640 USD Integration of OpenCart with KeyCRM and automation of the online store
Client Management & CRM
Online store on OpenCart 3.0 with a catalog of 5814 products.
The business decided to implement KeyCRM to:
… centralize order processing
automate logistics
connect fiscalization
obtain proper sales analytics
Problem
Before integration, the processes were chaotic.
Orders were processed only through the OpenCart admin panel.
CRM was not used.
Logistics were created manually.
The catalog was not prepared for synchronization.
SKUs had conflicts.
During the installation of the integration module, a critical problem occurred — the checkout stopped working.
This meant a loss of sales right during the integration.
Task
It was necessary to:
• integrate OpenCart → KeyCRM
• prepare the catalog for CRM
• set up logistics
• connect fiscalization
• automate order processing
Solution Architecture
A system was built:
OpenCart → KeyCRM → Nova Poshta / Ukrposhta → Checkbox
OpenCart
— website and product catalog
KeyCRM
— order management
— statuses
— analytics
Nova Poshta / Ukrposhta
— creation of shipping documents
Checkbox
— fiscalization of orders
What was done
1. Catalog Preparation
An audit of products was conducted.
SKU conflicts were resolved.
Import for CRM was prepared.
Imported:
5814 products into KeyCRM
2. CRM Integration
Order transfer from the website to CRM was set up.
Mapping was done for:
payments
delivery methods
Order transfer was tested with test purchases.
3. Logistics
Connected:
Nova Poshta
Ukrposhta
Set up the creation of shipping documents directly from CRM.
4. Fiscalization
Checkbox was connected.
Automatic fiscalization of orders was set up.
5. Diagnosis of Critical Error
After installing the integration module, the checkout stopped working.
The problem was due to a conflict of OpenCart modules.
The error caused a 500 error in checkout.
The conflict was found and resolved.
The website returned to normal operation.
Result
The store received:
- a centralized order system
- automated logistics
- fiscalization through CRM
- a prepared catalog for synchronization
- automated order processing workflows

400 USD Automated Security Data Analysis for Kubernetes
AI & Machine Learning
#Kubernetes #Security #Automation #GPT #DataAnalysis #DevSecOps #AI #PromptEngineering #BigData
This project aims to automate the analysis of large Kubernetes security JSON reports (#Polaris, #Trivy, #Kubescape). The client needed a user-friendly tool to transform raw data into a useful report with key findings, best practices, recommendations, and a maturity assessment. The result was to be presentation-ready for both technical and non-technical audiences.
… Tasks and Challenges
• Processing huge volumes of data (#BigData) without exceeding the GPT context.
• Separate #Prompts for each tool to enhance accuracy (#PromptEngineering).
• Balancing costs: the initial level of summarization should be cheaper (#gpt-3.5-turbo), the final one deeper (#o1-mini), to maintain quality (#CostOptimization).
• Hierarchical approach (#HierarchicalAnalysis) and caching (#Caching) to speed up reruns.
Solutions
1. Hierarchical analysis: Data is broken into chunks, summarized by gpt-3.5-turbo, then the summaries of the three tools are combined by o1-mini.
2. Separate prompts: Each tool has its own prompt tailored to the data format (#Polaris, #Trivy, #Kubescape).
3. Caching: Reduces time and cost of reruns.
4. Modularity: The code is divided into modules, simplifying future updates (#Modularity).
Results
• Full automation of analysis (#Automation): Huge files are processed without manual labor.
• Cost optimization (#CostEffective): Initial summaries by gpt-3.5-turbo are cheap, caching is fast.
• Quality final report (#QualityOutput): Thanks to the hybrid approach and prompts, the report is accurate, relevant, and presentation-ready.
Conclusion
This case demonstrates the effectiveness of #AI, #LLM, and #PromptEngineering in #DevSecOps and #DataAnalysis tasks. The combination of different models, hierarchical analysis, modular architecture, and clear documentation made the solution flexible, scalable, and cost-effective.
