Ventrue Labs is where Ventrue Technologies writes down what it learns. It is a lab notebook, not a marketing channel: each post is a write-up of real work — an idea that became a project, an experiment, a debugging finding — structured like a lab report. Context and question, hypothesis, method, results, takeaways. We publish the failures too, because a negative result you can trust is worth more than a success you can't reproduce.

Who writes this

I'm Erick Escobar, a senior backend engineer and solutions architect, and the engineer behind Ventrue Technologies. I do the work most people avoid: modernizing legacy enterprise systems and integrating them with modern cloud — without breaking what's already running in production.

A sample of the kind of problem I work on (clients generalized):

• Migrated an enterprise IBM i / AS400 core to .NET using the Strangler Fig pattern with an Anti-Corruption Layer — incremental, no big-bang cutover (~30% productivity gain).
• Built a centralized M2M / JWT auth microservice (OAuth2/OIDC) that cut application-integration time across a microservice estate by ~70%.
• Wired QR / digital-wallet payments over RabbitMQ with idempotency and reconciliation for an event-driven field-collections flow.
• Shipped cloud-native microservices (CQRS, Clean Architecture) on Azure with meaningful availability gains.
• Built the hardware side end to end — firmware (ARM/AVR) → custom PCB → embedded Linux → cloud — from an electronics-engineering background.

The stack behind the posts

.NET / C#, Next.js / React, Node, Python, Flutter; PostgreSQL; Azure and AWS; Docker, Kubernetes, Proxmox; event-driven integration with RabbitMQ, IBM MQ and Kafka. Most of what you'll read here comes out of those tools meeting a real constraint.

Why publish it

Writing the work up as a lab report forces honesty: you have to state what you expected, what you actually measured, and what you'd change. That discipline makes the engineering better, and the notes useful to anyone hitting the same wall. Based in Ecuador (UTC-5), bilingual EN/ES.
