What I'm looking for

I seek a dynamic work environment that fosters growth and innovation.

I'm Mohammad Khalid Hasan, a dedicated software engineer with a strong foundation in backend development and a passion for creating scalable applications. Currently, I work at Bangladesh Japan Information Technology (BJIT), where I collaborate with clients to gather and analyze business requirements, ensuring that the solutions we develop meet their needs effectively. My experience includes designing and developing applications using RESTful APIs and MVC web architecture, as well as maintaining reusable libraries and modules.

Throughout my career, I have gained hands-on experience in various technologies, including Java, Spring Boot, and MySQL. I have successfully implemented authentication and authorization modules, designed RESTful APIs, and contributed to multiple projects, such as the Health Care Management System and the Mail Service Reusable Library. My commitment to clean coding principles and design patterns has allowed me to deliver maintainable and efficient code, while my collaborative approach ensures successful project delivery in cross-functional teams.
