At Tata Consultancy Services, I work as a Senior Android Engineer on contract. I’ve also completed leadership and management training and coursework in LLMs, generative AI, and transformers.

At Globant, for The Walt Disney Company, I was lead Android developer on the Disney Parks ticketing app and delivered 100% of the committed scope ahead of schedule. I also worked on ESPN Fantasy Football and Tournament Challenge using Kotlin, MVI, RxJava, and Jetpack Compose, with 100% test coverage.

On Vision, an internal analytics SDK, I reduced the SDK size by 40% through dependency optimization and raised test coverage from 15% to 60% with JUnit. I also created an MVI sample app for Android TV.

Earlier, I built Android apps and services at HyphaMetrics and ADFi Mobile Marketing Studio, including Bluetooth Low Energy proximity services and JSON APIs in PHP. My work has also included data analysis and reporting at SAT, AGAFF, and web GIS development at CentroGeo.
