Meet the Founder

Education & Experience

Raihan Khan graduated with First Class in Computer Science and Engineering (CSE) from North South University. Starting with web design in 2015, he has built hands-on experience step by step over more than a decade — software development, systems analysis, system architecture and leading the IT teams of several government projects.

Through his work on national-level government and international digital projects, he has gained practical experience in building and running large-scale systems: designing digital archives and data-preservation systems for historically important records, online classroom and training-management software, strengthening the digital capacity of government monitoring and evaluation systems, and implementing e-Government systems for ministries and European Union-funded initiatives. Turning policy goals into working, reliable technology is the experience that underpins every one of his ventures.

Visa Bangla grew out of years of hands-on visa consultancy and application submission for Bangladeshi travellers, students and workers across Asia, Africa, Europe, North America, South America and Oceania. His experience building online examination systems — participant registration, timed pre-test and post-test examinations, automated results and analytical reporting for training portals — is what powers Visa Bangla's free interactive IELTS, PTE and GRE practice tests. Since 2018 he has also worked on technical specifications, budget analysis and contract management for e-GP tenders; that experience is where e-GP Bangla began.

He keeps his skills current through regular training — advanced training in software architecture, cloud, agile and artificial intelligence, a PMI-authorised PMP exam-prep course, government e-tendering training and ISO 14001:2015 Internal Auditor certification. He holds an IELTS band 7.

More recently he has been doing independent research on trustworthy, human-centred artificial intelligence (Trustworthy AI) — in particular hallucination measurement in large language models, retrieval-augmented generation and natural language processing for low-resource Bangla.

Vision & the Mission of Visa Bangla

He believes that clear, honest guidance about going abroad should not depend on who you know or what you can pay. The same approach he developed on government and international projects — making complex processes simple and transparent — shapes every country guide and practice test on Visa Bangla, so that a traveller, student or worker can understand the requirements, prepare the documents and get exam-ready from home.

With that aim, Visa Bangla has grown into one of the largest resources of its kind in Bangladesh: in-depth visa guides for 195 countries across study, work, tourist, medical and on-arrival categories, 200+ free interactive IELTS, PTE and GRE practice tests, grammar and vocabulary guides, eBooks, and a weekly news digest on visa and migration changes that affect Bangladeshis.
