01Selected work

Three systems. Each one had to survive contact with reality.

Product modernization, agentic commerce, and autonomous agents. Different constraints, different architectures, and real users on the other side.

01
FirstIgniteNew CRM and core platform / 2025 to now

A new CRM, plus the main platform's next foundation.

I built FirstIgnite's new multitenant CRM as a standalone app. Separately, I lead the phased modernization of the company's main platform into a Next.js and NestJS monorepo, including dedicated AI products and durable Temporal workflows evaluated with Braintrust.

PurchCo-founder / agentic commerce / 2025

A shopping agent that can finish the purchase.

I co-founded Purch for people and agents to search, compare, and buy through conversation. We built the chat product, a public x402 API, USDC settlement on Solana, Crossmint order flows, and durable social shopping infrastructure.

Autonomous agents with checkout, memory, and secure signing.

I built USDC checkout, Coinbase Onramp flows, multi-provider LLM orchestration, vector memory, secure key management, and one-click Docker deployment for agents across social and messaging platforms.

I am most useful when the problem is still messy.

Model behavior, infrastructure, and interface are one system. I work on all three.

02Experience

Production systems since 2020.

I have worked inside a bank, a global enterprise, and small teams where one engineer owns the whole path.

How can one agent infer what another is trying to achieve?

That question drives my MSc work at PUCRS. I study goal recognition, multi-agent reinforcement learning, and efficient search.
