Welcome

Welcome to my website, where I happy to share a journey of my experiences. What started as computer repair work evolved into deeper expertise in workflow automation, computer networking, APIs and small "infrastructure" management. I use tools like n8n, Proxmox, and Linux to solve repetitive tasks into automations. On this site, you'll find the projects, skills, and experiences that helped to expand and learn.

Work Experience

IT & Repair Technician Mar 2023 — Present
Started in a hands-on hardware role refurbishing, repairing, and erasing laptops (Windows/macOS) for business clients. Maintained inventory records and quality control through internal asset management systems. Expanded into the IT team — handling laptop setup, onboarding, and troubleshooting using Datto IT Glue and Autotask. Developed working knowledge of networking protocols (TCP/IP). Deployed an n8n workflow to automate label printing based on Monday.com and eBay status updates via webhooks, reducing manual input and increasing efficiency.
Sales & Repair Technician Aug 2019 — Mar 2023
Specialised in repairing, refurbishing, and selling Apple hardware to a diverse customer base. Provided customer support via phone, in-person, and email. Delivered macOS support both remotely and on-site, assisting users with troubleshooting and system optimisations. Conducted data recovery services, successfully retrieving lost data for clients. Gained practical experience in micro soldering, performing motherboard repairs to extend device lifespan.

Web Applications & n8n

While working at my recent job, I have spent my spare time to learn some automation skills. Due to long term of my employment there, I started to notice which my tasks can be automated with help of n8n and APIs. Bellow you will see examples of my workflows that I implement while working at my recent employment.

Integrating Bit Raser with monday.com

Created an automation using n8n to fetch specifications of each device from Bit Raser erasure reports. Assets are recorded inside the monday.com table. If a data erasure was done on the asset, monday.com will send a trigger to n8n. n8n will perform webhook calls to Bit Raser API. Finally, the n8n workflow will extract required device information and will fill out information inside monday.com table. This reduces manually typing specifications monday.com and reduces human error. To achieve this workflow, the input values are taken from serial number or monday.com item ID number.

Internal web applications

This is where I began using Claude Code for coding. I originally, do not have great programming skils, however using Claude Code with VS Code I have managed to come up with 2 internal web applications for my workplace.

Slack Bot

My api knowledge actually started with this project. SellerCloud is a platform where you can push your items to various e-commerce platforms. SellerCloud was used to update information and price of the item and you can list an item to ebay using SellerCloud. Due to my experience on how manually you have to update on each item, I decided to use n8n and created a n8n workflow which communicates with a slack bot. The user can insert a SKU for specific item, n8n does API calls to Sellercloud to check what product description is. Using product description an AI, using prompt engineering, will figure product weight and dimmensions. Builds an eBay title and eBay description. This has reduced human input and time for each listing. Additionally, using this workflow, it can upload marketing images, which are repetitive for each product.

Early Years

Education

Bsc Computer Science & Msc Computer Networks 2017 — 2024
My Master of Science in Computer Network Engineering gave me hands-on experience in TCP/IP, network design, and Linux server administration. For my Master's Project, I built a web-based remote-controlled air conditioner — designing and hosting an Apache server on a Raspberry Pi and integrating it with custom hardware to enable remote control over the web, which gave me practical experience bridging software and physical systems. I also hold a Bachelor of Science in Computer Science, where I developed fundamental programming skills in Python, Java, and C through a variety of projects covering application development and algorithms.

Air Conditioner Project

I have mentioned this about inside my educational background summary. I actually enjoyed doing this project because I used of the shelf parts and I was salvaging or parts from Apple's Mac Pro towers that came out from 2000s. I learned about peltier modules and managed to create a circuit that is capable to adjust power input. I used Raspberry Pi to read tempreture sensors which were able to show inside Apache Hosted web page.
