Mike’s Place


This is not your typical résumé. First things first: this page is the only source for this document. Remember that a résumé is a document and that documents are subject to copyright. There is no PDF version of this résumé. Just this one right here, at https://mike.trausch.us/resume/.

This page is just the tip of the iceberg—a broad overview. There are (or rather, will be; this page is still a work-in-progress) links throughout to additional details, portfolios, examples, and references. By the time you’re finished reading through this, you should know pretty well whether or not I can do the work you need done.


Systems and application programmer capable of designing, coding, analyzing, and modifying both linear and asynchronous systems. Fluent in low-level concepts such as interrupt handing on “bare metal” systems, highly fluent in POSIX® (in particular Linux® and FreeBSD®), versatile with most POSIX®/UNIX® systems both in terms of usage and programming. Capable of interacting with both documented and undocumented binary file formats, such as for data recovery or migration purposes.


This is a set of statistics about myself, as pertains to work.

This is a list of protocols with which I am familiar enough to reason about. As a point of note, I can generally learn any new protocol in as long as it takes to read the RFC document(s) which define it, plus a little time to study or experiment with it (depending on whether it is a new or existing protocol).

Name Description
CGI Common Gateway Interface, a protocol for interfacing between Web servers and the standard I/O of a program which provides a service.
DHCP Dynamic Host Configuration Protocol (both v4 and v6).
DNS The Domain Name System protocol, which currently powers name resolution for most of the Internet.
FTP File Transfer Protocol. An older method for moving data around the Internet; superceded by more modern methods.
IP Both IPv4 and IPv6, including routing protocols and multicast.
HTTP Hypertext Transfer Protocol, used for most of the traffic carried by the Web.
IMAPv4 An access protocol for electronic mail.
IRC Internet Relay Chat, an older protocol used for communications on the Internet.
MIDI Protocol used for the automated control of instruments, including synthesizers.
NNTP The protocol powering Usenet (“netnews”).
POP3 The Post Office Protocol (v3). A formerly popular method for accessing electronic mail messages, largely replaced by IMAPv4 and Web mail access.
SCGI A more modern replacement for CGI, using netstring. Limited to a single request per connection.
SIP A protocol most commonly used for VoIP call control functions, although it has other uses as well.
SMTP The protocol used to relay an electronic mail message to its destination.
SSH2 Secure session protocol providing a multiplexed connection to a host system, allows for the management of remote processes and terminals as well as remote filesystem operations.
TCP The protocol which provides a virtual digital bidirectional communications channel for most network applications.
Telnet An older protocol for remote terminal sessions over the network. Generally superceded by SSH.
TLS Transport Layer Security (also incorrectly known as SSL). Provides encryption and authentication services.

File Formats

To be completely honest, I know more file formats than I can list here, and I have likely forgotten even more than I know right now. File formats are rather easy for me to grasp and work with, even when they try to do clever things like use variable-length integer encodings (the Bitcoin blockchain and compatibles) or have broken or missing indexes.

This also makes data recovery easier for me, as I can easily work around what’s missing once I understand the context around it.
