The Team Behind Plexara
Product of Deasil Works, Inc.
You Get the Team, Not Just the Software
Plexara is built and operated by Deasil Works, an engineering company that has been shipping software and running real infrastructure for enterprises for over twenty-five years. The principals and core team have worked together since the 1990s, across entertainment, retail, logistics, automotive, and manufacturing.
That continuity is the point. The thesis behind Plexara came out of decades of running real data platforms for real customers, not from a whiteboard. The people who formed that thesis are the people who maintain the platform today.
When you adopt Plexara, you are not handed a login and left alone. You get direct access to the people who built it: the founders, the product lead, the engineers tuning the AI integration, and the team that keeps the infrastructure running.
The same hands that shipped the platform are the ones who help you put it to work. That is what a fully managed product backed by an engineering company is supposed to mean.
The People
The Core Deasil Works Team
Plexara customers work directly with the founders and the engineers responsible for product, AI integration, education, and infrastructure.
Jeff Masud
Co-founder
Jeff has been building software for more than twenty years, from a single clear vision through the complex business logic that enterprises actually run on. He founded Deasil Works to do hands-on engineering for companies that need systems built right, and he co-founded Plexara to turn decades of that work into a governed integration layer any AI agent can use.
CEO, Deasil Works
Craig Johnston
Co-founder
Craig has led software and creative engineering teams at Deasil for over two decades, across entertainment, retail, logistics, and manufacturing, and has written extensively on Kubernetes and cloud-native architecture. He sets the technical direction for Plexara: open standards, composable architecture, and no black boxes anywhere in the stack.
CTO, Deasil Works
Dan Mehta
Product Management
As a senior project manager and QA engineer, Dan specializes in developing and executing exploratory and automated tests, the discipline that keeps complex platforms honest. On Plexara he owns product management, turning what customers need into a roadmap and making sure every release behaves the way the documentation says it does.
Sr. Project Manager and QA Engineer, Deasil Works
David Elsensohn
Integration and Education
David has worked at the intersection of online development and music for over twenty-five years. He leads integration and education for Plexara, helping teams connect their data sources and learn to get real work done with a governed MCP server, so the platform lands as working practice rather than a slide deck.
Lead UX/UI Engineer, Deasil Works
Jonathan Garcia
AI Integration, Tuning, and Development
Jonathan leads senior backend development at Deasil, designing and building the services and APIs the platform runs on. For Plexara he focuses on AI integration, model tuning, and development: the work of making frontier models fluent in a customer's business through enrichment, memory, and retrieval that holds up in production.
Sr. Backend Development, Deasil Works
Mikel Arvizu
Infrastructure and Support
Mikel keeps the metal running. He manages the bare-metal hardware, networks, and Kubernetes clusters behind Plexara across Deasil's United States facilities, and he is the person on the other end when something needs attention. To him, infrastructure and support are the same job: the platform is only as trustworthy as the systems underneath it.
