Experience

The roles, and what I actually owned inside each one.

Founder & Lead Architect

Laboratório Richard Wollyce

October 2026 - Presentlab.richardwollyce.com
  • Founded, engineered, and scaled the Laboratório Richard Wollyce ecosystem, currently my flagship business and source of full financial independence.
  • Built a qualified audience of 30,000 Instagram followers (@richardwollyce) and a highly engaged private WhatsApp community of 500+ members.
  • Created and teach proprietary curriculum covering attention engineering, scalable systems architecture, real-world AI integration, leadership, and positioning.
  • Engineered the end-to-end digital platform: member portal, multi-rail payment automation, content distribution pipelines, and engagement telemetry.
  • Achieved full operational autonomy and self-sustainability within two weeks of launch through rapid market execution.

Creator & Maintainer

Ulpia (Open Source)

August 2026 - PresentApache 2.0, ulpia.io
  • Architected and built a local-first memory and retrieval engine in Rust using SQLite FTS5 and Reciprocal Rank Fusion.
  • Implemented deterministic confidence gating to safely decline queries when no relevant context exists.
  • Created automated evaluation harnesses benchmarked against LongMemEval-S and adversarial test suites.
  • Shipped an MCP server with 4 read-only tools enabling local integration with Claude Desktop and AI clients.
  • Maintained 17,000 lines of Rust across 3 crates with 200+ unit and integration tests and 36 documented ADRs.

Tech Lead & Software Engineer

Casa Seth

April 2026 - PresentBrazil
  • Technical leadership of software architecture and delivery across digital products, checkout funnels, and revenue infrastructure.
  • Engineered custom checkout solutions with Pix and Mercado Pago, UTM attribution, server-side tracking, and operational dashboards.
  • Designed an idempotent image-generation pipeline with bounded concurrency, caching, and robust failure recovery.
  • Delivered and maintain BiblinhaPlay (Web/PWA and Expo/React Native) with streaming, gamification, and entitlement access.
  • Structured a modular TypeScript monorepo with TanStack Start, React, React Native, PostgreSQL, and Drizzle ORM.
  • Developed BiblinhaCraft using Three.js with procedural terrain generation and progressive region streaming.

Software Engineer

MG Laser

November 2025 - April 2026Franca, Brazil
  • Tech stack: TypeScript, React, Vite, Tailwind CSS, Node.js, Supabase, PostgreSQL, Linux VPS, EasyPanel.
  • Built and maintained an ERP that several teams used at once for inventory, sales and daily operations.
  • Replaced spreadsheet workflows with structured forms and automatic validation, and the manual-entry errors fell with them.
  • The large data tables were slow until pagination and targeted RPC calls went in.
  • Row-Level Security (RLS) and Role-Based Access Control (RBAC) decide which records a role can see, enforced in the database rather than in the UI.
  • I handled deployment, monitoring and the self-managed Linux VPS. One critical production outage, service back in under 10 minutes, no data lost.

  • Technical and operational support across the departments of a hospital, including the MV2000 patient-record system, service orders and day-to-day incident handling.
  • First point of contact for the Ombudsman department, and the link between reception, nursing, medical and technical teams when a workflow stalled.

Technical Instructor & IT Support Technician

  • Administered and maintained Windows lab workstations, software deployment, and networking infrastructure.
  • Provided daily technical support for students and faculty.

Projects

A retrieval layer for AI agents, a commerce operation, and a cybersecurity learning hub.

Attention Engineering, Systems & Integrated AI Platform

Laboratório Richard Wollyce

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.

  • Audience & high-density community: 30,000+ followers on Instagram (@richardwollyce) and an active private WhatsApp community of 500+ members.
  • Maturity & rapid business validation: launched two weeks ago and turned into my primary venture, delivering full professional and financial autonomy.
  • High-density curriculum: in-depth training on attention engineering, robust systems design, practical AI integrations, leadership, and positioning.
  • End-to-end platform architecture: custom member portal, automated checkout flows, streaming content delivery, and retention telemetry.

Local-First AI Memory Infrastructure

Ulpia

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.

  • Dual-scorer engine combining declared keyword indexing with SQLite FTS5 full-text search via Reciprocal Rank Fusion.
  • Deterministic confidence gating for abstention: safely declines 28 of 30 out-of-scope queries in blind adversarial benchmarks.
  • Sub-millisecond hot-path latency (0.68 ms p50, 1.16 ms p95 in-process) with a 97% abstention rate on LongMemEval-S.
  • Integrated Model Context Protocol (MCP) server providing 4 read-only tools for Claude Desktop and agent runtimes.
  • Git-anchored privacy model: untracked files are strictly excluded from indexing and serving.
  • Roughly 17,000 lines of modular Rust across 3 crates, single runtime dependency, over 200 tests, and 36 documented ADRs.

Infoproducts, Commerce & Conversion Systems

Casa Seth

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).

  • Complete revenue instrumentation: first-party browser and server-side tracking, event deduplication, UTM attribution, and automated reconciliation.
  • Idempotent image-generation pipeline with bounded concurrency, caching, telemetry, and automated retry mechanisms.
  • Modular TypeScript monorepo sharing core domain logic, UI libraries, and transactional flows across independent funnels.
  • BiblinhaPlay in production for ~500 subscribers across Web/PWA and Expo/React Native, featuring entitlement control and protected media.
  • BiblinhaCraft: interactive voxel engine built from scratch in Three.js with procedural terrain generation and mobile touch controls.
  • Digital checkout integrated with physical fulfillment: address validation, print-ready asset processing, and order lifecycle queues.

Cybersecurity Learning Hub

RoadToCyberSec.com

A cybersecurity learning path and resource hub for beginners, developers, and non-technical professionals.

  • I wrote and organized the material myself.
  • Modules cover fundamentals, threat analysis, password security and MFA, safe browsing, device hygiene, incident response, network fundamentals, and digital evidence handling.
  • It runs on Mintlify, with a searchable documentation index and a path you can follow in order.

About Me

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.
