Kalman Data Filters LLC is a B2B technology consulting firm specialising in cloud infrastructure, platform engineering, and data platforms. We help banks, telecom operators, fintechs, and other enterprises design, build, and operate the infrastructure and data platforms their business runs on.

Four focus areas, plus independent advisory across them.

• Public & Private Cloud Infrastructure — Architecture, design, and deployment across hyperscalers, private data centres, and hybrid estates.
• Platform Engineering — Design, architecture, and implementation of Kubernetes-based internal platforms.
• Data Engineering & Platforms — Data lakes and lakehouses, stream processing, and large-scale databases.
• Tooling & Platforms — Hands-on depth in Kubernetes and its ecosystem, Apache Iceberg, and the open-source data stack.
• Advisory & Assessments — Architecture reviews, roadmaps, vendor evaluations, cost reviews, and technical due diligence.

The open-source and commercial tooling we work with day to day: Kubernetes and the CNCF ecosystem around it, Apache Iceberg and the open lakehouse, streaming platforms, large-scale databases, and infrastructure automation. We choose tools to fit the client’s constraints, not the other way round.

Every engagement runs under a signed service agreement with a defined scope, milestones, and deliverables. Work is delivered remotely by our consultants and, where needed, by independent contractors, and invoiced per project or milestone.
