Description: I am looking for a developer to build a mini chatbot using a popular chatbot API (OpenAI, Google Dialogflow, or similar). The chatbot should be lightweight, responsive, and easily deployable on web or mobile. Responsibilities: Integrate chatbot API into a simple frontend (web or mobile). Set up backend service for handling API requests and session management. Implement a clean, user-friendly chat UI. (Optional) Store chat history in a database. Deploy to cloud hosting. Requirements: Experience with JavaScript/TypeScript (Node.js, React/[login to view URL]) OR Python (FastAPI/Flask). Familiarity with chatbot APIs like OpenAI GPT / Dialogflow / Rasa / Microsoft Bot Framework. Knowledge of basic database integration (MongoDB, PostgreSQL). Strong UI/UX sense for chat interface. Nice to Have: Experience deploying on Vercel, AWS, or GCP. Prior chatbot project examples. Acceptance is straightforward: the bot answers our predefined FAQ set with at least 90 % accuracy in testing, escalates on command, and passes App Store / Play Store review with no crashes or API key leaks. If you have recent experience wiring OpenAI or Dialogflow into mobile apps and can get an MVP up quickly, let’s talk.

Hi Ervin, We recently developed a mobile app called “Descripio” that uses OpenAI’s API to generate product descriptions from Amazon URLs. We built a fully responsive web app with a clean UI and integrated Google login for user authentication. We also implemented a cron job to fetch product data daily, ensuring users always have the latest information. We can use a similar approach for your project, where we create a lightweight web app that serves as a front-end for the chatbot. This way, we can focus on building a robust back-end that handles multiple front-end integrations, whether it’s a web app, mobile app, or browser extension. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit for your needs. Best, Adil
