👋 Hi, I'm Mayowa Kalejaiye

Profile Views


🚀 Who Am I?

Alright, let’s keep it real. I’m Mayowa — a backend-focused full-stack developer who enjoys making things work behind the scenes. APIs? I build them. Databases? I optimize them. Strange bugs at 2 AM? I debug them (not proud, but it works). My stack? Python, Django, PostgreSQL on the backend. React on the frontend. I care about clean code, readable systems, and building things that last.

Recently, I’ve been exploring how AI (LLMs, prompt engineering) fits into backend systems — from reflection engines to content personalization. It’s not just about writing code. It’s about thinking in systems, collaborating with people, and shipping solutions that make sense.

Let’s build something thoughtful.

🎤 A Saying That Defines Me

"I don’t just solve problems—I make them regret existing in the first place." – My Personal Dev Philosophy


😆 Fun Fact

I once deployed a project on a free-tier service, only for the database to ghost me when it hit the limit. I felt like a startup founder getting rugged. Lesson learned: Always read the fine print before trusting "free." 😭
