Ujjwal Singh Baghel
Founder, Ful, Inc. · Systems & Crawling Infrastructure
I design, build, and operate large-scale web crawling and technographic-intelligence systems — the kind of unglamorous infrastructure that powers lead generation, competitive intelligence, and martech data products. I run Ful, Inc. end-to-end: product, backend, infra, and the data pipeline underneath all of it.
Two companies, built from the ground up — product, infra, and everything underneath.
A B2B technology-intelligence platform. Ful.io tells you what tech stack any website runs, tracks changes over time, and turns technology signals into leads — domain lookups, technographic reports, and an API, backed by a crawling engine I built and operate. Full stack is mine: Django/DRF backend, Next.js frontend, MySQL at scale, AWS infrastructure.
ful.io ↗An independent media and digital-products company I run in parallel, based in India — the entity behind Binc.Network, a growing network of content channels. Separate books, separate focus from Ful.
binc.network ↗The engine behind Ful.io — and the part of this I actually want to talk to people about.
A distributed, multi-engine crawler that fingerprints the technology stack of tens of millions of domains, detects 1,500+ technologies, and keeps the dataset fresh on a continuous re-crawl cycle. Built from scratch: distributed fetch workers across cloud and residential routes, TLS-fingerprint–aware fetching to get past anti-bot defenses cleanly, Aho-Corasick pattern matching for detection at speed, and a confirmation pipeline that double-checks a signal before it's trusted.
This isn't a self-serve tool, and that's deliberate — I'm not opening it up for anyone to run jobs against. If you want technographic data, crawling infrastructure for your own product, or just want to talk shop about scraping at scale, that's a conversation I'm glad to have.
Let's talkConsulting, collaboration, or hands-on build work — not a product signup.
Designing and operating crawlers that fingerprint tech stacks, detect change, and hold up at tens of millions of URLs without falling over.
Schema design, migrations, and query performance on billion-row tables — MySQL and Postgres, in production, not in theory.
Django/DRF + Next.js/React, from API design to a production deploy on AWS. I ship the whole thing, not just a layer of it.
TLS impersonation, residential routing, and detection-evasion used for legitimate data collection — not abuse.
I've run a company end-to-end — product, infra, GTM, and the unglamorous parts in between. Happy to be a sounding board.
Smaller, personal projects alongside the main work.
