Experience
From full-stack development to enterprise platform engineering, building cloud-native infrastructure and delivering reliable systems at scale.
- Core contributor to an internal Crossplane-based Kubernetes platform product. Authored 60+ Crossplane compositions in KCL for declaratively provisioning infrastructure across AWS, Azure, Vault, Keycloak, and Grafana Cloud.
- Maintained a platform addon catalog of 200+ Helm charts — operators, instances, and configurations deployed via ArgoCD across multi-tenant OpenShift clusters.
- Delivered customer SRE engagements including Jazz (Telecom) VMware-to-OpenShift migration using KubeVirt, incident response, cluster health monitoring, and operational runbooks.
Crossplane Compositions (KCL)
Built 60+ compositions in KCL with reusable framework libraries — AWS S3/IAM/Route53, AzureAD PIM, Vault, Keycloak, HyperShift hosted clusters, and Grafana OnCall.
Platform Orchestration Layer
Designed compositions that wire together all managed addons based on deployment variant and target platform, enabling repeatable multi-environment provisioning.
Identity & Access (Keycloak/Vault)
Authored Crossplane compositions for Keycloak realms, AzureAD IDP integration, Vault OIDC/JWT auth, and cert-manager TLS automation with Let's Encrypt.
Helm Charts & Grafana Dashboards
Maintained open-source Helm charts — ArgoCD, etcd, cert-manager, SLO, and tenant Grafana dashboards. Built OADP/Velero backup configurations with Kopia.
Platform CLI (Go)
Developed a Go-based CLI for the platform — preflight validation, status commands, Crossplane package building and testing workflows.
GitOps & Multi-Cluster Delivery
Managed ArgoCD-based GitOps across prod, nonprod, and sandbox environments. Resolved StatefulSet SSA conflicts and operator lifecycle at scale.
- Designed and developed custom CRM modules, fields, and workflows in SuiteCRM to streamline business processes.
- Automated repetitive workflows and reporting pipelines, reducing manual effort and improving team productivity.
- Ensured seamless integration of SuiteCRM plugins by leveraging deep understanding of application architecture.
- Diagnosed and resolved WordPress issues through effective debugging, ensuring high availability and smooth operations.
- Integrated third-party APIs into WordPress to extend functionality and enhance external service connectivity.
