Services
Senior engineering for systems that must stay correct, fast and available, from the first architecture sketch to production hardening.
Most engagements touch more than one of the areas below. An event-driven platform has to be fast, it has to survive partial failure, and it has to be secure, so we treat these as facets of one discipline rather than separate offerings.
Whatever the scope, the work is done by senior engineers, in Rust wherever it is the right tool, with design decisions written down and failure paths tested as carefully as the happy path.
-
01
Distributed systems
Architecture and implementation of systems that span machines, regions and failure domains, with guarantees you can actually write down.
Details- Architecture and design reviews
- Consistency and replication strategy
- Consensus and coordination: Raft, leases, fencing
- Partitioning, sharding and rebalancing
- Ledger and blockchain infrastructure
-
02
Event-driven architecture
Event streams, message brokers and event-sourced systems that deliver every message the number of times you intend, in the order you need.
Details- Event modelling and schema design
- Event sourcing and CQRS
- Kafka, NATS, Redpanda and similar brokers
- Transactional outbox and idempotent consumers
- Schema evolution, replay and backfills
-
03
High-performance systems
Low-latency, high-throughput services engineered from measurements, with attention to the tail and not just the average.
Details- Profiling and performance audits
- Tail-latency (p99, p99.9) reduction
- Async runtimes, concurrency and lock contention
- Memory layout, allocation and zero-copy I/O
- Benchmarks and regression tracking in CI
-
04
Resilience & error handling
Systems that expect failure, contain it and recover, with error handling that is explicit, typed and tested.
Details- Error-handling architecture and review
- Timeouts, deadlines, retries with backoff and jitter
- Circuit breakers, bulkheads and load shedding
- Graceful degradation and fast recovery
- Fault injection, fuzzing and game days
-
05
Security engineering
Security built into the architecture and the code: memory safety, least privilege, and a software supply chain you can account for.
Details- Threat modelling and secure design review
- Security-focused review of Rust code, including unsafe and FFI
- Supply chain: cargo-audit, cargo-deny, cargo-vet, SBOMs
- Authentication, authorisation and secrets management
- Fuzzing and undefined-behaviour checks with Miri
