I lead AI at Datatailr, which builds computing tools for hedge funds and high-frequency traders. The AI work is mine, along with the infrastructure and DevOps under the platform. I also work on the query engine, a federation layer over 100,000+ tables.

What Kritik works on at Datatailr. The AI work he leads sits above the two products it goes into, drawn dashed because it is still being built.

about

Datatailr, since 2023.

I joined Datatailr in 2023 on the founding team and I'm the lead AI engineer now. I run the retrieval work. That means pipelines, vector search, embeddings, and MCP servers that expose them to a model.

The rest of my week splits between two products. One is the Datatailr platform, where quants and high-frequency traders run their strategies. I handle everything under it: infrastructure-as-code across AWS, Azure, GCP and Hetzner, private networking on Azure, the DAG scheduler behind every batch job, deploy pipelines, monitoring. Right-sizing that stack cut the compute bill by three quarters.

The other is the query engine. It answers across more than 100,000 tables without copying any of them, and it runs roughly ten times faster than what it replaced.

Before Datatailr I wrote Rust at Juspay on Hyperswitch, their open-source payment orchestrator. Earlier than that, internships at IBM and Brane, and a GitHub Externship with Suborbital writing WebAssembly runnables.

      Now

    2. Founding Engineer

      From 2023

    Lead the AI work, from retrieval and vector search through to embeddings and MCP servers. Own infrastructure and DevOps on the platform: Terraform across four clouds, a private network cluster on Azure, DAG-based batch orchestration, CI/CD, 75% off the compute bill. Also work on the query engine, a Trino layer over Postgres, Snowflake, BigQuery, Redshift, Hive, S3 and MySQL, cutting heavy query runtimes by 90% and letting quants join across sources with no ETL step. 10+ business deployments, +250% ARR, a $500k pipeline, and direct work with enterprise clients on rollouts.

An AI assistant can edit anything in a repo, but not a video or a deck. Both of these keep the content in files, so it can rebuild either one.

Product video as code Product videos built from a repo. An animated HTML deck, an AI voiceover and real screen recordings, mastered and rendered to MP4 with ffmpeg. The audio is generated and measured before any timing is fixed, so scene durations follow the narration. script.json → tts → measure → render → composite → mp4 Python · Playwright · ffmpeg · MIT Deckloom Decks built from a repo. Content lives in one JSON file, the design in another, and headless Chrome renders them at PowerPoint's page size.
