Backend Engineer
Júlio Silva
I design and build backend systems that scale — REST APIs, distributed services, and data pipelines using Python, Django, and Go.
About
Backend software engineer with 4+ years of production experience. I specialize in API design, distributed systems, and performance-critical backends — building services that stay reliable under load, integrate cleanly with external systems, and remain maintainable as they scale.
Currently at GuestReady/RentalReady, contributing to a Django-based property management platform that orchestrates availability, pricing, and channel distribution for thousands of properties across Booking.com, Airbnb, and Vrbo. Previously at Wavecom, I designed microservices in Python and Go, built real-time monitoring infrastructure for HPC clusters, and delivered ETL pipelines from greenfield to production.
I care about the hard parts: data consistency, service boundaries, database performance, and clean API contracts. Working towards a technical leadership track — writing code every day.

Task management app built with Django and PostgreSQL. REST API design with structured data modeling and a maintainable backend architecture.
Because someone has to be held accountable. Log production incidents, name the culprit, and watch the shame leaderboard do the rest.
Real-time monitoring platform for HPC clusters. Aggregates metrics from distributed compute nodes using Python collectors, VictoriaMetrics as the time-series backend, and Grafana for visualization.
