Hi, I'm Olusegun Ibraheem
I ship full-stack products, and AI features you can measure, trace and trust.
Senior engineer with 9+ years across fintech and global workforce platforms. I build the product end to end (React and Next.js, Python, Go and Node backends, AWS) and treat the AI layer like any other production system: replayable, tested, traced and honest about what it does not know.
About
Production full-stack engineering, with AI held to the same standard as everything else.
I'm a Senior Full-Stack Engineer with 9+ years architecting and shipping production systems for fintech and global workforce platforms. My core is event-driven backends in Python, Node and Laravel, React and Next.js on the front end, and the AWS, Docker and CI/CD layer that gets it all into production. Over the last few years I've moved into AI engineering: RAG pipelines, stateful LangGraph agents, and the tooling that makes them trustworthy, including deterministic replay, trace-based evals and OpenTelemetry. I care about system design, testing and observability, and about leaving every team's engineering bar higher than I found it.

Recent projects
A selection of some of my recent works
Argus — Traceable AI Agent
A tool-calling shop agent you can replay without an API key and inspect span by span. Python/FastAPI agent core, OpenTelemetry traces, a customer storefront, and a trace-first inspector, all deployed.
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.
