After many years working in the field of AI as an independent contractor, I founded TETSAB LLC, a company focused on providing small businesses with generative AI solutions.
From strategic consulting to implementing tools like chatbots and automation, we guide businesses through their AI journey, helping them streamline processes, increase efficiency, and achieve sustainable growth.
We also specialize in providing high-quality AI training and data annotation services for larger companies. Having worked extensively in this space, I know that well-labeled, robust data is essential for building successful models.

My previous experiences in communication and marketing, education, editing and proofreading, as well as my multilingualism became serious advantages when I entered the emerging world of generative AI. When I started working on the early models, I was impressed at how they could produce some acceptable outputs to most queries. Despite a high rate of inaccuracies, the occasional lack of political correctness and the high level of verbosity, it felt somewhat magical. I wouldn’t have imagined how fast the models would evolve into humanlike assistants, able to handle real-time discussions or just generate a picture with the right count of hands. Let alone videos! This journey into AI has been an exciting one, and I am glad to be (a small) part of it.

Outside work, I’m a passionate traveler with a love for exploring new cultures and perspectives. Travel isn’t just a personal interest for me – it’s a source of professional inspiration and a lifestyle. Working remotely from different parts of the world, I draw on the experiences, challenges, and connections I encounter in order to bring fresh ideas and a global perspective to my work.

Whether it’s hiking a scenic trail, sampling local cuisine, or cultural exchanges, I find that these experiences sharpen my creativity and broaden my outlook. They also enhance the work I do at TETSAB, as I strive to bring a unique blend of innovation, adaptability, and cultural awareness to every project.

When I get a chance, I like to support social projects in youth and education. Adolescence in particular is a time when one needs to find the support and the resources needed to grow. Not every child is the same, and while I support traditional education, I believe we can support our kids with alternative forms of education, especially project-based learning. We’re not the ones teaching them, we’re the ones helping them to learn. While AI might accelerate a leaning towards this approach, it’s important to provide the future generations with more tools than ever.

I enjoy good discussions and new challenges. If you’d like to connect, please message me on LinkedIn, or send me an email through the contact form on this site.
