EXPERIENCE

RevApps | Software Engineer

Mar 2024 - Present

Remote, USA

  • Engineered an ML driven text analysis system using AWS Bedrock, integrating a Foundation Model (FM) with AWS Lambda and DynamoDB to process and analyze data in a serverless architecture, delivering real-time sentiment analysis for executive teams
  • Spearheaded the initial POC to create a RAG solution for specific knowledge based research, creating AWS Lambda functions with Python and LangChain, orchestrating text splitting from documents to upsert vector data into PostgreSQL with pgvector
  • Created the localized and globally Distributed Presence Awareness Engine, leveraging MQTT5 with LWT strategies to monitor multiple User Presence Types in real time on top of AWS IoT Core with WSS, scaling to millions of concurrent DAUs elastically
  • Created the ECS Fargate Autoscaling Group with AWS CDK v2, using Typescript to configure the Infrastructure as Code, measuring against CPU utilization for scale out/ scale in functionality with configurability across multiple deployment environments
  • Leveraged AWS EventBridge to orchestrate the Email Management Platform, connecting to ECS Fargate for ingesting user metadata and triggering AWS Lambda to connect to SES with Typescript on Node.js, improving the account management to reduce churn by 18%
  • Architected the Customer Engagement Microservice from scratch, leveraging AWS CDK v2 to construct an entire serverless API layer with API Gateway, AWS Lambda with Python and leveraging the boto3 library to persist interaction data in DynamoDB
  • Achieved over 92% testing coverage with our core Jest Typescript testing suite, integrating CI/CD utilizing AWS Codepipeline
  • Improved user conversion and product growth by revamping the Next.js v13 product page, utilizing the shadcn/ui and Aceternity UI libraries, in conjunction with leveraging SSR for much more performant page load times and responsiveness
  • Improved the overall application security for our core Live Updates Platform by protecting against CSRF with internally managed secure tokens, leveraging AWS Secrets Manager, and removed PII from all logs across our ECS and Lambda Cloudwatch logs

Anago (Open Source) | Full Stack Software Engineer

Jun 2023 - Mar 2024

San Francisco, CA

  • Configured and deployed cloud-hosted and locally-managed Kubernetes clusters with AWS EKS, ultimately improving our developer velocity while maintaining cost optimization strategies for cross functional teams
  • Architected Node v20 and Express Infrastructure Notification Services with AlertManager to ensure timely, user-controllable alerts, empowering consumers to resolve cluster performance issues and foster long-term operational stability across complex microservices
  • Integrated Prometheus into the K8's Health Observability Platform to ingest real time metrics for CPU, memory, and performance statistics, enabling engineering teams to monitor cluster health and performance
  • Product developed under tech accelerator OSLabs (opensourcelabs.io)

NYC Office of Chief Medical Examiner | Analyst

May 2022 - Jan 2023

New York, NY

  • Collaborated within our departmental team to optimize scheduling and sample batching, enhancing testing efficiency by 20%
  • Implemented and adhered to quality assurance standards while contributing to the development and enhancement of documentation and protocols, resulting in improved operational efficiency and data integrity
