Full-Stack Developer
I developed the software engineering and technological modernization at CEAR Latinoamericano. I designed and deployed an end-to-end ecosystem of 4 scalable web platforms that thoroughly transformed the institution's academic, sales, marketing, and lead acquisition operations.
The Ecosystem of 4 Platforms I Built
Each solution eliminated a critical operational bottleneck. Explore each technical case study:
CEAR Virtual Campus
Official online learning and exam platform with Niubiz payment integration, synchronized live lectures, 200+ concurrent student support, and RBAC administration.
Mailer System & Automation
Internal 1,000 emails/minute dispatch engine with BullMQ, SendGrid API, Unlayer drag-and-drop template builder, and real-time open and bounce tracking.
Internal CRM & RNP Lead Management
Internal platform to centralize and qualify +200,000 RNP procurement entities, featuring Marketing Manager task distribution to sales reps and Mailer feedback integration.
Continuing Education Web Platform
Public Next.js (SSR/ISR) website showcasing specialized JRD, Arbitration, NEC, and FIDIC programs, with integrated enrollment forms replacing WhatsApp outreach.
Key Pillars of Technical Responsibility
Fundamental engineering principles that guided my day-to-day work:
High-Availability Architecture & Backend
Design of modular, scalable APIs using NestJS and Express, relational data modeling in PostgreSQL optimized with Drizzle ORM, and asynchronous background job queues powered by BullMQ and Redis.
Modern Frontend & User Experience
Development of responsive interfaces using Next.js (App Router), TypeScript, and Tailwind CSS. Implementation of dynamic TanStack Table modules for heavy data catalogs and hybrid SSR/ISR rendering.
DevOps, On-Premise VPS & Data Sovereignty
Comprehensive containerization with Docker and Docker Compose, provisioning of CEAR's On-Premise VPS, network hardening, SSL/TLS certificates, and automated scheduled backups.
Digital Transformation of Business Workflows
Replacement of manual WhatsApp and spreadsheet processes with a unified pipeline connecting public web enrollment, CRM with task supervision, and automated bulk email prospecting.
