Available to hire
I’m Sakhawat Hossain, a Senior Software Engineer focused on building scalable mobile and cross-platform systems with Kotlin, Jetpack Compose, and Flutter. I’ve led mobile architecture across in-house and client products, created agentic development pipelines that turn Jira tickets into implementation plans and code, and helped teams adopt safe review/verification gates so agent-generated code meets the same quality bar as human work.
