You will get an AI SaaS MVP with Python, FastAPI & LLM
Top Rated

Project details
Have an AI product idea but need the technical path to turn it into a real, working product?
You will get an AI MVP built from idea to deployment, not just a prototype or isolated AI integration. I can help shape the product architecture, build the application, integrate the AI layer, connect the database and APIs, and prepare it for production.
Depending on your requirements, your MVP can include AI agents, LLM integrations, RAG and knowledge-base systems, intelligent automation, AI-powered SaaS features, dashboards, authentication, APIs, and third-party integrations.
My approach combines AI engineering with full-stack product development, so the AI functionality is built as part of a complete, usable application.
Typical technology stack: Python, FastAPI, OpenAI/LLM APIs, React/Next.js, PostgreSQL, Supabase and modern cloud infrastructure.
You will receive clean source code, scalable architecture, responsive implementation, testing, and deployment based on the package selected.
If you have an idea but are unsure about the best architecture or AI approach, that is completely fine. We can define the right technical direction before development begins.

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 - 10:54 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.
