Show moreI am a dedicated Mobile Application Developer with a strong foundation in the IT industry. Currently, I work as a Software Engineer Level-II at Vivasoft Limited, where I contribute to the Mobile App Development team, focusing on creating seamless and innovative user experiences.
Previously, I honed my skills at Rokomari.com, where I specialized in Flutter development and occasionally ventured into Native Android projects. Alongside mobile development, I embraced backend development challenges, gaining hands-on experience with Java, Spring Boot, JSP, and jQuery.
Beyond my professional work, I am passionate about sharing knowledge. As a content creator at Instructory, I teach Android app development, empowering others to grow in this exciting field. I’m also an active contributor to open source projects and have developed several Flutter packages, including the popular Crisp Chat integration.
I hold a Bachelor’s degree in Computer Science & Engineering from Daffodil International University (DIU). Passionate about technology, teamwork, and lifelong learning, I strive to continuously improve and make a meaningful impact through my work and community contributions. Show less
