Magento’s backend isn’t a theme — it’s an architecture.

Generalist developers handle the surface. I architect what’s underneath — the complex systems that actually run your business:

Complex Upgrades & Migrations

Upgrading a heavily customized store isn’t a button click. Custom modules, third-party extensions, and database schema changes all need to work together after every version jump.

Performance Architecture

Sub-second page loads on a 50,000-SKU catalog don’t happen by accident. They require the right caching layers, database indexing strategy, and server-side optimization.

Custom System Integrations

Connecting Magento to ERPs, CRMs, payment gateways, and shipping systems requires custom code that handles edge cases, retry logic, and data consistency — not just API calls that work in a demo.

Complex backends I’ve architected for B2B merchants.

Quoting pipelines, CRM integrations, headless recoveries — here’s what the work actually looks like.

Complex B2B Quoting & CRM Pipeline

The Challenge

Sales reps were processing quotes manually and deals were slow to close. They needed a quoting system deeply integrated with HubSpot CRM that off-the-shelf Magento solutions couldn’t handle.

My Solution

I built a quoting-to-deal pipeline where Magento quotes auto-generate HubSpot deals with stage tracking. I also architected custom post-order editing tools so reps could issue partial refunds and charge additional amounts after completion — critical for B2B where orders evolve.

The Result

Sales reps closed deals faster without hiring additional headcount. The quoting-to-deal pipeline became a core operational advantage.

Salvaging Headless SEO

The Challenge

An ambitious move to a headless PWA (React) architecture caused an SEO disaster — Google couldn’t index client-side rendered pages. Organic traffic dropped significantly.

My Solution

As project lead, I diagnosed the core rendering issue and directed the team to implement a server-side pre-rendering layer that served fully rendered pages to Google’s crawler while keeping the PWA experience for users.

The Result

Google indexing restored and organic traffic recovered. A hard-won lesson: I now advise clients against PWA for Magento — modern alternatives like Hyva deliver speed without the SEO risk.

I’m Eduardo, the certified specialist behind Remmote.

Since 2012, I’ve architected high-stakes Magento backend systems for U.S. and European clients — custom B2B quoting engines, complex ERP integrations, and headless SEO recoveries. I don’t patch front-end themes. I solve the deep architectural problems where your revenue actually lives.

The AI Edge: I’m actively building at the intersection of Magento and AI — four AI-powered extensions shipped in the last year, from automated SEO alt-text to LLM store assistants. This modern mindset drives every engagement.
