Senior Site Reliability Engineer
Peloton Interactive · Remote · Nov 2022 - Present
- Migrated Peloton’s production services off a legacy 250-node Kubernetes monolith onto a fleet of reproducible 100+ node clusters, guiding development teams through load balancer setup and gradual traffic shifts
- Set the technical direction for Peloton’s multi-cluster Istio service mesh spanning hundreds of production services, with independent highly-available control planes, mTLS-secured intra-mesh traffic, and automatic cross-cluster failover enabling zero-downtime cluster rotations (documented in AWS blog)
- Owned capacity planning and pre-scaling for Turkey Burn 2025, sustaining 7.27 billion requests across the multi-cluster Istio mesh at a peak of 452,000 requests/second with zero downtime
- Authored Terraform modules and Helm charts for core cluster components, enabling a new production-grade cluster to be built via ArgoCD and serving live traffic in under 30 minutes
- Built a Kubernetes operator in Rust that automatically scopes Istio proxy configurations based on live traffic patterns, reducing sidecar memory consumption and xDS push latency across the production mesh
- Developed a global rate limiting service in Rust implementing Envoy’s RLS protocol with Redis-backed distributed state, automatically prioritizing traffic to protect critical services during degradation
- Partnered with the social team to feed their moderation signals into mesh-level rate limiting, blocking malicious users at the edge before they reach backend services
- Drove org-wide observability standardization with an end-to-end Istio access log pipeline and embeddable Datadog Powerpacks, adopted across development teams as default instrumentation and reducing support escalations by letting teams self-serve traffic debugging
- Established SLOs for Istio mesh traffic and control plane operations with multi-window burn rate alerting
- Led incident response and root cause analysis for multiple high-severity outages, including DNS resolution failures degrading home screen load times and gateway overload during traffic spikes, implementing fixes that prevented recurrence
Senior Site Reliability Engineer
Tabula Rasa HealthCare (TRHC) · Moorestown, NJ · Mar 2021 - Nov 2022
- Minimized excessive infrastructure alert noise and wrote actionable playbooks for incident mitigation, enabling an on-call rotation
- Transitioned legacy Elasticsearch clusters for app log indexing to AWS OpenSearch
- Developed Terraform modules adding observability and SLA dashboards for products
- Standardized incident response and postmortem practices across the company, improving incident response time by 55%, from 42 to 19 minutes
- Developed Elixir-based chatbot automating paging and other incident practices
- Led observability interest group and presented research on emerging technologies such as OpenTelemetry
Software Engineer
Tabula Rasa HealthCare (TRHC) · Moorestown, NJ · May 2016 - Mar 2021
- Designed and developed cloud infrastructure enabling horizontal scaling and orchestration of regression tests using Ruby and RabbitMQ
- Supported 6 development teams in scaling tests, reducing feedback time on code changes by over 12 business hours and enabling bi-weekly releases to production
- Developed frameworks, design patterns, and production-like data generation libraries for building maintainable regression test code
- Led team responsible for testing, maintaining reliability, and managing releases of the MedWise web-based application suite
- Developed production monitoring tools, automated test suites, and GitLab continuous integration pipelines for MedWise using Ruby and Selenium
- Eliminated nearly all high-impact production regressions within 18 months of test suite development
- Responded to production incidents by analyzing logs and metrics, diagnosing root causes, and communicating workarounds and status to end users
