Saurav Gupta, Software Development Engineer II at Amazon

I build systems at Amazon, and teach the ideas behind them.

Software Development Engineer II at Amazon, four years in. Currently migrating Alexa Daily Essentials onto Alexa+, Amazon's Gen AI assistant. Previously on Finance Tech services running at millions of transactions per second.

What I am working on

Alexa+, Gen AI in production. Re-modelling deterministic intent handlers as agentic, tool-calling flows. The hard part is not prompting, it is keeping a non-deterministic model inside latency and accuracy budgets that were written for deterministic code.

learn.sauravgpt.in, the course I wanted when I started. Most system design material is either a listicle or a 900-page book. This is my attempt at the middle: short, engineering-first lessons that build in order. 63 lessons across 12 modules, all written by me, and the content is open source.

Selected work

Project What it is Links

The lessons behind learn.sauravgpt.in live in a public repo. Fixing a wrong claim, tightening an explanation or adding a lesson is a pull request away.

Say hello

Happy to talk about Gen AI in production, system design, or anything at the awkward intersection of scale and correctness.
