Ethiraj Srinivasan
Engineer by craft. Founder by choice.
I'm Ethiraj Srinivasan — Co-Founder & CTO at InfiniTraq, and Consultant, Head of Data Engineering at Zgrow Solutions. Over a decade building software, data platforms, and products — and taking on a small number of engagements outside InfiniTraq.
About
From Rails apps to data at scale — and founding.
I'm currently building InfiniTraq, a privacy-first AI guardian for senior care, as Co-Founder & CTO of Griffin AI Tech, and Consultant, Head of Data Engineering at Zgrow Solutions in Chennai.
I started as a software engineer at TCS and Pramati (Ruby on Rails, web apps), then moved into big data and analytics at Knorex, Lomotif, and five years at Shopee, Singapore.
M.Tech in Software Engineering from NUS. My toolkit spans Spark, Hadoop, Kafka, Hudi, Hive, HBase, AWS (EMR, S3, Athena), Python, Spring Boot, Ruby on Rails, and increasingly — Edge AI for video intelligence.
More about meCurrently Building
InfiniTraq — a 24/7 caretaker that never sleeps.
An AI guardian for senior living. InfiniTraq continuously monitors for falls, inactivity, and daily activities using non-visual sensors and Edge AI — no cameras in private rooms, no cloud streaming, response in under 5 seconds.
- Privacy-first by design
- No cameras in private rooms
- Sub-5-second alerts
- NVIDIA-powered Edge AI
