• Released Android 15 globally to all customers on VDC
• Debugging Android Emulated Graphics for some of our most important customers
• Collaborating to create a roadmap for Android Emulators as a Service

Made 1K open-source JavaScript repositories available for Fine-Tuning via a gRPC API using Go, AWS & Docker Distribution on Kubernetes.

• On-call for the platform that rolls out new versions, progressively, to 100,000+ Grafana instances across ~12 regions.
• Reduced the time to readiness of new Grafana Cloud instances from minutes to seconds by optimizing the request path across multiple services receiving ~100 reqs/day using Go, Kafka & MySQL.
• Migrated creation of Grafana Cloud instances from a synchronous legacy Node.js codebase to an asynchronous, fault-tolerant service in Go, iteratively & without disruption.
• Researched, designed & POC-ed an approach to reduce the “Lead Time“ of new Grafana Cloud plugins from ~2 weeks to ~2 days.
• Deployed the progressive rollouts service to new regions in AWS, Azure & GCP.

• On-call for 150+ Kubernetes clusters in 3 availability zones with automated upgrades.
• To keep up critical social momentum for Zalando's migration to Kubernetes, built "kube-reporter", an email-based, reporting tool in Go & Google Apps Script to track the internal migration of 5000+ applications to Kubernetes.
• To continuously validate HTTP config for 100s of applications, implemented a Validating Admission Webhook for RouteGroups, Zalando's alternative custom resource to Ingress for advanced HTTP routing. [Blog Posts]
• To track cluster SLOs of 150+ clusters as Prometheus metrics, implemented "Kube-lifecycle-metrics", a client-go based application.
• To secure Zalando against malicious DNS takeovers, built a tool to monitor AWS, Route53 Hosted Zone delegations in 300+ AWS accounts.

• Showed the significant presence of Python at Zalando by deploying a proof of concept, data pipeline on Kubernetes.

  • Built using open-source components to visualize internal "Programming Language Traffic" based on GitHub API.

• On-call for Google Cloud Infrastructure, spanning 4k+ instances.
• Increased build health transparency by visualization releases using the ELK stack.
