I'm Pankaj Vasava, a Computer Science & Engineering student focused on building reliable, secure, and practical software solutions.
My engineering journey began with a Diploma in Mechanical Engineering and professional experience in Quality Assurance & Quality Control. This background developed my analytical thinking, process-oriented mindset, and approach to solving real-world engineering problems.
Today, I apply that engineering mindset to software development, with a strong focus on Java, Data Structures & Algorithms, Full Stack Development, databases, and secure application development.
I enjoy transforming real-world problems into software products — from healthcare management systems and IoT water monitoring platforms to developer utilities and cybersecurity tools.
I am currently strengthening my knowledge of AI/ML concepts and product engineering to build smarter and more scalable applications.
