Bridging the Gap Between Theory and Practice
A software engineer at Flexidao and university lecturer at La Salle URL.
- Experienced in full-stack software development and research
- Mentored 300+ students
- I led the development of MLA
Experienced full stack SWE with a passion for building high-performance and scalable software applications. Proven ability to work across all layers of the stack, from front-end development to back-end infrastructure.
Beyond my day-to-day work - Featured Projects
Moodle Learning Analytics
MLA is an application for professors & teachers that analyses students' generated Moodle logs and performs sentiment & emotion analysis on forums' discussions. Starting from January 2022 the software will be used in different Spanish Universities and schools (La Salle URL, UPC, URV, Euskadi schools, etc)
Yako - Heterogeneous Computing Farm
Engineered an orchestrator that determines the viability and handles the deployment of computing services into a multi-layered distributed heterogeneous environment with support for traditional and IoT computing nodes via gRPC and MQTT protocols. The project serves as the foundation of multiple IoT research project at La Salle.

Kind words from peers & students
I first met Jiahui at Build@Mercari and had the privilege of working together with him and other fellow members on a project shortly after the program. Jiahui proved to be an integral member of the team, bringing leadership and structure to the project. He quickly became the group’s go to member for questions due to his technical prowess and ability to clearly explain his ideas. It is clear he loves what he does and strives to be better every day. Throughout the project, he has consistently sought to learn new technologies and has always encouraged and inspired the team to learn and improve along with him. He is truly a very talented software engineer, a great teammate and friend, and an absolute pleasure to work with.

I consider Jiahui a great professional, and I have no doubt that Jiahui will succeed in any new direction his career takes.
Antonio Milán OteroDevelopment lead @ GRUP MEDIAPRO (AutomaticTV)
It has been a pleasure to work with Jiahui. He is one of the most professional individuals I have ever encountered. Jiahui is destined for a bright and successful future in his future endeavours.

Very good teacher, I really like how he explains. Whenever we've had doubts, he's been happy to answer us, and even if we ask him again for the same question, he's been happy to solve it for us. Especially for the practice part, as we had quite a bit of trouble to fully understand the 2nd phase of the file systems project.
