Mateus Miri

At Smarten Venture Builder, I lead the technical direction and backend architecture for Agronota, a tax-compliance product. I translate regulatory requirements into system decisions alongside Commercial, Customer Success, and Legal stakeholders.

I built an internal MCP-based analytics system that increased automation accuracy by 30% and reduced invoice-issuance time by 35% within two weeks. I also identified and led an emergency fix for a billing-model defect that was eroding monthly recurring revenue by 24%.

I architected a tax-document bookkeeping automation pipeline using Go, PHP, PostgreSQL, and Redis, then integrated AI to cut processing time by 97.7% and raise automation coverage from 87% to 99.5%.

Earlier, I improved peak-load throughput by 93% by redesigning a Go and PostgreSQL query strategy, restored a long-broken RabbitMQ service, and built Go libraries and CLIs adopted across the company. I value clear technical judgment: deciding what to build, what to fix first, and how to use AI safely under rigorous code review.
