Selected work

Two AI products I build and run outside my day job, on one shared platform, and the Amazon work I can describe in public. The product case studies cover the problem, what I built, the tradeoffs, what went wrong and what I’d change at ten times the size; the Amazon one keeps to what I have published. Every fact links to a public source.

Case studies

  1. Clarity Today

    Outside work · I build and run it

    A daily news product where language models write every story, every claim carries its source, and a story that can’t back its own citations doesn’t publish.

  2. RetailIntel

    Outside work · I build and run it

    Retail intelligence for people making consequential retail decisions in India. A chain of AI agents reads 79 publications and files cited signals, each with a forecast and a counter-case.

  3. Amazon Music: fraud and content moderation

    2021 – 2022 · Senior Lead Software Engineer, Amazon Music

    The team that built automated policy-violation detection for the Music catalog and a streaming fraud platform. Told from what I have published, without Amazon’s internal detail.

Earlier at Amazon

Semantic search on the product detail page

2017 – 2020 · Software Development Engineer, Amazon.in

On the Product Detail Page Platform team in Amazon.in’s retail organisation: semantic search on the detail page with deep-learning models and approximate nearest-neighbour lookups, then an offer-aggregation platform behind Home, Search and the detail page.

Source: LinkedIn: experience

Amazon work is described as I published it on LinkedIn: titles, team scope and what we built, with no internal numbers. Views are my own, not Amazon’s.
