About me
Six years in startups taught me to own the outcome.
I have helped build everything from early-stage websites to SaaS applications serving thousands of users. My focus is on delivering software that moves the business forward, whether that means learning something new, working across teams, or doing what it takes to ship.
- I work across the whole stack, from database to interface.
- You get a written scope, so you know what you are paying for.
- I document the work, so your product never depends on just me.

Four stages from idea to launch.
A clear process protects your budget. You always know what is being built, what comes next, and what has changed.
Stage 01
Scope
We start with what the product needs to achieve. I turn that into a written scope that says what is included and what is not.
Before kickoff Stage 02
Plan
I break the work into phases in the order they depend on each other, each with a clear definition of done.
Before code Stage 03
Build
Work ships phase by phase, so you can test real software early. New ideas are discussed and agreed before they change the plan.
Phase by phase Stage 04
Hand over
You get working software, documentation and a deployment setup, so the product does not depend on one person.

Common questions before we start.
Not sure yet?
Send a short note about what you are building. I will tell you honestly whether I am the right developer for it.
Write to meWhat kind of projects do you take on?
SaaS products, MVPs, internal tools, mobile apps and business websites. I have worked in finance, recruitment, logistics, education, ecommerce and workspace management.
Can you work with our existing team?
Yes. I have led builds from the start, and I have joined existing products to add features and maintain them, including Banklingo, SofiaPulse and Greenomy.
Which technologies do you use?
Mostly React, Next.js, Vue and TypeScript on the frontend, and NestJS, Node.js or Spring Boot with PostgreSQL on the backend. I can also work in the stack you already have.
How do you price a project?
Most builds are priced as a fixed fee against a written scope. Anything outside that scope is discussed and agreed before work starts. Send me the details and I will tell you how I would approach it.
Do you work with clients outside the US?
Yes. I am based in Tennessee and work remotely, and I have worked on products for teams and users in the US, Nigeria and Europe.
What do I get at the end of a project?
Working software, the source code, documentation and a deployment setup. The exact handover is agreed in writing at the start, so your team or your next developer can carry on with confidence.

Ready to build something that works?
