Hello World, I am
Lucas Simonini.
I architect scalable backend solutions.
I'm a Senior Software Engineer with over 15 years of experience designing, developing, and maintaining robust systems. From open banking to global retail platforms, I leverage Java, cloud technologies, and microservices to solve complex business challenges.
01. About Me
I am a highly skilled and accomplished Senior Java Engineer with a passion for technology, programming, robotics, and electronics. Over the past 15 years, I have successfully delivered complex projects across various industries including travel, retail, and fintech.
As a self-learner, I am always open to acquiring new technologies that serve the best interests of the projects I undertake. My core philosophy is that good architecture paired with clean, maintainable code drives business innovation and stability.
Currently based in Spain, I'm fluent in English and Portuguese, with intermediate Spanish, making me an effective communicator in diverse, agile, and distributed international teams.
