Senior🎓
Top SchoolRenan Ferreira is a Senior Software Engineer with 12+ years in IT and seven years delivering high-impact solutions at large financial and technology companies, currently shaping Investments products that support a ~BRL 20B portfolio. He combines deep technical ownership with prior experience as an Engineering Manager, leading architecture and org redesigns that improved delivery cadence and reduced cognitive load across 30+ engineers. Renan has driven measurable business outcomes—reducing batch processing from 6 hours to ~20 minutes, achieving >96% availability, and contributing to ~BRL 100M/year funding cost reduction through automated yield products. He designs cloud-native, highly observable systems handling ~3K requests/sec and has led replacements of unreliable legacy financial platforms to improve accounting accuracy, collections, and regulatory exposure. With an MBA in Software Engineering from USP and a background in distributed systems and generative AI for architecture, he blends rigorous academic training with practical, product-focused execution. Less obvious: he pairs strategic domain thinking (DDD boundaries, journey-driven teams) with hands-on performance tuning to turn financial risk and delinquency problems into scalable revenue and reliability wins.
