I help businesses run smoother on two fronts: supporting and training their people, and building the systems those people actually use.
On the support and training side, I provide bilingual (English/European Portuguese) customer support, staff onboarding, and structured training programs — helping teams and clients understand new tools, processes, and services clearly in whichever language they're more comfortable in. I've also taught both English and Portuguese directly, one-on-one and in group settings.
On the systems side, I build the software that support and training actually run on. My flagship project, Casebook, is a full multi-tenant SaaS platform (Next.js, Supabase, Stripe) I built solo — from data model to live billing — to run my own legal and real estate practice. It's in daily production use handling real client cases, document workflows, and payments, not a demo. I also built Geniemix Academy, a bilingual language-learning platform, from the ground up.
Whether you need someone to train your staff, support your clients in two languages, or build the tool that makes both of those jobs easier, I bring all three together.

I help B2B SaaS startups reduce churn, improve customer retention, increase product adoption, and create smoother onboarding experiences that keep customers engaged long-term.
Most SaaS companies lose customers because onboarding feels confusing, follow-up is inconsistent, customer health is not monitored proactively, and support becomes reactive instead of strategic. I help you avoid that.

I support SaaS companies through proactive account management focused on customer engagement, relationship building, retention, renewals, and long-term customer success.
My account management support includes customer relationship management, customer check-ins and follow-ups and renewal coordination.
◆ Account Health Monitoring: I monitor account health to make sure that customers are achieving success while using the product. to make sure there's no surge in ticket, no usage drop and low adoption

I help agencies and service businesses transform GoHighLevel into the operating system of their company.
Not just another CRM.
A complete, secure business system.
Over the past several years I’ve built production-grade CRM environments that connect sales, operations, finance, AI and customer communication into a single platform that actually scales.
Most businesses already have the tools.
They have GoHighLevel.
They have CRMs.
They have automations.
The real problem is that everything works in isolation.
Leads get lost.
Teams duplicate work.
Managers have no visibility.
Revenue leaks between disconnected systems.
That’s where I come in.
I design CRM architectures that eliminate operational chaos and create scalable, hardened systems built around the way your business actually works.
Typical projects include:
• GoHighLevel CRM Architecture
• White-label multi-account environments
• Marketing & Sales Automation
• Revenue Operations
• AI Voice Agents
• System Hardening & Secure API Integrations
• n8n Automation (Python)
• CRM Migrations
• Twilio & WhatsApp
• HubSpot, Shopify, Airtable and custom integrations
Recent projects include:
• Multi-office GoHighLevel infrastructure for a US legal marketing company, including automated lead routing, commission management, reporting and client lifecycle automation.
• AI Voice Agents integrated with GoHighLevel, Retell AI, Twilio and custom workflows for lead qualification and customer support.
• Enterprise automation systems processing thousands of workflow executions per day using n8n, Python and AI, built with strict data security standards.
I don’t build disconnected automations.
I build secure systems that companies can grow on.
