Hey everyone

I’m currently in the final year of my Master’s degree in Cybersecurity, and I want to seriously move into the fintech space after graduation.

As part of my learning journey, I built a Payment Gateway project from scratch to better understand how real-world fintech systems work (payments, security, APIs, services, etc.).

📄 Docs: https://docs-paymentgateway.redahaloubi.com/

The goal of this project was not “just another CRUD app”, but to:

• Learn how payment systems are designed
• Think about security, tokenization, transactions, APIs, and microservices
• Understand what actually matters in fintech products beyond theory

What I’d love feedback on

• Is this a good project for someone starting a fintech career?
• What features or concepts should I add next (fraud detection, compliance, ledgering, reconciliation, PCI ideas, etc.)?
• What should I focus on studying more if I want to work in fintech (tech + security)?
• Are there any bad assumptions in my design that I should fix early?

Also…

If you know:

• Startups that take interns or junior fintech engineers
• Open-source fintech / payment / security projects I could contribute to
• Or if you’re a founder / engineer and open to mentoring or chatting

I’d love to connect. I’m very motivated to learn, improve, and get real-world experience.

Any feedback — technical or career-related — would honestly mean a lot 🙏
Thanks for reading!
