I'm on the founding team at Datatailr, split about evenly between two products. Half my time goes to our query engine, a high-speed federation engine that reads across everything at once. The other half goes to the platform quants and HFT traders run their strategies on, where I own the infrastructure and DevOps. I'm also the lead AI engineer here, so I run the AI features we're adding.
Two products, split about evenly, and the AI work sitting over both. Pick a node.
Two products, and the AI over both.
I've been at Datatailr since 2023, on the founding team, and my time splits about evenly between two products. The first is our query engine: a high-speed federation engine that answers across more than 100,000 tables without moving any of them.
The second is the Datatailr platform itself, which quants and HFT traders use to run their strategies without having to think about what's underneath. I work on the infrastructure and DevOps side of it: infrastructure-as-code across four clouds, the private networking on Azure, the DAG scheduler that runs batch work, and the deploy pipelines and monitoring around all of it.
I'm also the lead AI engineer here. We're adding AI features across the product and I run that work: retrieval, vector search, embeddings and MCP servers.
Before that I wrote Rust at Juspay on Hyperswitch, their open-source payment orchestrator. Before that, internships at IBM and Brane, and a GitHub Externship with Suborbital where I spent a few months writing WebAssembly runnables.
I didn't start in engineering. Most of my first paid work was posters, logos and UI for small companies, and I still take the visual side of a project when it needs one. I've also been doing competitive programming since school, which is where most of my problem-solving habits come from.

2023 — now
Founding Engineer, Lead AI Datatailr
Split across two products. Build the query engine, a federated SQL layer over 100K+ tables that took query times down about 90%. On the Datatailr platform itself, own the infrastructure and DevOps: multi-cloud infrastructure-as-code across AWS, Azure, GCP and Hetzner, private networking on Azure, and DAG-based batch orchestration, which took compute spend down about 75%. Now lead the AI work: retrieval, vector search and MCP servers.
