About Me

Originally trained in finance, I became deeply curious about how financial systems and software actually work together. That curiosity led me to teach myself programming and start building my own tools related to financial workflows and data. Today I work as a full-stack engineer, combining finance knowledge with software to build practical systems.I'm always excited to learn new technologies and share knowledge with the community.

Outside of the IDE:

  • 🤸 Calisthenics & Gym: Chasing the next PR or static hold.
  • 🐕 Dog Dad: Keeping up with my two pups.
  • Continuous Learner: Always exploring new stacks and learn to be better
