• Built APIs for insights data supporting a dynamic observability frontend platform and metrics report generation.

• Implemented rate limiting for ingestion cardinality reducing pipeline lag, improving SLA success rate and latency.

• Developed scalable datasources for storing and querying insights data at scale using Kafka, Druid and Bigtable.

• Migrated synchronous APIs to asynchronous workflows, increasing throughput and improving reliability for web and CLI clients.

• Implemented operation checks using insights metrics to ensure safe rollouts of federated GraphQL schemas.

• Developed Kafka connect transforms for manipulating change data capture (CDC). This replaced a custom legacy system with a modern Debezium Kafka Connector with faster streaming capabilities making user events available to consumers within seconds of the change taking place in the database.

• Deployed Kafka Connectors using Kubernetes for controlled blue-green rollouts. Created dashboards using Prometheus for enhanced observability into deployed Connectors and their streaming uptime.

• Led the development efforts of a metadata store for storing the topology of Kafka Connect clusters. Enabled SREs to quickly debug Connect clusters and attribute instances to teams and domains.

• Developed .NET core messaging libraries to stream records through Kafka. Libraries consisted of encryption/decryption, compression/decompression, schema validation using Kafka schema registry, and message serialization/deserialization through Java class-based annotations. Sped up internal developer workflows by standardizing consumption of events from the message store with versioned payloads.

• Developed cloud governance tools to manage AWS resources with non-compliant configurations. Protected against over spending of resources and enforced automatic shutdown using a quota system.

• Developed user-facing access methods to instances over SSH and RDP. Enabled private connections to resources such as EC2, SQL & Redshift without publicly exposing the instance or resource to an outside IP
