// Rust · PostgreSQL · Kubernetes

Fast and secure data systems that simply work.

We design and build software in Rust, monitor PostgreSQL databases, create data processing pipelines and deploy them securely on Kubernetes.

Services

We specialise in areas where performance, reliability and data security matter most.

Rust development

High-performance backend services, CLI tools and libraries — memory-safe, predictable and easy to maintain.

  • tokio
  • axum
  • sqlx
  • gRPC

PostgreSQL monitoring

Database observability: query performance, locks, replication, vacuum and alerting — before problems reach your users.

  • pg_stat_statements
  • Prometheus
  • Grafana

Data processing

ETL/ELT pipelines, stream and batch processing, system integrations and zero-downtime data migrations.

  • ETL
  • streaming
  • Kafka
  • migrations

Security

Code and configuration reviews, infrastructure hardening, secrets management and data access control.

  • audit
  • hardening
  • secrets
  • RBAC

Kubernetes

Cluster deployment and operations, Helm, GitOps, autoscaling and observability for containerised applications and databases.

  • Helm
  • GitOps
  • operators

Have a specific problem?

Slow queries, an unstable cluster, a new Rust service to build — describe the situation and we'll propose a solution.

About

HASH FLUX has been in business since 2022. We do software engineering where data, performance and security meet — from Rust code, through PostgreSQL databases, to infrastructure on Kubernetes.

We favour solutions that are simple to maintain, well documented and measurable — so your team can keep building on them.
