about

I design, build, and operate privacy‑respecting systems for teams that value reliability and clear ownership. My roots are in data centers and networking, and my day‑to‑day spans backend services, ingress, storage, and the automation that ties it all together.

I like boring, proven solutions that are easy to reason about and economical to run. Small, composable services with explicit contracts; minimal state at the edge; clean failure modes; and the kind of observability that helps you debug at 03:00 without guesswork.

Typical engagements start at the whiteboard and end with a pager that does not ring. I document the shape of the system, set SLOs, wire metrics, logs, and traces, write runbooks, and practice disaster recovery. When incidents happen, we get a timeline, fixes, and learning, not blame.

Tools I reach for: Linux, containers, nginx, PostgreSQL, Redis, and object storage. Infrastructure as code with Terraform and Ansible when it fits. CI pipelines that build once and promote. Secrets managed centrally. Networking kept simple and auditable.

I keep a strict privacy stance. I collect no unnecessary data, I default to encryption, and I reduce metadata wherever possible. I prefer open source and publish small utilities that give users control.

I choose to remain anonymous for client safety and my own threat model. Many of the systems I work on are sensitive, and NDAs apply. If we work together, the deliverables and results speak for themselves.

experience

consulting (recent)

  • Designed privacy‑first services with strict trust boundaries.
  • Hardened ingress with mTLS, rate‑limits, and header policies.
  • Built defensible observability: logs, traces, metrics with data minimization.

operations (on‑prem)

  • Managed racks, hypervisors, storage, and network fabrics.
  • Implemented backup/restore and DR across facilities.
  • Automated provisioning and repeatable rollouts.

cloud architecture

  • Bridged on‑prem to cloud with secure peering.
  • Built containerized platforms with CI/CD and policy guardrails.
  • Optimized cost without sacrificing reliability.

security & privacy

  • Threat modeling and hardening for public‑facing systems.
  • Client‑side crypto designs; secret and key management.
  • Privacy‑by‑default patterns; metadata reduction.
$ notes
Anonymous by design. Client work is under NDA and not listed.
Public releases focus on tools that improve privacy and control.
