Enterprise Elasticsearch Consolidation at Adobe
Architect & Technical LeaderAdobe’s search infrastructure was fragmented across 18+ managed clusters with varying versions, driving high licensing costs and operational complexity.
Managed service lock-in and version fragmentation were creating a multi-million dollar licensing burden without the necessary operational control.
Constraints: 10B+ documents, 6K/sec ingestion, zero-downtime migration requirement.
- Migrated 18 managed AWS Elasticsearch clusters to a standardized, self-managed hybrid architecture.
- Transitioned the entire stack from proprietary managed versions to a unified Open Source version.
- Engineered automated data lifecycle and tiering policies for 10B+ documents.
- Millions in annual savings, 30% cost reduction
- Reduced annual Elasticsearch licensing costs by millions of dollars (30% net savings).
- Achieved full operational control over search performance and security posture.
- Maintained sub-5ms P95 search latency while sustaining 6K/sec ingestion throughput.
- Standardization is the prerequisite for cost optimization at scale.
- Moving to Open Source provides financial leverage and eliminates vendor lock-in.
Global SRE Operating Model at F5
Sr. Director of Product Engineering & Head of SREF5’s Distributed Cloud platform powers global multi‑cloud networking and security for enterprise customers.
Silos, inconsistent incident response, and burnout were slowing down a platform facing explosive traffic growth.
Constraints: 24/7 global operations, strict compliance (FedRAMP, PCI‑DSS), and security‑critical workloads.
- Rebuilt SRE into a follow‑the‑sun model with clear ownership and escalation paths.
- Implemented policy‑as‑code and zero‑trust architecture across the platform.
- Modernized observability with ML‑driven anomaly detection and unified tracing.
- 55+ engineers, MTTR −73%
- Reduced MTTR by 73% and improved incident consistency.
- Lowered attrition by 10% by eliminating hero culture.
- Absorbed 400% growth in attack traffic without degradation.
- Culture eats tools for breakfast, fix trust and clarity first.
- Compliance-as-code is the only sustainable path at enterprise velocity.
FedRAMP High & Zero-Trust Architecture at F5
Sr. Director of Product Engineering & Head of SREF5's Distributed Cloud platform required the highest levels of security to serve federal and highly regulated enterprise customers.
Achieving and sustaining high-bar compliance (FedRAMP High) while maintaining rapid feature velocity in a multi-cloud environment.
Constraints: Global footprint (25+ PoPs), complex multi-tenant networking, and zero-trust requirements.
- Architected a zero-trust platform using mutual TLS (mTLS), identity-based policy, and runtime eBPF monitoring.
- Implemented 'Compliance-as-Code' to automate security guardrails across the entire CI/CD lifecycle.
- Collaborated with the CISO to deliver FedRAMP High, PCI-DSS, and SOC 2 compliance through automated evidence collection.
- FedRAMP High, PCI-DSS, SOC 2
- Successfully achieved FedRAMP High, PCI-DSS, and SOC 2 certifications.
- Accelerated feature velocity by 40% by shifting security and compliance left.
- Delivered a unified security posture across 25+ global points of presence.
- Security is not a checkbox; it's a foundational architectural property.
- Automated compliance is the only way to scale security in a distributed system.
Platform Modernization & FinOps at Arkose Labs
Director of Engineering & SREArkose Labs fights fraud at internet scale, requiring real‑time decisioning under unpredictable attack traffic.
Cloud spend was rising faster than revenue, and technical debt was slowing delivery.
Constraints: High‑volume DDoS traffic, strict latency SLAs, and rapid enterprise growth.
- Re‑architected the platform into EKS microservices with an eBPF service mesh.
- Established FinOps governance, dashboards, and cost‑aware engineering practices.
- Introduced SLO‑based release gates to balance reliability and velocity.
- 22% cloud spend reduction
- Reduced cloud spend by 22% while supporting 7x transaction growth.
- Maintained 99.9% SLA even during attack spikes.
- Improved release quality and reduced customer‑impacting incidents.
- FinOps only works when engineering owns the cost model.
- eBPF unlocks observability without the tax of sidecars.
Enterprise CI/CD & Platform Modernization at Macys.com
