March 1, 2024 - September 17, 2025Integrated voice synthesis technologies (Amazon Polly, Google, Azure, ElevenLabs) into an AWS Lambda prompt-to-video generator, enhancing the UI for selecting voice actors, emotions, and previews and upgrading the product from music slideshows to videos with voice-overs, boosting conversion rates and customer satisfaction. Led a 4-person team to implement a data ingestion system migrating a legacy Node.js platform to a modern TypeScript stack; the solution synchronized CSV data from FTP/cron workflows into dual MySQL databases via RabbitMQ, improving maintainability and robustness and halving deployment times. Evaluated a legacy e-commerce platform (Node.js, MongoDB, React) and built internal tools—a CLI using TypeScript, Commander.js, and Bash—while deploying a mirrored AWS environment with Terraform and GitHub Actions, enabling safe, rapid iterations without impacting the live stack.
