I build production web and mobile apps for founders.

The latest is drivea, an app for UK driving instructors. It runs on iOS, Android, desktop and web, works offline and takes card payments.

I built all of it, frontend and backend.

Open to monthly contracts. DMs open.

It had to work offline. Instructors teach in car parks and on country lanes with no bars.

Lessons, notes, messages and payments save on the device first, then sync when signal comes back.

Stack: Tauri for the apps, Node.js on the server.

Your startup just hit 10 million users. Queries are slow. The DB is choking.

Your Tech Lead says: "We need to shard the database."

What's your first question back?

What ByteByteGo actually trains:

How to think through a system out loud.

Free stuff first:

→ YouTube — deep system design walkthroughs
→ Weekly newsletter — how Netflix, Uber, WhatsApp built their systems
→ Blog — real architectural tradeoffs explained

Start here. Then decide on the paid content.

Topics ByteByteGo covers that interviewers actually ask:
→ Consistent hashing
→ Rate limiting
→ Distributed caching
→ Database sharding + replication
→ Message queues
→ Notification systems
→ URL shorteners
→ CDN design

All with diagrams. Not wall-of-text theory.

@SANDY4AYU Hi

Unpopular opinion: Redis is one of the most overused tools in backend development.

You've added it to a project you didn't need it for. Admit it.

What's the most unnecessary place you've ever used Redis? 👇

Boolean search takes 10 minutes to learn and saves 10 hours of job hunting every week.

Save this thread. Share it with someone who's been applying for months and getting no response.

They need this more than you know.

You're searching for jobs on LinkedIn the wrong way. Stop typing job titles into the search bar like it's Google. Start using Boolean search. Here's everything you need to know. 🧵

GCC companies like Walmart Global Tech, Barclays, and Citi don't always post on regular job boards.

Try this in LinkedIn People search:
"Talent Acquisition" AND "Walmart Global Tech" AND "Bangalore" DM them directly.

No ATS. No black hole. No middleman.
