ZNAS LLCFreelance
17 years engineering systems at scale and helping small to large businesses with their technology goals.
I build the systems that organizations depend on to operate.
I'm Jose Sanz, founder of Znas LLC and co-founder of Visionarys. For over 17 years I've engineered and architected production software across healthcare, airlines, finance, and telecommunications.
System Architecture
Designing distributed systems, microservices, and public APIs that handle real production load. From whiteboard to deployment across healthcare, airlines, finance, and telecom.
Full-Stack Engineering
End-to-end development across mobile, web, IoT, and blockchain. 17 years of shipping production software across multiple stacks and industries.
AI & Emerging Tech
MIT-certified in AI Business Strategy. Building AI-powered applications, intelligent agents, and developer tooling. Passionate about bridging the gap between cutting-edge AI research and real-world product engineering.
Startup Leadership

Software Engineer
Afni
Started my career building user-friendly applications for call center workflows. Engineered OOP-based software frameworks, conducted research on emerging technologies, and developed proofs of concept for new systems.
Applications Developer
Amadeus IT Group
Built enterprise applications within the global airline distribution and passenger data ecosystem at a leading GDS provider. Worked across high-compliance environments supporting both commercial aviation and regulated government data requirements, delivering production systems on distributed .NET platforms.

Co-founded Visionarys to pursue the next chapter in AI-driven software and startup ventures. Combining 17 years of engineering depth with strategic product leadership.
CoPresent
REV: 01Working alongside AI today means bouncing between a chat app, a data tool, and a meeting — agents never share the room, humans never see the data, and context gets lost between tools.
A real-time workspace where humans and AI agents share one room — voice, video avatars, and an interactive graph canvas on a single presence layer everyone reasons over together.
Teams run mixed human-and-AI sessions — planning, research, data exploration — in a single space where every participant sees the same data and hears the same conversation.
MemQL
REV: 02AI-native applications stitch a database, vector store, workflow engine, AI gateway, and voice stack together by hand — each with its own schema, query language, and failure modes.
A distributed time-series memory graph that collapses AI providers, event-driven automations, and real-time voice into one DSL — concepts, queries, mutations, and workflows declared side-by-side and executed across specialized nodes.
Product teams ship voice agents, cognitive workflows, and multi-agent spaces in weeks instead of quarters because the DSL replaces the integration glue their competitors still hand-write.
asyncapi-codegen
REV: 03Distributed systems teams waste weeks hand-writing async messaging boilerplate for every new service.
Go code generator that reads AsyncAPI specs and produces production-ready client and server code automatically.
Open-source tool eliminating manual boilerplate. Ships messaging infrastructure 10x faster.
t4t: Tag-based Filesystem
REV: 04Hierarchical folder structures break down as projects and contexts multiply across a developer's filesystem.
Tag-based CLI that replaces rigid folders with composable, searchable metadata. Think tags, not trees.
Open-source. Enables cross-cutting organization without duplicating or moving files.

Jose is an extremely competent AI developer. In a very short time, he put together architectural documentation, determined which components each team member could take on and quickly delegated work. After development was complete, he also jumped into presenting to a community of software developers and technologists as part of an AI-focused workshop series.
