Hi, I'm
Buddhisha.
Results-driven infrastructure specialist bridging traditional networking and automated DevNetOps workflows. Building secure, scalable environments with Python, Ansible, and multi-vendor toolchains across Cisco, HPE, SonicWall, Fortinet, and Aruba platforms.
/usr/bin/whoami
B.Tech Undergraduate in Network Technology at the University of Vocational Technology (Ratmalana), with hands-on enterprise experience at Delko Technologies (Sri Jayawardenepura Kotte). My focus is shifting towards multi-vendor network programmability — transforming manual CLI operations into asynchronous, event-driven automation pipelines.
Previously served as an Internship Trainee at the University of Colombo NOC, resolving fiber optic and Layer 2/3 issues in a live campus environment. Certified across Cisco (CCNA), Microsoft Azure, and ISC2 Cybersecurity domains. Based in Kandy, Sri Lanka — originally from Halloluwa, Kandy.

project_01
PCIRS_Engine
Predictive Change Impact & Risk Simulation Engine
A multi-vendor DevNetOps dashboard built with Python, Netmiko, and Paramiko that centralizes network management, backups, and deployments into a single pane of glass. The core engine features a locally hosted LLM pipeline that preemptively validates configuration candidates for syntax accuracy, routing logic, and security vulnerabilities prior to execution. Couples AI-driven risk assessment with high-concurrency SSH interactions, proactive alerting, and automated rollbacks.
project_02
AegisOps-NMS
Distributed Event-Driven Network Management System
A distributed NMS built with React, Go, and Python. Leverages RabbitMQ to decouple the API gateway from execution nodes, enabling concurrent zero-downtime bulk operations across multi-vendor infrastructure. The backend features an async Python worker pool using Netmiko + PySNMP for non-blocking CLI parsing and SNMP polling. Secured by an AES-encrypted PostgreSQL credential vault with strict RBAC, streaming live telemetry via WebSockets.
project_03
Network Automation — Bulk Config
Python scripts using Netmiko and Ansible to automate bulk configuration changes on multi-vendor switches (HPE, Cisco, Aruba, BDCom), reducing manual task time by 60%.
project_04
Centralized Auth (RADIUS/NPS)
Configured Windows NPS (RADIUS) for secure SSH access control across legacy HPE Comware and modern Aruba OS environments, enforcing AAA policy across campus-grade infrastructure.
project_05
Log Management — Graylog SIEM
Implemented a centralized Syslog server using Graylog on Ubuntu for real-time security incident detection and network performance analysis across enterprise client sites.
project_06
VMware ESXi / TrueNAS Infra
Built VMware ESXi server infrastructure with TrueNAS Scale providing reliable iSCSI and NFS shared storage for virtualization workloads in a homelab/enterprise environment.
