Numerous Oriabure

Full-Stack Software Engineer & Systems Architect

High-Concurrency Web Platforms • AI & Document Automation • Real-Time Systems

Open to Full-Time & Contracts (30+ hrs/wk) Benin City, Nigeria (GMT+1) Verified ID
Executive Summary

I build software that solves real business problems — full-stack web applications, multi-tenant SaaS platforms, self-hosted cloud infrastructure, and increasingly, AI-powered systems that deliver tangible utility rather than gimmickry.

My core engineering stack is centered on Python, Django, React, Docker, and Linux. I have extensive experience architecting decoupled systems: background worker queues (Celery/RabbitMQ/Redis), atomic relational database concurrency (PostgreSQL row-level locking, high-throughput SQLite WAL mode), reverse-proxy automation (Nginx), and browser graphics simulations (Three.js 3D physics and custom GLSL fragment shaders at 60 FPS).

I take products from concept through architecture, API design, database schemas, frontend interfaces, and production deployment on independent Linux VPS infrastructure. When solving complex challenges, my workflow follows a rigorous discipline: Understand → Plan → Build → Test → Refine → Deploy.
