DevTeam Does AI Development Differently

We go beyond basic API calls — delivering structured AI systems aligned with your business goals.

Goal-Oriented Architecture

We focus on achieving your business goals — not just implementing requested features.

Chained API Workflows

We combine multiple AI APIs to build seamless input → processing → output pipelines.

Secure Logging & Storage

All user inputs and AI responses are securely logged and stored in your database.

RAG-Based Retrieval

Store internal documents in a vector DB and enable GPT-powered contextual search.

Accurate Cost Estimation

We analyze API usage patterns to help you forecast operating costs with confidence.

AI Response Tuning

We optimize system prompts and handle edge cases to maintain consistency and quality.

Pre-Processing of Data

We automatically clean and format your text, images, and audio before AI processing.

Post-Processing of Results

We refine AI outputs with filtering, sorting, and formatting to ensure usable results.

Our Development Workflow

From start to finish — we follow a transparent and professional process.

  • 1. Inquiry & Quote Request
    Submit your request via the Request a Quote page, and we'll respond within 1 business day with a detailed estimate and 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 Environment Setup
    On the same day or next, we configure and deploy the project to your EC2 instance or our own server. Video call support is available if needed.
  • 4. Initial Delivery
    We deliver the first working version ahead of the agreed schedule. All features are deployed to a live server for preview.
  • 5. Feedback & Revisions
    During the review period, we gather and implement your feedback. Optional video meetings ensure fast communication.
  • 6. Final Delivery & Remaining Payment
    Upon final delivery, the remaining balance is paid. We provide the full source code and offer 1 month of free bug fixes.
