As an engineer at VoiceFoundry, my role is to be the backbone of project delivery, as well as provide guidance to our clients on training & best practices. I work to refine the process of project delivery by building internal tools, suggest new methods of designing & building a system, & provide feedback to my team leads on issues. Additionally, I provide guidance to team members on industry best practices during code reviews.Operate within the agile software development methodologyManage sprint life cycle using JIRAAmazon Connect- Setup & configure instances of Connect based on requirements- Integrate custom logic using lambda functions- Engineer contact flows based on designs- Custom CCP built with ReactAdmin App- Custom off-hours & holiday messaging for contact flows- Support multi-language contact flows with dynamic prompts- Maintain & deploy infrastructure resources with SAM- Capture prompts & hours info in an Angular UI- Process server logic with Python lambdas- Store data in DynamoDB for retrieval from Connect- Encrypt resources at rest using KMSVoicemail App- Leave voicemails for a queue or individual agent- Maintain & deploy infrastructure resources with Serverless- Invoke Kinesis to capture audio shards in contact flows- Store .wav files in S3- Store recording metadata in DynamoDB- Process server logic with Typescript (Node.js) lambdas- Build UI with Angular- Encrypt resources at rest using KMS- Set time-to-live on audio recordings per client requirementsStorage App- Export Connect data using Kinesis & Firehose to S3 for custom reporting & analysis- Maintain & deploy infrastructure resources with AWS CDK- Encrypt resources at rest using KMS

Using the Agile methodology, I contributed to a federal sector project. As a full stack JavaScript developer, I was the sole contributor to an enterprise level analytics dashboard with custom charts created using D3.js, wrapped in Angular, and Git for version control. In addition to front end work, I built and maintained the back end using several node servers with MongoDB as the database mechanism. This application was designed with a micro-services architecture, containerized using Docker, and was planned for deployment to AWS within a DI2E environment.I delivered quality assurance by implementing automated tests using Mocha.js and Chai.js, integrating into our CI/CD pipeline (Jenkins). These tests ensured accurate delivery, eliminated unexpected bugs and failures, and reduced team resources spent on QA.Sprint planning, issue management, and retrospectives were conducted via JIRA.
