About Me
Greetings! I'm Rahmat, a software engineer with six years spent building the unglamorous parts that keep products alive: APIs, queues, schedulers, deploy pipelines and dashboards that tell you the truth at 3am.
My work spans automotive firmware platforms in the UK, AI tooling directories, and process-automation systems in Dhaka. I lean on Java/Spring Boot and Node.js, decouple with Kafka and RabbitMQ, store in PostgreSQL, MongoDB and Redis, and ship through Docker, Kubernetes and Terraform.
I care about observability, clean modular boundaries and pipelines a new teammate can read on day one — plus a little automation wherever a human is doing a robot's job.
