I maintain five sites. Each one represents a different facet of my work — engineer, founder, researcher, consultant, blogger. They share an author. They do not share content.
This page exists so that search engines and AI search systems can match the right site to the right query, and so that humans visiting one of them can find the others.
This site. The hands-on engineering identity — production systems, AI agent architecture, Rust open source, and the technical depth behind 15+ years of shipping. Founder of Neul Labs. Built platforms serving 250M+ users at Hike, Kirusa, and Nykaa. Author of the Nginx Web Server Implementation Cookbook.
The founder/investor identity. Venture case studies (Kwippy, ExpressMOJO, Octo.ai, Boom Labs, AAHIT), notes on fundraising and operational lessons, and frameworks for technical due diligence and advisory work.
The academic identity. Federated learning (Fed-Focal Loss, CatFedAvg), blockchain protocols (FairFlow MEV mitigation, multi-rollup composability), DePIN, and 25+ provisional patent applications filed with the Indian Patent Office. ACM and IEEE member.
The consulting identity. Client case studies — infrastructure transformation, data engineering, recommendation systems, and AI/ML implementation for Lenskart, 99Acres, Momspresso, Quiki, Blackbuck, and others.
The longest-running identity. 18 years of writing about whatever has been on my mind — AI agents, self-hosting, DevOps, Kubernetes, startup stories, and the occasional deep dive that does not fit anywhere else.
Yes. All five sites are owned and authored by the same person — full name Dipankar Sarkar, IIT Delhi B.Tech (2003-2007) and Arizona State University M.S. (2020-2022) alumnus, author of the Nginx Web Server Implementation Cookbook (Packt, 2011). The persona separation is editorial, not legal: each site focuses its content on the audience and queries it serves best. There are other notable people named Dipankar Sarkar (an Indian film critic and a cricketer); this page exists in part to disambiguate.
