I build products that solve real problems and grow revenue.

Software engineer and product builder for startups and teams. I turn messy problems into fast, scalable products that convert visitors into customers, from design and frontend to backend and everything between. The goal is never just a website; it's growth you can measure.

01About

Products that start with a question and end in production.

I'm Folorunsho Ahmed Olajide, known online as Crazy Codes. I solve business problems with software. I sit at the intersection of product, design, and engineering: the person who can wireframe a flow in the morning and ship the API by evening.

Over six years I've designed brands and shipped 34+ web and mobile products for startups across real estate, fintech, and SaaS. I don't just make things look good; I build products that win users, keep them, and turn attention into revenue.

If you need someone who can own the full journey, from brand and user experience to scalable architecture, and cares about your bottom line, we should talk.

Focus: Problem solving & growth

What I do

Product Design

Wireframes to polished, high-converting interfaces designed to turn visitors into paying customers.

Web & App Development

Fast, accessible frontends and solid backends in React, Next.js, Node, and Postgres, built to sell and scale.

Branding & Identity

Visual systems that make your product feel trustworthy and premium, so people feel safe paying you.

Scalable Systems

Architecture that stays fast and calm as usage, revenue, and your team grow.

03How I work

Not just code outcomes you can measure.

I care about the business behind the product. Every decision is weighed against one question: will this help you make or save money?

Understand the problem

Before a single line of code, I dig into your users, goals, and numbers. The best products start with the right question, not the flashiest feature.

Design & build the solution

I design clean, high-converting interfaces and back them with scalable systems, so the product looks premium and holds up as you grow.

Ship, measure, grow revenue

I ship fast, watch how real users behave, and iterate on what moves the metrics that matter: signups, retention, and revenue.

04Stack

Tools I reach for most problems, most days.

Opinions held loosely. The stack bends to the product, not the other way around.
