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 An older method for moving data around the Internet; superceded by more modern methods.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. |
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.
