David Christian Liedle is a software engineer, developer advocate, educator, and technical leader with more than 28 years of professional experience. Beginning as a self-taught programmer in childhood, David has built a career connecting technology with people—designing and developing software, leading engineering teams, teaching developers, and helping organizations build thriving technical communities.
His experience spans software engineering, technical product management, consulting, and Developer Relations, including senior roles at Cisco, Filestack, and eZ Systems (now Ibexa). As a Senior Developer Evangelist at Cisco, he supported the Webex developer ecosystem and coordinated community initiatives including the Webex Hackathon. His career also includes engineering management, technical mentorship, public speaking, and helping developers adopt new technologies.
Beyond his professional roles, David is an active creator of open-source software and experimental development tools, including NMOX Studio and NMOX Server. His work reflects a longstanding belief that great technology should empower people to create, learn, and collaborate. The timeline below traces his journey through decades of engineering, entrepreneurship, education, and developer advocacy.
While on long-term disability leave from full-time employment, David has remained actively engaged in independent software research and open-source development. His projects include NMOX Studio, a NetBeans-based development environment; NMOX Server, an experimental multilanguage metaframework built around composable X objects; and unit, an experiment in self-replicating distributed systems.
David is also exploring AI-assisted software engineering, autonomous coding agents, and new approaches to human–AI collaboration. He continues to learn, experiment, build, and share his work with the developer community, with the hope of returning to professional employment when medically able.
David's medical leave from Cisco continued through 2024, during which he transitioned to long-term disability. His focus during this period was on recovery rather than full-time professional employment.
David took medical leave from his position at Cisco during 2023, initially under FMLA and short-term disability. This marked an interruption in his professional career while he focused on medical treatment and recovery.
David has been a Senior Webex Developer Evangelist at Cisco since July of 2021. See the Webex Hackathon he led.
As a Senior Webex Developer Evangelist at Cisco, David helped developers understand, adopt, and build upon the Webex platform, including its APIs, bots, integrations, embedded applications, and SDKs.
His work brought together technical education, developer advocacy, and community engagement. He helped establish the dedicated Webex for Developers community forum and coordinated the 2022 Webex Apps Hackathon, supporting participants through team formation, project submissions, judging, and the announcement of winners.
These initiatives reflected his commitment to building welcoming, productive developer communities and helping developers turn ideas into working software.
Through his independent DavidCanHelp consulting practice, David provided remote software development and technical services to clients, including mobile application development, full-stack web development, consulting, and technical writing.
In July 2021, he accepted a position at Cisco as a Senior Webex Developer Evangelist, bringing together his extensive engineering background with his passion for developer education, advocacy, and community building.
David traveled to South Africa to help establish a web development academy intended to introduce students from diverse backgrounds to HTML, CSS, and JavaScript.
Unfortunately, the emergence of the COVID-19 pandemic disrupted the initiative before the academy could fully launch. The team was forced to abandon its plans, and David returned to the United States under difficult circumstances.
Although the academy never opened, the effort reflected his longstanding commitment to making software development accessible to new learners and helping people develop practical technical skills.
In February 2019, David founded DevRelopers.io after the CEO of Filestack invited him to continue providing Developer Relations services on a contract basis.
What began as an independent consulting arrangement expanded to include additional clients, with services focused on developer advocacy, technical education, community enablement, and developer engagement, particularly within the emerging Flutter ecosystem.
David playfully described this consulting model as "Developer Relations as a (Human) Service"—bringing experienced technical advocacy and a personal touch to organizations seeking stronger relationships with their developer communities.
David transitioned from Senior Technical Evangelist at eZ Systems (now Ibexa) to Chief Evangelist at Filestack, reporting directly to the CEO.
At Filestack, he brought his background in software engineering, developer education, and technical communication to a leadership role focused on developer engagement, technical advocacy, and growing the company's relationship with its developer community.
He worked remotely from his home office in New York City, collaborating with colleagues at Filestack's headquarters in San Antonio, Texas, and participating in the company's developer outreach and strategic initiatives.
At eZ Systems (now Ibexa), David transitioned from Technical Product Manager to Senior Technical Evangelist, moving from a primarily product-focused role into developer education, advocacy, and community engagement.
His work at eZ included building and deploying the first version of eZ University, developing technical training materials, producing educational videos, and representing the company's technologies at developer conferences and industry events.
His international speaking and training engagements included appearances in Austria, Croatia, France, and Spain, helping developers, partners, and customers understand and make effective use of the eZ platform.
David began his professional software development career in 1998, opening an independent web development studio in Central Georgia and incorporating his business in 2001 as Media Dust Corporation. His early career combined software development with journalism, publishing, and multimedia production, including serving as director of the Marshallville Public Library, working as a newspaper reporter and webmaster, and producing the weekly dotMEDICAL television program.
As the web industry matured, David expanded into software architecture, research and development, technical consulting, and engineering leadership. His work spanned startups, healthcare and pharmaceutical companies, educational institutions, government agencies, and major enterprise organizations.
Notable accomplishments included developing certified electronic prescribing systems, designing APIs and developer tools, leading an eight-person development and QA group as an R&D Manager, and helping organizations modernize their software architecture and development practices.
His engineering assignments included projects for Charter Communications, the United States Air Force, the University of Advancing Technology, and numerous technology and healthcare companies. Across these engagements, David combined hands-on engineering with technical mentorship, architecture, product development, and responsibility for delivering working solutions.
In 2016, David joined eZ Systems as a Technical Product Manager, beginning a new chapter that increasingly brought together engineering, product strategy, education, and Developer Relations.
