Luis Henrique Jung -- Fullstack & AI Engineer

01 My Story

The Beginning

From Curiosity to Code

Started in software development driven by a deep curiosity about how systems work. From writing my first lines of code to understanding the full stack -- every challenge became a stepping stone. I pursued a BSc in Analysis and Systems Development at UNIVATES, building a solid foundation in software engineering.

Mobile & Cross-Platform

Going Beyond the Screen

Dove into mobile development with Android (Java) and Flutter, building cross-platform applications that run anywhere. Created Smart Keeping -- a modular Flutter app with clean architecture and reactive state management. Earned a Postgraduate degree in Software Engineering for Mobile Devices.

Fullstack Engineering

Architecting at Scale

Joined RSData as a Full Stack Engineer, designing REST APIs, optimizing databases, and implementing CI/CD pipelines. Built production systems with Spring Boot, Angular, NestJS, and Python -- contributing to architecture decisions that shape how teams build software.

The AI Chapter

Where Code Meets Intelligence

Transitioned into applied AI, building autonomous agents and LLM-powered features integrated into real applications. Using LangChain, LangGraph, and MCP to create systems that think, reason, and act. Computer vision experiments for workplace safety. This is where I'm heading -- making AI solve real problems.

Biometric PPE Delivery Platform

Workplace Safety · Production System · 1,000+ Users

Built a fullstack biometric verification system for fast PPE (Personal Protective Equipment) delivery in companies with hundreds of workers. The system currently has 15,000+ enrolled faces. Workers confirm PPE delivery via face recognition or fingerprint, get matched to their equipment profile, and receive the right gear in seconds -- no manual ID checks, no paper logs. Includes a face-based employee search: point the camera at a worker and the system instantly identifies them and pulls up their full profile.

AI-Powered Risk Management

Workplace Safety · AI Agent · Flutter App

Developed a mobile application that lets safety professionals quickly identify and manage workplace risks. Integrated an AI agent (Gemini Flash Pro orchestrated with LangChain, monitored via LangSmith) that recommends risks based on activity descriptions and workplace images -- accessible through a conversational chat UI with contextual action buttons that simplify complex workflows into one-tap actions.
