Senior Cloud Architect & Consultant
Based in Miami. I build practical generative AI applications, especially for document processing, search, and complex business workflows. I spend a lot of time on the systems around the models — durable orchestration, distributed services, and cloud infrastructure, mostly on Azure. I also have years of experience building identity platforms and working with applied cryptography, open standards, and secure systems.
A free, open-source Mac menu bar app that lets ChatGPT and Claude talk it out. Give it a topic and Errol carries every reply between the two desktop apps while you watch, so each assistant keeps its own memory, tools, and settings. It drives the apps through macOS Accessibility the way you would, so there are no API keys, no account, and no server in the middle.
Role: Creator · Solo developer
Nutrition tracking through conversation. Describe a meal in Claude or ChatGPT and Ziva resolves it to USDA food data with a detailed nutrient breakdown.

Neural handwriting synthesis for web and mobile. Longhand turns typed text into expressive, human-looking handwriting.
Role: Creator
A self-hosted, read-only dashboard for understanding durable workflows in DBOS Transact applications. Point it at Postgres or SQLite and inspect workflow state without app-side wiring.
Role: Author
A digital credential wallet where your passkey is the wallet — no seed phrase, no server-side custody; the entire key hierarchy is derived from the passkey PRF. The live demo pairs the wallet with a DMV issuer and two age-checking verifiers, with a guided tour up the privacy ladder: OID4VCI issuance, OID4VP presentation, BBS selective disclosure, and in-browser zero-knowledge predicate proofs.
