About this Gig
I design and build backend APIs that stay fast and cheap as you grow.
At my day job I architected the serverless API behind a 35+ store US restaurant chain: 40-50K orders a month, sub-second p90 latency, ~99% test coverage, and around $400 a month per environment on AWS.
WHAT I CAN BUILD FOR YOU
- REST APIs in TypeScript (Hono, Express, Node.js)
- AWS serverless: Lambda, API Gateway, SQS, SNS, SES, EventBridge
- Authentication with AWS Cognito, OTP or JWT, plus role-based access
- Webhooks and background jobs on queues
- Payment and delivery integrations (Square, DoorDash)
- Infrastructure as code with Terraform: dev, staging and prod
- Tests with Vitest, plus logging and monitoring
YOU RECEIVE
- Source code in your repo, with tests
- Terraform or deploy scripts, so you own your infrastructure
- API docs (OpenAPI or Postman collection)
- A walkthrough of how everything fits together
Already have a backend that is slow, costly or fragile? I also review and fix existing APIs.

FAQ
Do I own the code?
Yes. Everything goes into your GitHub repo and is fully yours once the order is complete, including the Terraform and deploy scripts.
Which time zone are you in?
IST (India). I overlap with US mornings and evenings and the full European work day, and I reply to messages within a few hours.
What do you need to get started?
A short description of what the API should do, any existing docs or designs, and access to your repo or cloud account. I'll guide you through giving safe, limited access.
Can you work on my existing backend?
Yes. Share read access to your repo and I'll review it before quoting. I can fix slow endpoints, cut AWS costs, add tests and clean up messy code.
Do you only work with AWS?
AWS serverless is my specialty, but I also build on Cloudflare Workers and regular Node.js servers. Tell me your setup and budget and I'll suggest what fits.
