More about meHi, I'm Devatraj. Backend & AI engineer at Info Edge.
I build AI systems that replace what companies pay for.
I turn expensive vendors, slow AI features and fragile backends into systems your team owns, and I prove they work before anything switches over.
2nd house, wealth
The 2nd house is wealth. Replaced a paid astrology API with milanSathi, an in-house AI-powered astrology engine. Same answers, about $45,000 a year cheaper.
- ~$45,000/year saved
- 100% parity with the vendor on everything tested

How I work
“Prove it, don't trust it.”
A replacement ships only after it's checked against the system it replaces, and against first principles where the old system is wrong.

Replace what you pay for
If a vendor bill grows with your traffic, I build the in-house version and prove it gives the same answers before you switch.

Most LLM bills pay for the same answer many times over. I cut repeat calls with semantic caching and keep answers reliable with fallbacks.
