Senior Desenvolvedor backend

Backend developer with over 13 years of experience in IT. For the past 5+ years, I have been building and evolving a backend platform for business process automation: developing services in Go/Golang and Haskell, designing APIs, integrations, business logic, data schemas, and inter-service communication.

My primary focus is backend development in Go: microservices and backend services, REST/JSON-RPC APIs, PostgreSQL, Redis, HTTP/API integrations, queues, testing, and distributed systems patterns. I can also take responsibility beyond application development, including service architecture design, Kubernetes infrastructure, CI/CD, Git/GitLab/Forgejo, monitoring, and production/staging environment operations.

I have experience as a Tech Lead / Team Lead and Solution Architect: task decomposition, code reviews, technical leadership, developer hiring, collaboration with C-level executives, and translating business requirements into technical solutions.

In Haskell, I have worked extensively with functional programming idioms and advanced type system features: pure functions, composition, ADTs, type classes, monads/effects, domain modeling, business rules, and architectural invariants.

I am experienced in AI-assisted software development: I use Claude, opencode, and pi/coding-agent, and know how to organize the harness, working context, and rules for AI tools so they can effectively support development, refactoring, testing, and code maintenance.

I am particularly interested in roles where Go backend development is combined with responsibility for architecture, API quality, integrations, data, and service operations. I value a pragmatic engineering approach: clear decomposition, maintainable code, observability, deployment automation, and a strong connection between technical decisions and business needs.

Professional interests: functional programming, Haskell, Nix, Vim, split keyboards, and the practical use of AI tools in software development.
