Ujjwal Singh Baghel

Founder, Ful, Inc. · Systems & Crawling Infrastructure

I build the data infrastructure other products quietly run on.

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.

40M+ domains indexed
1,500+ technologies fingerprinted
1B+ domain↔tech data points
2 companies built & run

What I run

Two companies, built from the ground up — product, infra, and everything underneath.

Ful, Inc.

Delaware C-Corp

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.

Bincmedia Network Pvt. Ltd.

India

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.

The crawler

The engine behind Ful.io — and the part of this I actually want to talk to people about.

Crawler Attractor — technographic intelligence at scale

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 talk
  • ScaleTens of millions of domains, continuously re-checked
  • Detection1,500+ technologies across 25+ categories
  • ResilienceTLS impersonation + residential routing for hard targets
  • AccuracyTwo-pass confirmation before any signal is written back
  • StackPython, Playwright, custom fetch layer, MySQL, Redis

What I can help with

Consulting, collaboration, or hands-on build work — not a product signup.

Crawling & technographic infra

Designing and operating crawlers that fingerprint tech stacks, detect change, and hold up at tens of millions of URLs without falling over.

Data platforms at scale

Schema design, migrations, and query performance on billion-row tables — MySQL and Postgres, in production, not in theory.

Full-stack product engineering

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.

Resilient, responsible scraping

TLS impersonation, residential routing, and detection-evasion used for legitimate data collection — not abuse.

Technical founder support

I've run a company end-to-end — product, infra, GTM, and the unglamorous parts in between. Happy to be a sounding board.
