Good day. It's not a problem to do this, but I would still like to first take a look at the table and the JSON. You can review my work experience in the feedback history.
Looking forward to working with you!

Hello! 👋
I have experience in developing systems for processing large volumes of data (millions of records), including CSV import, working with JSON, optimizing MySQL, and automatically updating data on a schedule. I will be able to implement a stable process for processing your file with the assortment and photos.
Here’s how I will implement it:
importing the original CSV (200k records) into a MySQL table while preserving the structure + update date field;
processing JSON from the link and extracting URLs of all photos;
writing photos into a separate table (up to 4 million records) linked to the product;
optimizing the database structure (indexes, batch inserts, chunk processing);
automatically updating data 5 times a day via cron;
a logging system, import correctness checks, and error control;
optimizing the speed of processing large volumes of data.
I have worked on tasks that require processing millions of records and large data arrays, so I pay special attention to the performance and stability of the process.
I am ready to discuss the details of the CSV and JSON structure, after which I will be able to estimate the timeline and budget.

Hello. I have experience with parsing csv and json. I am ready to create a structured database, but first I would like to see the structure of the csv. I can also provide a script if information will be added to the csv with this structure.

Hello! 🚀
I have experience working with large volumes of data: importing CSV files with hundreds of thousands of records, processing JSON via links, loading millions of rows into MySQL, building stable ETL/parsing pipelines with scheduled updates, logging, retry mechanisms, and data integrity checks. For your task, I can implement a fast loading system for the assortment, extracting photos into a separate table, updating 5 times a day.
The stack I will be using:
Backend: Python, MySQL, asyncio / aiohttp, multiprocessing
Integrations: CSV import pipeline, JSON parsing, cron / scheduler, logging, retry / monitoring
Infrastructure: Docker, VPS / server, Redis (if needed), CI/CD
I am ready to discuss the project details in person and am ready to start working.
Best regards, Andriy!

Good day, Dmytro!
We have experience working with large datasets — parsing Google Maps with over 200K entries, processing JSON responses, loading into PostgreSQL with deduplication and incremental updates.
Regarding your task:
1. Import CSV (200K rows, 10+ columns) into MySQL with indexes for fast searching + an update date column
2. Parse JSON from links → a separate photo table (2-4 million entries) with a foreign key to the main table
3. Automatic updates 5 times a day on schedule (cron) with logging and integrity checks
For fast processing of millions of entries, we use batch-insert (LOAD DATA / bulk insert), parallel processing of JSON, and process monitoring.
We are ready to show an example of our approach after reviewing the CSV and JSON. We propose working through Safe.

Hello! I have been engaged in data parsing for over 3 years. I implemented a similar project, but instead of images, we worked with archives.
I will be able to implement everything quickly and efficiently! As soon as we discuss the details - I will start working.
