About this service

Summary

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.

FAQs
