Traxvio Case Study

Building a provider agnostic email layer that connects to any inbox over IMAP to read incoming leads and sends replies over SMTP in the owner's exact voice, handling authentication, connection pooling, and reliable syncing across different email providers.

Creating a pipeline to parse and digest unstructured business information, FAQs, services, and owner instructions, transforming them into a knowledge base the AI assistant can reference.

Optimizing the LLM context window by dynamically retrieving only the most relevant FAQs and business guidelines matching the specific intent of each incoming email.

To handle rate limits on the Gemini API, multiple API keys are stored in environment variables and rotated in a round robin order per request. If one key hits a rate limit, the system automatically switches to the next key.

On the Pro plan, a single account can connect up to 5 email boxes, each with its own custom AI instructions and tone. The system isolates incoming leads per mailbox, applies the right instruction set to each, and generates replies without mixing context between different inboxes.

Integrating a live Paddle checkout for subscriptions came with its share of bugs around billing flows, webhooks, and plan handling. I worked through each issue, learned the Paddle Billing v2 setup end to end, and shipped a fully working live checkout in production.
