Tech Stack: Node.js, GraphQL, Typescript, Postgres, Redis, MongoDB, Elastic, RabbitMQ, Kubernetes, and Terraform.

- Developed multiple microservices with Node.js using Koa, and a wide range of other technologies, like Elastic Search, Redis, Postgres, and MongoDB.

- Created the Company's own monitoring/logging solution, using a self-hosted Elastic stack, Prometheus, Alertmanager, Grafana, and other related tools. To monitor, alert, and act on problems before, during, and after they happen.

- Moved from an external SaaS ElasticSearch provider to use the company's existing infrastructure to host their own ElasticSearch cluster, reducing costs and improving general performance.

- Migrated company infra from a dashboard centric management (using Google Cloud Console) to use Infrastructure as Code (IaC) with Terraform, this enabled better tracking and ownership of changes and provided a faster development workflow. Scaling a Kubernetes cluster became as simple as changing a number and running a command.

- Rewrote the scripts used to deploy projects to the Company's Kubernetes clusters [1] allowing more customizations at a project level by using the Kustomize CLI tool.

- Built the backend and supporting infrastructure for a new React Native mobile app using Node.js, GraphQL, SocketCluster, Redis, and Postgres.

- Migrated a dozen of Koa.js REST microservices to a single GraphQL monolith, used Elastic APM to trace performance issues during the migration. This made API requests ~127% faster in some parts of the application.
