Development & IT Consultation with Fernando R.

4.8 · 46 reviews

I’m a former Product Engineer at 360dialog, one of the largest WhatsApp API providers globally, alongside Twilio. As a Meta Tech Provider, I specialize in developing solutions for WhatsApp and have spent the last 10 years building software products for startups across Amsterdam, London, San Francisco, New York, Miami, and Berlin.

As a hands-on full-stack developer with a strong focus on the backend, I lead a small team of experts specializing in advanced, AI-powered WhatsApp solutions. Together, we design complex WhatsApp flows (including forms), integrate OpenAI and Claude for conversational chatbots, and build seamless integrations with tools like Calendly, HubSpot, Google Calendar, and Jira. Our goal is to streamline lead generation, boost sales, and automate internal operations.

To push the boundaries of what's possible, we even built our own WhatsApp automation platform: GoWaba (learn more at GoWaba.com).

Beyond the code, I’ve built, scaled, and successfully exited my own SaaS startup. This gives me a deep, practical understanding of the entire product lifecycle, from initial ideation to a successful exit.

I look forward to discussing your project!

WhatsApp Official API Developer | Meta Tech Provider | Agentic AI Expert

As a Software Engineer and Product Manager with 10+ years of experience, I specialize in building high-performance solutions inside the WhatsApp ecosystem. Recently, I led the engineering team at 360dialog, one of the largest WhatsApp Business Solution Providers (BSPs) globally, where I worked on production-scale WhatsApp implementations.

I also work closely with Meta teams and partners, including visits to Meta offices and participation in official events in São Paulo, Miami, and Montevideo, staying aligned with the platform’s latest capabilities and best practices.

Agentic AI + WhatsApp (Built for real operations)
WhatsApp is where business happens, but most “chatbots” stop at conversation. I focus on agentic systems: AI that can reliably take actions across your tools and workflows (CRM updates, approvals, scheduling, data capture), with the guardrails required for production use.

What I build (typical outcomes)
• Customer journeys: lead qualification, support automation, order tracking, appointment booking + reminders
• Internal workflows: onboarding, IT-service desk, approvals, secure document-data collection
• Integrations: CRMs, ERPs, custom APIs, designed for speed, observability, and scale

The “No Lock-In” Tech Stack
I provide the agility of modern AI-automation without locking you into a black box.

Modern infrastructure: AWS Lambda, Node.js, MongoDB Atlas
Full ownership: standard Node.js code that is exportable and remains your property
Compliance: designed for volume, GDPR-oriented, with multi-region deployment (EU-US) for data residency needs
AI-ready: integrate OpenAI or Claude via BYOK (Bring Your Own Key) for cost + data control

Global perspective & proven execution
My work is informed by the world’s most innovative tech hubs and events. I’ve participated in TechCrunch (California), SAP (Brazil), EXPO2020 (Dubai), Collision (Toronto), and Emerge Americas (Miami). In 2026, I was invited as a jury member at a Smart City hackathon in Valencia, Spain, where teams built solutions using the latest AI, OpenClaw-style agentic architectures, and WhatsApp as a primary channel.
Four years ago, I built a fully automated B2B startup and sold it for a 6-figure exit.

GoWaba (when speed matters)
GoWaba is the product foundation my team and I use to accelerate WhatsApp builds for global clients. It’s a WhatsApp-first, agentic-ready engine that bridges the gap between rigid DIY tools and expensive custom builds, reducing development time by ~40% while staying fully customizable.

Let’s build your vision
I offer a strategy session to review requirements, define the right architecture (including agentic AI where it makes sense), and map a clear timeline for your MVP or integration.
