Build a transcription product that scales without runaway costs

I build transcription and audio-AI products: self-hosted Whisper, job queues, long-audio processing, AI summaries with cost caps, APIs and payments.

Who it's for

Founders and teams launching transcription, podcast, meeting-notes or media-search products.

Transcription looks simple until the bills and the edge cases arrive: two-hour files, queues that jam, AI summaries that quietly fail, and per-minute API prices that eat your margin. I build transcription products that stay fast and affordable as usage grows.

What I build

  • Self-hosted speech-to-text (Whisper) on GPU servers, or a hosted API when that's cheaper
  • Job queues with priority tiers, crash recovery and GPU-aware concurrency
  • Long-audio and large-upload processing with real progress
  • Summaries, chapters, FAQs and chat, with spending caps and provider fallback
  • Speaker labels, translation and exports (PDF, SRT, VTT)
  • A public API with keys and credit plans; card and crypto payments

How I work

  1. 01

    Discovery

    A call and a short written scope: what we're building, what success looks like, and what's out.

  2. 02

    Build in weekly steps

    You see working software every week on a preview link, not a big reveal at the end.

  3. 03

    Launch and hosting

    I deploy to your servers or a VPS with monitoring, backups and HTTPS.

  4. 04

    Support

    I stay on to fix, measure and improve — the same developer who built it.

Questions

Self-hosted Whisper or a speech-to-text API?

It depends on volume. At low volume an API is simpler; once you transcribe thousands of hours, self-hosted Whisper on a GPU usually costs far less. I've done that migration and can model it for you.

Can it handle long files?

Yes. Audio is split into chunks with their own timeouts and stitched back with correct timestamps, and uploads are processed from disk so large files don't exhaust memory.

How do you keep AI costs under control?

Each feature routes to the cheapest model that does the job, with a daily spending cap and alerts, so a bug or a traffic spike can't run up a surprise bill.

Can I run several brands on one backend?

Yes. I run two transcription brands on one backend with isolated accounts, sessions and payment keys.

Have a product to build or fix?

Tell me what you're working on. I'll reply with questions or a first plan.
