Today marks the birthday of my newsletter 🥳! It turns out that I wrote quite a bit during the year, so I decided to compile all the posts and release them as a book (260 pages). The book is available on Leanpub: DRM-free EPUB/PDF. Get the book: leanpub.com/thecodercafe... RT appreciated 🙏.
I re-enabled my Calendly session: calendly.com/teiva-harsan... If you want to chat about tech, non-tech topics, whatever, feel free to book a slot!
