About

A small studio
built around judgement.

01 · Why

Writing software has never been easier. Running it well has never been harder.

8bar exists for the work that doesn’t get cheaper just because code does — the architecture decision that has to be right the first time, the platform that has to survive its own success, the codebase that has to be inherited and improved instead of torn down, the product that has to ship under a real deadline with real users on the other side.

We take on a small number of engagements at a time and treat each one like our own product.


02 · How we work

Every engagement is scoped before it starts. We agree on the shape of the problem, the artifacts you’ll get, and the timeline — in writing — before any code is written.

  • Decisions you can refer back to.
    Architecture documents, audit reports, runbooks. Written so the next engineer — yours or ours — picks up where we left off.
  • Production-grade defaults.
    Tests, observability, and CI from day one. The dividing line between code that ships and code that runs.
  • Direct access to the engineer making the decisions.
    No account layer, no offshore handoff, no chatbot in the loop where judgement should be.

We don’t do open-ended staff augmentation, body-shop placements, or prototypes dressed up as production systems.


03 · Areas of expertise

The domains we’ve spent the last decade in — and the ones we’re fluent enough in to make good calls quickly.

  • Payments & FX.
    Multi-currency accounts, payment-processor integrations, settlement, and reconciliation flows.
  • Trading & market infrastructure.
    Order flow, RFQ negotiation, settlement engines, real-time risk and position management.
  • High-throughput mobile platforms.
    Backend infrastructure for consumer apps operating at hundreds of thousands of requests per minute.
  • Event-driven architectures.
    Kafka-based systems for real-time data flow between services and across organisations.
  • Cloud platforms & migrations.
    Kubernetes estates on AWS and Azure; gateway, ingress, and identity migrations on live production systems.
  • Observability & SRE.
    Prometheus / Grafana stacks, alerting, on-call rotation design, incident response and post-mortem practice.
