Hi, I'm MD Hamidur Rahman
"I build full-stack web applications, test them the way an attacker would, and automate everything around them with n8n, Python and AI."
What You Get When You Hire Me
Six commitments that apply to every project I take on, whether it is a build, a security audit or an automation.
You get a responsive build tested on real phones, not just a desktop window, with clean handover: source code, credentials and a short walkthrough of how it runs.
I test an application the way an attacker would, then hand over a written report: what is exposed, the exact steps to reproduce it, the severity, and the fix for each finding.
Finding a hole is half the job. I patch it, harden what surrounds it, then re-run the same test to prove it is closed before I call the work done.
Every workflow ships with retries and a failure alert, so a broken run tells you instead of going quiet, and it is documented well enough for you to edit it yourself.
The scripts and API keys stay yours, on your own accounts and your own server. Nothing is hidden behind a service of mine that you have to keep paying for.
Nothing is marked finished on trust. I verify events firing live in GA4 DebugView and Meta Events Manager, and show you the screen where they land.

Frequently Asked Questions
Development, security and automation — the questions clients ask before hiring me.
What kind of websites do you build?
Business sites, admin dashboards and full web applications — front-end, back-end, database and server deployment. You receive the source code and the accounts stay in your name.
Can you test a website you did not build?
Yes. Penetration testing and vulnerability assessment on an existing application is a large part of my work, and it does not matter who wrote the original code.
What is in a security report?
Every finding with the exact steps to reproduce it, how serious it is, and the fix. If you ask me to fix it, I patch it and then re-run the same test to prove the hole is closed.
What can you automate with n8n and Python?
Repetitive work that people currently do by hand: lead capture, notifications, syncing data between two systems, scheduled reports, scraping and cleaning data. Each workflow ships with retries and a failure alert.
Do you set up analytics and conversion tracking?
Yes — SEO groundwork, Google Analytics 4 and Meta Pixel. I verify the events firing live in GA4 DebugView and Meta Events Manager before I hand the work over.
