Eric Barreto

I’m a Software Engineer focused on designing and shipping scalable systems, currently working with healthtech and fintech products. I work mainly with modern JavaScript/TypeScript stacks and specialize in real-time features, systems architecture, and full product integrations.

I’am leading a squad of 4 engineers, driving discussions around technical priorities, realistic deadlines, and solution planning. I often take the lead in breaking down complex problems, aligning deliverables with business goals, and ensuring a high standard of execution across staging and production environments.

I have deep experience integrating Meta’s official APIs from scratch — including full implementation of WhatsApp Cloud API (Embedded Signup, webhooks, message handling, agent routing, compliance) and Instagram Graph API (user interactions, automation, and message workflows for CRMs).

I believe that strong teams are built on clarity, empathy, and collaboration. I value honest feedback, enjoy exchanging ideas, and constantly seek to improve—not just as an engineer, but as a teammate. I care about the people I work with, and I'm always open to learning from others while sharing what I know.

🛠️ Main technologies:
- JavaScript & TypeScript
- React / Next.js
- Angular JS
- Node.js / Express \ NestJS
- Sequelize / TypeORM / Prisma / PostgreSQL / SQL
- Redis / Socket.IO
- MongoDB
- Meta API's (WhatsApp, Instagram)

I care about clean architecture, well-structured codebases, collaborative teams, and delivering real value through tech. Currently focused on solving real-world problems at scale.

Always learning. Always shipping.
