What I'm looking for

I’m looking to build scalable backend and event-driven systems in cloud environments, optimizing SQL/data performance and reliability for fintech and AI-driven products, with room to lead architecture and mentor teams.

I’m a Backend Developer with 3+ years of experience building production-grade backend systems, cloud-native services, high-volume data pipelines, and performance-critical financial platforms. I specialize in Java 17, Spring Boot, REST APIs, SQL optimization, ORM/Hibernate performance, Docker, AWS, and distributed/event-driven architectures.

In fintech, I launched backend services for a mobile banking platform supporting over USD 200K in monthly investment, card, and peer-to-peer payments. I reduced high-frequency database query latency by 85% through SQL execution plan analysis, ORM/Hibernate bottleneck fixes, and migrating critical workloads to optimized stored procedures, while improving reliability and maintainability with modular boundaries, typed DTOs, and structured logging.

I also build cloud and AI/data systems end to end—architecting event-driven routing with AWS Lambda for autonomous call handling, creating cloud cost-analysis automation to reduce spend by over USD 2,000/month, and engineering multilingual sentiment scoring with HuggingFace BERT. As a co-founder, I delivered an AI resume-evaluation backend pipeline that reduced candidate screening time by 95% and helped grow a SaaS platform recognized as Entrepreneurship World Cup Bolivia Winner.
