Streamlined EKS scaling with Karpenter reconfiguration and upgrades, making the clusters far more efficient and agile.Drove conversations and ideas to reduce Kubernetes administration burden and simplify cluster upgrades that saves days of engineering hours per upgrade.

Designed dynamically generated Gitlab pipelines to support our mono repos through the use of existing tooling as well as custom tooling. This design also sped up CI/CD pipelines by 6x, and the dynamically generated pipelines determine what child pipelines and jobs to run.Built tooling to automate workflows and deployments, for example pausing and resuming Gitlab Runners when deploying upgrades to the underlying Kubernetes clusters hosting the Gitlab Runners.Led efforts to stabilize Terraform deployments, deploy a Hashicorp Vault cluster to ECS and migrate secrets to it, migrate workloads from VMs to containers and build an internal developer platform.Built RFCs and proposals for design shifts and new services.Trained and mentored other SREs and engineers to advance the collective reliability and velocity of our teams.

* Investigated performance and stability issues in distributed systems, and resolved them.

Designed a new platform on top of EKS despite being the only person in this role and area of responsibility, and regularly given new responsibilities to maintain services outside our team.Successfully migrated services from a custom Kubernetes cluster into a new account and onto this new platform. This involved coordinating with multiple infrastructure and cloud teams to build the appropriate AWS accounts, routes, DNS zones, global networking, etc. as well as pinpoint issues to guide these teams to a resolution and work around the issues until they could resolve.Built custom tooling for IAC, and automation of maintenance/repairs of brittle systems; e.g. upload generated K8s certs to AWS ACM, automate annotation of auto-gen’d K8s certs so that Istio ingress controller would utilize them, mirror DNS records across accounts to mitigate zone forwarding flakiness, implemented a stable migration process on our own when faced with unstable Artifactory migration process where JFrog was unable to assist; fixed and prevented future disaster causes by expiration of enterprise’s Vault cluster’s internal certificates...Integrated complex systems and services through non-standard means when necessary.

Redesigned and replaced existing custom core deployment tools developed by the team when they had minimal manpower. The new tool was reliable, shifted requirement checks to the start rather than dispersed across the run, provided robust feedback to guide users, cleaned up all known bugs in the previous deployment tool, and provided new features to fill rising needs of the user base.Seized the opportunity to improve automatic network fail-back which must only be executed within specific company requirements. Fail-over was previously automated by another teammate. :)Advocated and persuaded everyone I could to invest in building self-healing, resilient systems to reduce the regular toil and concern the team endured.

To move towards disaster recovery, gradually implemented infrastructure as code for (de)provisioning and (re)configuring all cloud resources--VMs, kubernetes clusters, networks, etc.Developed custom tooling to accomplish the above mentioned projects, which involved much interaction with cloud APIs and some use of Terraform--similar to today’s Terraform CDK.To facilitate centralized management of company services, like printing across all remote offices, connected all remote office networks to a cloud network in a hub-spoke configuration using the above infrastructure as code implementation.

To facilitate team & service agility, developed tooling with NodeJS ES6 that configured & deployed Kubernetes resources including: a custom ingress controller with an optional, custom WAF to block access to any host or URI desired including company microservices, Atlassian suite (Jira, Confluence, BitBucket, Bamboo), and more.To bring automation into “everything”, architected & developed a robust, immutable automation platform that provided more than a standard DevOps pipeline. This utilized proprietary code along with Jenkins & Kubernetes, all of which were controlled by source code with standards enforcement and safety checks. Developers could run a local copy of this automation platform to test their workflow and pipeline changes. This was all done before JSX was announced.To increase service reliability & deployment frequency, moved software deployments from virtual machines to immutable container deployments inside Kubernetes with rolling releases, health checking, load balancing, auto-scaling, self-healing and rollback through all environments.

Served as backend web developer utilizing Node.JS to produce RESTful APIs and more...Designed and maintained a custom, encrypted desktop developer environment VM. This ensured each team member had the same tools available to them, and their microservices were locally run in a manner that mimicked production. This removed, “it works on my machine” conversations. Environment was self-healing and performant, and automated away tedium for the developers.

Developed DevOps automation programs for deployment and maintenance of critical systems.Assist the team in implementing newer technology and coding practices in DevOps Automation starting with detailed discussions with architects, team leaders, and teammates on current issues, design & implementation goals, and desired features list; then correlating the information into useful, clear documentation and implementing code changes and additions.Translate acquired knowledge from teammates and leaders into beneficial documentation for the team.Build and manage Linux and Unix internal servers.Handle tier 4 escalations and participate in an on-call rotation that include deep interaction with technologies such as PXE, TFTP, DHCP, LDAP, NAS, Big Data, MySQL and other database engines, Apache and other web services, etc.Day to day work involves prioritizing and multi-tasking; whilst working mostly with ruby, gems, scripting, DevOps, and similar.

Resolved customer system issues with either their workstations or servers or network.Taught customers important skills on their systems.

Cut costs by 50% in collocation & power by restructuring company resources, migrating hardware to virtual servers & repurposing hardware, and negotiating new contracts.Developed tech for a multi-million dollar video email entity, including HA of legacy software, effective layered security, media transcoding & array of consumer device compatibility.Deployed & maintained Linux & Unix machines with DevOps automation – Chef, Shell Script, etc.Hardened security of potential or client-in-use technologies, involving Linux kernel modifications, firewall changes, attack detection and prevention code updates, restructuring components, etc.

Built enterprise-level software with many of the above listed skills in each project, including:* HIPAA compliant, Medical Practice Management Solution for a multi-million dollar entity; built using C#, JavaScript, etc. client technologies and Unix server technologies.* Custom built, SEO optimized e-commerce site which maintained page one search results in a competitive market, effecting a 200% increase in revenue.Built internal tools for increased productivity.

Remote technician for clients across the nation.Maintained a professional conduct and tone with difficult customers.Held tight to company policies and procedures.Volunteered for tasks outside what was expected.

Built utility applications for company and clientele to automate tasks, remove corrupt emails, correct faulted web browser installations, etc.Constructed, administrated & repaired company servers.Efficiently repaired clientele computer software and hardware.Designed the company’s website with potential buyers and ease of use in mind.Managed company projects with problem-solving mentality.
