Oluwagbemi K.

Senior Full-Stack Developer | React | NodeJS | JavaScript | Python

I have shipped production software on a trading platform serving 490,000 active clients and processing 123 million trades annually. I have built over 200 real estate websites on a platform operating across 140 countries. I have taken a startup MVP from zero to acquisition. I hold an MSc in Software Engineering. This is what 8 years of serious engineering experience looks like. My stack covers the full depth of modern web development. I do not just write code. I architect systems, own deployments, and think about the product from a business angle. I also help manage FalAgency, a growth engineering agency, which means every system I build is evaluated against real performance and business outcomes, not just technical requirements. 💥What working with me actually means for your project: 💥 You get a developer whose code has been tested at real scale, not in side projects. You get full ownership across frontend, backend, APIs, and deployment with no handholding required. You get production-ready AI integration where necessary covering NLP pipelines, LLM connections, and FastAPI microservices. You get direct communication, realistic timelines, and no surprises mid-project. You get a product-minded engineer who thinks about growth and outcomes, not just delivering features. 💥Quick proof of my work from real production environments:💥 Beyond my full portfolio, here is a quick look at a few high-scale production environments I have shaped: Tickmill (fintech) - Frontend engineer on a live trading platform with 490,000 active clients and 123 million trades processed annually.
