DevOps Engineer/Technical Lead

[Adewale Yusuf @AdewaleYusuf_]

One of the startups I invested in just raised $200M at a $5.2B valuation.

I backed @mercury while I was still in Nigeria; no proximity, no special access, just belief in the mission.
My investment? A small check through @Wefunder

The lesson is simple:
You don’t need to be rich.
You don’t need to live in the US.
You just need to start.

Platforms like Wefunder, Republic, AngelList, and StartEngine make it possible to invest from as little as $100.

Start small. Start early.
Because one decision today can compound into something massive tomorrow.

Hi Founders,

Don’t allow anyone sweet pitch to you on the TL in a bid for you to hire them o.

Don’t be moved by cold emails generated mostly by AI.

It’s until you hire them you discover they can’t deliver.

If you are hiring anyone, go through all processes of recruitment; experience review, previous work evidence, behavioral interviews, ask for references from previous places of work.

Never Again!

@ehoneahobed My Dr is back awesome....

I remember you were the first person to give me insights about the #ALX_SE program and I decided to register.

Today I don't only train people transitioning to tech, I also work as a full time backend software engineer.

Glad to have you back.
