## Work Experience
### Software Engineer @ Happy Money
Jan 2021 – Present | Orange County, California, United States (Remote)
Tech stack: AWS, Docker, Spring Boot, Microservices, Java, JavaScript/TypeScript, Python, Bash, MongoDB, DynamoDB, Postgres, CodePipeline, CodeBuild, GitHub Actions, Lambda, EventBridge, API Gateway, Dadadog, Gradle, SDKs, CLIs, Nightwatch, Salesforce, Kafka, Swagger, Lombok, JPA/CrudRepository, DevTools
- Build and deploy Lambda services in TypeScript using AWS Event, DynamoDB, CloudFormation, integrated with CodePipeline, GitHub, Jira via SDKs, Datadog, making CRUD into DynamoDB to create DORA metrics from 500 pipelines to measure project targets/performance displaying in graphs for data visualization. Leverage Event triggers to auto-detect/auto-onboard new pipelines and save tremendous efforts (if not possible) to manually change the structure in all the pipelines which can take 1-2 years to complete.
- Build CLI using oclif in JavaScript/NodeJS to generate test templates including TestContainers similarly to cookiecutter in one line of command that save each team's manual efforts from 3-5 days.
- Build local microservices environment using docker, env-vault, moxie services in Java to provide environment on-demand that speeds up development cycle, where the teams can just run one line of command and they'll have the integrated environment brought up for themselves instantly in their local machine.
- Build Pact.io framework in Java REST and Kafka integrated in CI/CD (merge protection in GitHub Actions and deploy protection in the pipeline) for ideal contract testing and as a standard across all teams, where it promotes evolution and freedom in making changes between Providers and Consumers without breaking each other.
- Build parallelization using docker and multi-threading in Java and Python to cut down the execution time to 40-90% for faster deployment flow in the pipeline
- Build REST APIs in Java Spring Boot in the Loan Application microservice transformed from a monolithic Matcha
