Spark jobs too slow or unstable. AI training stuck behind storage. Production incidents repeating. The data platform is now the bottleneck.
Cloud or private-cloud bills growing. Storage and compute capacity decisions made without confidence. Vendor proposals hard to challenge internally.
A migration, a re-platforming, a new architecture choice. Internal teams have a view; an independent expert read can de-risk months of work.
€250 HT / 1h
A focused video session to unblock one architecture, performance, scalability or cost issue.
From €4,500 HT
A focused review of one critical decision, bottleneck or system component — or a sizing engagement for a new deployment or capacity uplift.
From €7,500 HT
Deeper audit for complex data, cloud or AI platforms where performance, reliability or cost has business impact.
From €3,000 HT / mo
Ongoing senior guidance for teams operating complex data infrastructure.
Notes from production data infrastructure work — Spark, MinIO, Ceph, Kubernetes, AI training pipelines.
A 30-min scoping call is free. We’ll determine fit, urgency and rough budget.
Two MinIO platforms, same root cause: used as a NoSQL store. Field notes on LIST IOPS, XFS directory limits, scanner & heal SLAs, the erasure-coding storage-efficiency inversion on small objects, and why Apache Cassandra (or Ceph) is the right answer on-prem in 2026.
Note: This article was inspired by a LinkedIn post by Can Sinan A. on the hidden operational cost of an Iceberg migration, especially when governance moves from one access-control plane to several layers: catalog, storage Read more
When Tesla published patent WO2024073080 describing a new file format internally called “.smol”, the headline was simple: 4x reduction in IOPS for AI training. Most people read this as a hardware story. It isn’t. It’s Read more
