My core area of expertise is real time communications (VoIP, Video, WebRTC etc), worked with open source and commercial vendors (Cisco, Avaya, Oracle) as well. 10+ years supporting infrastructure comprise of mainly Cisco gear (routers, switches, firewalls).
I am a long-time [open-source contributor and Linux enthusiast](https://www.archlinux.org/people/developer-fellows/#schiv). In the past I spent most of my time staring at black screens with green text scrolling endlessly for hours and days. I am now a practitioner of [Knowledge Science](https://www.infoworld.com/article/3448577/who-should-be-responsible-for-your-data-the-knowledge-scientist.html), an emerging subdiscipline of Computer Science allied with the goals of [explainable](https://www.forbes.com/sites/forbestechcouncil/2019/12/30/explainable-ai-the-rising-role-of-knowledge-scientists/#395937a2603f), ["semantic"](https://www.poolparty.biz/semantic-ai/) artificial intelligence (AI). With a background in the [Semantic Web](https://www.dataversity.net/semantic-web-and-semantic-technology-trends-in-2020/#) and traditional [symbolic AI](https://en.wikipedia.org/wiki/Knowledge_representation_and_reasoning), I am a graph database specialist fully invested in data modelling and programming with semantic technologies.
While as a Computer Scientist I am inclined on research and development (R&D), nothing gives me more satisfaction than building or leading a software technology project from inception to production, especially so at the bleeding-edge. I regret that I may be time-constrained, but you are welcome to check in with me for quick consultations.

Howdy! I'm a solo entrepreneur and software engineer that's been working with web-based technologies for the better part of the last 30 years. I have over ten years of experience working with Python/Django software systems. I've built projects from scratch, scaled them to tens of thousands of users, and rescued projects with disorganized, confusing codebases. I've built and managed software teams focusing on efficiency and reliability.
*Coder*, long time *hacker* and infosec pro, into *exploit dev* and *security tool development*. I love everything computers, and I love to help people figure out how to do what they need to do in tech!
I've been developing software professionally for 22 years (and recreationally for many years before that) across a number of diverse business domains. I pride myself on clean, maintainable, production-ready code based on sound, thoughtful designs.
