Founder of DET Study • Remote Educator • Online Entrepreneur

Welcome, and thank you for visiting my professional portfolio.

I am the founder of DET Study, an online education platform dedicated to helping students prepare for the Duolingo English Test through AI-powered learning, educational content, and innovative study tools. My goal is to make English language education more accessible by combining years of teaching experience with modern technology.

For more than 15 years, I have worked in English language education, teaching students from around the world while developing digital resources that support independent learning. Today, I continue to manage and grow DET Study as a fully remote business, creating educational content, developing new learning tools, and supporting a global community of English learners.

What is DET Study?

DET Study was created to give students a place to prepare for the Duolingo English Test using practice questions and AI-powered scoring designed to closely reflect the real testing experience. The goal was to provide learners with realistic feedback, helping them better understand their current English proficiency and identify areas for improvement before taking the official exam.

Built on more than 15 years of English language teaching experience, the platform offers over 15,000 practice questions, video lessons, AI feedback, and study resources for learners around the world. DET Study is fully developed, managed, and continuously updated remotely, with new content and features added on a regular basis.

Educational Content

I regularly produce educational videos for the DET Study YouTube channel, covering Duolingo English Test strategies, test requirements, and practical guidance to help students prepare with confidence.

Business Operations

DET Study is an independently owned and operated online business that I manage entirely remotely. My responsibilities include website administration, educational content creation, AI-powered learning tools, video production, customer support, and ongoing platform development.

The business serves students around the world through online subscriptions and the sale of official Duolingo English Test discount vouchers, with secure payments processed through Stripe. Because all operations are conducted online, the business can be managed from any location.

Conclusion

This portfolio provides an overview of my professional background, the DET Study platform, and the fully remote nature of my work. It reflects the business I have built, the educational resources I continue to develop, and the ongoing management of an online platform serving students around the world.
