Chief Agentic Officer at ZapSign

André de Moraes Chaves

Nearly five years as CTO of a signature platform with 5M+ users and 70M+ documents across 81 countries — now building the agentic layer.

The swarm

From sole developer to reviewer of an entire team of agents.

Agentic orchestration, RAG as curation, multi-agent systems that converge and resolve — hammers that swing themselves.

The guardrail

The agent got hands. Not the key.

Governance, audit trails, and human-in-the-loop. Approve or reject what the swarm produces — you sit in the chair.

Hefesto Software House

One entity. The studio since 2016.

ANDRE DE MORAES CHAVES DESENVOLVIMENTO DE SOFTWARE LTDA. Custom software under CNAE 6201-5/01. Hefesto is the forge — not a second company.

PontoNet

The artifact the forge produced.

Time clock with WhatsApp and facial recognition, Portaria 671 compliance — operated by Hefesto.

The record

CTO → Chief Agentic Officer at ZapSign.

Public writing on agent auditing, HITL refunds, multi-agent orchestration, and corporate RAG — nine agents, 4,709 sources, and the discipline to verify the green check.

Writing

Essays on Medium — agentic systems, governance, and the craft.

Cooling

The forge banks its fire.

Open to conversations on agentic systems, governance, and custom software.
