Education
2010 - 2015
BSc Mechanical Engineering
KUET
I studied Mechanical Engineering at Khulna University of Engineering & Technology. But I realized that my true passion lies in software engineering, a field that I couldn't fully explore within the confines of my university curriculum. I had an overwhelming desire to immerse myself in the world of software development and acquire practical skills that would enable me to bring my ideas to life. For that over the past 8 years, I have dedicated myself to an intensive self-study program, which has allowed me to delve into various programming languages, development frameworks, and software engineering principles. I have been fortunate to access a wealth of online resources, engage in coding projects, and collaborate with other passionate individuals within the software engineering community. This journey has not only broadened my technical expertise but also strengthened my problem-solving and critical thinking abilities.

Ahmad Matyana
CO-Founder/ Alethea AI
Pankaj was really patient and understanding of our needs, and we felt very safe with working with him. He is very knowledgable and skilled, and was great at communication. The scope of our project changed so we had to pause our collaboration, looking forward to working with him again.

Bhabin Shah
Co-Founder/ Anekonnect Incorporated
Pankaj is a good communicator, understands requirements and delivers on the tasks at hand on time. He has shown great proficiency with React, Typescript and Node JS. He learned about WYSIWYG with us and has now mastered his skills with SVG. He would be a great asset to any web design project or any web-based design application that needs to work more or less like draw.io or MS Visio. Funds permitting, I will definitely hire him in the future
