Dashboards, automations, integrations and complete platforms. From the first draft to the system running in production, built by a senior software engineer.
Multi-company messaging platform
A SaaS platform built from scratch for companies that send messages in volume. Each company has its own separate space, with campaigns, contact import from CSV, a real-time inbox with media, automated support flows and per-contact tracked links. Campaigns run in queues with pace control, and an AI reviews the text before sending to point out risks.
Technologies: NestJS, Next.js, PostgreSQL, Redis, BullMQ, Gemini, DigitalOcean, CI/CD with GitHub Actions
Observability for Node.js applications
An open-source library published on npm (@fabbahiense/pulsar-node and @fabbahiense/pulsar-pino-transport) that collects and organizes the logs of applications in production. Integrated with Quasar, it processes more than 1 million logs a day.
