8 Reasons Why DevTeam Stands Out

We build MVPs designed to scale to full production.

Developer-Built Architecture

No pre-made solutions — we craft the front and backend from scratch, enabling full scalability and flexibility.

No No-Code Shortcuts

We write every line of code with clarity and maintainability in mind — no magic boxes, no tech debt.

Full Source Code Delivery

You get 100% of the source code upon delivery, plus one month of free bug fixes and technical support.

Hardened Security

All projects meet SSL Labs A-grade security standards with a stable and secure tech stack.

SEO-Ready Foundation

Built with server-side rendering for maximum search visibility — ideal for early user acquisition and validation.

Blazing-Fast Load Time

Pages load within 1.8 seconds (FCP), improving engagement and reducing bounce rate significantly.

Rapid MVP Launch

We leverage proven templates and frameworks to focus on core functionality — cutting build time dramatically.

App & API Development

Beyond the web — we also build mobile apps, API servers, Bluetooth integration, and AI API connections.

All quotes may vary depending on the features and complexity of your project.
Domain and server costs are separate. If you don't have your own EC2 server, DevTeam provides one free for 1 month.
Every project includes full source code, EC2 deployment support, and 1 month of free bug fixes.

Project Workflow

From start to finish — a transparent and professional process.

1. Inquiry & Quote Request

Submit your request via the “Request a Quote” page. We'll respond within 1 business day with a quote and estimated timeline.
2. Contract & Initial Payment

Development begins after a 50% upfront payment. If using platforms like Wishket, service fees are split 50/50. Performance bonds can be issued upon request.
3. Server Setup

On the same day or the next, we set up your EC2 environment or our own server. Video call support is available if needed.
4. Initial Deployment

We deliver the first version of your product ahead of the agreed timeline. All features will be deployed to a live server.
5. Feedback & Revisions

During the review period, we gather your feedback and apply updates. We also offer video meetings to streamline communication.

I need urgent development. Is that possible?

Yes, we offer expedited development services.
We can accelerate your timeline by including night and weekend work, with additional charges.

I already have design mockups. Can you use them?

Absolutely. You can send Figma, PDFs, or images and we’ll reflect them as closely as possible.
Note: the more UI precision is required, the more time and cost may increase.

Can you build mobile apps too?

Yes, we develop cross-platform apps using Flutter.

Do you offer maintenance services?

Yes. We provide 1 month of free bug fixes after delivery.
Ongoing maintenance is available monthly or per case, based on standard Korean developer rates.
