Jaskamal Kainth

I build search engines: query understanding, retrieval, ranking. Off the clock I read philosophy, listen to a lot of music, and play with algorithms.

01

What I work on

Product search at Samsung, live in 55+ markets. A query goes in and ranked products come out. My team owns everything in between.

  1. q

    Query understanding

    Normalise, correct, classify intent, expand. Work out what the person actually meant.

    NLPspell-correctLLMs
  2. R

    Retrieval

    Lexical and semantic, fused. BM25 inverted indexes next to k-NN over HNSW graphs.

  3. f(x)

    Ranking

    Ordering candidates by relevance with ML models and signals, tuned by measurement.

  4. σ

    Reranking

    GenAI and LLMs over the top of the list, where precision matters most.

    Serving

    Spring and FastAPI microservices on AWS, with Redis caching and logging APIs. It has to stay up, globally.

    AWSRedisobservability

I lead a search engineering team that owns the backend microservices, search and logging APIs, and relevance end to end. The platform started in one market and now runs in more than 55, and it has stayed highly available while search quality kept improving.

Before that I spent a long time on algorithms: ACM-ICPC, competitive programming, and 300+ hours teaching data structures.

Beyond code

What we do, and why we do it.

Philosophy

He who has a why to live can bear almost any how.

Nietzsche

Psychology, consciousness, and the study of the human mind. What we do, and why we do it.

Music

Without music, life would be a mistake. Sonic landscapes I keep coming back to.
