Experiences

Lead Principal Engineer (Cloud & ML Focus)

Oct 2021 - Present
Envestnet, Inc, Remote

Building large scale cloud platforms for financial services and data science initiatives. A combination of AWS cloud and data center infrastructures are included in the architecture allowing for flexible integration between on-prem and cloud services. An automation first attitude pervades this work. Containerized cloud-first technologies ﴾AWS & Kubernetes﴿ to support new initiatives are current focus areas.

Unified Portfolio Accounting (UPA)

UPA is a portfolio accounting platform using bleeding-edge cloud-native technologies for a highly scalable service to maintain, balance, adjust, and validate financial data from custodian platforms and trusted connections to existing platforms like UMP and Tamarac along with our clients. Some resources of the system include EKS with integrations for vEMR (Hadoop), Airflow (MWAA) and custom workflows. This system utilizes containerized microservices managed on a service-mesh deployed from managed CICD pipelines with IaC managed infrastructure.

Small and Medium Business Portal (SMB Portal)

SMB Portal provides a platform to empower businesses to make important decisions more easily and take actions based on data. The integrated portal includes the apps that most SMBs use to run their businesses and provides greater opportunity for growth and partnership between SMBs and banks. The software was implemented with cloud-native containerized microservices which was migrated to AWS managed cloud services as part of a migration. IaC (infra as code) and conversion from on-prem and alternate cloud vendors was a major hurdle to implementation and bringing the product to a managed state.

Data Science Initiatives (DSI)

Multiple internal projects with data engineering and management using a variety of methods including serverless machine learning (Lambda/Step) development and SageMaker with container deployment mechanisms. These projects include finding the data in the enterprise and providing repeatable data feeds which are a considerable challenge. Providing cloud compute platforms for data scientists to do evaluations of the data and promoting as production models continues to be an interesting and difficult process that we are continuously refining.

Data Marketplace

External vendor web-application with internal compute and storage for a data management platform in the financial services space. Integration with the internal system via managed processes and managing security concerns were the primary concerns and issues with implementation.

Principal Data & Analytics Platform Engineer

Apr 2019 - Oct 2021
Blue Cross and Blue Shield of NC, Raleigh-Durham NC (Remote)

Building a data science platform incorporating a data‐warehouse, data‐lake and data‐execution environment using containerized cloud-first technologies ﴾AWS & Kubernetes﴿ to support our mission of data driven decision to provide for a value‐based healthcare approach. A public example includes the media example below:

Cloud-First Platform (AWS)

Built a complete multi-account AWS platform managed via CloudFormation (CF) stacks from the ground up. All aspects of the platform from VPC to IAM/Policy moving towards the higher-level components like shared RDS clusters, EKS clusters, EMR and associated dependent services like S3, ACM PCA, EFS with CSI integration to EKS, Route53 integration with enterprise Infoblox and other services as necessary were all managed via CF stacks. This had overhead but allowed for a highly consistent and managed cross-account environment working together. This implementation included writing Lambda functions and CF Custom Resources for several services when CF did not offer a mechanism to manage a service completely.

Containerized Development (Kubernetes)

Implemented local standardized Kubernetes development with Docker for Windows/Mac and managed AWS EKS Kubernetes cluster per AWS account. Local development initially used docker-compose for deployments to Kubernetes in Docker (KinD) with a migration to Helm3 Charts. The EKS deployments were managed with a shared cross-account CICD Pipeline giving developers full control over build and deployments. Spot-instance CPU & GPU enabled EC2 worker nodes with zero-scaled nodes for GPU to reduce cost allowed for a cost-effective execution platform. The EKS managed Kubernetes and associated AWS resources (EFS/Route53/ACM/VPC/etc) were all managed via CloudFormation stacks (or scripted configuration changes) with synchronized infrastructure deployment environments for development stages. Some of the major inclusions for the K8S clusters were helm chart managed External-DNS, Nginx-Ingress with NLB, Cluster Autoscaler, Nvidia device plugin, Prometheus with resource metrics, KubeWatch and EFS CSI drivers. K8S Service Account (KSA) permissions via AWS IAM Role/Policy at the container level rather than node level offered additional security for managed access to AWS resources. Extensions using AWS Fargate container execution are enabled in a non-HIPAA environment while working out compliance requirements.

Medicare Guided Selling Tool (MGS)

The Plan Finder Tool offers an easy way for members to use their claims data to recommend a plan that best fits their needs. This is for members who are moving from a Blue Cross NC commercial plan to a Blue Cross NC Medicare plan. The public accessible interface for the recommendation engine can be found at MGS Landing. My involvement was to implement the initial recommendations system in May 2019 before our AWS platform was ready for general use. I quickly created a fully integrated and managed Serverless Framework (SLS) implementation using an AWS API-Gateway backed with Lambda functions written in Python3 providing a REST API for WebUI developers which pulled content from a DAX/DynamoDB datastore populated by a custom built containerized event-driven ETL process also written in Python 3.6. This implementation has been live on the above public URL since June 2019 and will be decommissioned 3Q2021 in favor of the new CICD Pipeline and ETL processes implemented in 2Q2020. I have been heavily involved in transitioning the above and building out the cross-account CICD Pipeline (Jenkins) and data engineering tooling (ETL) to support broader development and data engineering practices across the company. As a first-stage developer of a public accessed service, I was in a unique position both as an infrastructure implementer and consumer of both the development and data engineering services the platform team provided to the enterprise.

Drug Lookup and Calculation (DLC)

The DLC project was an investigation into a standard enterprise-wide REST API that would allow for fast drug lookups via sub-strings for ease of search in a web-ui, validation of drug information with parameters, and cost calculations when member details were available to map against plan benefits. The pilot REST API was implemented rapidly as part of the MGST for 2Q2021 deliverables and then made available across the enterprise as the value was broadly recognized.

CarePath (Machine Learning) Models

CarePath is a software framework developed by Blue Cross NC that acts as a deep learning model factory. It constructs state of the art deep neural networks which learn and then recognize the patterns in sequences of claims which eventually lead to particular health events. This enables Blue Cross to accurately identify members at risk for a wide range of preventable events.

We used this in-house general framework to build specific health related models to identify member level risks and possible health impact to focus our care management programs on those members at greatest risk and improve their health outcomes. Production examples of this include:

  • Complex Case Management (CCM) models for predicting both potential hospital initial admissions and a separate readmissions after care using claims and other historical data to target members at risk with the goal of improving health outcomes. These two models have had a measurable impact on member health.
  • Hospital to Home (H2H) model to identify members at high risk for readmission who need support transitioning from inpatient care to their homes.
  • Additional models for Cardiovascular disease, Diabetes

The CCM model was recognized with an Excellence In Service Innovation Award from the International Society of Service Innovation Professionals (ISSIP) and the H2H model with an Innovator Award from Healthcare Innovation.

My role was to validate the framework and models along with assisting is making the code-base production ready. I was also the primary implementer for creating an enterprise production capable platform for the final product. The platform implementation was initially on local laptops and later an AWS EC2 instance. I performed code reviews and changes for the framework source code, individual model data-prep and code, enterprise processes and data management as we moved out of the internal POC. I rewrote sections of the framework and model code to allow migration to scalable cost-effective containerized managed Kubernetes (K8S) deployment using our multi-stage secure cloud-native development platform that provided for a fully self-managed developer experience via a cross-account CICD Pipeline. This allowed for fast cycle times for the development. Further improvements I added included zero-scaled K8S GPU nodes instantiated via resource taint/toleration, scalable and highly available scoring access for the daily public model releases and secure access to managed internal only datastores for the model generation.

Provide expertise in the definition, design, implementation, adoption and adherence to enterprise architecture strategies, processes and standards. This role at AKC was focused on expertise in the Amazon cloud technologies.

Cloud Services and Architecture

Oversee the design and execution of the cloud computing strategy including the cloud adoptions plans, cloud application design, and cloud management and monitoring. Provide expertise in the definition, design, implementation, adoption and adherence to enterprise architecture strategies, processes and standards. This role at AKC is currently focused on expertise in the Amazon cloud technologies.

Rebuild and redesign the primary www.akc.org website to use Amazon Web Services in a rapid migration from a hosted vendor environment. A lack of existing documentation, standards, and procedures for this rapid migration impeded earlier efforts at a seamless transition. No customer impact for the migration I led and completed in a break-neck six week period. A similar exercise for a large consumer transaction website marketplace.akc.org was completed in a period of two weeks with a contracted partner assisting in the effort. Again, done with no customer impact for these transitions.

Reduction in overall website costs from approximately $30,000 USD per month to less than $5,000 USD. Plans for additional reduction in cost to bring total under $3500 per month. Improved uptime, reduced TTFB (time to first byte), and reduced variability of web page responses all contribute to a better user experience. Continued improvements for caching, database optimization and deep application monitoring continue to be implemented for improved user experience.

End-to-end CI/CD implemented for the primary website with additional integration testing frameworks being provided to improve the developer effectiveness and increase the rate of deployments.

Application Modernization from legacy ColdFusion, PERL, and Java application to move to a MEAN development stack and utilize AWS for the new environments. Design and implementation of the new infrastructure proceeds. Varied solutions for the legacy migration include Amazon EMR, ELK log management, ElactiCache, CloudFront, Beanstalk and varied other AWS services. Impediments include a monolithic Oracle database structure and legacy desktop applications accessing the same data in real-time.

Programmer

Build an Amazon EMR implementation for use by the Application Modernization effort. ELK log management for use by individual application monitoring and management.

Evaluate website architecture and develop plans for implementing opcache with php-fpm to accelerate processing of dynamic PHP content. Redis and Memcache implementations are not optimized for short span session content.

Rewrote sections of the PHP based Expression Engine 2.9.3 (CMS) to be fully compliant with PHP 5.6 enabled with warning as errors. Reduced load times on scripts noticeably.

Varnish Caching server implementation requires a re-write of the HTTP session and redirection rules. Current design allow for replay of session actions for invalid responses.

Redirection/Rewrite Rule proliferation includes six locations for a rule to be enacted with the possibility of looping redirections. Building a separation of the rules evaluation with logging into an ELK implementation to assist in understanding the scope of the challenge. Current implementation has over twenty-six thousand (26,000) rules.

Designing a method for domain root flattening that does not include the AWS Route 53 but remains highly available.
