## About

Halcyon Tech is a Brazilian software studio built on one conviction: most technology fails not because it was badly built, but because it was built before anyone understood the problem.

So we start there. Every engagement opens with discovery - interviews, data and business context - before a single line of code is written. Scope becomes a consequence of the problem instead of a guess, and you know what you hold at the end of every stage.

What we do:- Custom software: systems and platforms built for your exact problem, not a generic mold- Digital products: web and mobile people use every day- Discovery & strategy: immersion in your business to surface the right problem- Cloud & data: scalable infrastructure and data that turns into decisions- Artificial intelligence: models and automation applied where they create real value, not hype- Embedded systems: firmware and connected devices, reliable and field-ready- Product design: refined aesthetics with function that holds up

How we work: short, visible delivery cycles, so you watch the result move instead of waiting for a reveal. Architecture that is observable and scales with the business. And direct access to the engineers doing the work - we are a founder-led team, not a layer of account managers.

Recent work includes a bureau data integration service for a credit recovery operation, enriching customer records at scale: Java and Spring Boot on a hexagonal clean architecture, Cosmos DB, containerized, with automated API testing. Across the team our stack spans Java, TypeScript and React, Python, PostgreSQL/PostGIS, cloud infrastructure and applied AI - LLMs, RAG and analytics.

We are three software engineers who started Halcyon to build things that have value. We think that begins with listening.

Engineering with the strength of giants. Listening with the eye of a bird.
