In the tech world we are heavily adopting AI, we use it every day, we change the way we work. Not just the big tech, even small-mid sized companies are also evolving their engineering best practices.

I got assigned an oncall task. I didn't have much time to look into, then some internal AI agent decided to address the task and made all the code changes and sent it to me for review. The issue was resolved. I only spent a few minutes for reviewing AI code. Feels like living in the future.

If you are using AI regularly for your SWE job, this is a must read.

AI fatigue is real and nobody talks about it | Siddhant Khare
You're using AI to be more productive. So why are you more exhausted than ever? The paradox every engineer needs to confront.

I started to enjoy this whole "AI Orchestration" thing. I currently have 2 AI Agents running in parallel in different code bases and working on the tasks I assigned to them.
I also don't need to check the status regularly, it just notifies me when it's done.
Oh the future is exciting.

I've been using Claude Code (with Opus 4.5) for the past 2 days and I want to share some observations.
TL;DR
- 99% of the code I have is AI generated, code quality is amazing
- I saw some behavioural issues, but not a massive deal

I made some code changes with AI and asked it to create a diff, it referred the changes as "changes WE made", not claiming all the credit, well done :)

Not the exact same issue, but I placed an order online, with the estimated arrival date being 4th Feb, Gmail thinks it’s 2nd April 🤷♂️

Love What You Do
Instead of pursuing what you love you should pursue what you are good at as the success will compound which is what will really keep you engaged. This goes for hobbies as well as work and keeping them...

snapbyte.dev is finally live!
I’ve been working on snapbyte since August. I started building it after realising I cannot find time to read content aggregators anymore. It fetches top stories from aggregators, summarises them multiple languages and creates digest based on user configuration.

I read 5 blog posts today, all quite short, 2-3 minutes read each, but I found them all very useful and it made me realise I should go back to reading more.
I haven’t set any New Year’s resolutions for 2026, so this will be the first one in the list.
📚I want to read a book each month this year.

A couple of years ago I hanged my childhood on my office wall.
This Christmas I got a game boy color for myself as a present to relive my childhood.

One of the neighbours cat and pops in every now and then to make my day better.

I’ve been skeptical about what AI can do for me as a coding agent as it repeatedly failed very simple tasks I’ve been giving to it.
Finally yesterday I used Claude Opus 4.5 and it didn’t make any silly mistakes and successfully created 5 commits for me.
