What I'm looking for

I’m looking for an engineering role where I can build IoT systems (ESP32/MQTT/Node-RED), strengthen networking troubleshooting, and apply meticulous data-quality work for AI. I want a team environment that rewards learning, accuracy, and reliable delivery.

I’m a Computer Engineering graduate with a strong focus on hardware–software integration, building microcontroller-based IoT projects and turning data into reliable results. I’ve developed solutions using the ESP32 with MQTT data communication, visualization with Node-RED, and cloud platforms, including real-time GPS tracking. I bring disciplined quality control—speech data recording, validation, and labeling—so AI training datasets are accurate, consistent, and ready for model use.

On the engineering side, I’ve built internal systems using PHP (Symfony) with MySQL databases and created RESTful APIs to connect application modules, including server configuration and deployment on AWS for stable performance. I also strengthen my technical foundation with networking and troubleshooting skills supported by Cisco CCNA (Introduction to Networks) and IT Essentials, and I’ve developed customer-facing execution through roles in retail operations and computer repair—helping me communicate clearly and deliver under targets.
