Beginning in 2005, he worked as a senior high school mathematics teacher for three years, and in 2008 he worked as a lecturer in mathematics education in an institute of teacher training and education science for one year. In 2009, he started a new job as a civil servant lecturer at the Department of Mathematics of the Faculty of Mathematics and Natural Sciences, Universitas Negeri Semarang.

He also has experience as an academic staff member at the Centre of Development of Education Media (PPMP), Universitas Negeri Semarang, and as a reviewer of Interactive Educational Multimedia Production at the Department of ICT Development for Education (BPTIKP), Central Java, Indonesia. He teaches mathematics education, especially teaching and learning geometry and the use of ICT in Mathematics Education, and he has conducted several research projects in these areas. He has presented and published several papers in his research area in national and international forums and scientific journals. In 2006, he was recognised as the winner of a competition of teachers with smart ideas held by Citibank Indonesia and the Indonesian Hope Foundation.

In 2013, he was awarded a PhD scholarship from the Islamic Development Bank (IDB), Jeddah, Saudi Arabia, through an IDB-UNNES PhD fellowship program. In the same year, he started his PhD study at the Institute for Mathematics and Computer Science Education, J. W. v. Goethe-University Frankfurt am Main, Germany, under the supervision of Prof. Dr. Matthias Ludwig from Goethe Universit Frankfurt and Professor Marc Schaefer, Ph.D from Rhodes University, South Africa. His PhD research focused on the MathCityMap-Project for Indonesia. In 2017 he was awarded a doctoral degree in Natural Sciences (Dr.rer.nat.) in the speciality of Didactics of Mathematics after he furnished evidence of his ability in regularly conducted doctoral proceedings through his dissertation entitled „Learning mathematics in a mobile app supported math trail environment“. In the same year, he resumed his position as a lecturer at Universitas Negeri Semarang to teach in the Undergraduate Program and Postgraduate Program of mathematics education.
