Chathura Prabashana

DevOps Engineer & IT Undergraduate

About Me

I am a BSc IT undergraduate specializing in DevOps, system architecture, and backend automation. My focus lies in bridging the gap between development and operations by building resilient architectures, automating workflows, and ensuring system observability. With a strong foundation in low-level systems programming and cybersecurity, I build and maintain infrastructure that scales securely.

Technical Skills

  • Infrastructure & Observability: MongoDB Atlas, UptimeRobot, Firebase Cloud Firestore, Render
  • Automation & Orchestration: Python, Scripting, Local AI Orchestration (Ollama API)
  • Systems & Backend: C, C++, C#, Laravel, MySQL, REST APIs
  • Security: Vulnerability Assessment, Penetration Testing, Threat Analysis

Featured Projects & Infrastructure Experience

  • Cloud Monitoring & Incident Response Managed backend deployment pipelines and observability for web applications hosted on Render. Configured M0 clusters via MongoDB Atlas and implemented UptimeRobot for continuous service monitoring and downtime alerts.

  • Ollama Multi-Agent Orchestration A completely local, air-gapped automation framework utilizing Python. Engineered an autonomous interaction loop between multiple AI agents, demonstrating lightweight orchestration and API integration without relying on external cloud compute.

  • Sine-OS (Systems Architecture) A custom 32-bit x86 operating system built from scratch in C and Assembly. Developing the custom bootloader, Global Descriptor Table (GDT), and VGA terminal driver provided a deep, foundational understanding of kernel-level operations, memory management, and hardware-software interfaces.

  • Automated Data Pipeline Agent A Python-driven automation tool engineered to run daily cron-style jobs, autonomously generating and distributing advanced technical documentation on specialized software and security topics.

  • Multi-Tenant SaaS Architecture Designed the backend schema, relational database architecture (MySQL), and API endpoints for a scalable booking platform using Laravel, ensuring robust data handling for cross-platform clients.

Continuous Learning & Security Operations

Active in continuous security training to better understand infrastructure vulnerabilities, network defense, and secure deployment practices.
