Solid Foundations. Production-Grade Backends.

.NET, Node.js, and Python services built to scale. Authentication, data modelling, queues, background jobs — the unglamorous foundations that make products feel solid and keep them running at 2am without intervention.

  • .NET 8, Node.js & Python
  • PostgreSQL & SQL Server
  • Keycloak & Auth0
  • Background Job Queues
  • OpenTelemetry Observability
  • CI/CD from Day One

What Bad Backends Cost You

Backend problems are invisible until they aren't. By then, they're usually expensive — in downtime, data loss, or emergency engineering.

Authentication bolted on after launch — insecure and hard to extend
No background job system — email sending blocking web requests
Database queries taking seconds because no one designed the schema for reads
No structured logging — debugging production issues requires guesswork
Secrets hardcoded in source control or config files
Background jobs failing silently with no alerting
Data integrity issues because transactions weren't used correctly

What we build instead

Auth from day one

Standards-based authentication designed into the system before any business logic is written.

Async where it belongs

Email, notifications, reports, and other non-synchronous work run in proper job queues — not inline with the request.

Observable by default

Structured logs, distributed traces, and health endpoints so you can diagnose problems in production without SSH access.

Data integrity guaranteed

Proper transaction boundaries, foreign key constraints, and schema migrations so your data stays consistent.

Backend Engineering Capabilities

The full stack of backend services we design and build — foundations that scale with your product.

Service architecture

.NET, Node.js, and Python services — monolith or microservices, designed for your actual load.

Auth & authorisation

Keycloak, Auth0, ASP.NET Identity. RBAC, claims, and audit logging as standard.

Data modelling

PostgreSQL, SQL Server, Redis. Schemas designed for correctness and query performance.

Background jobs & queues

Hangfire, BullMQ, Celery. Retry policies, dead-letter queues, and job monitoring.

Observability

Structured logging (Serilog, Pino), distributed tracing (OpenTelemetry), and health checks.

Testing & CI/CD

Unit, integration, and contract tests. GitHub Actions pipelines so every commit is deployable.
