5 years building mission-critical backend systems in Go for logistics & risk management. Reliable, high-throughput and well-tested.
I'm a Go backend developer with 5 years building reliable, high-throughput systems. I care about clean architecture, well-tested code and services that stay observable and up under load. I've led projects from zero to production and spent 2+ years as the sole developer on mission-critical systems, so I'm comfortable owning a service end to end. I started full-stack with React and TypeScript and still move across the whole stack, but my focus is APIs, distributed systems and backend built to last.
how I turn ambiguity into shipped software
I treat AI as leverage on judgment, not a replacement for it. It moved my time toward the decisions that actually matter. My cycle is deliberate and spec-driven: I refine the problem into a clear spec before touching code, analyze trade-offs and edge cases, then implement in small, verifiable steps. And it doesn't stop at the code. I bring it into the whole delivery chain: clear pull requests, validation guides QA can actually follow, and technical documentation. That speeds up the team's work and raises its quality, not just my own. The result isn't just faster code; it's more time on architecture and less on boilerplate, with handoffs the whole team can trust.
where I've worked
spoken & written proficiency
core focus on Go and distributed backend systems
a few things I've built
Enterprise full-stack platform (Go + React monorepo, 5 integrated apps) validating people, companies and vehicles across dozens of internal and external integrations: OCR, computer-vision facial checks, real-time chat, and async record sync over message queues. A large codebase serving thousands of companies at high, business-critical query volume.
Full-stack video-call platform with real-time checklists for live participant verification: recording, automatic PDF reports, webhooks, multi-tenant white-label, OAuth2 and S3 storage. Used in production for higher-risk cases, stable with zero urgent fixes since launch.
Go REST API acting as a smart broker for government and AI integrations to validate documents and personal data, with intelligent caching, automatic fallback between providers, and a full audit trail. Handles high request volume, with caching that cut external-API cost by 70–80%.
Enterprise registry for records and restrictions (Go + React) with a central REST API for identifier-based checks (CPF, CNPJ and plates across 6 Mercosur countries), granular multi-tenant RBAC, bidirectional webhooks and clean/DDD architecture. Tens of thousands of checks, 24/7.
