## About

```text
At Commergence, I design AWS architectures and build full-stack platforms that connect mission-critical REST and GraphQL workflows. I also use Cursor, ChatGPT, and OpenAI APIs to support AI-assisted development.

At Tachyon, I orchestrated a zero-data-loss migration of 500M+ records from Salesforce to PostgreSQL, OpenSearch, and S3 using Apache Airflow. I also contributed to an AI-augmented generation platform using LLMs, RAG, prompt orchestration, and validation pipelines.

At Deqode, I developed web and mobile applications with React.js, React Native, TypeScript, and Node.js, and built serverless microservices with Python and AWS Lambda. I also mentored engineering professionals and coordinated sprint delivery.
