Hi, I’m Marvin, a software developer with more than 12 years of experience.

I help people turn ideas into working software. I also work on existing products that need new features, better performance, or someone to figure out why things aren’t working as they should.

My work covers AI, machine learning, full-stack development, backend systems, SQL databases, Web3, and UI/UX design. I enjoy projects where these areas come together—for example, building an application that needs a clear interface, a reliable backend, and AI features that are genuinely useful.

Here’s what I can help you with:

- Web applications and dashboards: Building a new product, finishing an incomplete application, or improving an existing one.

- AI and machine learning: Adding AI features, connecting models to your application, and developing tools around your data and workflows.

- Backend development and SQL: Building APIs, connecting services, designing databases, troubleshooting slow queries, and improving application performance.

- Web3 development: Building blockchain-connected applications, wallet integrations, and transaction workflows.

- UI/UX and product design: Planning user flows and designing interfaces that make complicated tasks easier to understand.

You don’t need to arrive with a perfect technical specification. A clear explanation of the problem, a few screenshots, or an example of what you’re trying to build is a useful starting point.

Before development begins, we’ll discuss what the software needs to do, who will use it, and any constraints around your budget, timeline, or existing system. From there, we’ll agree on a practical scope and clear deliverables.

I prefer straightforward solutions over adding technology a project doesn’t need. I pay attention to how the application works for users, how its different parts fit together, and how easily another developer can maintain it later.

For larger projects, we can divide the work into milestones so you can review progress and give feedback along the way. Testing, documentation, deployment, and handover can be included in the agreed scope.

Send me a short overview of your project, what you already have, and where you need help. We’ll work out the scope, timeline, and price before getting started.
