About Author
This author has 20+ years of experience in software engineering and cloud engineering. In an industry where knowledge becomes obsolete in the next three months, he learns anything that crosses his path indiscriminately. He floats from one technology to another like a moth and stings the problem sets like a mosquito. This author codes Java while drinking Espresso and writes Spock specifications while listening to Groovy beats. He masters Google Cloud Platform just like how he masters the art of predicting the movement of dark clouds over his backyard, where 60% of the time, he is right every time.
This author suffers from the Dunning-Kruger effect, where he overestimates his competence and underestimates his ignorance. Technology buzzwords never faze him, for he does not know enough to be afraid of in the first place. GCP, GCS, GCR, GKE, GWT… everything sounds the same to him. He never fears acronyms, synonyms, or antonyms, for he has ChatGPT in his back pocket. This author is a jack of all trades but a master of none. He writes like he knows all the answers, yet he googles for better solutions from elsewhere. He fakes it until he makes it; if he doesn’t, that’s okay because he has the attention span of a squirrel. The blog posts are his buried walnuts, in case he needs them one day.
In conclusion, this author is full of something. He apologizes in advance if you are trying to solve your company’s real problems with his shitty solutions. There, he has successfully written paragraphs of nonsense because every professional blogging website needs a section about the author, with a too-cool-to-smile portrait staring sideways into the abyss.
