What I'm looking for

I’m looking for a role where I can build full-stack, event-driven systems with AI and distributed backends—using modern React and Node, containerized microservices, and strong engineering practices like validation, security headers, and reliable deployments.

I’m a Full-Stack Software Engineer who builds scalable web applications, AI-powered systems, and distributed backend services. I enjoy designing event-driven architectures, optimizing relational and time-series data, and deploying containerized microservices that stay reliable under real production workloads.

In my recent role at Deus Media Group (Remote), I developed features for a production SaaS platform, strengthening system reliability and performance. I built responsive frontends with React, Zustand, and TanStack Query, engineered real-time communication with Socket.IO, and implemented RESTful APIs using Node.js/Express. I also integrated local AI models via Ollama to automate content generation workflows.

On my projects, I’ve focused on end-to-end system design—from low-latency security and IoT integration to scalable booking platforms. I’ve built dual-database architectures (PostgreSQL + InfluxDB), event-driven pipelines (MQTT/WebSockets, Kafka, Redis atomic counters), and automated flows with tools like Node-RED and Docker Compose, while delivering robust authentication, validation (Zod), and production-ready deployment with Nginx and security headers.
