Serialization sounds complicated.

It’s basically:

📦 Object → pack it → JSON → send/store it → unpack it → Object

"JSON.stringify()" = serialize
"JSON.parse()" = deserialize

Once you understand this mental model, APIs & backend communication make much more sense.

[Neeraj @_19_neeraj]

Most backend bugs don’t start in the database.

They start with a request going to the wrong place. 🛣️
That’s why understanding routing matters.

I made a one-page visual cheat sheet covering all those topics.

You probably use Express routing every day.

But could you build it without Express?

Most developers know the syntax.
Far fewer understand what’s happening underneath.

These 2 pages break down Node.js HTTP routing from the ground up.

Most developers use HTTP daily—but do they understand what happens underneath?

This visual guide breaks down a basic Node.js HTTP server:
• request → response flow
• req vs res
• createServer()
• status, headers & body
• res.end()
• listen()

Solving DSA every day. Logging everything.
Felt productive.

Then I'd see the same problem weeks later
and blank completely.

The solving wasn't the problem.
The forgetting was.

So I built something that fixes it 🧵

The moment your solution is accepted:

→ Popup appears pre-filled with problem details
→ You rate how it felt in 20 seconds
→ SM-2 algorithm schedules your next review

Struggled on DP? Back tomorrow.
Breezed through Binary Search? See you in 3 weeks.

Memoize — a Chrome extension that auto-captures every
accepted LeetCode and Codeforces submission and schedules
exactly when you should review it before you forget it.

No spreadsheets. No manual logging. Ever again.

Tired of tracking leetcode in spreadsheets. built a chrome extension that auto-captures every accepted submission — problem, difficulty, tags, many more...

then built a dashboard to actually analyze it.

Building — feedback on features/UI?
