What I'm looking for

I'm looking to keep growing professionally while building high-quality web, mobile, microservices, and AI automation solutions that improve system performance and business processes.

I've built and maintained web, mobile, and backend systems at Tecnológica C.A. and MAXIA C.A., connecting responsive React and React Native interfaces with robust APIs and databases.

At Tecnológica C.A., I designed scalable microservices using Kotlin, NestJS, and Laravel Lumen, and built AWS Lambda event-driven workflows to handle background tasks and improve API communication and availability.

I've optimized complex MySQL queries, indexing, and data-access layers to reduce latency, prevent bottlenecks, and improve platform speed. I also lead maintenance, debugging, refactoring, and code-quality work that supports reliable production systems.

More recently, I've applied Generative AI, LLMs, RAG, LangChain, vector databases, and prompt engineering to automate business processes and recurring development tasks.
