The thesis
AI writes the code. Founders pay the engineers who knew WHY to write it. The daily WHY log is your proof · the only one AI can’t fake for you.
★ Evolution · why proof exists
AI is your ghostwriter, but you are the author. I was speaking with my friend Arya about the complex dynamics software teams face now that most code is being generated by AI agents. Arya put it succinctly: AI is your ghostwriter, but you are the author. It's your name on the cover of the book. I think the next year of software engineering will be building out the tools that enable all of us to be proud to sign our name to the increasingly complex systems we produce with our agents.

The pathology
You write clean code. AI writes it too now.
The cost
Your craft commoditized. Founders can’t tell you apart from the model.
The discovery
The engineers founders hire next have a record AI can’t fake — in their voice, on dated record.
The answer
Proof. One line a day in your voice. The line on your profile founders read before they hire.

Wednesday I got stuck because of some minor coding errors.1. I used "=" instead of "==" in the if condition.   "=" assigns a value, but "==" compares values.2. I wrote "digitalwrite()" instead of "digitalWrite()".   Arduino is case-sensitive, so the capital "W" is important.

I decided to start the backend and aws learning over just working on flutter because for wide range of knowledge and it'll be helpful for standalone projects

You don't need a physical location to build attention and trust in your customer, meet them where they are from Seth Godin's blog titled "In defense of popups"
Why
What I tried to apply this to but couldn't yet: cuz I'm not buildin my own business yet, but interesting takeaways nonetheless.

Another thing - critique & feedbacks for the my designs. When ever, I explaining the designs with the developer team, I will face a lot of good questions & points, I missed out. I learned this - Collaborating with founders & (engineer) folks - would open a door for more clarity on the process. Improves the quality of the outcome. Importantly, the burnout decreases. Expectations matched perfectly.

LEARNED
I learned why small annotations and micro-interactions are so important when presenting designs to stakeholders and founders. from What I’ve learned from my failures.
Why
What I tried to apply this to but couldn't yet: When presenting designs, without annotations and interactions, there’s a high chance the idea could be misunderstood or head in the wrong direction, making it unclear what problems we’re addressing with the solutions. This can lead others to guess and introduce bias. Since only you know how the designs work, mentioning their function upfront is crucial in design critiques and feedback sessions.

I selected the Hybrid Test Framework (POM) over the Modular Framework because it provides better scalability, reusability, and maintainability for automation testing projects. By using the Page Object Model (POM), web elements and test scripts are separated, making the framework easier to manage and update when application changes occur. The hybrid approach also combines the advantages of data-driven and modular testing concepts, improving test efficiency and reducing code duplication. This framework is highly suitable for large and complex applications where stability, readability, and faster test execution are important.

BUILT
Today I revamped the authentication system to make it production-ready. I moved JWTs into HttpOnly cookies for better security, added CSRF protection, built custom login/logout logic, also verified the full flow from registration to logout.
Engineer #106
DECIDED
I made a decision to work on the priority task of complementing the mid-fidelity wireframe first and planned to connect with manager during usability testing.

THINKING
I thinking about, today i planned to study but I didn't do that according to my plan because I get distracted by few things like using mobile and didn't focused on my studies and most importantly i didn't curious about that
