About
I am a software engineer with eight years of professional software development experience across Japan and Bangladesh, including work with Rakuten Inc. and Hitachi, and other prominent companies. I specialize in software architecture and engineering, with hands-on experience across embedded systems, Android, and RESTful API development using .NET, Spring Boot, Finagle/Finatra, and web development with ASP.NET, Azure Cognitive Services, Google Cloud Platform, C, C#, Java, and Scala.
Beyond full-time roles, I have taken on freelance and independent projects, shaping architecture decisions and building prototypes, such as ANAS and resume-tailoring platform prototypes for Job Coach Japan. I love turning complex requirements into scalable backend systems and robust cloud deployments.
