About Me

I'm a passionate Software Engineer who loves building platforms that truly stand out and deliver great user experiences. My main focus is backend development, where I've worked with TypeScript, GoLang, and Java to design, scale, and orchestrate modern microservices and AI agents. On the frontend, I enjoy crafting clean, engaging interfaces with React. I'm driven by the new era of intelligent systems, exploring how autonomous agents and AI can enhance products and make them smarter.

Above all, I'm driven to push platform quality and performance to the next level while creating meaningful, forward-thinking solutions.

From my roots as an aeronautical engineer, my journey has been a transformative one, molding me into a versatile Software Engineer. Along the way, I had the chance to dive into the role of a Teaching Assistant, mentoring emerging talents and guiding them into the development world. My focus on effective leadership and ability to adapt to various cultures have consistently led to successful outcomes across a wide range of domains.

Let's connect to explore new horizons and drive transformative tech solutions.
