Project details
Project Description
Build Secure & Scalable REST APIs with Node.js, PostgreSQL, or DynamoDB
Looking to launch your product or automate internal workflows with reliable backend APIs?
I’ll help you build fast, scalable, and production-ready REST APIs using Node.js (Express) along with PostgreSQL or DynamoDB, depending on your data needs.
This project is ideal for:
MVPs and startup backend scaffolding
Wallet, KYC, or payment flows
Admin dashboards or internal tools
Feature flag/configuration management systems
You’ll get:
Clean and modular API code
Secure authentication (JWT, token-based)
Well-structured database schema (relational or NoSQL)
Swagger/OpenAPI documentation
Optional CI/CD, Docker, and AWS deployment
Whether you’re building from scratch or scaling an existing backend, I can deliver a stable foundation that’s easy to maintain and ready to grow.

Software Architect and Web Developer
Jaipur, India - 9:06 pm local time
I specialize in Node.js (Express, Nest.js) with PostgreSQL, DynamoDB, and deep integration into the AWS ecosystem. From complex API systems and CI/CD pipelines to AI-powered backend logic, I deliver production-ready, secure, and maintainable backend infrastructure.
Projects Delivered:
* Wallet & Transaction System Designed multi-bucket wallet architecture with reconciliation logic, fraud checks, and event-based updates using DynamoDB Streams + AWS Lambda.
* KYC & Auth Microservices Built secure onboarding flows with OTP-based login, RBAC, rate limiting, and third-party integrations. Managed secrets via AWS Parameter Store and implemented secure token issuance and expiry flows.
* CI/CD Pipelines & Cloud Deployments Set up GitHub Actions pipelines for build, test, Docker packaging, and auto-deployment to AWS ECS Fargate with environment segregation, version tagging, and rollback strategies.
* Cloud Networking & Security Designed VPC setups with private subnets, NAT gateways, security groups, route tables, and IAM policies. Enforced best practices like HTTPS-only APIs, input sanitization, and IAM least-privilege access.
* AI Chatbots & Pretrained Model Integrations Developed AI-powered bots using Gemini, OpenAI, and Ollama (LLaMA, Mistral, Code LLMs). Built endpoints for text processing, prompt chaining, and served models through API Gateway + Lambda for cost-efficient inference.
* Feature Flag Systems & Admin Tools Created internal tools for business configuration (feature flags, A/B tests) with real-time control, audit logs, and scoped access based on user roles.
Tech Stack Expertise:
* Languages: JavaScript, TypeScript
* Backend: Node.js, Express, NestJS
* Databases: PostgreSQL, DynamoDB, Redis
* DevOps: Docker, GitHub Actions, PM2, AWS ECS, Lambda, S3
* Infra & Security: VPC, NAT, Load Balancer, Secrets Manager, IAM, CloudWatch
* AI/ML: OpenAI API, Gemini API, Ollama (local inference), LangChain
* Tools: Swagger/OpenAPI, Postman, Git, Jira, Notion
What Sets Me Apart:
* 9+ years of deep industry experience, including production-critical systems
* End-to-end delivery: from planning to deployment and monitoring
* Strong foundation in security, scalability, and automation
* Hands-on with modern AI integration into backend workflows
* Fast, reliable, and committed to clean, maintainable code
Let’s build something scalable, secure, and smart — I’m ready when you are.
