In his own words, in our voice

The operator who already saw the incident before it happened · twice.

Twenty-year operator inside hyperscaler engineering culture. Built and ran the infrastructure layer at Meta, Dropbox and RobinWood · networks, systems and security engineered to operate at internet scale, under continuous regulatory and adversarial pressure.

Inside Hikari Blue, Gilles carries the Run Practice: the discipline of operating production systems with reliability, observability and audit-ready evidence. He brings to mid-market and enterprise clients the operating standards usually reserved for the companies that carry a meaningful share of the global internet.

Certified at depth on network architecture (Cisco, Enterasys ESE, Juniper, Foundry, Extreme), security (ISS Internet Scanner, Snort IDS, Nessus, Dragon IDS, multiple firewalls) and storage (Compaq StorageWorks for UNIX and Windows, EMC). Fluent across UNIX, Linux, Solaris, Windows, VMS, Mac OS X and the long tail of legacy enterprise stacks most engineers prefer to forget.

His value is not in the certifications. It is in the operating instinct that comes from twenty years on call. The kind of operator who already saw the incident before it happened · twice · and engineered the platform so the third time would be quiet.

Networks fail loudly. Run discipline is what makes them fail safely.

Gilles Mischler · Partner, Run Practice

Inside Hikari Blue

What Gilles carries.

The Run Practice is the layer where production systems live, fail, recover and improve. Gilles is the named partner accountable for reliability, on-call ergonomics, security posture and the audit trail that makes the run defensible to regulators and to the board.

  • Reliability engineering · SLOs, error budgets, incident discipline, learning loops.
  • Observability and on-call uplift · humane rotations, real runbooks, alert hygiene.
  • Network and security architecture · supply-chain provenance, defense in depth, kill switch.
  • FinOps and run cost optimization · decomposed cloud bill, decommissioning of idle, monthly cadence.
