Auth isn't just a black box anymore! April 18 session on JWT and OIDC was a game-changer. Seeing the complete journey from the initial login to secure token verification made everything click!

Completed Day 1 of the ChaiCode Masterji Challenge. I explored the comprehensive Javascript Backend Roadmap which covers production-grade server architecture, professional directory structures, and database modeling. Ready to dive deep into the logic. @HiteshDotCom @ChaiCodeHQ.

Deep dive into SQL in April 5 Saturday class! From SQL vs NoSQL to mastering aggregation functions & filtering. Learned the nuances of ASCII, datatypes, and table management. Backend is coming together! @Hiteshdotcom @ChaiCodeHQ @nirudhuuu #database

[Sagar Sinha @saggysimba]

@ChaiCodeHQ @Hiteshdotcom @wjshubham Excited for the same!

[Sagar Sinha @saggysimba]

Got to revise so much about Typescript Fundamentals conducted by @yntpdotme in April 2 2026 T-class. Excited for what's ahead!

Refining fundamentals!
Auth revision with @piyushgarg_dev–step-by-step logic is a game changer. Plus, diving into @DrizzleORM & PostgreSQL for type-safe DBs.

Thanks @Hiteshdotcom @ChaiCodeHQ @nirudhuuu @yntpdotme

Well I am done with SQL for now. Wanted to post more, but will be back with something more creative!

[Sagar Sinha @saggysimba]

A LEFT JOIN (also known as a LEFT OUTER JOIN) is a method used in SQL to combine rows from two tables based on a related column. Unlike a standard join that only shows "perfect matches," a Left Join prioritizes the information in your primary table. #SQL #Data #InterviewPrep

[Sagar Sinha @saggysimba]

Deep dive into #NodeJS architecture! Understanding the Event Loop & Libuv is key to understanding how JS works in the backend!. Check out my latest post on the basics:

Today's learning is about CTEs and GROUPING: Data Binning with CTEs layers logic to turn raw metrics into structured categories.

A self-join pairs a table with a "virtual twin" to find internal relationships.✅Pros: Perfect for hierarchies (Org charts) & comparing row-to-row data without external tables.❌ Cons: O(n^2) complexity. It can be a performance killer on large datasets.#SQL #InterviewPrep
