š I Build SaaS Platforms That Ship Fast ā With AI Baked In From Day One
You have a product idea. You need it built right ā scalable, fast, and with AI that works. That's what I do.
8+ years building production-grade SaaS for real businesses. Not prototypes. Not templates. Real products.
āāāāāāāāāāāāāāāāāāā
What you get:
ā Full-stack app: React/Next.js + Node.js + MongoDB
ā AI features: chatbots, smart search, RAG, content gen
ā Auth, roles & team workspaces
ā Admin dashboards with real-time analytics
ā Stripe billing: subscriptions, trials, usage-based
ā REST or GraphQL APIs built for speed
ā Responsive on every screen
ā Deployed and production-ready
āāāāāāāāāāāāāāāāāāā
What makes me different:
I don't just code ā I think product. Database design, user flows, scaling, AI architecture ā planned before I touch the editor.
You get clean code, documented. A product that handles real traffic. AI that adds real value. One developer owning everything start to finish.

Full Stack Devs Needed, Join our team! (NodeJS and Angular)
Shiv helped us to move our Angular 11 project forward by adding new features. He worked mainly on the front end of the application and this is where his skills seemed to be best suited. He worked on a range of areas to help improve our system. He had good communication skills and would sometimes fix up bugs and apply fixes out of hours so that other team members were able to continue their work which was good. Thanks Shiv!
