Iโm transitioning into backend engineering.
I work with real-world systems (warehouse automation), but Iโm leveling up in:
โข Python (FastAPI)
โข SQL
โข AWS
โข System Design
Building projects + documenting everything I learn.
600 followers in 30 days. ๐
No growth hacks.
No buying followers.
No going viral.
Just building in public.
I shared what I was learning, what I was building, what broke, and what I fixed.
The biggest lesson?
People donโt follow perfection.
They follow progress.
If youโre a builder or founder, start posting. Your next opportunity is probably one post away.
Road to 1,000. ๐ฅ
๐ AI helped me build a chatbot in 30 minutes.
Then one prompt broke the entire app.
Fixing it took over a day of debugging, tracing dependencies, and inspecting code.
๐ค AI generates code.
๐ง Engineers understand systems.
AI makes developers faster, but knowing how to fix what breaks is still the real superpower.
The interview process is undefeated.

That was a very short next step.
Interesting how the solution wasnโt more models or more complexity.
Just better context and the right tools.
A good reminder that architecture often beats brute force.
How OpenAI Built Its Data Agent
Most teams building data agents stack routers, fine-tunes, and complex retrieval pipelines on top of multiple LLMs. OpenAI didn't.
Their data agent runs on a single model and only 13 tools, across 1.5 exabytes and 90,000 tables. It's "pretty vanilla" by design.
We spoke with Emma Tang, Head of Data Platform Engineering at OpenAI, to better understand the architecture and the engineering decisions behind it.
The article covers:
- The architecture behind the data agent
- The six layers of context that make a single LLM reliable across 90,000 tables
- How OpenAI Uses Codex Internally: 3 Use Cases
- Five practical lessons for any team building a domain agent
- Where OpenAI's data platform is headed next
Quick roll call ๐
Who here is building something in 2026?
Could be:
โข An AI agent
โข A SaaS
โข A mobile app
โข An automation
โข A side project
Iโm always looking to connect with builders and learn from what others are creating.

Quick question for builders:
Has anyone here built a WhatsApp AI agent using the WhatsApp Cloud API?
Iโm trying to get real inbound messages working through webhooks and would love to hear about your setup, lessons learned, or any gotchas you ran into.
What stack did you use?
