Cloud Engineering
Hi, I'm Dhruv.
Mechanical engineer turned cloud builder — a year of deep AWS study and a stack of things I've actually deployed.

About
I have a B.S. and M.S. in Mechanical Engineering from Stony Brook University (GPA 3.94), then spent several years leading a multi-site retail business in Georgia — hiring and training staff, running full-scope renovations, and growing one location to six-figure monthly sales before a $2.4M sale. A different world from cloud, but both taught me to reason about systems under real constraints.
About a year ago I committed to a switch into cloud engineering. Since then I've earned four AWS certifications, joined the year-long Amazon Cloud Institute developer program and the BeSA Bedrock AgentCore cohort, and built and deployed the projects below — this site included, hosted on AWS Amplify with Route 53 DNS.

Application Migration to AWS (MGN)
Rehosted a running Linux web server into AWS with Application Migration Service — continuous block-level replication, a validated test launch, and cutover to production in under 25 minutes, reconnected to its database on RDS.
Serverless · deployed
Serverless CRUD API
One Python Lambda handles create, read, update, delete and list against DynamoDB, exposed over HTTPS through API Gateway. Ships with a CloudFormation template that stands up the whole stack in one deploy.
EC2 · Docker · deployed
Production Automation Server on AWS
n8n running in Docker on a free-tier EC2 instance, served over HTTPS at n8n.builtbydhruv.com — Caddy handles TLS via Let's Encrypt, Route 53 DNS, and a nightly S3 backup script with a documented 24-hour RPO and 15-minute RTO.
S3 + CloudFront · deployed
Résumé on S3 + CloudFront
A static HTML/CSS résumé hosted on S3, served over HTTPS through a CloudFront distribution for TLS and CDN performance. CloudFormation template included.

In the works
Customer Onboarding App
In progressCapstone: an event-driven identity-verification backend for a bank. Rekognition compares a selfie against a driver's license photo at an 80% similarity threshold, Textract cross-checks 8 license fields against the application, and DynamoDB auto-scales 2–20 capacity units at 70% utilization. Next: splitting it into async Lambdas orchestrated with Step Functions.
