I’m Misbahul Alam
A Backend Engineer

I'm a Backend Engineer who designs and builds distributed systems in Go — clean API layers, event-driven architectures, and service boundaries that hold up under real production conditions. My focus is on the decisions underneath the code: where consistency boundaries sit, how data flows between services, and what happens when things fail at the worst possible moment. I care about building backends that are not just functional, but reliable enough for the next engineer to read and confidently extend.

System design is where I spend most of my thinking. I apply Domain-Driven Design to define bounded contexts and aggregate boundaries, use the transactional outbox pattern to guarantee event delivery without distributed transactions, and design for failure from the start — idempotent consumers, circuit breakers, dead letter queues. I understand CAP tradeoffs, when to denormalise for query performance, and how a single failing component can cascade into a full system outage if the architecture doesn't account for it.

Technically, I work across REST, GraphQL, and gRPC for service communication — chosen based on the use case, not habit. I build async event pipelines with Kafka and RabbitMQ, work with PostgreSQL across indexing and query planning, and apply Redis caching strategies like cache-aside and write-through with deliberate intent. When I implement something — JWT token rotation with brute-force protection, or a Kafka consumer designed around at-least-once delivery semantics — it's because the problem requires it, not because the pattern sounds good. I containerise with Docker, automate deployments through GitHub Actions, and deploy on AWS.

I'm self-taught and based in Bangladesh, actively working toward my first professional backend role. Every concept I understand I built a genuine mental model for — not memorised, understood. The projects in my portfolio are systems I designed from scratch, made deliberate architectural decisions on, and iterated until they reflected how I actually think. I'm looking for a team where depth of thinking is valued as much as speed of output.
