## Work Experience
### Software Engineer @ Wellth

### Software Engineer @ Salesforce
Jan 2022 – Jan 2023
· Used Spring Boot for developing Salesforce Database Connectors to enable real-time access to external data without importing or copying it into Salesforce, achieved a 40% reduction in storage costs and a 30% in data retrieval speed.
· Used OData (Open Data Protocol) and REST APIs to fetch metadata and create external objects that mirror external data. Simplified data sharing and querying. Improved data synchronization by 50% with CDC (Change Data Capture), webhooks, and scheduled polling, ensuring real-time updates.
· Developed a custom Apex connector to integrate Salesforce with an RDS database, using AppSync for GraphQL resolvers, reducing round trips by 35% by using GraphQL to fetch all required data in a single request.
· Transformed SQL DDL to GraphQL schema, enabling AWS Lambda to dynamically build SQL queries and support complex data retrieval without backend changes. Reduced query response time by 45% by aggregating data from multiple RDS sources in a single GraphQL query.
· Managed Kafka-based data pipelines to handle data flows between Salesforce and external systems, performing operations such as format conversion, field mapping, and data enrichment to ensure high-quality data.
· Used Docker to package applications into containers, making it easier to deploy and manage them consistently across different environments. Used Kubernetes to manage these containers, automatically handling tasks like scaling up or down, finding services, and balancing the load to improve communication and reliability of microservices.
