Data Monetization for Fintech

Selling financial data means becoming a regulated data supplier. Permissible purpose decides what you can sell, and the compliance obligations are the real cost.

Insights ·

FinOps Guardrails for Energy

Energy workloads carry long-lived data and heavy compute. Make budgets and retention platform primitives enforced at provisioning, so cost is a design decision rather than an annual surprise.

API Gateway Strategy in the Agent Era for Fintech

Agent traffic breaks rate limits built for humans and stresses idempotency on payment APIs. Separate north-south, east-west, and agent paths, and make every retry safe.

Apache Iceberg for Energy

Iceberg suits energy because time-series data gets corrected for years. Snapshots and schema evolution matter more here than in most estates, and so does compaction.

Insights ·

Data Products for Energy

In energy, a data product needs an owner, a contract, and a stated position on gaps. Time-series data with silent holes is worse than data that admits what it does not know.

Insights ·

AI Agents for Infrastructure for Energy

Agents that act on infrastructure are arriving in energy engineering. What makes them safe near regulated and operational systems is scope, permissions, and a blast-radius budget, not model quality.

IDP Build vs Buy for Technology & SaaS

Buying a developer platform does not remove the work, it moves it. The integration, golden paths, and ownership are yours either way. Budget for the part nobody puts on the slide.

Runbook Automation for Fintech

In fintech a runbook step can move money. Write the procedure, prove it manually, automate the read-only diagnostics, and keep segregation of duties intact in the automation itself.

Developer Experience Metrics for Technology & SaaS

Telemetry tells you what happened; surveys tell you what it felt like. Measure both, never rank teams with them, and watch the friction metrics that actually predict retention.

Delta Lake vs Iceberg for Technology & SaaS

Delta, Iceberg, and Hudi solve the same problem. Choose on engine landscape and who you want to be coupled to, because the feature gaps close and the coupling does not.

Zero-ETL for Technology & SaaS

Zero-ETL removes the extract and load, not the transformation. The modelling work moves somewhere else, and coupling your warehouse to production schemas has a cost.
