   Wavebreak Media

   Sep 2020 - Aug 2022

   Artificial Intelligence Engineer

   I proposed, planned, and built an Automated Keyword Generation application, which significantly decreased asset production costs. Similarly, I was instrumental in creating an application that efficiently generates similar assets from a given asset, enhancing our production capacity tenfold and facilitating the discovery of underutilized assets. Moreover, I delivered an application for dynamic article generation on various subjects, using advanced NLP technologies such as transformer-based Open Domain Q&A and language generators (GPT3, GPT-J). In another notable achievement, I developed an application that tags models in an image automatically, reducing manual effort with the help of pre-trained Face detector/Identifier ML models. My responsibilities extended beyond technical development to identifying organizational pain points and uncovering AI opportunities by engaging with internal stakeholders. I worked closely with team members and an Academic supervisor to transfer research technologies for adoption, and actively participated in building Proof of Concepts to increase operational efficiency. In the product development lifecycle, I played a key role in setting vision, defining scope, proposing solutions, and building roadmaps. I shared product strategies with the team, elucidating how they align with business goals. My duties also included creating resilient and scalable software solutions, keeping track of performance metrics, preparing quarterly reports, and effectively communicating project status and developments to stakeholders. I also facilitated the adoption of cutting-edge advancements in Machine Learning and software development techniques, thus streamlining the development and deployment lifecycle of applications. In all of my tasks, I aimed to enhance the user experience, improve operational efficacy, and align with the strategic business goals of the company.
