PDF certificate database on WordPress
112 USD 
The price is 5000 UAH conditionally. Please write your price proposal immediately.
The technical task (attached below as a docx file) is ready at 90-99%, as the final version will be agreed upon with the person who will implement it.
In the technical task, in the section "Non-functional requirements," it is stated "Code is documented." This means that, for example, a year later I can open the code and understand what is happening here in 15-20 minutes.
"The code must contain clear comments in places of business logic implementation, SQL structures, data import, and PDF access mechanisms. Comments should explain the reason for implementation, not duplicate the syntax of the code."
Along with this, I do not require the following:
* separate complete technical documentation
* commenting on every line
* diagram-based documentation
* fancy dev-docs
Regarding design and visuals, I am open to suggestions.
+ If you have a counter proposal for the implementation of this project - I am open to dialogues.

Hello!
The technical specification is professionally composed. I see the main requirement: no CPT/ACF and no unnecessary load, only pure SQL. This is the only correct solution for a database with 50k+ records to ensure instant search.
Technical implementation:
Backend: I will write a separate lightweight plugin. Working with the database through $wpdb->prepare (full protection against injections).
File security: I will implement a secure mechanism for delivering PDF via PHP stream (the file is physically inaccessible via direct link, session check before download).
Frontend: AJAX search without page reload.
Import: I will write a fast CSV importer that will handle large data arrays (chunking) without server timeouts.
… The code will be documented (PHPDoc) and ready for scaling.
Conditions:
Budget: $400-600.
Ready to start.

Good day, my name is Dmytro, I represent the KingKongLab team. I have reviewed the technical task — it is well thought out, the logic is clear, and the approach to architecture and code quality requirements is completely adequate.
We have experience in implementing custom solutions on WordPress with our own SQL layer, without unnecessary plugins, CPT, and ACF. We can implement a closed certificate system according to the technical specifications: custom authorization, AJAX search by lot number, variety name, and year, secure PDF upload through a controller, as well as a minimal admin panel with CSV import and manual record management.
I would like to highlight the requirement for documented code — this is a clear and correct request. The code will be structured, with comments specifically in the places of business logic, SQL queries, data import, and the mechanism for accessing PDFs, with explanations of solutions rather than duplicating syntax. Without unnecessary "documentation for the sake of documentation," but in such a way that a year later one can quickly understand the code.
Regarding security, we will implement nonce, capability checks, closed URLs, direct access to PDFs will be blocked, and queries will be through wpdb->prepare. The architecture will be designed with a margin for scaling up to 50k+ records.
As for design and visuals — we can offer a simple, understandable solution or discuss alternative approaches. We are also open to dialogue if you have counter ideas or want to optimize the implementation.
…
I am ready to go through the technical specifications in detail, clarify the final 1–10% of details, and after that, provide a clear estimate of timelines and costs.
