The roles, and what I actually owned inside each one.
A retrieval layer for AI agents, a commerce operation, and a cybersecurity learning hub.
Attention Engineering, Systems & Integrated AI Platform
My flagship ecosystem and training platform. Teaching attention engineering, systems architecture, integrated AI, leadership, and market positioning. Achieved rapid product-market validation: 30,000 Instagram followers, a private 500-member WhatsApp community, and complete financial independence within its first two weeks.
Local-First AI Memory Infrastructure
Open-source memory layer for AI agents, written in Rust and released under Apache 2.0. Deterministic RAG without embedding models: fuses keyword indexing and full-text search via Reciprocal Rank Fusion to deliver offline, reproducible, and verifiable retrieval with reliable abstention.
Infoproducts, Commerce & Conversion Systems
Digital commerce ecosystem and infoproducts house where I lead engineering and platform architecture. Spans customer-facing applications, payment infrastructure, reconciliation, and BiblinhaPlay (subscription platform with ~500 active users).
Cybersecurity Learning Hub
A cybersecurity learning path and resource hub for beginners, developers, and non-technical professionals.
What I know how to do, grouped roughly by where it sits in the stack.
Retrieval and memory infrastructure for AI agents in Rust, featuring rigorous benchmarking and local-first architecture.
I lead architecture and delivery across web and mobile products, and I am still the one on call after they go live.
Checkout architecture, financial reconciliation, and reliable server-side event tracking with idempotency.
Responsive web, PWA and native mobile apps, up to and including streaming interfaces and touch-first 3D gameplay.
I design the APIs, the authentication, the data models, and the protected-content flows that web and mobile both read from.
Deployment, testing, monitoring, incidents and recovery, on managed services and on Linux boxes I administer myself.
I am a Systems Architect, Tech Lead, and Full-Stack Software Engineer combining deep technical craft with high-leverage distribution and conversion systems. My flagship venture is Laboratório Richard Wollyce (lab.richardwollyce.com), an ecosystem where I teach attention engineering, scalable systems architecture, integrated AI, leadership, and market positioning.
Backed by 30,000+ followers on Instagram and an engaged 500-member WhatsApp community, Laboratório scaled to immediate product-market fit and full financial independence within its first two weeks, proving the leverage of pairing engineering rigor with audience distribution.
Concurrently, I am the creator of Ulpia (open-source local-first memory layer for AI agents written in Rust, featuring deterministic RAG under Apache 2.0) and Tech Lead at Casa Seth, where I lead payment infrastructure, subscription platforms, and revenue engineering.
I prioritize clean abstractions, clear domain boundaries, idempotent workflows, and automated testing to ensure system resilience. Based in Franca, Brazil, I work remotely across Latin America and am open to relocation to Santiago, Chile.
