You will get secure AI Backend API (OpenAI, Claude) built with Python FastAPI
Top Rated

Project details
Stop exposing your OpenAI API Keys in your frontend code! Get a secure, production-ready AI Backend built with Python FastAPI.
Connecting your mobile app or website directly to ChatGPT/Claude is a huge security risk. I build a robust Middle-Ware API that acts as a secure bridge between your users and AI models.
Why choose this architecture?
š Bank-Grade Security: Your API keys stay hidden on the server. I implement API Key authentication or JWT to control who accesses your bot.
ā” High Performance: Built with Python FastAPI, the fastest modern web framework, ensuring low latency for your users.
š Multi-Model Support: I use advanced libraries (LiteLLM) that allow you to switch between GPT-4, Claude 3.5, or Gemini Pro with a single line of config. You are not locked into one provider.
š³ Dockerized Delivery: I deliver the entire backend in a Docker container. You can run it on AWS, DigitalOcean, or Azure without "it works on my machine" issues.
š Chat History (Advanced Tier): I connect a database (PostgreSQL/MongoDB) to store conversation history, giving your AI "long-term memory."
Perfect for SaaS founders, Mobile App Developers, and Enterprise internal tools.

Scrape names and addresses of vet practices from websites
Enis is a true professional. He got to work almost immediately and understood my needs completely. He delivered my first set of milestones within a day and went above and beyond. He made suggestions to improve the scope of work and beyond scraping designed a whole new searchable map interface for me in Leaflet. I was so impressed I added a few more milestones and look forward to working with him again in the future. Very highly recommended!

About Enis
Senior Python Developer | Backend APIs, Automation & Data Extraction
100%
Job Success
Istanbul, TurkeyĀ - 3:36 am local time
With 9+ years of experience in software engineering, I specialize in building robust backend architectures and custom automation scripts that save businesses time and resources. Whether you need a high-performance API or a system to process millions of data points, I deliver clean, maintainable, and enterprise-grade code.
How I Can Help You:
š Backend Development & APIs I build secure and scalable RESTful APIs using Django and FastAPI. From database design (PostgreSQL) to deployment (AWS/Docker), I handle the entire lifecycle of your web application's engine.
āļø Automation & Data Extraction Stop doing repetitive tasks. I develop custom Python scripts to:
Scrape and structure public data from complex websites (Selenium, Playwright).
Automate file processing, reporting, and CRM updates.
Integrate third-party APIs (Stripe, OpenAI, Google Maps) into your workflow.
š Geospatial (GIS) & Advanced Logic Unlike standard developers, I have deep expertise in handling complex spatial data and algorithms (PostGIS, GeoDjango, OpenLayers). If your project involves maps, location intelligence, or heavy data processing, I am the right expert.
My Tech Stack:
Languages: Python (Expert), JavaScript, Golang, SQL.
Frameworks: Django, Django REST Framework (DRF), FastAPI, Flask.
Data & Tools: PostgreSQL, Redis, Docker, Celery, AWS, Git.
Automation: Playwright, BeautifulSoup, Scrapy, Pandas.
I focus on communication and long-term reliability. Letās discuss how we can optimize your backend infrastructure.
Steps for completing your project
After purchasing the project, send requirements so Enis can start the project.
Delivery time starts when Enis receives requirements from you.
Enis works on your project following the steps below.
Revisions may occur after the delivery date.
š Analysis & Config Strategy
We define which AI models (OpenAI, Anthropic, etc.) best fit your budget and use case. I design the API structure and System Prompts based on your requirements.
š» FastAPI Backend Development
I develop the core REST API using Python FastAPI. I implement the logic to handle user requests, send them to the AI model, and stream the response back efficiently.
