New write-up: Cloud & Modern Backend Architecture

This covers: traditional servers, serverless functions, edge computing, and Realtime services, how they work under the hood, their trade-offs and how they compose into a single hybrid architecture.

Published my first write-up: Hashing & Cryptography

It explains cryptographic hash functions from first principles—determinism, the avalanche effect, resistance pillars, and why these properties matter in real systems.

Built Hookfire — a production-inspired webhook delivery engine.

It displays async processing, BullMQ, Redis, PostgreSQL, retries, dead-letter queues, HMAC verification, idempotency, Docker, and AWS deployment.

Hear me out…

Two years back I joined X because I was tired….

Tired of jobs being posted on LinkedIn and within 1 hour of that, 100s of people had already applied. Everyone on LinkedIn was fake, trying to show how they were well-rounded and highly skilled. I barely made any REAL connections there.

Tired of tech influencers on Instagram saying, “COMMENT HI AND I WILL SEND YOU THIS IN YOUR DM,” just to increase their reach. I kept following them, commenting on their reels, getting the material in my DMs, and never really looking at it.

Then there was the cold email era where you send out 1000s of cold emails to recruiters, startup founders, and people in tech to either get a job or get some assistance for your startup. But let’s be honest, out of those 1000 emails, only 10–15 people (max) would reply.

But then there was X, where everyone is just being themselves. Even the most skilled people in your domain feel reachable here. Yes, there are a lot of shitposters, but there are also people who are really, really working hard and building something.

Hence, @shrav_10 and I are creating an X Chat for everyone interested in STARTUPS or TECH, where there will be only REAL tech talk.

We all can post important resources, job openings, and literally even collaborate and discuss startup ideas.

If you’re willing to actually GROW and NETWORK with the right kind of people here on X, then comment/quote/repost anything on this post and I’ll add you to the group chat.

Like I said, the right guidance and network can change your life forever!
