Dedicated OpenAI integration engineers

Hire OpenAI and ChatGPT developers who integrate the API like any other critical service.

Want ChatGPT-style features inside your own product, using the OpenAI API with your data, your login and your limits? DayDecoder hires OpenAI integration developers from Ahmedabad, India who have added GPT features to Laravel, Vue, React and mobile products, with retries, cost caps and overlap hours for the US, UK, Europe and Australia.

What our OpenAI developers integrate.

ChatGPT is the app; the OpenAI API is what we build with. The work is integration: auth, data, limits, errors and a good interface.

OpenAI appears in the stack of several projects on this site. The WhatsApp marketing SaaS uses OpenAI-assisted replies alongside chatbot flows. The AI customer support assistant generates ticket summaries and suggested replies on Laravel, Vue and PostgreSQL. The document intelligence platform combines OCR with OpenAI for extraction and classification. The AI SaaS platform and the AI SEO content planning tool use OpenAI for content and planning features. Our article on how to integrate AI into a Laravel or Node.js app describes the approach in detail.

An OpenAI hire treats the API like a payment gateway: a dependency that can be slow, fail or change. Calls run in queued jobs with timeouts and retries, responses are validated before they reach users, keys stay in your account, and costs are tracked per customer. When Claude or another provider fits better, the integration is written so the model can be swapped.

  • GPT features in your app

    Assistants, summaries, drafting and extraction inside your existing screens, using your users and permissions.

  • Structured outputs

    JSON responses validated against a schema, so the rest of your code can trust the shape of the result.

  • Reliability

    Queued calls, streaming where it helps, timeouts, retries and a fallback when the API is unavailable.

  • Cost and safety

    Per-customer limits, caching, moderation where needed and logs your team can review.

Skills and tool stack

OpenAI integration stack.

The OpenAI API inside the frameworks we use every day.

Typical work uses the OpenAI chat, embeddings and tool-calling APIs from Laravel or Node.js workers, streams responses to React, Vue or React Native interfaces, stores prompts and results in your database, and uses Redis for rate limits and caching. Claude is used where the product already has it or where it fits better.

A dedicated OpenAI developer, part-time, or hourly.

Owns every OpenAI integration in your product, including prompts, costs and model upgrades.

Part-time dedicated

Reserved days each week to add GPT features one at a time beside your team.

Hourly OpenAI help

A failing integration, a cost spike or a model upgrade that changed behaviour. Time-logged.

Hiring process

How an OpenAI hire starts.

We decide what the feature must never do before writing the prompt.

  1. 1

    Intro call

    Thirty minutes with the founder about the feature, your data and acceptable cost.

  2. 2

    Written proposal

    Dedicated, part-time or hourly, and the first feature with its limits.

  3. 3

    Keys and access

    An OpenAI project key in your account with spending limits, plus repository access under NDA.

  4. 4

    First feature in staging

    One integration end to end in staging, with logs, limits and test prompts.

  5. 5

    Weekly demo

    Behaviour on the same test prompts, the week’s cost and next steps, in your overlap hours.

OpenAI integrations delivered in your hours.

We work from Ahmedabad, India. Afternoons overlap with the UK and Europe, early mornings or late evenings with the US, and mornings with Australia. Prompt changes are reviewed with your team before release.

Model upgrades are tested against your saved prompts in staging first, so a provider update does not surprise your users.

  • United States

    Morning updates waiting in your inbox when the US workday starts.

  • United Kingdom

    Same-day overlap for calls, reviews, and decisions.

  • Europe

    Afternoon overlap with Central and Eastern European teams.

  • Australia

    Early-morning calls that fit the Australian workday.
