Full-Stack Developer · Node & Python · Brazil

Where classical craft meets engineering.

τέχνη — the Greek root of technology — means art, craft, mastery. Four years building software end to end: microservices in Node and Python, distributed systems and AI agents on the back, Vue and React on the front — with the patience of a sculptor and the rigor of an engineer.

I · Σοφία

I believe software is a form of architecture — invisible, yet inhabited every day.

The Greeks drew no line between art and technique. To them, doing something well was one and the same, whether an amphora or a geometric proof. I carry that into code: elegance and function do not compete — they require each other.

Full-stack developer in Node.js/TypeScript and Python. On the back end I build APIs and microservices with Fastify and Express, FastAPI, asynchronous pipelines with BullMQ and Redis, messaging with Kafka, PostgreSQL and Neo4j, all containerized with Docker — lately on distributed systems and AI agents. On the front end, Vue with Vuetify and React with Next.js.

  • SOLID over cleverness.
  • Clean Code and Design Patterns as discipline.
  • Performance and integrity > impressing.

The Craft

Four domains, one discipline.

Α

Frontend

τὸ φαινόμενον — what shows itself

Interfaces like temples: proportion, rhythm and light. Vue with Vuetify, React with Next.js, and an obsession with the detail no one notices — but everyone feels.

Β

Backend

τὰ θεμέλια — the foundations

The invisible structure that holds up the visible. APIs and microservices in Node.js/TypeScript — Fastify, Express, TypeORM — with asynchronous pipelines on BullMQ and Redis, built to scale and outlast a season. Python and FastAPI when the project asks for them.

Γ

Architecture

ἡ τάξις — the order

Decisions made today that tomorrow's self will thank. Distributed systems, messaging with Kafka, AI agents, clarity and the courage to remove before adding.

  • Event-Driven
  • AI Agents
  • SOLID
  • CI/CD
  • Docker
Δ

Craft

ἡ ἀρετή — excellence

It's not the framework, it's the craft. Readable, tested, honest code — made to be read by humans.

  • Clean Code
  • Design Patterns
  • Testing
  • Performance

Experience

Where craft met the real world.
