Experience

Software Engineer II

Jan 2022 - Jun 2022 @ LogDNA (n.k.a. Mezmo)
  • Tackled the refactor of the alerting microservice (send functionality) for integrations with services like OpsGenie, PagerDuty, etc
  • Aided in building a fully fledged provisioning API, spurred by & intended for enterprise b2b use, which aligned with simultaneous RBAC efforts to scaffold a hierarchical organizational structure
  • Worked on our custom Terraform provider/plugin to add support for Slack alerting integration & aligned its resources for consistency with the views/alerts API schema + parity with CRUD operations

Software Engineer I

Jan 2020 - Dec 2021 @ LogDNA (n.k.a. Mezmo)
  • Fulfilled on-call developer duties by debugging culpable code, releasing hot-fixes, rolling back faulty deploys, & pushed for the adoption of a new rotation system to more evenly distribute the workload
  • Advocated for the adoption of RESTful API best practices & standardization across development/documentation by instrumenting Swagger(hub) tooling in alignment with the OpenAPI specification
  • Contributed to efforts involving the migration & upgrade of our system(s) from Elasticsearch version: 5.x -> 7.x entailing the refactor of numerous services/jobs to facilitate the transition from tribe nodes to cross-cluster search & account for changes in the ES API + Query DSL
  • Led development + documentation efforts for the feature release of our Export API v2 allowing users to export their logs as JSON; this leveraged the `search_after` parameter of Elasticsearch's API to provide native support of deep pagination functionality thru queried results
