EdTech
Also known as: Educational Technology · Ed-Tech
EdTech is the engineering of learning and assessment software, often at the intersection of consumer-grade UX and institutional procurement. The architectural pressure in TantraDev's EdTech work is tier-2/3 Indian market reality: low-end Android, intermittent bandwidth, low ARPU. The system has to be offline-first, infrastructure-cost has to be sub-dollar per active user per month, and the personalisation loop (ML adaptive difficulty) has to work without round-tripping to a model on every interaction.

Concepts that travel with this one.
Architecture rarely lives in isolation — these are the terms that come up in the same conversation.
React Native
React Native compiles a single TypeScript/React codebase down to native iOS and Android. TantraDev uses it where a founding team has one product roadmap and two app-store targets — particularly EdTech and consumer apps headed to tier-2 and tier-3 Indian markets where Android dominates and bandwidth is the constraint. Native modules cover the 10% the bridge can't reach.
TensorFlow
TensorFlow is Google's ML framework, strongest for production-grade model serving (TensorFlow Serving), mobile inference (TFLite), and large-scale training pipelines. TantraDev uses TensorFlow when the model leaves the notebook — when something has to be quantised for an Android phone, served behind a latency SLO, or trained on a multi-GPU cluster. For experimentation we are equally at home in PyTorch.
