Work Experience
Amdocs Philippines
Software Developer - Network Engineer
May 2025 — Present- Supported daily Network Operations activities, including ticket handling, network monitoring, incident analysis, and troubleshooting while collaborating with network engineers to investigate issues, validate findings, and maintain network reliability and service availability.
- Developed backend services and an internal web application supporting AI-assisted operational workflows for the network team, exposing well-defined APIs that enabled integration with internal AI initiatives while maintaining independent operation.
- Designed and implemented a centralized Firewall Service that integrated with multiple firewall platforms, providing policy extraction, rule filtering, request validation, expiry monitoring, and auditing to reduce repetitive manual analysis and operational effort.
- Developed a custom OIDC identity bridge for the network team's internal operational applications using Spring Boot and Python, exposing existing RADIUS authentication through standardized OIDC interfaces while decoupling applications from the underlying authentication provider and enabling future federated identity integration.
- Developed additional monitoring capabilities using iPerf3, InfluxDB, Telegraf, Grafana, and Loki to enhance network troubleshooting workflows, enabling performance analysis through controlled traffic testing and packet loss measurement while centralizing critical network device and server logs from existing syslog sources.
- Developed Python automation tools for configuration backups, health checks, operational analysis, and system integrations, reducing repetitive manual effort and improving workflow efficiency within the network team

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.
