I'm Yogendra Singh Rathore
Most software is built by people who never tried to defeat it. I ship production systems — including an HR platform running a fine-tuned LLM — and I test applications the way an attacker would.
Vulnerabilities reported to Apple and Amazon · two years at Accenture in Data Science and ML · MSc Artificial Intelligence, Liverpool John Moores · CompTIA PenTest+ and Security+
Only 5 clients at a time. Capped on purpose. Discovery first, scope agreed in writing, and you own 100% of the code.

Production systems shipped in Laravel, React, Python and Flutter — then tested the way an attacker would, by the person who built them.
What I do
Eight years building software, since 2017 — two of them at Accenture as a data scientist and then a senior machine learning engineer. I work across the stack, from Laravel and React through to the cloud it runs on, and I test what I build the way an attacker would. I teach the same material live. Below is what I actually work in — for detail, see my resume and the projects further down.
AI, Deep Learning, NLP & LLM
Provide AI and LLM-based solutions tailored to your needs. Built with advanced machine learning frameworks, Natural Language Processing (NLP), and large language models including GPT and Claude — plus MCP servers that connect them securely to your own data and tools.

Here for the security teaching?
Two different things share my name, so here is the split.
Companies hire me to build software and to test it. That is this site — the work above, and the 5-day security sprint.
Students and engineers learning offensive security should go to Core Hacking. That is where the teaching lives: live sessions, deliberately vulnerable labs, and the same material I use on real engagements. I cap each cohort at 30 so every person gets an answer. It is early — the first cohort has not run yet, and if you want to be in it, that is the place to say so.
FAQs
01How do you price a project?
Only once I understand it. We start with a discovery call — sometimes two or three meetings — and then you get a written proposal with the scope, timeline and cost: a fixed price where the work is clear, a phased estimate where it is not. The agreed scope is delivered for the agreed figure; if what you want changes mid-way, we re-quote the change rather than argue about it.
02Who owns the code when we are done?
You own it — all of it. Code and documents transfer to you on final payment, and you get the repository, not a zip file. I keep no rights over work built for you.
03How many clients do you take at once?
Five, so each one gets real attention rather than a queue position. When a seat is full, I will tell you when the next one opens instead of taking your money and starting late.
04Do you work with clients outside India?
Yes. Prices switch to dollars automatically, and I keep two evening slots a week for US and European calls so nobody is taking a meeting at 4am.
05What happens after the project ships?
A month of support is included, and maintenance after that if you want it. You deal with me directly — there is no account manager between you and the person who wrote the code.
06How do I know which of these I need?
Book a call and describe the problem in a sentence. I will tell you which of these fits, or that none of them do if that is the honest answer. I would rather lose the sale than sell you the wrong thing.
