Federico Serra

@federicoserra

Backend developer at ACLTI who developed Python microservices and integrated OpenAI into automation workflows.

At ACLTI, I developed Python microservices with FastAPI and Django, along with real-time data pipelines and event-driven integrations. I also integrated OpenAI into automation workflows and developed custom AI tools connected to internal microservices.

At Hackmetrix, I optimized PostgreSQL queries and indexes and designed, documented, and maintained REST endpoints with secure authentication and RBAC. I’ve also built Python backend features and ETL pipelines, and I use Claude Code for analysis, development, test generation, and task automation.
