One third of our lives, better read about it.
This thread will be updated as I read further & further.

In simpler words:

Started a week ago, not knowing how to write a single line of code
I wanted to read the Bhagavad Gita daily, but couldn't find an app that felt right. So I built one.
Ended with a full iOS app live @10minutegita on the App Store:
→ 239 daily readings of the Bhagavad Gita
→ Original Sanskrit shlokas + transliteration
→ Verse-by-verse translations & commentary
→ Personal daily reflections
→ Streak tracking with calendar heatmap
→ Shareable verse cards with 8 gradient themes
→ Hindi & English bilingual support
→ Light/dark mode, adjustable fonts
→ Completely offline after download
Total cost: $200 Claude Max Subscription + $20 ChatGPT Pro Subscription + $99 Apple Developer fee
Lines of code I wrote: 0
Claude Code wrote everything. I just described what I wanted in plain English (non-technical background). Codex reviewed it. Now it's live on the App Store.
The barrier to building isn't coding anymore. It's just knowing what problem you want solved.
If this is of value to you, I'd appreciate it if you downloaded the app & let me know your feedback. Process attached below
DM me if you want help building something similar.
What Claude Code actually did:
• Created 50+ files with React Native, Expo Router, TypeScript
• Set up file-based routing, state management, and AsyncStorage
• Wrote & validated 239 snippets in English and Hindi
• Ran 20+ parallel agents to fix Hindi data quality issues
• Built a share card generator from scratch
• Fixed bugs when I just pasted screenshots
• Set up GitHub Actions CI/CD
• Prepared App Store metadata and submission

Two retail stores in New York City may appear to be direct competitors, but this is an illusion.
Each store has a supply chain stretching from its shelves out to the world
Before a customer walks into the store, often the game is over based on the superior supply chain.

A Thread 🧵👇
1/ History.
IRFC was established in 1986 as a dedicated market borrowing arm of the Indian Railways, registered with the RBI as an NBFC (Systematically Important)
But why do Railways need them, can't they directly ask for funds from the Ministry of Railways (MoR)?
2/ Here, enters the Government according to whom raising money from the open market is not the duty of MoR, it is the duty of the Ministry of Finance (MoF)
which didn't want to act as an intermediary & thus IRFC was born to raise money& fund the capital needs of Indian Railways.
Real estate stocks have taken a tiny hit due to the interest rate hikes
Zoom Out. This is just a minor blip in this cycle
If the cycle goes the way it has in the past, most of the companies can become 5-10x larger in the next 5 years
If it doesn't, you still double your money.
1/ From Godrej Properties Q2FY23 concall
Price acceleration (across all markets) is driven by the end consumer & not just investors. Interesting.
2/ Continuing on the above... Mr. Godrej is quite bullish on the real estate cycle picking up in the next 4-5 years. That's why they are doing a lot of asset-heavy deals these days & did massive QIPs.
Later, we might see a downcycle again. Still, good times are probably near.
Strong execution from Sunteck Realty: Targeting a 1800crs TTM Pre-sales by FY23 end.
- $ 3.8 billion (30K crores+) is Est. Gross Development Value (GDV) of the upcoming project pipeline in the next 7-8 years
- 37 million sq ft Across 7 projects
Very Interesting!
1/ They have nearly 2000 crores unsold inventory as of the date
They are also planning to launch 6000 crores worth of projects in the next 18 months
If the demand scenario stays robust, the targets above should not be hard to meet
Target: Double Pre-sales every 2-2.5 years 🚀
2/ "Sunteck has grown in the last 15 years with all the headwinds in the industry. We have been able to grow at a time when most other players have not been able to survive." ~ Kamal Khetan, Chairman & MD.
