Project details
I will integrate AI capabilities into your backend system, API, or microservice.
If you want to add AI features to your product but don't know how to integrate LLMs into your existing architecture, I can help.
I have extensive experience building backend systems and integrating modern AI APIs into production environments.
Typical AI integrations I deliver:
• ChatGPT / LLM API integration
• AI-powered REST APIs
• AI text processing and classification
• Document and PDF analysis
• AI automation workflows
• AI features integrated into SaaS products
I can work with existing systems or create a new backend service.
Technologies I commonly use:
• Java / Spring Boot
• Python
• REST APIs
• Microservices
• Cloud integrations
Perfect for:
• SaaS products
• Startups validating AI ideas
• Businesses adding AI features
• Automations using LLMs
If you have an AI idea and want to turn it into a real working backend solution, feel free to contact me before ordering.

Unix Shell Script Expert for Java
Alex is a top-notch technical architect and one of the best I’ve worked with on Upwork. He provided valuable insights and helped design a customized approach to split and reprocess 100k+ claims into multiple files instead of a single large file, which was critical for handling the volume efficiently.
He is professional, knowledgeable, and great to work with. I would definitely work with him again.
