👨💻 Senior DevOps Engineer & Systems Administrator
I am a Senior DevOps Engineer with 6+ years of professional experience in core infrastructure, low-level networking, and high-performance system architectures, backed by 14+ years of hands-on development (including early personal and freelance projects). My work bridges the gap between complex network routing—specifically IPv6 transition mechanisms—and reliable, automated backend application delivery.
📍 Based in Sri Lanka — open to relocating to Singapore.
- Infrastructure & Automation: Building, maintaining, and automating highly available production environments. I manage complex, multi-platform server infrastructures using Infrastructure-as-Code (IaC) and comprehensive backup architectures for databases and message brokers with strict high-frequency intervals.
- Network Engineering: Championing global IPv6 adoption. I specialize in IPv6-only server configurations, NAT64/DNS64 setups, and optimizing custom router hardware and firmware (OpenWrt) for optimal system load and DHCP management.
- Full-Stack & Performance Optimization: Developing and maintaining high-traffic platforms, optimizing everything from legacy backend refactoring to database query tuning and modernizing frontend UI frameworks.
- DevOps & IaC: Terraform / OpenTofu, Ansible, Kubernetes, Docker, GitHub Actions, GitLab CI
- Cloud Platforms: AWS, GCP, Azure
- Networking: IPv6 Architecture, DNS, OpenWrt, IP Intelligence (MaxMind)
- Languages & Scripting: PHP, Python, JavaScript, Node.js, Bash/Shell
- Data & Infrastructure: PostgreSQL, Kafka, Restic, Rocky Linux, Ubuntu
- IPv6 Infrastructure & Monitoring (v6monitor / IPv6-dns-server): Building custom Node-based DNS proxies that map out CDN behaviors, and tracking global IPv6 adoption.
- 👉 Note: Many of my core IPv6-focused projects are actively maintained on my GitLab due to their native IPv6 support.
- BeeIMG Image Hosting: Primary developer focused on continuous optimization of both the backend database structures and the frontend delivery components to ensure fast, reliable image serving.
- Tonga Government CRVS – OpenCRVS: Delivered and operated OpenCRVS, an open-source civil registration platform, across AWS and on-prem environments, ensuring reliability in low-resource settings.
- Automated Utilities (geolite2legacy & IPv6Data): Developing data-parsing pipelines and conversion tools for IP telemetry and automated infrastructure management.
I actively contribute to the broader ecosystem by helping secure and unblock upstream infrastructure. This includes identifying and flagging missing AAAA records for major package registries (like OpenTofu) and driving improvements in core tools like phpMyAdmin around network binding and CDN fallbacks.
