Gorakh Chavan

Profile

Full stack developer with 5+ years of experience building MERN applications (MongoDB, Express, React, Node.js) and cloud-native systems on AWS: Lambda, API Gateway, SNS/SQS, DynamoDB and S3. I design REST APIs and microservices, data models in MongoDB and PostgreSQL, and the React front ends on top, and I've shipped AI features with Amazon Bedrock and Claude behind human-review gates. Comfortable with Agile delivery, code reviews and mentoring developers.
