Projects Experience

• SA Engine Array Processing

  Oct, 2023 - Present

  Patent pending: 2351429-2. SA Engine includes a framework for high-performance processing of numerical models specified as queries over multi-dimensional arrays. The framework enables “low code” definition of numerical models over vectors, matrices, and tensors. Such models are central in many fields, for example, image processing, statistical models, and various kinds of AI algorithms. The framework produces highly efficient machine code on the fly that can immediately execute on engines running on resource-constrained devices.

  • Designed rewrite and optimization rules, achieving a 275% performance improvement over OpenVINO and TensorFlow Lite on single-core CPUs.

  • Implemented efficient physical storage of arrays in memory to support large-scale numerical models.

• SA Vscode plugin

  Feb, 2023 - Present

  Developed the VSCode plugin for SA Engine and Federation Services. This plugin provides real-time visualization in the notebook feature of VSCode while working with SA Engine and implements standard LSP functionalities such as autocomplete and go-to-definition for both the query language and Lisp.

• Ready4Air Core SDK Android

  Oct, 2015 - Aug, 201610 months

  When I joined the Ready4Air team at Valtech the Ready4Air core library didn’t exist. Shortly after I decided together with the lead Android developer that we should extract the media playback features into a separate Android library allowing us to reuse code between applications. The first version was a pure extraction of classes into an separate android library. Due to low testability of the original code I started developing version 2.0 of the core library while also working on SF kids. Version 2.0 is completely remade from scratch implementing the same clean architecture as in SF kids in order to increase testability and taking future extension into close consideration.
