Edi Wijaya

🎨 Hello! I’m Edi Wijaya, an AI Engineer based in Jakarta, Indonesia.

With over 6 years of hands-on experience, I specialize in building high-impact AI solutions that drive business value across Artificial Intelligence, Software Engineering, and Data Science.

🌈 About Me

I’m a Machine Learning Engineer who enjoys building smart systems that actually make a difference. I come from a modest background, so I’ve always valued learning deeply, thinking long-term, and using technology to create real impact—especially in finance and decision-making. For me, it’s not just about the models or the code, but about crafting solutions that are thoughtful, reliable, and genuinely useful.
