slow performance, numerous errors, instability, cart failures, issues with the product card, and conflicting modules.

    * cart and checkout freezes
    * layout breaks on mobile
    * duplicate scripts
    * heavy images
    * lack of caching
    * unstructured code
    * lagging interface

    As a result, the store was losing customers, and the website owner was losing money.

    == What was done (After):
    1. Technical audit and code cleanup

    - identified and resolved module conflicts
    - removed unnecessary duplicate scripts
    - optimized template structure
    - fixed logic errors in the cart and checkout

    - fixed product card display
    - adjusted filters
    - reworked incorrect buttons/blocks
    - improved logic for tab transitions

    4. Increased stability

    - cleared errors in logs
    - updated and configured modules
    - reduced the number of requests
    - eliminated bugs that caused freezes

    == Result (After)

    The website started working:

    - faster
    - more stable
    - neater
    - clearer for the user
    - safer for the owner

    The client gained the ability to further develop the project without fearing that something would "crash."

The work was done excellently. The module for OpenCart 3.0 fully meets the standards of commercial development, and in some aspects even exceeds the requirements of the technical specifications. The programmer took care of security, implemented additional protection mechanisms, and approached all technical details very responsibly. All corrections were made quickly, communication was at a high level. I definitely recommend for collaboration!
