Senior Software Engineer — Go, Node.js, TypeScript | Product & AI Vision

Looking for a backend engineer who can deliver robust code and understand the business implications behind each feature? That's been my daily work for 8 years.

I design and develop reliable and scalable backend systems (Go, Node.js, TypeScript, SQL/NoSQL), from architecture definition to production deployment. At Lydia, I currently manage the backend for fees and subscriptions for a fintech company handling critical flows — a context where reliability is non-negotiable.

What sets me apart: a sharp product vision.

I don't just execute a ticket. Before coding, I make sure to understand the business "why" behind each technical evolution — which allows me to challenge specifications, propose more relevant alternatives, and deliver solutions that truly serve your objectives, not just the requirements document.

I'm also curious and proactive about AI as a development aid tool: I continuously train myself on these new practices to accelerate deliverables without sacrificing quality, an issue I consider central to any backend project today.

What projects can I help you with:

Backend architecture design and development

API design and implementation

Technical refactoring and technical debt reduction

Technical integrations with clients/partners

Code review, implementation of team best practices

Data pipelines (ingestion, migration)

Main stack: Golang, Node.js, TypeScript, React, MongoDB, ElasticSearch, GCP, PostgreSQL, Gitlab, Github

Let's discuss your project — I'll be transparent about feasibility, timelines, and the best way to achieve it.
