Full-stack development — Amazon PPC Dashboard (Stage 1)

Good day. The task is close to the stack: Python/FastAPI, SQL, Linux, API integrations, frontend on React/TS, I can complete it as working Stage 1.

I will do it step by step: I will apply migrations and health check for the database, connect the pool, assemble the sync page, synchronize Amazon Ads/SP API with logs/UPSERT, perform basic data validation, and deploy on the server. Access to the repository, server, MariaDB, and Amazon credentials is needed.

I set the deadline for 8 days to leave time for testing on live profiles and fixing edge cases.

Hello!

I can connect and fully implement the first stage using React, FastAPI, MariaDB, and scheduled synchronization tasks. I have experience working with both the Amazon Ads API and the SP API in real projects, including configurations with multiple marketplaces. For the dashboard, I would make the backend as simple and predictable as possible by using a single synchronization mechanism that logs each task into a common operations table. This way, the `/sync` page can poll one simple endpoint and always display the current progress, errors, and the last 20 runs without unnecessary logic and guesswork.

There is another idea that will simplify project maintenance in the long term: adding a small block with synchronization status that updates after each run. For example, storing `last_success_at`, `last_error`, `rows_upserted`, and `api_rate_limit_hits` for each profile and marketplace. Then, when a problem arises, you will immediately see what exactly broke and where, without the need to sift through logs.

… As for AI tools, I use Cursor and GitHub Copilot daily, and I also apply Claude Code for quick refactorings, creating test templates, and checking edge cases.

The most challenging part of the project is synchronizing Amazon Ads reports, as report generation works asynchronously. Here, careful implementation of report readiness waiting, API rate limit handling, retries, and partial errors is required for five profiles while maintaining data consistency in the database with safe UPSERT logic.

Budget and timeline: fixed cost — $1000 for all 7 tasks, completion time — 7 days.

Thank you!

❤️Hi Sergej, hope you are doing well

I can help apply the 32-table migrations, connect MariaDB pooling, build the /sync page, implement ads_sync.py and sp_sync.py with OAuth/LWA, UPSERT logic, marketplace/profile sync, polling status, logs, and scheduled jobs. I also use AI tools like Cursor, GitHub Copilot, and Claude-style workflows to speed up development while keeping code reviewed.

The hardest task is Amazon Ads/SP API sync because rate limits, report generation delays, marketplace/profile mapping, and UPSERT consistency must be handled carefully.

I can provide an accurate timeline after reviewing the DOCX spec.

Best regards,
… Youssef.

I have been working with React 18 + TypeScript + Vite + Tailwind in daily projects for 3.5 years. Prototyping the frontend on your stack (React + TypeScript + Tailwind) is exactly what I do constantly. I have been involved in integrating various external APIs, building dashboards with real-time data updates, and complex state management. I studied the Amazon Advertising API through the documentation - the structure of OAuth2 LWA and UPSERT patterns for synchronizing advertising data are clear to me.

Regarding the backend: my main stack is NestJS/Node.js, however, I am well acquainted with FastAPI/Python in terms of architecture (similar principles to Express/NestJS). APScheduler for cron jobs, connection pooling with MariaDB, and the UPSERT pattern - these are all standard tasks I have worked on. I implemented CSV parsing with auto-detection of types based on headers for B2B e-commerce projects.

I use AI tools every day: Claude Code as my main assistant for code review and architectural decisions. The most challenging task out of 7 - synchronizing the Amazon Ads API (task 4): it is necessary to correctly handle rate limits, retry logic, and ensure the idempotency of UPSERT during daily runs. I am ready to discuss the details and show my approach to implementation.

Good day!

To better understand the situation, please clarify:
1. Are there any time constraints for completing each task within 7 days?
2. What volume of data is expected when synchronizing with the Amazon API?
3. Is support required after the project is completed?

Approach to task execution:
1. I will use my previous experience with the Amazon Ads API to ensure correct integration and data synchronization.
… 2. I actively use AI tools like GitHub Copilot and Claude Code, which helps speed up the development process and minimize errors.
3. The use of the UPSERT pattern in database work ensures data stability and integrity during synchronization.

The fixed price for completing all 7 tasks will depend on the volume of data and additional requirements. I am ready to discuss this after clarifying the details.

Complexity:
The most challenging task may be the synchronization of the Amazon Advertising API and SP API, considering the need for proper handling of large volumes of data and timely updates.

Examples of projects with Amazon API:
1. A dashboard for analyzing advertising campaigns based on the Amazon Ads API.
2. An inventory management system using the Amazon SP API.

Please let me know if there are any additional questions or if clarification on the project is needed.

Hello. I read the technical specifications: Stage 1 of the internal PPC dashboard, where the front end is already in React and TypeScript, the backend is in FastAPI in basic structure, and we need to complete seven tasks within a week, from the overall layout and synchronization page to daily syncs with the Amazon Ads API and SP API, CSV uploads, and automatic Stock Feed uploads with campaign pause logic based on inventory levels.

The stack is exactly my expertise: FastAPI on Python 3.11, APScheduler for daily tasks at 03:00, 05:00, and 06:00, connection pooling to MariaDB, UPSERT pattern for synchronizing profiles, campaigns, keywords, and reports. For the Amazon Ads API, I would create ads_sync.py with six types of reports through their asynchronous flow: report request, readiness polling, downloading, and parsing. For the SP API, similarly, sp_sync.py for five marketplaces with catalog, FBA inventory, Buy Box, and orders. I will build the sync page with four sections, drag-and-drop upload, and progress tracking through polling every two seconds, as specified in the technical specifications. The CSV parser will automatically determine the report type based on headers, and the Stock Feed will follow a schedule with the rule that qty 0 pauses and qty from 4 resumes.

I constantly work with FastAPI, async, external API integrations, and schedulers; I created a notification hub on FastAPI with webhooks and deep logging. In my daily work, I use Claude Code and Cursor. I am ready to accept the full technical specifications in DOCX and start with the application of three migrations and a health endpoint, then proceed with the task list.

Please clarify: have the accesses to Amazon Ads and SP API already been issued under the production account, or do they still need to go through the application approval process with Amazon?

To implement Stage 1 of your PPC dashboard, I will set up data collection from the Amazon Ads API and SP API for the 5 specified European marketplaces. I will ensure the deployment of a connection pool in FastAPI to work with 32 MariaDB tables and seamless synchronization of campaigns and inventory on a schedule via APScheduler.
I have practical experience integrating with Amazon Ads and SP API using the UPSERT pattern to update advertising campaigns and product stock. To give you an idea, the logic for updating data in ads_sync.py will look something like this:
for campaign in campaigns:
db.execute("INSERT INTO amzppccampaigns (id, name, status) VALUES (:id, :name, :status) ON DUPLICATE KEY UPDATE name = VALUES(name), status = VALUES(status)", campaign)
This will eliminate record duplication during the daily synchronization run at 03:00.
I am waiting for the technical specification in DOCX format for detailed review and am ready to start work immediately after setting up access on your VPS.

Hello,

Your project immediately caught my attention because it combines exactly the areas I specialize in: scalable full-stack systems, Amazon Ads/SP API integrations, FastAPI backends, React dashboards, and AI-assisted development workflows.

I have hands-on experience working with Amazon APIs, including:

* Amazon Advertising API
* Amazon SP API
* OAuth2 / LWA authorization
… * scheduled synchronization services
* marketplace multi-region handling
* reporting pipelines
* UPSERT-based data synchronization
* inventory and PPC automation systems

I’ve also built internal dashboards and data-heavy systems using:

* React + TypeScript
* FastAPI (Python)
* MariaDB / MySQL
* APScheduler
* Cloudflare deployments
* REST + async processing architectures

Your architecture and task structure are very clear and professionally organized, which is exactly the kind of environment I prefer working in.

Regarding AI-assisted development:
I actively use AI tools daily, including:

* Claude Code
* Cursor
* GitHub Copilot
* ChatGPT
* AI-assisted debugging and architecture planning workflows

These tools significantly improve development speed, code quality, testing workflows, and documentation consistency—especially under tight deadlines like your 7-day delivery target.

The most difficult task in this project is likely:

Task #4 — Amazon Advertising API synchronization.

Reason:
Amazon Ads reporting pipelines involve:

* asynchronous report generation
* rate limiting
* delayed report availability
* marketplace-specific inconsistencies
* large data synchronization
* incremental UPSERT handling
* retry/error recovery logic

Additionally, maintaining reliable synchronization across multiple marketplaces while preserving data consistency in MariaDB requires careful architecture from the beginning.

That said, this is also the type of backend/data engineering challenge I’m comfortable handling.

I can work independently, communicate clearly, and move quickly without sacrificing architecture quality or maintainability.

Estimated fixed price for all 7 tasks:
$2,000 – $2,500 USD
(depending on final specification details and production hardening requirements)

I’d be happy to review the DOCX specifications and discuss implementation details further.

Looking forward to hearing from you.

I am a NextJs, React, NestJs developer. I am ready to take on this task.
