Building products with strong engineering foundations.

I help startups ship reliable, scalable backend systems while keeping product outcomes front and center. From architecture and execution to mentoring and delivery, I bridge strategy and hands-on engineering. I’ve also built in blockchain ecosystems (Bitcoin & Ethereum), including ERC-20 tokens.

Let’s talk LinkedIn GitHub

Product

Roadmap alignment, discovery-to-delivery, metrics, and pragmatic prioritization.

Engineering

Distributed systems, APIs, data modeling, performance, reliability, and security.

Leadership

Team enablement, technical direction, quality bars, and sustainable execution.

About

Hi, I’m Jorge.

I’m a Product Tech Lead and Backend AI Engineer focused primarily on startups—helping teams move fast without breaking reliability. I also have experience building in blockchain ecosystems (Bitcoin & Ethereum), including ERC-20 tokens.

What I do

Architecture & system design Designing scalable services, APIs, and data flows with clear trade-offs and long-term maintainability.

Delivery leadership Leading execution: defining milestones, managing risk, and ensuring teams ship predictable outcomes.

Backend engineering Implementing critical paths, improving performance, reducing incidents, and raising code quality standards.

Team enablement Mentoring engineers, improving developer experience, and building processes that scale with the team.

Mentoring 1:1

From Mid to Senior & Senior to Tech Lead

I offer personalized 1on1 mentoring for Mid-level developers aiming to reach Senior level, and for Seniors looking to step up as Tech Leads. If you want to speed up your career, improve your technical leadership skills, or master system design, get in touch.

Note: Mentoring sessions can be conducted in either English 🇺🇸 or Spanish 🇪🇸.

Junie, más allá de Claude Code ¡en nuestro entorno de confianza! 🇪🇸

Agentic tools like Codex, Claude Code, or in this case Junie have completely changed the way we work. Three years ago, when the first LLM-powered chatbots emerged, we started "throwing code" through prompts. However, this wasn't always the most efficient approach — you had to copy and paste, while many routines could still be written and tested much faster with good typing speed than by copying them from ChatGPT.

All of this evolved with generative autocomplete systems in IDEs, until we made the leap to agentic IDEs like Claude Code, Codex, or Junie — capable of not just writing code in your project through prompts, but also installing dependencies, running tests, making commits, and even opening beautifully formatted PRs.

Claude Code is the current king, yet there is an alternative from JetBrains: Junie. An alternative that integrates seamlessly with IntelliJ and the entire JetBrains family, and at a very similar price to Claude Code, it offers powerful integration with the refactoring tools we're already used to.

In this demo we'll show you this alternative that you can integrate into your own workflows.
