Migrated encrypted secrets from Ansible git repository to AWS ParameterStore
Maintained and performed maintenance on AWS EKS clusters across environments
Authored reusable and composable Terraform modules and published them to the company internal registry.

2017 - 2021: Senior Devops Engineer - Nomis Solutions

Wrote Names API, a Golang microservice designed to automatically generate standardize tags, DNS records, and Terraform resource names
Automated deployment of applications using Terraform, Python, Fabric and Docker
Automated infrastructure provisioning with Terraform, including fully operational replicating MongoDB clusters, as part of a MEAN stack.
Overhauled the manually maintained monitoring system from Nagios XI to Datadog.
Wrote services-scaler, a Python microservice designed to control the size of auto scaling workers based on RabbitMQ queue length.
Wrote NomisPy, a generic and reusable Python library for internal organization purposes.

2015 - 2017: Senior Infrastructure Engineer– Forever, Inc

Wrote datamon - a Python daemon that monitors the production Postgres instance, system metrics, and log entries to spot potential database issues.
Wrote qwatch, a Golang daemon that monitors AWS SQS queues and ships high resolution metrics to Librato.
Wrote Provisioner - a cross-platform bootstrapping program designed to provision Windows / Linux machines with packages, and execute the initial configuration management run.
Expeditiously tracked down root causes for production issues. Vigilant about triaging, fixing, and escalating off-hour alerts.
Performed database migrations and upgrades at the lowest traffic times to ensure little-to-no customer impacting downtime.
Was solely responsible for designing, maintaining, and monitoring the infrastructure at all times.

2013 - 2015: DevOps Engineer– BrandingBrand

Wrote MISHAP - a Golang daemon that reads application routing information from redis and writes HAProxy configuration. It provides real-time (1s resolution) routing of moving, containerized applications on cloud hosts with no dropped connections.
Wrote Dockermon - a Python monitoring / stat-collecting daemon for Docker that ships per-container metrics to Riemann and Graphite.
Built and architected the Marathon / Mesos / Zookeeper fault-tolerant infrastructure. Maintained and monitored the infrastructure and performed many zero-downtime upgrades on the production environment using the blue / green deployment approach.
Wrote commands and plugins for the internal developer CLI tool to simplify the development process. One of such tools, “stage-me”, provides a method for a developer to spin up an entire environment for an application with a single command (not unlike Heroku push).
Rewrote all of the existing infrastructure cookbooks, stripping out cruft and decreasing the total system provisioning time from 40 minutes down to 5.
Well-versed in configuration management software and source control (Chef, puppet, git, etc).

Developed scripts, services, and tools to control, monitor, configure, and manage a hybrid physical / cloud infrastructure.
Visualized data through Graphite to trace down hard to find issues and correlated trends across the network.
Experienced in building (physical and virtual) boxes and provisioning them with custom images via PXE.
Extremely comfortable managing and maintaining a wide variety of differing servers, equipment, and systems in the on-site datacenter
