4B Systems Software House implementations in Python

Knowledge base for law firm employees


The law firm needed a system that would provide quick access to legal expertise, making it easier for employees to find answers to complex legal inquiries.


We used Python and OpenAI GPT-3 technology to create a knowledge base that can generate precise answers to questions in various legal fields through the use of artificial intelligence. The system has been enriched with the function of learning from each query, so that its efficiency increases with use.

The result

The platform allows employees to save time and increase work efficiency by providing quick access to the information they need. The implemented solution has improved the decision-making process and increased the company’s overall productivity.

Chatbot for e-commerce


Our goal was to create an advanced chatbot for a direct sales platform that could automatically respond to customer inquiries, recommend products and help navigate the site.


Using Python and GPT-4’s OpenAI API, the team developed an intelligent chatbot that understands customer queries in natural language through advanced natural language processing (NLP). The chatbot has been programmed to learn from each interaction, allowing it to continuously improve its responses and product recommendations.

The result

By integrating with the product database and customer interaction history, the chatbot offers personalized suggestions, improving the user experience and increasing conversions on the site.

System for processing consumer coupons based on sales data


Fast Moving Consumer Goods (FMCG) companies have been challenged by the lack of an integrated platform to efficiently process sales data, issue coupons that give purchase discounts to retailers, and communicate with retailers. The lack of such a solution limited opportunities to optimize sales and made it difficult to manage promotions.


We designed and implemented a comprehensive system that integrates sales data processing with a coupon issuing mechanism and a communication platform for retailers. Using machine learning techniques, the system was able to analyze historical sales data, identify trends and automatically generate coupon proposals that most closely matched current market needs and retailers’ shopping preferences. In addition, the platform enabled direct communication between producers and traders, which allowed quick exchange of information and adjustment of promotional offers.

The result

Manufacturers gained a tool to effectively manage promotions, which allowed them to dynamically adjust offers based on current sales data and market trends. Retailers have been enabled by the system to receive personalized coupons, which has contributed to their interest in promotions and increased orders. FMCG companies were able to plan their promotional campaigns more deliberately, resulting in higher efficiency in marketing and sales activities.

Property price prediction application for compensation company

Using real estate market datasets, the team developed an application to predict property prices based on various parameters, such as location, area, standard of finish and others. The machine learning model was trained on historical transaction data, allowing it to accurately predict listing prices for different types of properties. The application was a valuable tool for real estate agents, investors and those looking for apartments or houses.

Data management system for E-commerce using numpy and pandas

The project involved the development of an advanced product data management system for an e-commerce platform. Using Numpy and Pandas libraries, the team developed an efficient way to process, analyze and aggregate product data from various sources. The system allowed automatic data cleaning, consistency verification and generation of detailed reports, which significantly improved assortment management and inventory planning.

Product recommendation system

The project consisted of developing a product recommendation system for an online shopping platform. The team used machine learning techniques to analyze purchase history, user preferences and product ratings to make personalized recommendations. This system allowed not only to increase customer satisfaction by providing more relevant proposals, but also to optimize sales by promoting products with high interest potential.

Python development. Questions and answers

Why choose Python for application development?

Python is a versatile programming language that features simple syntax and readable code, making it easy to develop projects quickly. It is an excellent choice for both beginners and experienced programmers. Python supports a variety of programming paradigms, including object-oriented, imperative and functional, which makes it flexible for use with different types of projects – from web applications, to data analysis, to artificial intelligence, to automation and more.

What types of applications can be developed in Python?

Python is used to develop a wide range of applications, including:

  • Web applications (thanks to frameworks like Django and Flask)
  • Desktop applications (e.g., using PyQt, Tkinter)
  • Machine learning and artificial intelligence solutions
  • Automation scripts and data analysis tools
  • Web applications and backend services
  • Cloud solutions and DevOps

Is Python appropriate for my project?

Python is a very flexible language that works well for many types of projects. Its versatility makes it a good choice for projects requiring rapid prototyping, complex data analysis, web applications, and more. However, the choice of technology should always be made on a case-by-case basis, depending on the specific requirements of the project, such as performance, scalability or specific technology dependencies.

Do you provide support after project implementation?

Yes, we offer comprehensive post-implementation support for the project, which includes both ongoing maintenance of the system and the possibility of further development. As a result, our customers can be sure that their application will not only function stably, but also develop in accordance with the growing demands of the market.

What are the expected costs of implementing the project in Python?

The cost of a project depends on a number of factors, such as the scope of the work, the complexity of the project, the technologies chosen and the lead time. We prepare a customized quote for each project that best reflects its requirements and goals. Feel free to contact us for more information and an initial consultation.

How do you ensure code quality in Python projects?
