Mohammad Ehdaie

Mohammad Ehdaie is a Product Manager at PKI Company. He likes to research, to create, and to present. He likes to plan, to generate ideas, to lead a team, and to meet the mission.

He is interested in designing algorithms and protocols. He started programming when he was 7. He well knows how to make creative solutions for problems.

His intelligence brought to him a dozen of scientific achievements, such as ranking 39-th amongst 450,000 participants in national university entrance exam and studying in the best university of Iran.

Since he is passionate about teaching and presenting, he started teaching at Sharif university when he was a MSc student. He showed a great ability as a teacher and taught programming to 2,000+ talented students.

When he was a PhD student, he organized a group of motivated students for scientific activities. During 2 years, he organized 4 workshops and conferences at international level with 500+ participants in total. Those activities were a clear example of planning, team-working, and leading.

Now, he leads Mobile Signature Service, a national project for MCI (main mobile operator in Iran). He well knows how to manage the things, to prioritize the work-load, and to present to C-level managers.

He still seeks better opportunities to utilize his skills in a larger scale. I am alive to not stop.
