AI development

AI features that fit the product you already have

Abdur Rehman is an AI developer who adds LLM features to existing products: summaries, reply drafting, voice-to-notes and document extraction, using Claude or OpenAI with streaming, usage limits and cost tracking. He built the AI pipeline behind Scribeside, which turns recorded patient visits into structured clinical notes.

This is for you if

  • Your product would be better with one specific AI feature, and you do not want to rebuild it around AI.
  • You have a prototype calling an AI API, and it is slow, expensive or unreliable.
  • Your users type up the same kind of text over and over.

What you get

One feature, done properly

A working AI feature inside your app, admin panel or workflow, with streaming responses so it feels instant.

Prompts you can change

Instructions live in settings, not buried in code, so the behaviour can be tuned without a deploy.

Cost and reliability controls

Usage limits, cost tracking, logging and a fallback model, so one provider outage does not take your feature down.

Your accounts, your keys

Deployed to your infrastructure with keys kept on the server and setup notes for your team.

What AI features are worth adding to an app?

The ones that remove typing and reading your users already do. The most reliable wins are summarising long content, drafting text for a person to approve, turning speech into structured notes, and pulling fields out of documents.

These work well because a person stays in the loop. The AI does the first pass, and your user reviews it in seconds instead of writing it in minutes.

How do you stop AI features from being slow or expensive?

By choosing the smallest model that does the job, streaming the response so users see it immediately, caching what repeats, and capping usage per customer. Cost tracking is built in from the start, so you see what each feature costs before it surprises you.

Which AI providers do you work with?

Claude and OpenAI directly, or many models through OpenRouter. For voice I use speech-to-text services such as Deepgram and Whisper. I pick based on your task, speed and budget, and keep the provider swappable.

Where I’ve done this

Scribeside

A recorded visit is transcribed and written up as a structured clinical note that streams onto the screen for the doctor to review.

Presence OS

AI drafts on-brand posts for each employee, inside the rules the company sets.

He is incredibly proactive, catches edge cases most developers miss, and genuinely cares about the success of the business he is building for.

How a project goes

  1. Pick the feature

    We choose one feature with a clear payoff and agree what good output looks like.

  2. Prototype on real data

    I test models and prompts on your own examples and share results early.

  3. Build it into the product

    Streaming, limits, logging and error handling, wired into your existing app.

  4. Ship and hand over

    Deployed on your accounts with notes on how to tune and monitor it.

Questions people ask

Straight answers. If yours is not here, ask me.

Ask me directlyI read and answer every message.

Can you work inside our existing codebase?

Yes. I add the feature to your app as it is, following your stack and conventions, rather than asking you to move to mine.

What does it cost to run?

AI usage is billed by the model provider. I add usage limits and cost tracking so you can see and cap your spend.

How does pricing work?

After a short call I send a fixed quote for an agreed scope, so you know the cost before work starts. Larger builds are split into milestones.

Do I own the code?

Yes. The code lives in your repository and runs on your accounts. You own the code, the accounts and the data, so you are never locked in to me.
