In their words
Some feedback I received on LinkedIn
Salim stands out as one of the best managers I ever worked with, exhibiting a rare blend of deep technical understanding with a genuine commitment to nurturing his team.
Razvan AlecsandrescuProduction Engineer · Meta
Salim's extensive technical expertise across various fields, coupled with his adept communication skills, greatly contributed to the team's understanding and alignment with his vision.
Breno LeitaoProduction Engineer · Meta
Salim owns an extraordinary profile as CTO of SdV. His knowledge of the datacenter market, Tier-1 and IP among others is exceptional.
Miguel VilladaSr Consulting Engineer · Arbor Networks
Salim is a bright guy. Not the kind of average bright guy, he is a real bright, clever, smart engineer, with a very high focus on efficiency. He has turned SdV in a real Internet powerhouse.

Projects
Tools built over the years, because what I needed didn't exist.
Hex Packet Decoder
A free, AI-powered packet decoder trusted by engineers at Broadcom, Cisco, Fortinet, Juniper, NASA, and universities worldwide. Started as a personal tool and became a community reference.
Geo Traceroute
Accurate geolocation of traceroute hops on the Internet is an open problem. This is an approach using a network of 300+ nodes and deep learning with PyTorch.
Postfix GLD
A lightweight standalone greylisting daemon written in C for postfix, available on Ubuntu, Debian and many other distributions.
Docker HCD
Docker was missing some high availability features I needed, HCD is a daemon that restarts unhealthy containers, downloaded more than 10,000 times.
BGPMap
Standard looking glasses were missing fanciness, I opted for a real time graphical BGP paths visualisation.
Visualising RIPE ATLAS Anchor Measurements
An article on how to leverage RIPE ATLAS nodes to enhance your network observability, published by RIPE Labs.
GPU GLSL Shaders
I always wanted to code GPU GLSL shaders as the programming logic is quite unique and challenging.
Three.js old school demos
As a former Amiga scene democoder, I recoded some old school demos using WebGL and Three.js.
L2WH Lineage II Network Sniffer
(2004-2009)
Reverse-engineered Lineage II's encrypted network protocol with zero documentation from NCSoft. Real-time packet capture, decryption and parsing to extract mob data, drop rates, item stats and XP metrics. Used by thousands of players worldwide, tolerated by NCSoft, and commercially acquired at end of life.
ClassAction for AmigaOS
(1994-1998)
ClassAction is a file manager for AmigaOS, written between 1994 and 1998, it was quite popular by that time.
