We design and run the server-side foundations of your product: services, data stores, queues and cloud infrastructure, built for correctness first and scale second.
Backend Development
What you receive
Most production incidents trace back to decisions made in the backend: a data model that cannot change, a queue with no retry policy, a service with no way to see what it is doing. We spend our effort on exactly those fundamentals.
We prefer the simplest design that will meet your real load, and we only reach for microservices or event streaming when they solve a problem you actually have. Every system ships with metrics, tracing, runbooks and infrastructure defined as code, so operating it is not a dark art.
Well-structured modular monoliths and microservices with clear boundaries and ownership.
Kafka and queue-based pipelines with idempotency, retries and dead-letter handling designed in.
Schema design, query tuning, read replicas, caching and zero-downtime migrations.
Terraform-managed AWS or Google Cloud, containers, Kubernetes where justified and automated delivery.
Metrics, traces and logs tied to service-level objectives, with alerts that mean something.
Load testing, right-sizing and caching strategies that lower spend without adding risk.
We review code, data, infrastructure and incident history to find the real constraints.
A written design with options, trade-offs and a migration path you can challenge.
Changes ship in small, reversible steps behind flags and traffic-shifting controls.
Service-level objectives, on-call runbooks and training for the team taking ownership.
Tools and platforms
The things founders and leadership teams actually ask us, with honest answers. Anything else, we’re one message away.
Ask your own questionOften not. A well-organised modular monolith is cheaper to run and easier to change for most teams. We recommend splitting services only where independent scaling or team ownership clearly justifies the overhead.
