Hello. I can develop an API using Node.js and Nest.js. The client purchases a certain number of keywords, that is, a list of prompts that the AI model works with. Each pricing plan can include several prompts or the client can buy as many as needed for different tasks. Payment is hourly; I work as a sole proprietor. Please contact me to discuss the details.

Hello, Emin!

Creating intelligent recommendation logic requires both technical expertise and a creative approach. I will focus on developing a flexible AI model that adapts to changes in rates, and an efficient API that ensures seamless backend operation. My experience in integrating complex AI systems and developing capabilities in Node.js and Python will provide a reliable and scalable solution that meets your business requirements. I am ready to discuss the details and offer adaptive innovative ideas for your project.

Good day!

I am a backend developer and AI engineer with over 16 years of experience (PHP, Python, Node.js, integration with GPT/LLM). I understand that you need not just a model call, but a full-fledged tariff engine: a rule base (segments, conditions, priorities, exceptions) + simple AI models/classifiers + prompt logic, combined into one service with an API.

I propose that in the first stage we define the business rules and scenarios together, then implement the core of the tariff engine and the AI part, and provide a clean REST API for integration with your product. I have worked with high-load projects and recommendation/rule systems, so I can offer an architecture with room for scaling.

I am ready to discuss the details of the domain and the choice of stack (Python / Node.js / PHP) and agree on the implementation stages.

Hello Emin, I am a Python developer with over 7 years of experience, and I also have experience integrating AI into business processes. For the backend, I propose Python + Django. However, I have questions about AI, but it looks very interesting; I suggest we discuss the details.

I would be happy to collaborate.

Dear client!
I specialize in artificial intelligence logic systems and backend development. I will create a rule base for you, develop small artificial intelligence models, implement hint logic, and create a classifier for accurate rate recommendations. On the backend, I will write an API, integrate the models, and structure the project using Node.js/Python for maximum scalability.
I am confident that I can provide a quality solution.
I look forward to your response.

I understood the task — here we need not just to "connect a model," but to build the logic of recommendations based on rules + AI classification, and to assemble all this into a working backend with an API.

Technically, it seems feasible.

I can cover both parts:
— AI logic (classifiers, prompts, rules, lightweight model for a specific business context)
— backend (API, integrations, architecture, storage of rules/data, connection of models).

Technologies — Node.js or Python are the best fit, but if your current stack is PHP — I can adapt as well.
…
My work: https://dima.ge

To move forward, I would like to clarify a couple of points:

Do you already have data/rates and case examples, or do we need to design the logic from scratch?

Are you planning to use third-party models (OpenAI, DeepSeek, Claude) or do you need a local option?

Will the system be used within the product or as a separate standalone service with an API?

Once you respond, I will be able to propose an architecture and a range of timelines.

Hi, Thanks for your job posting.
I am really confident in my skills to do your project perfectly.
I have 8 years of experience in Node.js, Python.
And also I can implement the whole logic fully!!!
I think I can complete all things you want from me.
Let's discuss the project.
Thanks.

I will create a tariff recommender that combines rules, simple ML models, and AI logic.
Technologies
Core: Python
Backend: FastAPI / Django (we will discuss which is better for your tasks)
Storage: PostgreSQL / MySQL, Redis if necessary.
AI/ML: scikit-learn / simple models + integration with LLM via API.

Hello!

I am creating backend systems that connect intelligent models with real APIs, and I can implement a clear tariff recommendation mechanism into your stack. I have experience combining lightweight machine learning models, logic driven by prompts, and reliable Node.js and Python services, which allows recommendations to be delivered quickly and be auditable.

I plan to create a rules layer, a simple classifier, and a small ensemble of models, and then wrap them in clear REST endpoints and a well-defined project structure so that other engineers can expand them.

One idea I propose is a real-time tariff simulator that provides a brief, clear explanation of each recommendation and the projected impact on cost, so that clients can trust this offering.

I can provide a working prototype in 14 days with integration and testing for $2,200 and a production-ready version in 35 days for $4,200 (subsequent support and adjustments).

Hello.
Your project aims to build an intelligent tariff-recommendation engine, and I can help by combining strong backend architecture with practical AI logic. I would design a clear rule-based foundation, integrate lightweight ML models, and create a reliable classifier that delivers consistent and explainable recommendations. On the backend side, I will structure the project cleanly, develop stable APIs, and seamlessly connect all AI components into a single decision pipeline. With experience in Node.js, Python, and AI-driven systems, I can deliver a scalable, maintainable solution that’s easy to evolve as your tariff engine grows.

Hello!
My name is Semen, I am the manager of the company Wanord. We specialize in developing AI logic, recommendation systems, and backend services (Node.js / Python / PHP) for products with pricing grids and complex rules.

📌 What is needed:
To build and implement a "smart" pricing engine that combines a rule base, simple AI models, prompt logic, user/situation classification, and a backend API for integration with your product. We need a specialist who understands AI/ML and can build a reliable backend. The logic of the task is clear.

🔧 What we will do:

AI part / pricing engine
…
We will design and implement a flexible rule base (segments, conditions, priorities, exceptions).

We will create simple AI models/classifiers that will help choose the best tariff (based on behavior, history, client parameters).

We will set up prompt logic (if LLM/AI services are used) to explain recommendations or hints to managers/users.

We will gather everything into a single pricing engine: rules + models + configurations, so that it can be managed through code/config.

Backend part

We will design the project structure (layers: data → business logic → API).

We will write a REST API for:
• obtaining tariff recommendations;
• testing different scenarios;
• administering rules/models (if needed).

We will integrate AI models (Node.js or Python as the base, with the ability to interact with external services).

We will ensure logging, decision monitoring, and the ability for A/B testing of different recommendation strategies.

Integration and documentation

We will prepare technical documentation for the API and the structure of the pricing engine.

We will help integrate this with your existing product/CRM/dashboard.

If needed, we will add simple analytical reports (which tariffs are recommended/selected, conversion, errors).

💼 We have experience:
AI models for business logic, recommendation systems, prompt engineering, backend API development in Node.js and Python, building pricing/legal engines, integration with existing products.

💰 Budget: from $3000 to $6000 (fixed price with payment by stages)
⏱️ Timeline: 4–6 weeks, in stages: logic design → AI + rules → backend + API → testing and integration.

We are ready to take on and adapt the solution to your subject area — write to us in private messages, we will discuss the details, technology stack (Node.js / Python), and finalize the stages of work for your project.
