Work Experience
Amdocs Philippines
Software Developer - Network Automation Engineer
May 2025 — Present- Designed and developed Python-based operational tooling and backend services within the network team for configuration backups, health checks, API integrations, and operational analysis, improving workflow efficiency and reducing repetitive manual tasks.
- Developed firewall policy extraction and validation workflows across hundreds of rules and multiple firewall platforms within network operations, reducing policy analysis turnaround from weeks to seconds through reusable automation pipelines.
- Implemented a cache-based firewall auditing and filtering service for network operations that enabled near real-time rule lookups, minimizing redundant API requests and eliminating repetitive manual extraction workflows.
- Built an end-to-end observability pipeline for network monitoring that automated iPerf and MTR data ingestion, aggregation, and analysis into a time-series database and dashboards, enabling centralized monitoring and alerting while replacing manual connectivity diagnostics.
- Contributed to an AI initiative within the network team by implementing backend integrations for AI-assisted operational workflows via a centralized orchestration API, enabling a team-specific web interface with a fallback local UI for operational resilience. The system supported agent execution, tool routing, and API-driven automation for health checks, log analysis, and network operations.
- Deployed and maintained containerized automation services using Docker, Semaphore, Ansible, and Git-based workflows within network operations, reducing repetitive operational tasks from over 30 minutes to seconds through centralized automation pipelines.
Bridge360 IT Solutions
Product Development Intern
Jun 2024 — Aug 2024- Collaborated with fellow interns to design, develop, and document a responsive web application using the MERN stack, with mobile access via Progressive Web App (PWA) support.
- Redesigned and optimized the database schema to improve query efficiency, enforce data integrity, and support scalable file and image handling for faster resource access and storage.
- Implemented RESTful API endpoints and backend services to enable reliable system functionality and smooth integration between components.

Architectural Samples
I'm currently working on compiling a collection of architectural samples and design patterns that showcase system design, infrastructure solutions, and automation frameworks.
Check back soon for comprehensive case studies, diagrams, and deep-dives into real-world architectural decisions and implementations.
About Me
Hi, I'm Patrick Dionisio, a Software Developer working within a network operations environment, focused on turning manual operational processes into scalable software systems. I started in a role where network operations involved a significant amount of manual and repetitive workflows. With support from my manager and team, I was able to explore and take ownership of automation initiatives, building tooling, backend services, and observability systems to improve operational efficiency and reliability. Over time, this evolved into designing internal systems for workflow automation, data collection, and integrations across operational tools, helping reduce manual effort and shift processes toward more system-driven execution. My experience sits at the intersection of software engineering and infrastructure operations, where I focus on building practical, maintainable systems that improve how operational work is done. I'm currently interested in backend engineering, infrastructure automation, and AI-assisted systems that transform operational data into actionable workflows and insights.
