My Projects

Lexomni MCP turns the project's /_lexomni folder into a local knowledge base for AI agents, indexing Markdown and PDFs for search, chunked reading, and auditable incremental memory.

The project is an automation tool for performing operations in the financial market. Integrated with external broker/platform APIs. I worked as a fullstack freelance developer doing maintenance and development of new features, in addition to architecture optimization and complex API integrations. I also worked on scaling the service to support +1000 active users and service separation for better performance. The client does not allow explicit disclosure.

TriggerDesk-AI is a complete backend, developed by me, in NodeJS and MongoDB for real-time chat via websocket, which can be integrated into any frontend. The system works with markdown documents for modular prompt addition and an AI system (via OpenRouter) that assists N1 support, in addition to automating ticket opening, moderating chats and sending notifications to support. Using Support Context, the frontend can send user information such as settings and history to assist support. Authentication is done using the backend Secret and validating the token sent by the Front-end in the websocket handshake. The system includes Internal Notes, Ticket Assignment, Internal Groups, and image attachment (via MongoDB) among others.

During my internship I was the lead developer of the system for the Impact - Transformation center client. The project consists of: An authentication API, a main API, an administrative Front-end and a Front-end with PWA for clinic clients. I developed the implementation of various requirements and integrations between services, such as: Scheduling and calendar of appointments and training; Management and synchronization of meal plans and training plans between clinic and client; Patient history recording, including anamnesis, images, prescriptions, financial and doctor management of patient documents; Dynamic schedule for reception and control of doctors' schedules and agendas; Registration of schedule blocks and fittings, among other requirements.

Web application for consulting tax tables such as NCM and CFOP. The project proposal was born from a need to frequently consult NCM codes for support during my internship. The system has a cache system with IndexedDB to avoid unnecessary requests and storage of NCM code chapters. It also has a search system to find NCM codes in a normalized way.
