High-performance back ends for demanding data flows
High-performance back ends & microservices
We build highly available back-end architectures, lean microservices and robust interfaces – for software that stays stable and fast under peak load too.
The problem
When the back end becomes the bottleneck for your growth
Sluggish monoliths slow down the development of new features.
High latency and long response times worsen the user experience.
Missing parallelism and insufficient thread safety strain the servers.
What we do
What we build
Concurrent back-end engineering (Go & Python)
Fast back ends in Go and Python, built for parallel data processing, low memory use and short response times.
Microservices & distributed systems
Decoupled services cut along the domain with domain-driven design – with secure REST, GraphQL or gRPC interfaces.
High-throughput database design
Design and performance tuning of relational and distributed databases – PostgreSQL, Cassandra, MongoDB, OpenSearch – for complex queries with short response times.
From our own workshop
Sleepy Hollow CMS – a headless CMS in Go
This website is served by our own headless CMS: a single Go binary holding the delivery API, the management API and the administration, PostgreSQL as its only dependency and a binding performance budget for the read path. That is how we build for our clients, too.
