You will get a custom Generative AI Agent with RAG, LLM, OpenAI & API integration
Top Rated
Project details
Turn your business data, documents, and workflows into a custom AI agent that can actually perform useful work not just generate generic chatbot responses.
I will design and develop a custom AI agent tailored to your use case, with RAG, LLM integration, knowledge-base search, database connectivity, and third-party API integrations where required.
Depending on your package, the solution can include document ingestion, vector search, conversational AI, structured responses, tool/function calling, workflow automation, database integration, testing, optimisation, and production deployment.
Suitable for: internal knowledge assistants, customer support agents, document Q&A, business automation, research assistants, and API-connected AI agents.
The focus is not simply connecting an LLM API I build the surrounding architecture needed to make the agent reliable, maintainable, secure, and ready for real-world use.
Typical technology stack: Python, FastAPI, OpenAI/LLMs, RAG, vector databases, PostgreSQL, REST APIs, and modern cloud infrastructure.
If you have an idea but are unsure about the right architecture, I can help define the technical approach before implementation.

Custom websiste and mobile App developement
We had a fantastic experience working with Kretoss Technology for our mobile app and website development. From the initial planning phase to final delivery, their team was professional, responsive, and technically skilled. They clearly understood our vision and turned it into a high-quality, user-friendly product that exceeded our expectations.
What stood out most was their attention to detail, timely communication, and ability to handle complex functionality with ease. The app runs smoothly on both iOS and Android, and the website looks modern, fast, and fully responsive.
If you're looking for a reliable development partner, I highly recommend Kretoss Technology — they truly deliver excellent results!

Job Success
Shapar -Veraval, India - 4:34 am local time
With 8+ years in software engineering, I work across the complete product lifecycle from Python backends and AI systems to modern frontend applications, APIs, databases, cloud infrastructure, and production deployment.
Give me an idea, an existing codebase, or a system that needs scaling I can take ownership from architecture to launch and beyond.
A little more about what I do:
• Python, FastAPI, Django & Flask development
• AI Agents, LLM integrations & intelligent workflows
• React, Next.js, Node.js & TypeScript applications
• Native and cross platform mobile app development
• SaaS platforms & custom business applications
• REST APIs, third-party integrations & automation
• PostgreSQL, MongoDB, Supabase & Firebase
• Shopify & custom eCommerce development
• Docker, AWS, Google Cloud, CI/CD & deployments
• Performance optimization, refactoring & scaling
If you need deep Python/AI expertise, I can handle it. If you need the entire product engineered, integrated, deployed, and scaled I can own that too.
🔧 EXPERTISE:
Python | FastAPI | AI Development | AI Agents | LLM | OpenAI API | Django | React | Next.js | Node.js | TypeScript | PostgreSQL | Supabase | Shopify | Docker | AWS | Google Cloud | API Integration | SaaS Development | Mobile App Development | Cross Platform App Development
