Engineering for regulated, high‑stakes systems where correctness, resilience, and auditability matter.
Our team has delivered software and automation testing for FCA-regulated financial services firms and trading-technology companies. We’ve shipped platforms across payments, trading, risk, and compliance, partnering with product, security, and operations to deliver safely in regulated environments.
Banking‑grade engineering is our default. Strong typing and contracts, deterministic services, and event‑driven patterns keep integrations reliable. We design for idempotency and replay, protect ordering where it matters, and make failure modes explicit so recovery is routine, not heroic.
Scale and reliability are table stakes. We tune for low latency and throughput, apply backpressure thoughtfully, and instrument everything (golden signals, traces, and business KPIs) with SLOs that drive action. We automate non‑functional tests (load, soak, failover, and resiliency) in CI/CD so regressions are caught before production. Change flows through blue/green and canary releases with clear rollback paths and tested runbooks.
Security and compliance are built‑in. Encryption in transit and at rest, least‑privilege access with separation of duties, secrets and key management, audit logs with lineage, and data retention policies that satisfy regulators. Each release ships with auditor‑ready evidence: change history, approvals, segregation‑of‑duties, and test results. We work within PCI‑DSS and SOC 2 controls and align with internal risk frameworks without slowing delivery.
Data is a first‑class concern. We build reliable pipelines covering streaming and batch processing, model ledgers with clear double‑entry flows, and design reconciliation you can trust. Automated checks validate balances, postings, and settlement files; test‑data management and masking keep environments safe and realistic. Where third‑party services are in play, we harden webhooks and retries with idempotency keys and poison‑message handling.
We speak the language of the domain: funding, settlement, exposure, limits, and turn it into clear, testable systems. Acceptance criteria map to business events and risk measures, and regression packs protect what matters so you can move faster with confidence.
