High-Load Data Architecture & API System Design
Storage and interface design for systems where volume, latency or contract stability have stopped being somebody else's problem.
What this actually means
Throughput problems are usually modelling problems wearing a costume. We look at access patterns before technology: what is read, how often, by whom, and what has to be consistent with what. From that comes a storage design, an indexing and partitioning strategy, a caching layer that can be invalidated correctly, and an API contract that can be versioned without breaking every client. Where the honest answer is that your current database is fine and the query is wrong, that is the answer you get.
What you get
- Access-pattern analysis and a data model that follows from it
- Indexing, partitioning and retention strategy with the trade-offs written down
- Versioned API contract — OpenAPI or schema-first — plus a deprecation policy
- Caching and queueing design with explicit invalidation and back-pressure behaviour
- Load model and a repeatable performance test, so the next change can be measured
What this does not cover
- We publish no throughput or latency figures for past work. Numbers without your workload behind them are marketing, not engineering.
- We do not sell or license any database, analytics or observability product.
We publish exclusions beside every service on purpose. A supplier who describes only what they do leaves you to discover the boundary during the engagement, which is the expensive time to find it.
Typical technology
- PostgreSQL
- MySQL
- ClickHouse
- Redis
- Kafka
- OpenAPI
- gRPC
- Elasticsearch
- dbt
- Airflow
Indicative, not prescriptive. The right stack follows the constraints; a list like this one is a starting point for a conversation, not a commitment either side has made.
How it is engaged
Design engagement, or a focused intervention on a system already under pressure.
No price appears here or anywhere else on this site. Cost follows scope, and scope follows the reading we do at the start.
