Expert guide for designing robust, scalable, and resilient backend systems. Covers modern patterns including Microservices, Event Sourcing, CQRS, and advanced API contracts (REST, GraphQL, gRPC). Specializes in defining service boundaries, implementing distributed transactions (Saga), and integrating comprehensive security measures like OAuth 2.0 and mTLS.

Generates production-ready Kubernetes deployment, service, ingress, and autoscaler manifests using best practices such as health checks, TLS, and resource limits. Use this when creating or updating deployments, services, ConfigMaps, Secrets, or other Kubernetes resource manifests for any application.

This guide provides advanced strategies for optimizing API usage with Linear, helping users stay within strict rate limits and minimize operational costs. It covers best practices like replacing polling with webhooks, implementing request coalescing, minimizing query complexity, and utilizing smart caching with tailored TTLs, ensuring maximum throughput efficiency.

A comprehensive guide to production-grade patterns for Linkerd, a lightweight, security-first service mesh for Kubernetes. This resource covers essential concepts like automatic mTLS, advanced traffic routing (e.g., canary deployments, A/B testing), service resilience using retries/timeouts, and robust access control policies, enabling reliable microservices architecture deployment.

Manages SSL/TLS certificates via the ssl-certificate-manager plugin by checking expiry dates, renewing certificates, listing installations, and reporting results to keep connections secure and troubleshooting informed.

A comprehensive guide to implementing Mutual TLS (mTLS) for achieving zero-trust, secure service-to-service communication within a service mesh. This skill provides templates and concepts for configuring mTLS using industry standards like Istio, Cert-Manager, and SPIFFE/SPIRE, ensuring robust certificate management and encrypted internal communication.

Helps analyze and enhance application caching strategies by reviewing TTLs, key structures, hit rates, and invalidation policies to boost Redis or Memcached performance.

This skill provides comprehensive, multi-layered diagnostic scripts for resolving complex and intermittent issues with the Perplexity Sonar API. It allows users to test connectivity (DNS, TLS, TCP), profile API latency, validate citation stability, and verify search recency filters. It is crucial when standard troubleshooting methods prove insufficient for diagnosing hard-to-replicate API bugs or performance regressions.

A comprehensive guide to implementing secure secrets management practices for Continuous Integration/Continuous Deployment (CI/CD) pipelines. It covers using industry-leading tools like HashiCorp Vault, AWS Secrets Manager, Azure Key Vault, and GCP Secret Manager to securely store, retrieve, and automatically rotate credentials (API keys, database passwords, TLS certificates) without hardcoding them into source code. Includes best practices for least-privilege access and audit logging.

An expert architect specializing in designing and optimizing service mesh using industry leaders like Istio and Linkerd. This skill provides deep knowledge of cloud-native networking patterns, enabling secure, reliable microservices communication. It covers advanced topics including zero-trust networking, mTLS configuration, sophisticated traffic management (e.g., canary and blue-green deployments), observability integration, and multi-cluster federation.

A comprehensive guide for designing and implementing production-grade microservices using gRPC in Go. Covers best practices for API contract standardization with Protobuf and Buf, securing service-to-service communication via mTLS, and integrating deep observability using OpenTelemetry interceptors. Ideal for building high-performance, reliable internal APIs.

Expert guide for building durable distributed systems with the Temporal Go SDK, covering deterministic workflow rules, mTLS worker configuration, advanced patterns, and testing/observability strategies for production workloads.
