5 things I wish someone told me before I started my first startup

Crazy how much your life can change in a year 😭

One of our enterprise contracts wanted WhatsApp connections for their agents built out. We were told it should take 3-4 weeks to do. I locked in and shipped it in 6 hours…

Why you can’t get a software engineering job in 2026 and how to fix it

[Erik Cupsa @swerikcodes]

Every once in a while you just have to lock in and get shit done. Rebuilt the entire Meuze landing page in 30 hours, barely slept.

99% of vibecoded apps don’t have all 5 of these built in, which causes majority security problems…

@vnyth Shoot me a dm I’ll interview u

[Erik Cupsa @swerikcodes]

Attention is the new currency.

[Erik Cupsa @swerikcodes]

Most important: do not apply with a weak generic resume.

Your resume gets you the interview before your coding skills are even tested.

Use ResuMax to review, score, fix, and tailor your resume to each job:

Software engineering in 2026 explained in 60 seconds…

I broke into big tech by doing everything in this roadmap and more for 223 days (all while documenting it).

Since then I got the return offer at Amazon, then turned it down to build my own VC backed startup. So safe to say it works.

Here’s everything I would if I had to restart so you can copy me.

@marouane53 Someone recently put that up to take my traffic haha, I’m resumax ai only

[Erik Cupsa @swerikcodes]

I built Resumax AI as a student. My first ever SaaS app, 16,500 users. $12,000 in revenue. In just 23 days of work, all documented on YouTube.

Building in public took me further than I ever expected. Far enough that I'm now going all in on a startup with an F1 driver.

If you're sitting on an idea, just build it. You have no idea where it could take you.

Listed Resumax on TrustMRR for now to see if someone wants to take it further (@marclou you cooked with this).

@deveshlogs For sure
