MD Sojib Hosen

I'm a backend and full-stack developer working in C# and ASP.NET Core, with Angular on the front end. I've been doing this professionally for nearly two years, most recently at Efficient Software Solutions in Dhaka, shipping features for an Irish client organisation across a .NET 6–10 codebase running in Docker and deployed on AWS. Two things I'm proud of. First, I integrated Elasticsearch and moved heavy processing into Hangfire background jobs, which cut search response time by up to 10x and took that load off the core request paths. Second, I delivered a complete CRUD module and an automated email-notification feature end to end — design, build, testing, deployment — and implemented authentication and authorisation across distributed services in a production microservices architecture using CQRS, MediatR, MassTransit, Saga and Outbox. Outside work I built and open-sourced a full-stack platform on .NET 10 and Angular 20: Clean Architecture with a compiler-enforced dependency rule, 198 automated tests (152 unit and 46 integration against a live PostgreSQL instance), and a GitHub Actions pipeline that builds, tests, publishes Docker images and deploys to AWS on every push — github.com/Sojib444. Next I'm looking for a mid-level backend or full-stack role on a product team where I own features end to end and have senior engineers to learn from. .NET is my strongest stack, but the architecture work transfers and I'm happy in whatever the team uses. My last role was remote in practice — daily coordination with people in another country, in English — so writing things down clearly and working async is already how I work. I'm available immediately.
