Scalability and Performance

• Architected for Scale: Led key initiatives that enabled the platform to support a 2500% increase in object handling, from 1,000 to 25,000 objects.
• Optimized Data Ingestion: Achieved a 5x increase in data ingestion speed within the MySQL connector, significantly boosting system efficiency and throughput.
• Database Interaction at Scale: Engineered a metadata system that scaled the ETL platform by 15x, allowing for massive improvements in core database interactions.
• Source Object Generation: Optimized the source object generation flow, resulting in a 10x improvement in pipeline performance and enabling support for larger datasets.
• Reduced Catalog Document Size: Drove efforts to reduce the catalog document size, leading to improved performance and scalability across the platform.

CDC Framework Project

• Ownership and Execution: Led the complete implementation of real-time CDC framework using Debezium Engine (open source) which significantly enhanced data synchronization and ensured seamless real-time updates.
• Schema Catalog Service:
  • Designed and built a generic schema service from scratch to manage and validate data schemas in ETL pipelines, with seamless integration and testing using Debezium connectors.
  • Supported source-specific features, including handling unchanged toast datum from PostgreSQL and diverse data types from various data sources, ensuring flexibility across different ETL environments.
  • Implemented schema versioning, metadata management, and compatibility checks to maintain data quality, streamline data processing, and accommodate schema evolution.

System Optimization and Security Enhancements

• Standardized Error Handling: Spearheaded the initiative to create a unified standard for HTTP and gRPC request failures across the control plane, which improved user experience and reduced support overhead.
• Enhanced Security and Governance: Implemented source/destination whitelisting and played a key role in the Connectors Flag GA for Hevo 1.0.
• REST API Security Enhancements: Enhanced the REST API connector by implementing OAuth 2.0 authorization, improving security and user management.

Feature Development and Integrations

• Led the implementation of several new features including Session Logs, YML template support, advanced scheduler with Cron support, and Terraform integration.
• Spearheaded the development and launch of the SurveyMonkey connector, contributing to the expansion of Hevo's connector ecosystem.

Critical Customer Issue Resolution

• Managed and resolved several complex customer issues for key clients, significantly improving customer satisfaction.

Innovative System Enhancements

• Real-time Logs Implementation: Implemented data governance tool to handle PII redaction in near real-time using AWS S3 and AWS Comprehend, ensuring data privacy and enhancing user experience.
• Microservices and Task Execution: Worked on integrating a microservices architecture on AWS Fargate and implemented a Temporal-based task execution system, improving reliability and streamlining hierarchical DAG processes.

Team Contribution and Documentation

• Regularly contributed to improving documentation quality and conducted knowledge transfer sessions, fostering team collaboration.

Dgraph Labs hosted the 'Hack and Slash GraphQL' hackathon to showcase the power of Slash GraphQL.

• Developed a web scraper using GraphQL to leverage the nesting power of it.
• You have a single query resolver called scrape that takes in a URL as a parameter and returns a generic defined entity such as an HtmlNode
