Michael Batista

I’m a Senior Software Engineer with 10 years of experience building full-stack and AI/ML systems for scalable, consumer-facing applications. I focus on end-to-end delivery across frontend, backend, search, and real-time ML infrastructure.

At Uber (04/2022 - Present), I architected large-scale discovery systems for the Uber Eats Discovery Platform, combining homefeed recommendations and semantic search. I also engineered real-time personalization pipelines that reduced feature freshness from 24h+ to seconds.

I design and ship production services—backend APIs using Java Spring Boot with REST/gRPC—and deliver end-to-end features across React-based frontend surfaces, backend microservices, and data pipelines. I optimize ML inference workflows with PyTorch, ONNX, TensorRT, and vLLM, eliminating cold-start delays from 1060 seconds to near-zero.

Previously at the Royal Bank of Canada (09/2018 - 04/2022), I built AI-driven personal banking features that transformed transaction data into proactive insights for up to 1.5M users. I’ve also delivered mobile-first fintech onboarding systems at Wealthsimple (11/2016 - 09/2018), partnering with product and compliance teams to balance user experience and regulatory requirements.
