Finally Completed making my Portfolio Website.
Always wanted to create one and today is the day.
Here's the link :- https://t.co/flwHqrsiZB
Constructive feedback is always appreciated..!!
100xdev community is motivating me to explore and build new things.
@kirat_tw Thanks sir..!!

I joined as a software engineer, but lately I've been spending so much time with data that it feels like I'm slowly becoming a data engineer.

Building data pipelines, ETL, data studio, big query been spending a lot of time learning about this concepts.

Company needs!!

[Abhishek Singh @0xlelouch_]

CTO: We lost our strongest backend engineer today.

Founder: The one handling infra and outages?

CTO: Yes.

Founder: Did a bigger company hire him?

CTO: No.

Founder: Then why quit?

CTO: He said he was exhausted.

Founder: From the workload?

CTO: Not exactly. From watching the same database bottleneck, same queue lag, same deployment mistakes come back every month.

Founder: That happens in fast moving teams.

CTO: He agreed. What he could not accept was that every fix was temporary because nobody wanted to slow down and clean the system properly.

Founder: We had deadlines.

CTO: He had standards.

Founder: So he left because the work was hard?

CTO: No. He left because he was not doing engineering anymore. He was just containing damage.

The best engineers do not hate hard problems.

They hate preventable problems that management keeps normalizing.

Just updated my portfolio..!!

• Built an MVP from ideation with a founder
• Helped scale an OTT platform to 1.5M+ users
Currently building & exploring AI + Solana/Web3.
If you're building something interesting let’s connect.

Learning how Compute Units (CU) work on @solana
- CU is measured at runtime
- Default limit ≈ 200k
- Exceed limit -> tx fails
- Cross-program calls are expensive
- CU = validator CPU usage
- Higher CU + priority fee = faster tx

#Solana #Web3 #Blockchain #developer

[Rahul Soni @SoniRahul3108]

Ever wondered how fees work on Solana?

- Base fee ≈ 5000 lamports (mandatory)
- Compute Units = how much “work” your tx needs
- Priority Fee = pay per CU for faster processing

More CU + higher price = higher priority

Fungible Tokens vs Non-Fungible Tokens

1. FTs
- Same value
- Interchangeable
- Divisible
- Used in DeFi

2. NFTs
- Unique
- Non-interchangeable
- Proof of ownership

FTs = Digital money
NFTs = Digital assets

[Rahul Soni @SoniRahul3108]

Program Account → Stores smart contract code
Data Account → Stores tokens, NFTs, and app data
System Account → Holds SOL and pays fees

[Rahul Soni @SoniRahul3108]

No database. No servers.

So where does Web3 store data?

Learned this while studying Solana :-
- Program -> Code
- Data -> Storage
- System -> SOL
Flow: Pay -> Execute -> Store

#Solana #Web3 #Blockchain #BuildInPublic

[Rahul Soni @SoniRahul3108]

Just learned about Lamports in Solana.
Think of it like this:
1 Dollar = 100 Cents
1 Rupee = 100 Paise
1 SOL = 1,000,000,000 Lamports
Lamports are the smallest unit of SOL.
So if you send 0.5 SOL ➝ You’re actually sending 500,000,000 lamports.

Building a browser based web3 wallet and hit this error:

ReferenceError: process is not defined

Turns out ed25519 lib depends on Node.js internals like process, which don’t exist in the browser.

Fix: Replace it with micro-ed25519-hdkey a browser-friendly alternative.

@sama @grok explain this

@BandaTharun7 Hey tharun lets connect and learn together...!!

[Rahul Soni @SoniRahul3108]

Let'ss gooo...!!!!!
New year, new learning..... 💫

[Rahul Soni @SoniRahul3108]

High-level DB schema locked.
Workflow finally has a solid backbone.
Next up :-
- Set up Prisma
- Design the database
- Start wiring backend endpoints

[Rahul Soni @SoniRahul3108]

Today’s learning sprint

- Integrated PhonePe Payment Gateway.
- Deep-dived into Redis caching.
• Cache-aside pattern
• Race conditions (finally makes sense)
• Short TTLs & versioning to fix them

Backend engineering hits different when things click.

First coding session on my new table💻💫

[Vaibhav Agarwal @va_a14]

Comfort is Cancer.

The most dangerous salary in the world is ₹5 LPA. It is enough to survive. It is enough to pay rent. So you stop running. You stop learning. You settle.

Meanwhile, the guy at ₹40 LPA is still grinding because he knows the market is ruthless.

Is he 8x smarter than you? No. He just didn't let "bad luck" become his identity.

Luck might decide where you start. But grind decides where you finish. Become so good that the market cannot ignore you.

Make your success inevitable.

[Rahul Soni @SoniRahul3108]

Do you know the difference between these two?

Promise.race() → returns the first promise that settles (resolve or reject).

Promise.allSettled() → waits for all promises, success and failure both.

I was confused by this too at first.
