Hi, I'm Nirav Modi.
I'm an AI Engineer, Solution Architect, and Senior Software Engineer with 14+ years of software engineering experience. I help startups, SaaS companies, and enterprises build AI products, AI SaaS platforms, AI agents, automation systems, and enterprise applications.
I can help you from the first idea to a production-ready product. I can also join an existing project, add AI features, improve the architecture, fix technical problems, or help scale your application.
I don't just build AI demos. I focus on building software that is reliable, secure, scalable, and easy to maintain.
What I Can Build
→ AI SaaS Products

The goal is simple: help your users find the right information quickly and get useful answers from your own business data.

→ Appointment booking
→ Sales calls
→ Call automation
→ Voice assistants
These systems can connect with your CRM, calendar, APIs, databases, and other business tools.

4. Test — I test the system for functionality, performance, security, and reliability.
5. Launch — I help deploy the product and prepare it for real users.
6. Support — I can continue helping with improvements, maintenance, and scaling.
