Eduardo Dantas
Senior C++ software engineer working across performance-critical runtimes, protocols, reliability, developer tooling, and data safety.
I develop custom software for different industries, from an idea for a new application to improvements in an existing product. The scope and technology are chosen around the users, requirements, and constraints.
I investigate how systems behave, assess technical feasibility, and turn complex problems into focused engineering work. My experience spans C++ and Lua runtimes, client/server software, large-data tools, and build and release workflows across Linux and Windows. That same experience also supports technical work for code-model training, without identifying clients or exposing confidential project details.
OpenTibia is one of the domains where I apply that experience. Public contributions to its servers, clients, and editors sit alongside upstream C++ tooling contributions and private client engagements.
Confidential work & NDAs
Most of my client work is confidential and covered by non-disclosure agreements (NDAs). The projects shown here are a selection of public work and client-approved references, not a complete record of my work.
Confidential project details, code, and assets remain private.
