Need to add a couple of functions to the current project on Express.js/React.

Budget: 1000 UAH Deadline: 1 day

Good day.

Regarding the task, it is clear that you already have a working communication through the ChatGPT API. It is necessary to carefully expand the functionality through tools and tidy up part of the logic and interface in React. I can quickly understand the current implementation, add the necessary functions to the API layer, correctly link them with the front end, and make adjustments without breaking the existing flow.

I have worked with the ChatGPT API and tools, and I understand the nuances of context, function calls, and response handling on the backend side. I can easily make changes to the current web in the React part so that everything looks and works stably. If needed, I can suggest a more convenient structure for interaction between the front end and the server for further scaling.

If the project goes further, it makes sense to establish a foundation for long-term cooperation. I suggest discussing the details regarding timelines and costs in private messages.

Hello!

I am ready to help with the implementation of Tools (Function calling) in your project. I have a great understanding of how this mechanism works in the OpenAI API: from the description of JSON schemas for functions to processing tool_calls on the backend and returning the result back to the dialogue context.

What I will do:
I will add the necessary functions to the API request (search, working with the database or external APIs — depending on what is required).
I will set up the correct handling of model responses.
I will quickly make adjustments in React (layout, state, display logic).

Since I am looking for long-term collaboration, I will do everything cleanly and promptly to demonstrate the level of work. I am ready to start today.

What is your backend stack (Node.js/Python)? Expand

Hello.
I understand the task well: you already have a working chat flow based on ChatGPT, and the goal is to expand it using tools/function calls and clean up the React side without disrupting the existing logic. I can quickly integrate the ChatGPT API tools, structure the backend so that new features can be easily added, and make changes to the frontend clear and predictable. I usually work carefully on live products, improving what exists rather than rewriting everything from scratch. I would be happy to start with these tasks and grow them into a long-term collaboration if it works out.

Hi!
I’d be happy to help with this project.

I have solid experience working with the ChatGPT API, including message pipelines, tool/function calling, context management, and response handling. I can extend your existing implementation by adding new API features (based on ChatGPT tools) while keeping the current logic stable and clean.

On the frontend side, I’m comfortable working with React to adjust UI behavior, improve message flow, and ensure smooth interaction between the client and backend. I’m used to working on existing codebases rather than rebuilding from scratch, so incremental improvements and clean integrations are not a problem.

How I’d approach this:

Review the current backend ChatGPT integration and API flow

Implement the required new features using ChatGPT tools/functions

Refine request/response handling and error states

Make the necessary React adjustments for UX and data flow

Test end-to-end to ensure stability

I’m open to long-term collaboration and ongoing feature development if this project moves forward.

Let me know more about your current stack and the specific features you want to add, and I can give you a clear estimate for time and cost. Expand

Hello, I can do it quickly in 1-2 days. I also write agents with OpenAI/gemini. There is a website generator with various tools. I also use other types of tools like tts, stt, embedding. I have a lot of experience - write to me.

Hello! I have worked with the OpenAI API. I understand what you mean: you need to implement Function Calling (Tools) so that the model can not just chat, but perform actions or request data from the backend. This is feasible.

Regarding the front end (React) — this is my main stack. I can quickly fix the layout and component logic.

I am ready to take on the task as a test to start, and if we work well together — I am interested in long-term collaboration. I can start today.
