WORK EXPERIENCE

Hivebrite – Staff Site Reliability Engineer (March 2024 - Today)

Drove cross-team initiatives to improve reliability, scalability and developer productivity across a multi-tenant SaaS platform. Built internal tools to automate infrastructure and incident workflows, defined standards for CI/CD and mentored engineers across the organization.

CI/CD & Infrastructure

  • Deployed self-hosted GitHub Actions runners on GKE with autoscaling.
  • Designed and operated Terraflow, an internal CI/CD orchestrator for Terraform to reduce deployment toil and prevent infrastructure drift. (article)
  • Migrated legacy Buildkite pipelines to GitHub Workflows for faster, more reliable builds.
  • Added automated security and quality checks using pre-commit hooks across all repositories.
  • Integrated Temporal for workflow orchestration and Qdrant as the vector database for the content-recommendation service.
  • Leading AI tooling transition within the team, training, Cursor rules creation and AI pull request review tool comparison (Cursor Bugbot vs Claude Code vs Graphite Diamond)
  • Led AI tooling transition within the team and participated in AI PR review comparison (Cursor Bugbot vs Claude Code vs Graphite Diamond).

Reliability & Observability

  • Redefined cross-team incident management workflows to improve runbook and postmortem quality and enhance production support and on-call experience.
  • Migrated the Istio Operator to Helm-based Istio deployments to eliminate downtime, simplify upgrades and reduce tech debt.
  • Created an agentic Slack Incident Response Bot to automate Datadog monitors and vendor status updates while integrating with Claude Code and MCP servers to retrieve related incidents, recovery steps and documentation.
  • Led observability platform comparison across Datadog, Grafana Cloud, Coralogix, Signoz and self-hosted with OSS.

Performance & Optimization

  • Drove the Ruby on Rails webserver migration from Puma to Falcon, performing benchmarks to achieve ~36% lower latency, ~67% higher throughput and ~86% fewer 5xx responses with flat memory usage. Trade-off: ~58% more CPU usage.

Leadership & Org Impact

  • Helped on cross-team initiatives, contributing to architecture reviews and engineering roadmap.
  • Founded the company Engineering Blog and established publishing standards.
  • Mentored engineers through pairing sessions and internal technical workshops.
  • Terraflow recognized in Hivebrite’s Crédit Impôt Recherche & Innovation 2024.
