Muhammad Mustafa's Work | ContraWork by Muhammad MustafaMuhammad Mustafa
Full-Stack Developer Angular, React, Node.js SaaS & Shopify
Every client has said this at least once:
"It’s just one small change."
Then auth breaks, database need a migration, one integration stops working, and somehow it’s 2 AM 😅
Writing the change is usually easy. Finding everything it can break is the real work.
What was your biggest “small change”? Built an AI job hunter solo because applying to jobs by hand was eating my evenings.
It finds live vacancies, matches each one against my experience, and writes a CV tailored to that specific job. No more sending the same CV to 40 places.
I build AI features into web apps and SaaS products as a full-stack dev. If you're thinking about adding something like this to your product, my DMs are open. Speed gets attention. Reliability earns trust. 🏎️💨
Inspired by the Tesla Roadster, I explored what software performance really means when APIs fail, real data loads, or a payment is submitted twice.
