Über Zebedee Ejike
Hi, I'm Zebedee. I am a backend engineer and systems architect based in Duisburg, Germany.
I specialize in keeping software systems secure, performant, and bug-free. I don't just write code; I build automated workflows and deep-dive into architectures to solve complex problems quickly and reliably.
What I do best:
•Urgent Bug Fixing & Debugging:Drop me into a legacy or modern codebase, and I will isolate the root cause, implement a fix, and write automated tests to ensure it never breaks again.
•Security & Performance Audits:I conduct deep-dive architectural reviews to identify vulnerabilities, memory leaks, and bottlenecks, delivering actionable reports alongside the fixed code.
•Backend & API Architecture:Building robust, scalable APIs and server infrastructure using Node.js, TypeScript, and Python.
My Approach:
I utilize advanced, custom-built code-analysis tooling and automated pipelines. This allows me to navigate and audit large codebases significantly faster than traditional manual reviews, ensuring you get production-ready results with rapid turnaround times.
Communication is key. I provide clear, concise updates without technical fluff so you always know exactly what is happening with your infrastructure.
If you have a critical crash, need a security review, or want to scale your backend, send me a message. Let's get it fixed.
