Hi, I'm Olusegun Ibraheem
I architect systems that scale — and ship them to production.
Senior Full-Stack Engineer with 9+ years delivering microservices, event-driven architecture, and cloud-native platforms in fintech and global workforce software. From system design to Grafana dashboards, I own the full delivery lifecycle.
About
Turning complex, ambiguous problems into production-grade distributed systems.
I'm a Senior Full-Stack Engineer with 9+ years architecting and shipping production systems for fintech and global workforce platforms. My background spans event-driven microservices in Node.js, NestJS, and Laravel; React and Next.js on the front end; and the AWS / Docker / CI-CD layer that gets everything reliably into production. I care deeply about system design, TDD, observability, and raising the engineering bar on every team I join.

Recent projects
A selection of some of my recent works
xurl.fyi — URL Shortener
High-performance URL shortener built on a Go API backend and Next.js frontend.
InnerMost
A mind-reading game — gamified from a childhood prediction trick I invented. Players put on a mental performance: correctly guess a number or word someone is secretly thinking of, compete on leaderboards, and challenge friends in real time.
DocMind
A RAG-powered document intelligence platform — upload any document, query it in natural language, and let stateful AI agents handle multi-step reasoning workflows.
Veci CRM
A production multi-tenant CRM built from scratch for Veci Technologies — Django 5, domain-driven monolith across 20+ bounded contexts, Celery workers, WebSocket support via Daphne, live in production.
WriterIX
Multi-tenant AI content SaaS — workspaces bring their own LLM keys, pick a provider, and run end-to-end blog pipelines with live review gates, RAG knowledge bases, and social publishing.
Let's build something.
I'm always open to new projects, senior engineering roles, or a conversation about hard distributed-systems problems. The fastest way to reach me is email — I read every message.
