Project details
Turn your SaaS idea into a modern, functional web application built with Next.js, React, Supabase & TypeScript.
Whether you're starting an MVP, building a new SaaS feature, or improving an existing application, I'll help you turn the requirement into a clean, responsive and scalable product.
Using a modern stack with Next.js, React, Supabase and TypeScript, I can handle frontend development, database, authentication, APIs, integrations and core SaaS functionality.
What makes this project different:
✓ Product-focused development, not just coding
✓ Modern and responsive UI
✓ Fast development using Supabase
✓ Secure authentication and database architecture
✓ Clean, maintainable TypeScript code
✓ API and third-party integrations
✓ Scalable foundation for future features
Important: Package scope is based on the selected tier. Complex SaaS platforms, extensive integrations, or larger feature sets can be handled through a custom offer.

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!

Shapar -Veraval, India - 7:18 pm 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.
