Actually I had this same doubt. My situation is similar to yours. I like IBC quite a bit, but my knowledge is surface level. I know how things roll in IBC but I lack in-depth knowledge of the subject, neither do I believe I can develop it within 5-6 months (given that I also have to read subjects for my semester exams and a hell lot of other engagements). I am in a position to write blogs and articles which will explain a particular provision (say Sec. 29A) in a stagnant form. Furthermore, I've been following blogs and quality articles around the same and my observation is that the reputed blogs and articles doesn't simply explain the sections/provisions but analyze contemporary developments around the same, I really feel underconfident to write a piece around recent delegated legislations within IBC which is kind of untouched and there is a dearth of material explaining the same. What shall be my approach to tackle this issue?
(I cannot sit idle and wait till I gain a substantial knowledge of the subject to write up stuff, where people around me are acing at it, I've got a CV to take care of).
Anything insightful to this conundrum of mine will be much appreciated : D

One of our Constitutional Law teachers at NALSAR had created these videos for us in November 2020.
They were helpfully framed as an 'Introduction to Academic Legal Writing' in 3 parts. Hope this gets you started.

Part 3:

Here are my two cents.
1. Instead of looking for a topic, just start reading. The more you read, the more number of perspectives you learn. The more perspectives you learn, you start forming your own based on the rationale behind each opinion. The more you read you also understand how to analyse a problem critically and how to articulate your opinion on it.
My approach to writing is problem solving. I spot a problem and through my writing I try to find solution to that problem.

2. Don't confine yourself to one subject or even just legal reading. Read economics, history, perhaps something relating to management. Variety of reading allows you to domain hop. In essence, sometimes you find a solution in one domain which you can apply to the domain that you want to write on.

I hope this helps.
