Included below are links for a few work samples, PRs, side projects and other public, programming-related stuff. This list is biased towards Free Software work as that can be freely linked, but I have worked on many closed source projects for clients, and would love to discuss my experience over a call.
Porting Fee Estimation to Decred
Related Technologies: Golang, Cryptocurrencies, Bitcoin.
This was my first new feature for Decred’s dcrd full node implementation: a port of the original (C++) code for fee estimation done in the Bitcoin Core software.
Decred Split Ticket Matcher
Related Technologies: Golang, WebAssembly, Distributed Systems, Network Programming.
One of my major contributions to the Decred ecosystem: a trustless and permissionless way for multiple people to purchase shared Decred voting tickets, which are used for the platform’s governance.
Implementing i18n in Decrediton
This was one of my first major contributions to Decrediton. This PR switches the whole app to be translated. The internationalization was implemented using react-inl and the actual translation is performed at transifex.
PyPaperBak - Paper Backup
Related Technologies: Python
This was a quick side project I wrote from start to finish, showing how to backup and restore information from paper backup using QR Codes.
Bugfix to Firebird’s PHP Driver
Related Technologies: C, PHP, Firebird
Back at Gigatron when I started writing the first web apps linked to the legacy firebird database, I encountered a few bugs in the PHP driver and had to fix them to be able to proceed.
Interactive PID tutorial
This is an interactive, graphical tutorial on how PID controllers work. Back when I developed the software for CNC machines, I had to constantly teach support staff how PIDs worked, so I wrote a small interactive tutorial. Source available at Github.
Qubes + Borg Backup
Related Technologies: Shell Scripts, Borg, QubesOS
Having automated backups is essential for any professional. This is a small tutorial, along with a few sample scripts, on how to setup backup using Borg Backup and Rsync.net for a QubesOS install (my current OS of choice).
