Senior🎓
Top SchoolJerson Peña is a seasoned Development Team Lead with over a decade of experience building scalable, production-ready applications and leading cross-functional engineering efforts. Currently at Bytesimal he architected Taxera, an AI-driven invoice processing SaaS that combines NestJS, Angular 21, multi-provider LLMs and Google Vision to automate extraction and validation at scale. He’s comfortable across the stack—Elixir and Java backends, Angular/React frontends, PostgreSQL performance tuning, Redis/BullMQ pipelines, and cloud deployments—and favors Hexagonal/Clean/DDD patterns for maintainable systems. Notable wins include cutting PostgreSQL query times from 30 seconds to 20 milliseconds and automating 100+ hours of manual work through intelligent system design. Beyond shipping features, he builds custom tooling like ANTLR-based query languages and real-time SSE batch processors, showing a mix of architectural rigor and practical engineering. Based in Santiago de los Caballeros, he combines a hands-on coding mindset with a continuous appetite for emerging technologies and best practices.
