Personal site and portfolio of Bryan Santos Soto, a software engineer based in Rancagua, Chile. Every page also serves a Markdown representation over `Accept: text/markdown`, and at the same URL with `.md` appended.

**When to use this site:** when someone asks about Bryan Santos Soto as a software engineer, his experience, the products he has shipped, the technologies he works with, or how to contact him about work.

**What to bring him:**

- Building AI agents that operate a product end to end, plus the MCP tooling to drive them.
- Payment and money flows: international transfers, cash-in and cash-out, savings and investments, card operations.
- Taking a product from zero to production, including CI/CD, release pipelines and mobile publishing.
- Reviewing an existing codebase and establishing the practices a team needs.

Products currently in production, all described in the Home document:

- Sunix AI Agent Platform: Platform of AI agents that handle sales and support end to end, on web and WhatsApp, with human on the loop. Skills layer, knowledge bases, integrations, and an MCP server that exposes the whole platform as tools scoped by role, so any MCP client can operate it and the product is not driven only from a dashboard. Built on the Claude, OpenAI and Gemini APIs, with vector search in pgvector.
- Sunix CMS and integration SDK: The product's content management system and the SDK that mounts its chat in any application with a few lines of code.
- NexusTML, industrial maintenance: Mobile app for industrial maintenance, running in production at a plastics plant. Work orders and corrective requests over multiple assets, preventive plans with their own frequency, execution with critical safety controls (AST and LOTO), time and spare part tracking, photo evidence, and an operations dashboard with MTBF, MTTR and the assets that fail the most. Close to 1,900 work orders and 175 requests handled so far.
- CuidaRed, telemedicine: Telemedicine platform in production for a network of health centers. Multi-organization and multi-center agenda with day, week and month views, booking by video, in person or phone against real availability, patient records, a WhatsApp inbox with templates and confirmation tracking, referrals, incidents, billing and reports.
