Welcome to Luka's self-hosted website!
Here I talk about my experiences with tech, as well as present my career path, education, projects, and hobbies.
Check out my blog, as well as my personal milestones, which lists my completed and active goals for the future.
Projects
EMBArk – Django-UI for Siemens Energy
Open source university project in cooperation with Siemens Energy: Further development of a Python web UI for managing firmware analyses via SSH workers in a team, with a focus on agile methodologies.
Our student team had multiple weekly meetings in which we discussed the future of the project and prioritized tickets. We also had mandatory reviews for each pull-request which helped uphold a high standard of code-quality.
Server administration of network systems with NixOS
Declarative configuration & administration of fault-tolerant servers with Cloudflare, Mesh VPNs, nginx, ZFS, SSHFS, monitoring, cloud printing, email server, and proxy. With a focus on IT security, reliability, and best practices.
This is currently my main hobby. Started in 2024, now I rely on many of these services. I also run a server for my parents which they use for media storage as well as QoL improvements like cloud-printing. This server is also used as a remote backup.
With this, my journey to degoogle my life and rely less on external services has been a success.
File archiver in C
Archives/extracts files in its own format using Huffman coding. Implements multi-stage compression for a minimal file size. Programmed without external dependencies or libraries.
This was done to learn about Huffman coding and different file compression techniques. I also had to come up with my own format to overcome the challenges of storing data in bits instead of bytes (as per the algorithm).
Career
Junior Backend Engineer Internship – Talkpal Inc.
Scrum-based backend development with NestJS & microservices: optimization of Redis queues for email scheduling, endpoint conversion in Swagger, debugging with PostgreSQL, etc.
Here I had first-hand experience in how mid to large teams operate. I helped with bugfixes, modularized endpoints, updated the documentation, and optimized Redis queue sizes of mails.
Information Technology Support Specialist – Cura Unternehmensgruppe GmbH
Support with network and user administration, hardware maintenance and management, automation, and documentation in the IT field.
Here I gained invaluable people-skills, as well as further developed my logical reasoning. Problems in IT seem often unexplainable, but the methodology of fixing it is often quite similar.
I also worked on repairing/repurposing decommissioned hardware as well as automating some chores my colleagues had to do e.g. user account creation using a PowerShell script that reorders a CSV, and creates new fields based on hashmaps.
