James Anthony O. Rosales
I build and deploy reliable web systems on Linux, Nginx, Laravel, AWS S3, and DigitalOcean.
Recent BSIT graduate candidate with production experience at CHED RO V, where I helped ship CAFÉ, integrate SSO/API access, migrate file storage to AWS S3, and support regional education data workflows.

What I Bring
I started in web development, then moved deeper into the delivery layer.
My expertise spans Linux servers, Nginx, DNS, storage, APIs, and the network paths that keep applications usable and resilient in production.
My strongest portfolio signal is practical ownership. I have built Laravel systems, configured production hosting, handled cloud file storage, supported SSO/API integrations, and worked directly with networking and field support tasks.
Network-Aware Delivery
I understand the path from browser to server: DNS, routing, reverse proxies, certificates, firewalls, and database access.
Reliable Operations
I focus on deployability, backups, storage limits, access control, and clear recovery paths before a system becomes fragile.
Practical Automation
I use scripts, GitHub Actions, and repeatable setup steps to reduce manual deployment work and prevent avoidable mistakes.

Proof of Work
The Challenge
A live regional platform for CHED RO V and 200+ HEIs to collect institutional forms, gate file uploads, and generate digital certificates.
My Contribution
Supported the production Laravel environment, moved file assets to AWS S3, secured API access with Sanctum, integrated OneTouch SSO, and prepared multi-year enrollment data with Python scripts.
Implementation Details
- Moved uploaded files away from local disk to prevent server storage pressure.
- Connected OneTouch SSO so institutional users could avoid separate login flows.
- Protected reporting endpoints with token-based Laravel Sanctum access.
- Integrated the system with the CHED Central Office MCP server API to retrieve and search institutional data in real time.
Application Tracking System (PCA)
The Challenge
The Philippine Coconut Authority (PCA) Regional Office V needed a centralized system to track applicant projects, proponent details, and internal approvals, moving away from legacy file-based tracking.
My Contribution
Provisioned a DigitalOcean Linux droplet, configured a LEMP stack, managed DNS and SSL, implemented real-time SMS notifications, and added geospatial application mapping using Leaflet.
Implementation Details
- Limited server access with SSH keys, UFW rules, and disabled root login.
- Configured Nginx server blocks, HTTPS redirects, and Let's Encrypt certificates.
- Scripted daily MySQL backups with rotation for applicant records.
- Implemented real-time SMS notifications for applicant and approval status updates.
- Integrated Leaflet-based geospatial mapping to visualize and track application locations.
