**Hi, I'm Simas. I build AI that takes the repetitive work off your team.**

Right now I build and run the AI behind customer support, payment disputes and marketing at a consumer subscription business. You work with me directly, from the first call to handover.

## What I build

- [Customer support](https://simasrazinskas.com/services#customer-support): Replies drafted from each customer's real orders. Your team approves them before they go out. Shipped: Replies in each customer's language. Every prompt change is tested against real tickets first.
- [Operations](https://simasrazinskas.com/services#operations): Disputes, refunds, reports and data syncs run as code that retries safely and shows what failed. Shipped: Chargeback evidence assembled from the order record, ready to file with each payment provider.
- [AI in your product](https://simasrazinskas.com/services#product-ai): Assistants and other AI features with measured quality, predictable cost and releases you can undo. Shipped: The chat service behind a consumer app's AI assistant, with analytics over every conversation.

## Recent work

Systems I built that run in production. Client names stay private.

- [A supervised AI support agent grounded in real customer data](https://simasrazinskas.com/work/ai-customer-support-agent): Support staff approve ready-made replies instead of writing every answer from scratch.
- [One governed platform for a company's internal AI automation](https://simasrazinskas.com/work/internal-ai-platform): New internal AI tools launch on one shared, access-controlled platform, not from scratch.
- [One AI chat assistant service for several brand apps](https://simasrazinskas.com/work/in-app-ai-assistant): Several apps share one AI chat assistant, and an LLM judge reviews every conversation.
