I help founders and teams ship AI-powered products and automation that hold up in production — from LLM features and payment flows to field apps that keep working offline. You get a spec first, fast delivery, and an engineer who owns every trade-off.
Add chat, summarisation, extraction or an OpenAI-compatible gateway to your product — with cost metering, rate limits, fallbacks and prompts you can version. I built Vensix, my own AI gateway, the same way.
Best for: products that need AI features that behave in production and don’t surprise you on the invoice.
QRIS / Midtrans / Pakasir payments, Telegram and WhatsApp bots, webhook pipelines and auto-fulfilment. Payments are verified server-side, delivery is idempotent, and every state change leaves an audit trail.
Best for: businesses still doing orders, payments or notifications by hand.
End-to-end builds — web, Flutter mobile or Cloudflare edge — or a written review of a system you already run: failure modes, security surfaces, data integrity and running cost, with prioritised fixes.
Best for: teams a few weeks from launch, or a system that misbehaves under real users.
