About this gig

Need a backend API that scales automatically without managing 

servers? I build production-ready serverless REST APIs with 

Node.js + TypeScript on AWS Lambda.


2+ years building serverless backends for a US fintech startup. 

I know what breaks in production and build to avoid it.


WHAT I BUILD:

-CRUD APIs for web or mobile apps

-Webhook handlers (Stripe, Twilio, WhatsApp, etc.)

-User authentication (JWT or AWS Cognito)

-Background jobs with SQS queues

-File upload/download with S3 presigned URLs

-Third-party API integrations


TECH STACK:

Node.js + TypeScript · AWS Lambda · API Gateway · DynamoDB · SQS · Cognito · Serverless Framework


EVERY DELIVERY INCLUDES:

-Clean TypeScript code with comments

-README with setup and deployment instructions

-No hardcoded secrets env variables only

-Deployed and tested in your AWS account

I am a Backend Engineer with 2+ years of experience building cloud-native apps for US startups. I specialize in Node.js, TypeScript, and AWS Serverless architectures. I write production-grade code, not no-code bots. I optimize backend latency, provision infrastructure using Terraform, and integrate advanced AI. I also built Tavia, an AI receptionist that handles restaurant reservations over WhatsApp using GPT-4o — with smart table assignment and automated reminders. Stack: Node.js, AWS (Lambda, API Gateway, DynamoDB), Terraform, OpenAI API. Message me your requirements.
