As a Senior Software Engineer specializing in service modernization, I played a pivotal role in enhancing the functionality, reliability, and performance of key services within our platform. In particular, I led initiatives within the following areas:

• Account Management:

• Spearheaded the modernization efforts for multiple services inherited from another team, ensuring alignment with contemporary industry standards and best practices.

• Implemented advanced instrumentation techniques to enhance service reliability and facilitate comprehensive performance monitoring, contributing to improved user experience and operational efficiency.

• Engineered a seamless migration to an integrated gRPC gateway, significantly reducing latency and optimizing compute resource utilization across the platform.

• Overhauled authorization middleware systems, fortifying security measures and paving the way for seamless integration with future service ecosystems.

• Session Management:

• Designed and implemented robust support for multi-account sessions within the session management system, catering to the diverse needs of our user base and enhancing platform versatility.

• Orchestrated the integration of various company products with the session manager, effectively transitioning them away from legacy platforms and fostering interoperability within our ecosystem.

Through these initiatives, I played a key role in driving the evolution of our platform, ensuring scalability, reliability, and adaptability to meet the ever-changing needs of our users and business objectives.

Collaborated effectively with multiple teams to successfully implement these initiatives, ensuring seamless integration and deployment across the organization:

• Optimized ArgoCD resource hierarchy, resulting in reduced CI/CD pipeline costs and significantly improved build/deploy times;

• Implemented Argo Rollouts within CI/CD processes to enhance deployment reliability and enable rapid rollback capabilities, minimizing user impact from deployment failures;

Led a multi-phased project to migrate from a NoSQL database with highly-connected entities to PostgreSQL, resulting in improved performance and data consistency. Developed a detailed migration plan, collaborated with cross-functional teams, and provided training and support to end-users during the transition. The successful completion of the project resulted in significant improvements in performance, reliability, and data consistency. The system allowed for more efficient querying and analysis of data, which led to improved decision-making processes.

• Reduced the occurrence of bugs and failures in a service that ingested terabytes of data daily by re-designing data ingestion processes around a finite-state machines (FSM) while increasing code readability and maintainability.

• Created an event-based service to extract useful insights from advertiser's videos in order to increase ad delivery using Google's Cloud Functions along with Cloud Storage, Pub/Sub and Video Intelligence API.

• Created tooling that produced code optimized per DSP for faster JSON decoding/encoding during Real-Time Biding (RTB) process.

• Other achievements:

• Added instrumentation to existing codebase.

• Improved existing CI/CD pipeline and made developer's local environment more robust.

• Technologies:

• Golang

• Google Cloud Platform (GCP) products, including: GKE, Pub/Sub, BigQuery, Firestore, Cloud SQL, Cloud Storage, Cloud BigTable, Cloud Monitoring

• Infrastructure and automation: Terraform, Ansible, shell script and Makefile

• PostgreSQL

Architected and implemented a novel technology using TCG's security protocols to enable actual remote attestation of a system by a trusted entity. This novel technology can now be used as a trusted Node Attestor for SPIRE's architecture that allows Kubernetes to only deploy Pods into Nodes that can provide evidence of its integrity.
