I design and implement serverless backends using Java, AWS Lambda, API Gateway, and PostgreSQL.

With over 25 years of software engineering experience, I focus on data consistency, maintainability, and cost efficiency.

Every project includes clean architecture, detailed documentation, and long-term reliability for production systems.

What's included

Fully functional AWS Lambda backend

A complete Java-based backend running on AWS Lambda, integrated with API Gateway and PostgreSQL (RDS or Aurora). Includes deployment scripts, configuration files (YAML/JSON), and connection management for secure and scalable execution.

Database schema and SQL scripts

Normalized PostgreSQL database schema optimized for serverless workloads, including indexes, triggers, and example SQL queries for testing and verification.

Technical documentation and setup guide

Comprehensive documentation covering project structure, environment variables, deployment procedure, and maintenance steps. Delivered in Markdown or PDF format for easy integration into client documentation systems.

Cloud Cost Optimization Report

Short report analyzing Lambda invocation costs, RDS instance sizing, and potential improvements for scalability and efficiency.

FAQs

Yes, I can connect to any REST or SQL backend (PostgreSQL, MySQL, or cloud services).

Absolutely. I can assist with deployment on AWS Console, CLI, or CI/CD pipelines.
