Hi, I'm Olusegun Ibraheem
I architect systems that scale — and ship them to production.
Senior Full-Stack Engineer with 8+ 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 8+ 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 — currently serving as Engineering Lead at Tech1M while experimenting product ideas on the side.

Products I've built and shipped
A selection of some of my recent works
InnerMost
A mind-reading game — gamified from a childhood prediction trick I practised. 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
An agentic RAG assistant that answers questions from your own documents with real citations, and takes scoped, audited actions through a three-tier risk model mirroring production agentic systems.
Veci CRM
A production multi-tenant CRM built from scratch for Veci Technologies — Laravel 13, domain-driven architecture across 20+ bounded contexts, Go microservices for import and email ingestion, live in production.
More builds
Internal services and client engagements — filter by category.
AWS Image Pipeline
Serverless image processing pipeline on AWS — an S3 upload triggers a Lambda that generates a thumbnail and publishes a completion event via SNS, entirely defined in Terraform.
X-Socials Platform
A four-service distributed social media platform — Node.js API, Next.js frontend, Laravel admin panel, and a FastAPI hybrid AI moderation engine — built end-to-end as an architectural showcase.
WriterIX
Multi-tenant AI-powered blog generation SaaS — from topic ideation to published post, fully automated.
xurl.fyi — URL Shortener
High-performance URL shortener built on a Go API backend and Next.js frontend.
History Graphic Generator
Go microservice that renders shareable "This Day in History" social graphics, integrated with the WriterIX content pipeline.
WriterIX AI Pipeline
Async AI microservice powering WriterIX content generation — FastAPI + Celery with Gemini/Groq LLM orchestration.
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.
