Sep 2018 - Present
- Extended and transformed Netflix/conductor monolithic service into micro-services implemented using spring-boot.
- Implemented new workflow tasks that are specific to Comcast business needs and collect Comcast business data.
- Extended workflow definition language to add Comcast specific logic and configuration. Workflow DSL allows external implementation of the micro-service orchestration flow.
- Developed framework for micro-services. Activation developers use the framework to implement micro-services that are orchestrated by the workflow service.
- Developed REST API registration service that allows activation platform developers to register REST APIs that are mapped to workflows. Use OpenAPI specification to dynamically create API documentation that allows mobile client developers to auto-generate client libraries.
- Developed test service and test framework for developers to build integration and workflow unit tests.
- Optimized Elasticsearch data loading caching data for bulk updates and indexing.
- Built in resiliency and self-healing logic by pushing exceptions into Dyno queues for re-tries.
- Built custom DataDog metrics to allow process monitoring and building process alerts.
- Built DataDog dashboards for service monitoring and activation implementations monitoring.

Sep 2018 - Jan 2020
- Developed micro-service for integration with Comcast downstream service that is responsible for network devices information. Service provided network topology transforming flat data structures into network graph with gateway and pod extenders vertices.
- Developed micro-service for integrating with Comcast downstream service that is responsible for on-boarding and managing third party network connected devices. Micro-service was traversing through Hypermedia driven REST responses applying business logic. Micro-service was caching hypermedia paths for better performance by reducing inter-service traffic.
Senior Software Engineer
Pinnacle 21

Jun 2017 - Sep 2018
- Developed Java library that enabled dynamic class loading.
- Developed integrations with AWS S3 service for file loading, segment service for application usage metrics collection, and AWS Lambda function integration for dynamic configuration.
- Developed integration with P21 Enterprise server via REST APIs.
- Implemented integration between P21 Enterprise and SAS Life Science Analytics Framework (LSAF) using enterprise capabilities of the CLI application. CLI was imbedded within LSAF. Built data retrieval adapters for tight integration. Resolved connectivity issues related to incomparability of older Java version and enterprise server.
- Built POC application in Scala integrating with AWS CloudSearch service to provide flexible searching capabilities.
