Translation to English: Here is a translation of the Japanese text to English:

"I've had cases blow up on me before, so I haven't been able to put together my portfolio."

(Note: The parentheses contain an idiomatic expression that is difficult to translate literally. A more natural-sounding translation would be something like "because of past trouble" or "due to previous issues", but I've kept the original wording to preserve the nuance.)
