About me
Table of Contents
I’m Vishal Bhargava. I build and run systems that have to work in the real world — not just in clean diagrams.
Most of my career has been platform and infrastructure work: delivery pipelines, internal tooling, and the foundations other engineers depend on. Twelve years of it. I tend to care about reliability, debugging, and cost more than novelty.
These days I apply that same platform mindset to LLM systems — not from a research angle, but an operational one. How they get deployed, observed, and paid for. The part I keep coming back to is inference cost: it’s the line item that surprises teams, it’s rarely measured properly, and it’s usually treated as a model problem when it’s an infrastructure problem. Measurement, routing, and serving efficiency move it far more than swapping models does.
What I’m working on #
- ritam — an end-to-end RAG service (API, infra, evals, dashboards) I keep building in the open as a way to work through these problems properly rather than theoretically.
- Cost and latency per stage — embed → retrieve → generate, measured rather than guessed.
- Retrieval quality — chunking, hybrid search, and evals that tell you whether a change actually helped.
Quick facts #
- Platform/infrastructure engineer, ~12 years across AWS, Kubernetes, and Terraform
- Tech Lead Manager, Platform @ Kittl — remote, for a Berlin team
- Based in Dubai since early 2026, after seven years in Berlin
Outside of work, I care a lot about food. I cook often, experiment a lot, and probably overthink simple dishes more than necessary. It’s one of the few places where I enjoy slowing down and paying attention to small details.
This site is where I write things down — about work, projects, and change — when they’re worth thinking through properly.
Get in touch #
If you’re running LLM systems in production and wrestling with inference cost, serving, retrieval, or evals, I’d like to hear about it. Mail me at [email protected] — I read everything and reply to most of it.
