Cloud Native Rockstars 2026 Company Award finalist, 3rd place, while building conference-grade systems around AI-native operations. ## Architecture Case Studies ### Automatic SaaS Restore System - Problem: Restores are high-pressure, manual, and easy to execute inconsistently. - Constraints: Cloud state, safety gates, auditability, and rollback clarity matter. - Architecture: Repeatable restore workflow with dry-run visibility, status checks, and operational handoff. - Result: Recovery becomes a platform capability instead of an emergency script. ### Cloud-Native AI Gateway - Problem: AI usage needs routing, policy, budget awareness, and provider resilience. - Constraints: Latency, observability, prompt safety, rate limits, and failover behavior. - Architecture: Gateway layer for model selection, request shaping, telemetry, and controlled fallback paths. - Result: AI becomes operable infrastructure, not an opaque API call. ### Kanister Backup Restore - Problem: Application-aware Kubernetes restores need more than volume snapshots and manual runbooks. - Constraints: Stateful services, namespace boundaries, object storage retention, test restores, and auditable recovery steps. - Architecture: Kanister blueprints coordinate backup actions, restore actions, validation hooks, and operator handoff around Kubernetes workloads. - Result: Restore behavior becomes repeatable, reviewable, and easier to exercise before an incident. ### GitOps ArgoCD Flux - Problem: Teams need a clear delivery model before GitOps becomes another layer of operational confusion. - Constraints: Multi-environment promotion, drift detection, rollback safety, secret handling, and developer feedback loops. - Architecture: Comparison of Argo CD and Flux reconciliation patterns, sync ownership, policy boundaries, and platform team responsibilities. - Result: GitOps decisions become explicit platform contracts instead of tool preference debates. ### SBOM Integration - Problem: Software supply-chain data is often generated late, stored separately, and disconnected from deployment decisions. - Constraints: CI/CD speed, artifact provenance, vulnerability context, policy gates, and developer-readable remediation feedback. - Architecture: SBOM generation in the pipeline, artifact attachment, vulnerability enrichment, policy evaluation, and release evidence storage. - Result: Supply-chain visibility becomes part of the delivery system, not a quarterly compliance export. ### LLM Infrastructure Runtime - Problem: LLM workloads move faster than traditional platform controls and can quickly become expensive, opaque, and hard to operate. - Constraints: GPU/CPU placement, model latency, token cost, prompt boundaries, provider limits, data privacy, and fallback behavior. - Architecture: Runtime layer with model routing, request budgets, telemetry, policy checks, provider abstraction, and operational dashboards around inference flows. - Result: LLM usage becomes a controlled platform capability with observability and operating contracts instead of isolated API calls. ### RAG Knowledge Platform - Problem: Engineering knowledge is spread across repositories, runbooks, tickets, architecture notes, and project history. - Constraints: Source freshness, citation quality, chunking, access boundaries, hallucination control, and explainable answers. - Architecture: Curated ingestion pipeline with markdown exports, project metadata, embedding-ready documents, source references, and fallback local answers. - Result: The AI assistant can answer infrastructure questions with project context, sources, and a safer boundary around what it knows. ### EKS Platform Foundation - Problem: Kubernetes clusters become inconsistent when networking, identity, ingress, storage, and observability are assembled per project. - Constraints: AWS account boundaries, workload identity, node lifecycle, ingress policy, autoscaling, logging, and upgrade safety. - Architecture: EKS foundation with Terraform modules, baseline add-ons, workload identity, GitOps bootstrap, default observability, and controlled environment overlays. - Result: Clusters become a repeatable platform product rather than a one-off infrastructure build. ### OpenTelemetry Observability Mesh - Problem: Metrics, logs, and traces often exist separately, making incidents slower and ownership unclear. - Constraints: Cardinality, sampling, cost, multi-service correlation, dashboard sprawl, and alert fatigue. - Architecture: OpenTelemetry collection layer with service conventions, trace context propagation, metric normalization, log correlation, and dashboard/runbook links. - Result: Production behavior becomes easier to understand from request path to workload to infrastructure signal. ### SLO Driven Monitoring - Problem: Dashboards can look healthy while users experience latency, errors, or degraded workflows. - Constraints: Service ownership, error budgets, burn-rate alerts, noisy dependencies, and product-facing reliability language. - Architecture: SLO model with user-centric indicators, burn-rate alerts, Grafana-style views, incident thresholds, and runbook context near alerts. - Result: Monitoring shifts from raw infrastructure charts to reliability decisions teams can act on. ### Multi Region GitOps - Problem: Multi-region systems need repeatable promotion and rollback without turning every deployment into manual coordination. - Constraints: Regional overlays, failover state, secret distribution, traffic switching, drift, and environment-specific policy. - Architecture: GitOps layout with regional overlays, promotion gates, sync waves, health checks, and clear ownership between platform and application teams. - Result: Regional delivery becomes auditable and reversible while keeping infrastructure state understandable. ### Terraform Platform Modules - Problem: Cloud platforms drift when teams copy infrastructure snippets and adjust them under delivery pressure. - Constraints: Module versioning, state boundaries, reviewable plans, environment variance, and provider upgrade safety. - Architecture: Terraform module contracts for networking, EKS, IAM, storage, DNS, and platform defaults with CI-compatible plan workflows. - Result: Infrastructure changes become reviewable product changes instead of undocumented console state. ### ArgoCD App of Apps - Problem: As platforms grow, application onboarding, add-ons, and environment drift become hard to reason about. - Constraints: Bootstrap order, namespace ownership, secrets, cluster add-ons, team autonomy, and rollback visibility. - Architecture: Argo CD app-of-apps pattern with platform add-ons, application sets, sync waves, health checks, and environment-level ownership. - Result: Platform state becomes visible in Git and easier to bootstrap, audit, and recover. ### Policy as Code Guardrails - Problem: Security and platform rules are often discovered only after deployment or during reviews. - Constraints: Developer experience, admission control, exception handling, auditability, and avoiding fragile gatekeeping. - Architecture: Policy-as-code guardrails with OPA/Kyverno-style checks, CI feedback, admission policies, and documented exception paths. - Result: Teams get fast feedback while platform standards are enforced consistently across environments. ### Secrets and Certificate Automation - Problem: Manual secret rotation and certificate handling create outage risk and hidden operational debt. - Constraints: Rotation cadence, Kubernetes consumption, identity boundaries, audit trail, renewals, and emergency revocation. - Architecture: Secret delivery model with external secret sources, workload identity, certificate automation, renewal monitoring, and rotation runbooks. - Result: Sensitive material becomes lifecycle-managed infrastructure instead of scattered manual state. ### Incident Runbook Automation - Problem: Incidents are slower when context, dashboards, logs, and recovery steps live in different places. - Constraints: On-call pressure, incomplete symptoms, permissions, dry-run safety, and post-incident learning. - Architecture: Runbook-linked alerts with diagnostic commands, status checks, escalation context, safe remediation steps, and follow-up documentation hooks. - Result: Incident response becomes calmer, more repeatable, and easier to improve after the event. ### Self Healing Infrastructure - Problem: Transient infrastructure failures can become user-facing incidents when recovery depends on manual detection. - Constraints: False positives, blast radius, rollback safety, observability confirmation, and human override. - Architecture: Failure detection with health signals, bounded remediation actions, chaos validation, alert correlation, and operator approval for risky paths. - Result: Common failure modes can recover faster while preserving control over high-risk actions. ### AI Runtime Execution Plane - Problem: AI workloads often start as API calls but become production systems that need identity, policy, scaling, telemetry, and clear ownership. - Constraints: OpenAI-compatible interfaces, MCP tool boundaries, model-serving latency, Kubernetes autoscaling, OIDC, audit trails, and cost visibility. - Architecture: Execution plane with AI gateway routing, MCP governance, intent proxy, KServe/vLLM serving paths, KEDA scaling, Redis state, OIDC identity, and OpenTelemetry traces. - Result: AI execution becomes a governed platform surface instead of scattered application code and unmanaged provider calls. ### Developer Platform Interface - Problem: Developers lose time when every deployment, environment, and infrastructure request requires platform team translation. - Constraints: Self-service boundaries, golden paths, ownership, auditability, and avoiding an unmaintainable portal. - Architecture: Platform interface with paved workflows, templates, environment contracts, GitOps-backed changes, and visible operational status. - Result: Teams can ship through clear platform paths while platform engineers keep control of the underlying system. ### Cost and Token Observability - Problem: AI and cloud costs can grow quietly when usage is disconnected from teams, services, and deployment changes. - Constraints: Token attribution, cloud tags, model pricing, request volume, budget alerts, and developer-readable reports. - Architecture: Cost telemetry tied to services, AI gateway requests, deployment events, dashboards, and threshold-based feedback loops. - Result: Cost becomes an operational signal teams can understand before it becomes a finance surprise. ### FleetDM Endpoint Visibility - Problem: Endpoint visibility is often separate from cloud and Kubernetes operations, leaving security context incomplete. - Constraints: Device inventory, query safety, rollout control, privacy, vulnerability context, and integration with existing operations. - Architecture: FleetDM-style visibility layer connected to inventory, policy queries, vulnerability signals, and operational reporting. - Result: Endpoint state becomes part of the broader infrastructure picture instead of a separate security island. ### Zero Trust Service Mesh - Problem: Internal traffic is often trusted by default, making lateral movement and policy gaps hard to see. - Constraints: Service identity, mTLS, policy rollout, observability, latency overhead, and developer debugging. - Architecture: Service mesh model with workload identity, mTLS, authorization policy, traffic telemetry, and progressive rollout controls. - Result: East-west traffic becomes governed, observable, and easier to reason about during security reviews and incidents. ## Selected Projects ### ai-runtime-platform - URL: https://github.com/justrunme/ai-runtime-platform -
