Operational IT experience,
not just classroom theory.
ISP Operations
Applied ISP operations knowledge gained through hands-on project work and technical training — covering connectivity diagnostics, fiber installation, and supporting live infrastructure environments.
Networking & Connectivity
Hands-on router configuration and deployment, fiber optic splicing, SC connector termination, and end-to-end connectivity troubleshooting using TCP/IP and diagnostic tooling.
Virtual Machine Hosting
Set up and maintained VM-hosted environments to support operational workloads — managing resources, uptime, and system reliability for internal ISP tooling.
Self-Hosted System Dev
Designed and built an internal ISP management system from the ground up — React front-end, MySQL backend, deployed entirely on self-managed virtual machine infrastructure.

ISP Field Operations & Technical Support
Independent / Informal ISP Setup
Managed end-to-end ISP operations including client onboarding, installation, and ongoing technical support.
Performed field installations including router setup, connectivity configuration, and fiber-related work.
Handled technical support and troubleshooting for connectivity and network issues across active client sites.
Managed customer accounts including billing follow-ups and service disconnection procedures for non-payment.
Ensured service stability through periodic client checks and proactive maintenance support.
Data Entry Operator
RT Lawrence Corporation — Philippine Branch
Performed accurate system data entry and validation for operational and financial records, maintaining data integrity across internal platforms.
Conducted data quality checks to ensure system reliability and accuracy — applying the same methodical verification mindset used in network fault diagnosis.
Processed financial transactions and coordinated data submissions to banking systems, requiring strict attention to format and procedural compliance.
Assisted in resolving system and workflow issues during daily operations, troubleshooting internal software irregularities and escalating when needed.
Trained new staff on internal systems, procedures, and accuracy standards — demonstrating the ability to communicate technical processes clearly.
Bachelor of Science in Information Technology
Dr. Yanga's College · Bocaue, Bulacan
Completed a BS in Information Technology with coursework covering networking fundamentals, systems administration, database management, and software development — applied directly in self-hosted project work and operational ISP environments.
Built for real operations,
not just portfolios.
Self-Hosted ISP Management System
Designed, built, and maintained an internal management system for an ISP operational environment. The system streamlined customer record management, billing workflows, and ticket tracking — reducing manual overhead and improving team coordination.
- Deployed and hosted the system on a virtual machine environment — full self-managed infra
- Configured server networking and external access for remote connectivity
- Applied firewall and networking concepts to maintain system stability and secure access
- Diagnosed and resolved connectivity and hosting-related issues during deployment
- Developed frontend components using React; integrated MySQL database storage
- Maintained system reliability and performed troubleshooting during active use
SYSTEM ARCHITECTURE
How I work through
real technical problems.
Step-by-step workflows applied across networking, fiber installation, router deployment, and VM infrastructure — drawn from hands-on experience.
Network Troubleshooting
Receive Issue Report
No internet / slow connection / intermittent signal
Identify Issue Type
No connectivity · Weak or unstable signal · Authentication / access issue
Basic Checks
Physical cable inspection (LAN/fiber drop), router/modem status lights, customer-side setup validation
Network Diagnostics
Ping test (gateway / external IP), check IP assignment (DHCP issues), verify connectivity stability
Isolation
Determine if issue is customer-side or ISP-side
Action
Router reconfiguration (reset / re-auth / re-provision), replace or re-terminate fiber connection if needed
Resolution Verification
Test browsing / speed stability, confirm uptime restoration with user
Fiber Optic Installation & Maintenance
Site Preparation
Identify installation point, ensure proper routing path for fiber cable
Fiber Preparation
Strip fiber cable safely, clean and prepare fiber core
Splicing / Termination
Perform fusion splicing OR SC connector termination
Signal Verification
Test optical signal strength using basic continuity or testing tool if available
Physical Securing
Protect splice points, organize cable routing for durability
Final Testing
Confirm stable connection at endpoint, validate internet connectivity after activation
Router Configuration & Deployment
Device Intake
Receive router/device for deployment or reset
Access Config Panel
Log into device configuration interface
Configure Settings
WAN settings · LAN IP structure · WiFi SSID & security settings · ISP-specific configuration
Test Connectivity
Internet access validation, local network stability check
Deploy
Hand off to user or install at site
Post-Check
Monitor connection stability, re-adjust settings if needed
Virtual Machine Hosting / System Setup
Host Preparation
Prepare host machine or server environment
VM Platform Setup
Install virtualization platform, create and configure virtual machine (CPU / RAM / storage / OS)
Network Configuration
Bridge or NAT setup, ensure VM is reachable for remote access if needed
Deploy Services
Run ISP management system — React frontend + MySQL backend setup
Monitoring
Check uptime and resource usage, restart or optimize when needed
Maintenance
Updates, backup handling, system stability checks
