Frequently Asked Questions

Quick answers about working with me, the courses, the books, and this site.

What does Raihan Khan do?

I'm a technology and project leader working in e-Government Procurement (e-GP) and public-sector digital transformation, currently as IT Manager at Management and Training International Ltd. Alongside that, I'm an independent researcher in trustworthy AI, and I run three ventures: ABCL TECH, Visa Bangla, and Chakri Bangla. More on the About page.

How can I contact you for collaboration or consulting?

The fastest way is the contact form, or email raihankhancs@gmail.com directly. I read every message.

Are the ABCL TECH courses really free?

Yes. All 28 courses on ABCL TECH, from core programming to AI and machine learning, are free with no sign-up or paywall.

How do I buy the IELTS eBooks?

Each book on the Books page links to its page on Visa Bangla, where you can read a free demo before buying and order via WhatsApp. Books are ৳150 each, or all six paid modules together for ৳700.

What is e-GP / e-Government Procurement?

e-GP is the digital system governments use to run public procurement, tenders, and contracts transparently online instead of on paper. Most of my professional career has been spent building and managing e-GP-adjacent systems for Bangladeshi ministries — see Experience for the details.

Do you offer visa consultancy services directly?

Visa consultancy is handled through Visa Bangla, the venture I founded for that purpose. It's a separate site with its own contact channels.

Can I use content from this site?

You're welcome to quote or link to individual pages with attribution. Bulk republishing or scraping isn't permitted — see the Terms & Conditions for details.

Do you take on freelance or contract work?

I evaluate opportunities case by case around my full-time role. Reach out through the Contact page with details and I'll let you know if it's something I can take on.

Where can I find your resume/CV?

You can download it directly from the homepage — look for the "Resume" box under my name — or view the full breakdown on the Experience and Skills pages.

How is my data handled if I use the contact form?

Your message is sent through Formspree to my inbox so I can reply — nothing more. Full details are in the Privacy Policy.
