Thanasis D - A Level Computer Science Tutor

Thanassis D had always seen learning as a map—layered, dynamic, and waiting to be explored. His studies in Computer Science and Earth Observation had sparked a lifelong pursuit: to bridge the technical with the human, the satellite with the classroom.

Each morning, he stepped into the American College of Greece not just as a teacher, but as a mentor within the International Baccalaureate (IB) program. His students didn’t just memorize code—they trained AI models, analyzed real-world datasets, and asked big questions. Under his guidance, classrooms transformed into innovation labs.

Thanassis D has more than six years of experience providing private tuition in Computer Science and Information Technology, including support for GCSE, IGCSE and A-Level students. He teaches core areas such as programming, algorithms, computational thinking, data structures, databases, computer systems, networking and data representation, with a strong emphasis on problem solving, exam preparation and developing students’ confidence with programming. He is comfortable adapting his teaching to different specifications and assessment formats.

By afternoon, Thanassis shifted roles, contributing to cutting-edge projects at the National Observatory of Athens. There, amidst servers and satellite feeds, he designed algorithms to predict floods, track wildfires, and model crop growth. His work wasn’t theoretical—it helped shape the response to real disasters across Europe.

Evenings often brought a different challenge: leading software architecture and engineering efforts at OpenGIS, where he helped build and scale QFieldCloud—a platform empowering geospatial scientists and NGOs worldwide. He balanced usability with scientific power, always pushing toward open, accessible Earth Observation tools.

In the summer of 2024, Thanassis co-designed and mentored at the IGARSS Summer School in Athens, welcoming students from around the globe. With warmth and clarity, he taught them how to turn noisy satellite data into environmental insight. His sessions were among the most remembered—where theory met purpose.

Beyond fieldwork and programming, Thanassis was a writer. His research papers explored the intersection of AI and remote sensing, published in reputable journals and presented at international conferences.

But perhaps his most heartfelt work was in education. He organized workshops on AI in Education, helping fellow teachers harness machine learning not as a buzzword, but as a meaningful classroom tool. In spring 2025, he led a school-wide professional development series for the entire American College of Greece, where educators from every department explored what it meant to teach in the age of algorithms.

Some knew him as a scientist, others as a teacher, a mentor, or a developer. But to everyone who crossed his path, Thanassis D was someone who believed in making knowledge practical—and empowering others to do the same.
