Randy formalized his genealogical work starting in December 2008 with the creation and use of his online DB and wiki; the precursor to this site. He developed experience with online sites and pages in support of industry groups and non-profits starting in 1988. (Yes, this is even before the creation of the URL and WWW / HTML standard!) His impetus into more formally studying genealogy was the loss of several close family members and the perceived desire to capture his parents history before he lost them and all their history for his descendants forever. His mother is a first generation immigrant with over 50 first cousins; each of which she knows, their spouses and kids. His father's family and history is what has created the most challenge.

Randy expanded into Genetic Genealogy in May 2011 with a personal yDNA STR test. He now manages well over 50 test kits with near and distant relatives; and even some simply a part of this H600 project here. Kits include testing everything from Autosomes w/ X, yDNA STR and SNP, Mitochondrial DNA and now nearly a dozen WGS. He has delved deeply into the testing process, the biology of DNA inheritance in cells, and vendor tools that help study and manipulate test lab results. Randy manages or helps manage five family DNA projects (four on FamilyTreeDNA) and manages an additional two surname projects. He founded the Guild of One-Name Studies search into the surnames covered here as well. To date he has not sought any professional certifications nor speaking engagements; although has been encouraged to do so.

Professionally, Randy was a trained and practicing Computer Engineer and spent most of his professional life in Silicon Valley, California. See his Sevni consulting page for more information there.

Randy has spent his career creating online help sites for various groups in the industry or non-profits he has helped with. His first was a dialup Bulletin Board System (BBS) setup in 1988 to support his newly founded VHDL Users Group. This became on online, "internet" resource in 1993 when he registered the name "vhdl.org", bought a C block of IP's from Stanford's BarrNet, setup a dedicated T3 line, and purchased a SunStation server. Soon after, he expanded this effort and renamed it to eda.org and managed the ever expanding activity there for ten more years. The more informal VHDL Users Group would become the industry backed VHDL International as Randy switched gears after Silicon Valley burnout.

Randy would soon got back into non-profit, industry support though with his new found passion of soccer and soccer refereeing. This quickly led to several sites and servers where he now "leased" share space from established server providers (having given up his machine at Stanford University). One of these sites led to his first introduction to using Wiki's and incorporating the TikiWiki software: AYSOWiki,org. The other popular one (socref.net) became a worldwide resource for many professional soccer referees. He also setup and ran the ayso43.org and then ayso2a.org websites as he advanced in management of the local youth soccer leagues. Spending much effort researching and documenting the deep history of these first branches out of the core founding group in Los Angeles.

In parallel, Randy had set up a personal, home site of Modiharr.com which doubled as his wife's new profession and held family photos and such. When starting genealogy in 2008, he loaded up tools such as PHPGedView, TikiWiki, Menalto Gallery and more. To help with generalizing this genealogy effort more, and due to other support hosted out of the family site, Randy created the mycuz.us site in 2011 and moved his genealogy work there. This h600.org site followed as a natural extension in early 2016. With a shift in focus to using WGS in 2019 and a takeover of support and development of the new, quickly released WGS Extract in 2020, Randy created the WGSE.io and WGSE.bio sites to help manage those efforts. Along with several Facebook groups to lend further, online support.
