I solve architectural challenges differently. While standard engineering often relies on stacking repetitive templates, I focus on building holistic, high-signal systems where distributed data, AI, and real-time processes mesh seamlessly. People might not always track my exact process from the outside — but the end result works, precisely and predictably. Known as letoribo in advanced developer ecosystems, I use my core framework @letoribo/mcp-graphql-enhanced to turn abstract LLM reasoning into dynamic, instantaneous action. I build the infrastructure that allows AI agents to navigate and manipulate complex spatial and relational data under strict low-latency constraints. Core Focus: GraphQL & MCP Infrastructure: Scaling agentic workflows and providing language models with surgical, real-time access to distributed environments. Real-Time Systems Integration: Designing custom mutation interceptors and synchronized data-shuttles that bridge web-synapses with complex external simulations. Advanced Spatial Visualization: Building hardware-accelerated 3D interfaces to make intricate data structures tangible. If you are looking for a standard developer to close standard tickets, there are plenty of options. But if you need an architect to build something that breaks the mold — let’s connect.
