I am currently moving away from GitHub and migrating my active projects to my self-hosted Git server. You can find all my latest repositories, updates, and codebases here: git.cerffgursheel.party/cerff_gur_sheel
Software & Infrastructure Analyst | Focused on Problem Solving & Automation
I am a tech professional driven by a deep interest in understanding how systems operate underneath the hood — from core logic and algorithms to practical infrastructure setup and basic electronics.
I believe that understanding the fundamentals grants us the necessary flexibility to quickly learn and master any tool. I follow the KISS (Keep It Simple, Stupid) principle: code and architecture should be so clean and efficient that they explain themselves.
- Agnostic Approach: I don't bind myself to a fixed framework or label. When faced with a complex issue, I dig into the root cause, research the best approach, and implement an efficient solution.
- Infrastructure & Homelab: Passionate about self-hosting. I build and maintain my own home laboratory environment, managing local virtualization setups, service deployments, and data storage solutions.
- Linux & Systems: Strong familiarity with Linux environments, focused on what actually matters: shell scripting, user/permission management, system automation, and virtualization utilizing Proxmox VE.
- Practical Versatility: Experienced with Robotic Process Automation (RPA), network configuration, systems troubleshooting, and hardware diagnosis/maintenance.
Here are the key projects that represent my practical experience, problem-solving skills, and a bit of my journey:
- Cerffy (Music Streaming App): A personal streaming platform connected directly to a self-hosted Navidrome music server. Currently handling the backend logic, infrastructure integration, and music library synchronization.
- AVL-Tree: A pure implementation of an AVL Tree built after a university challenge where the professor claimed "no one would be able to code it" and jokingly promised a barbecue to whoever did. I built it, explained it line by line the next week, and I'm still waiting for that barbecue.
- PelandDealsAutomator: An RPA automation bot developed as a practical test for an RPA technical selection process, focusing on data extraction and task optimization.
- Running for the History: A digital game developed as a final capstone project (TCC), showcasing object-oriented programming, game loops, and resource optimization.
- Dino Lab: A horror game created under a strict deadline for a community game jam event (Toddyn's Game Jam).
- SokolTriangle_CPP: A foundational, low-level graphics script rendering a basic triangle utilizing the Vulkan API.
I don't look for quick, temporary fixes. When a problem arises, I am fully open to researching deeply, digging into documentation, and finding not just a solution, but the most efficient and optimized way to solve it. My goal is always to improve performance, facilitate system workflows, and automate repetitive tasks to streamline operations.
If you need technical labels, here is what I use to build and fix things:
C#, JavaScript/TypeScript, C, Python, Linux (Debian/RHEL/Arch), Proxmox VE, Networking, IT Security, RPA Automation, and Hardware Maintenance.
