Hello, I'm Julia.
✍🏼 Blog posts on my experience as a software engineer
I'm trying to solidify my learnings and help others at the same time by writing these short blog posts. I generally write about problems I come across and how I solved them. I'll occassionally also write about my personal experiences of navigating my career as a software engineer. If you spot an error, or have any comments, suggestions or questions about what I've written, contact me on Twitter @bionicjulia, Instagram, or email hello at bionicjulia.com. I'd love to hear from you. 🤓
P.S. I'm thinking of starting a newsletter where I'll send through my latest articles, books read and other interesting things I come across. Interested? Sign up here. If I get more than 10 subscribers, I'll kick it off! 🙃
