Private / Public Cloud Solution Architect

Designed an Azure based infrastructure for a Managing Director. The business requirements included an SSO SAML authentication for internal and external clients utilizing Azure AD B2B. Designed front end load balancing web farm and protected backend data sources by splitting it out to a different subnet and creating Network Security Groups. Drafted detailed topology diagram that showed Azure Site Recovery mechanism for BCP plans and documented the firewall rules that needed to allow Azure Site Recovery through to the Internet connections. Worked closely with various individuals across multiple disciplines to get a coherent architecture. Suggested solutions on supported an LDAP lookup of AD users via Restful API calls. Assisted the SQL team on the design of the SQL Always On cluster in Azure with a File Share Witness, and a Backup Strategy.

Exposure to Route53 using Ruby or Golang to manipulate and manage CD CI pipelines for DNS records.

To reach tiering rating of 2 or higher, I wrote BCP automation c# code integrated with on prem Microsoft Azure Service Fabric. The code was designed to test availability of SQL database by means of a SQL Always On Listener. If the database became unavailable, the code would retry several times based on the configuration, then would proceed to failover the database and setup surviving nodes as primary and synchronized secondary.

Automate Azure Infrastructure buildout via .NET native Azure Management libraries to standup cloud infrastructure rapidly.

Designed a geo replicated Redis cache cluster where the end client had a need to replicate the database cross region. There was a business requirement to have an active / active configuration. We utilized Global Traffic Managers and Local Traffic Managers.

Utilize Azure objects such as SQL database with Geo-Replication, Key Vault for data at rest encryption, Blob storage for SQL File Share Witness, NAS based services for both SMB and NFS based storage, Service Fabric, Docker Containers, and Cosmo DB.

Architected a Mongo DB Infrastructure with data partitioning, routing, backup / restore and BCP in mind.

Managed developers and UI designers to create a web portal to gather infrastructure business requirements. The web portal dynamically changed based on FSS of the Tax Channel and would tailor business requirement gathering to the specific FSS to capture nuances that are different per FSS.

Wrote a WPF XAML based UI front end to create a configuration file for the SQL automation code. It uses data binding and is based on an MVVM model to abstract the underlying data object from the UI component manipulation.

Research in containerization models for managing platform microservices in a service fabric environment for resiliency, controlled change management, rollback of services if the change is not deemed fit for the environment.

Designed a resilient File Services offering to provide High Availability and replication.

Diagram application data flows to have Architecture Reviews and submittal for infrastructure procurement so that firewall rules, infrastructure, and data storage all meet business requirements.

The key architectural components were utilizing Secure Server and Azure Key Vault. The process also included an ITIL RACI model to define roles and responsibilities to ensure there were correct separation of duties and a clear strategy behind managing key based data encryption.

Create work flows to introduce structure into business processes such as the beginning of a project initiatives, gathering business requirements, engaging in a POC, architecting a design, cost estimation, BCP planning / gap analysis, architectural reviews with architecture review boards, to engaging PMOs with a project.

Conducted review of BCP procedures and drove project to meet business requirements such as reviewing database snapshot frequency, data replication (SAN based vs application based), DNS failover, application level consistency which included message bus state. Meet with architecture review boards to certify BCP plans for applications to ensure applications can meet the business' expected RPO / RTO.
