I'm a cybersecurity and coding enthusiast, mainly focused on developing new solutions to protect digital assets, but also interested in networks, cloud and physical infrastructures, microcontrollers and so much more.
Expertise
Conducting vulnerability scans to mitigate potential security risks in digital assets and networks.
Implementing and managing firewall rules to segregate network zones, according to a self-made Security Matrix.
Deploying and maintaining Intrusion Detection/Prevention Systems to detect and respond to cybersecurity threats proactively.
Utilizing Amazon Web Services (AWS) for cloud computing solutions, including deployment, scaling and management of applications and infrastructure.
Leveraging Tailscale Network and Cloudflare ZeroTrust platform to engeneer a full mesh network between different assets worlwide, with a zero trust approach.
Installing and utilizing Elastic Search to index, search and analyze large volumes of data efficiently for various applications.
Designing and developing responsive and user-friendly websites and webapps using HTML, CSS, JavaScript and related technologies.
Developing dynamic and interactive web applications using PHP scripting language for backend functionality.
Utilizing SQL languages to create, query and manage relational databases containing structured data.
Leveraging Python programming language for versatile applications including automation and scripting.
Programming and prototyping IoT projects with Arduino microcontrollers. This includes developing libraries, but also designing custom PCBs.
Adopting Proxmox to deploy a virtual infrastructure, composed of LXC containers and Virtual Machines.
Open Source
An Arduino-based system that enables remote start for BMW F30 vehicles by sniffing CAN bus messages via an MCP2515. A triple-click on the keyfob lock triggers the engine start sequence. Involved detailed reverse engineering of CAN bus traffic and car wiring. An unpublished evolution runs on a custom PCB with SMS support via LWSim800.
A lightweight Arduino library for the SIM800L GSM module, focused on SMS functionality: send, forward, check, read and delete messages. Designed for maximum stability in resource-constrained environments, it avoids dynamic memory allocation entirely, using a fixed-size data structure throughout.
