Software engineer focused on DevSecOps, platform engineering, and cloud-native infrastructure.
I am Wilbur, a software engineer with 4+ years of experience across DevSecOps, platform engineering, backend systems, and cloud-native infrastructure. My work is centered on making infrastructure more repeatable, observable, secure, and easier for teams to consume.
Outside of work, I run a homelab and write about the technologies I explore, from Kubernetes distributions and GitOps workflows to the operational lessons that come from keeping systems alive.
Platform Engineering
Building self-service infrastructure platforms with Kubernetes, Crossplane, GitOps, and secure automation patterns.
DevSecOps
Designing CI/CD workflows, infrastructure delivery pipelines, and operational guardrails for cloud-native systems.
AI Infrastructure
Supporting GPU-backed AI/ML workloads with predictable capacity, tenant separation, and production-minded operations.
Kubernetes-native DBaaS
Designed platform abstractions for PostgreSQL provisioning, lifecycle management, backups, and governance.
AWS EKS Delivery Platform
Provisioned secure EKS foundations with hardened nodes, storage drivers, ingress, and load balancing integrations.
Homelab Kubernetes
Exploring production-style operations through Talos Linux, GitOps, observability, and resilient cluster design.
// working principle
Infrastructure should be boring in production.
The best platforms fade into the background: predictable to operate, clear to observe, secure by default, and simple enough for product teams to use without waiting on manual infrastructure work.

DevSecOps & AI Infrastructure Engineer
May 2025 - Present
- •Designed and built a Kubernetes-native Database-as-a-Service platform that automates PostgreSQL cluster provisioning, lifecycle management, backup integration, and operational governance using CloudNativePG, Crossplane, FluxCD, Vault, and S3-compatible storage.
- •Developed Crossplane-based platform abstractions to standardize database provisioning across environments, reducing manual infrastructure work and enabling self-service consumption of PostgreSQL clusters.
- •Built monitoring and observability capabilities with Prometheus and Grafana to track database health, cluster availability, resource usage, and operational signals across the DBaaS platform.
- •Administered NVIDIA H100 Multi-Instance GPU configurations to deliver isolated and predictable GPU capacity for AI/ML workloads, improving tenant separation and hardware utilization.
IBM Singapore
DevSecOps Engineer
Oct 2023 - May 2025
- •Maintained and enhanced DevSecOps pipelines for provisioning AWS infrastructure, supporting microservices, serverless workloads, and monolithic applications across cloud environments.
- •Deployed Amazon EKS clusters using Infrastructure as Code with AWS CloudFormation, leveraging hardened Bottlerocket OS nodes and bootstrapping core cluster add-ons including CSI storage drivers, StorageClasses, persistent volume support, and the AWS Load Balancer Controller for ingress and load balancing.
