Hi, I'm —
Jimmy
Backend, FinTech, Applied AI and more
I'm a software engineer aspiring to build complex, reliable software — spanning trading terminals, multiplayer games, and full-stack applications. I ship quickly with agentic workflows while staying grounded in the fundamentals and the underlying technologies. Currently sharpening my craft by building projects.
