Speaking

On this blog, I write and speak about how to understand, govern, and transform complex digital systems. Not a buzzword checklist.

Topics

Topics documented here. Each talk adapts to context, audience, and format, with no default fixed duration.

Building a living map of the information system

Problem addressed
Organizations decide on frozen diagrams or incomplete inventories; no one shares the same representation of the system.
Audience
CTOs, architects, platform and security leads
Three takeaways
  • A useful map serves a decision, not another dashboard.
  • Code, cloud, runtime, and supply chain must be read together.
  • Mapping is a continuous process, not a one-off deliverable.

SBOM as a decision tool, not a compliance checkbox

Problem addressed
SBOMs are produced for audits but rarely used to prioritize risk or arbitrate updates.
Audience
CISOs, supply chain leads, platform and SRE leads
Three takeaways
  • Connect the SBOM to patch and deployment decisions.
  • Distinguish real risk, exposure surface, and regulatory obligation.
  • Integrate SBOM into the delivery cycle, not at the end of the chain.

Why fifty thousand alerts do not make a system safer

Problem addressed
Observability is confused with signal volume; teams drown in alerts without reducing risk.
Audience
SREs, observability leads, engineering managers
Three takeaways
  • Measure ability to act, not the number of triggered rules.
  • Connect signals, runbooks, and capacity decisions.
  • OpenTelemetry as a common language, not a tool catalog.

Platform engineering: reducing cognitive load without new bureaucracy

Problem addressed
Internal Developer Platforms become rigid single windows instead of simplifying the path to production.
Audience
Platform engineers, CTOs, product and infrastructure leads
Three takeaways
  • Define the platform product by removed frictions, not by the stack.
  • Golden paths yes, blind enforcement no.
  • Measure adoption by accelerated decisions, not catalogued service count.

Designing digital products for constrained markets

Problem addressed
Products designed for a global market fail against local regulatory, cultural, and infrastructure constraints.
Audience
Founders, product leads, investors, and institutional partners
Three takeaways
  • Constraint filters design; it is not a planning delay.
  • Architecture, compliance, and go-to-market must be co-designed.
  • Traction proof comes from accessible products, not slides.

External dependencies: what Kubernetes does not show you

Problem addressed
Workloads depend on off-cluster services; the control plane neither maps their health nor their SLO impact.
Audience
SREs, platform engineers, cloud-native architects
Three takeaways
  • Export comparable signals for external dependencies.
  • Connect automatic discovery and actionable runbooks.
  • Do not confuse pod availability and business service availability.

Architecture, risk, and irreversible decisions

Problem addressed
Architecture choices are treated as reversible when they commit cost, security, and product trajectory for years.
Audience
CTOs, CISOs, enterprise architects, and technical steering committees
Three takeaways
  • Classify decisions by rollback cost, not hype cycle.
  • Document context and rejected alternatives.
  • Connect architecture decision records and operational governance.
