About this gig

Need an enterprise-grade backend? I am a Senior Software Engineer with over 20 years of experience, including 15 years as a Tech Lead at Citigroup. I build scalable, secure REST APIs using Java (Spring Boot) and Node.js (TypeScript), integrated with SQL databases. I apply Clean Code, SOLID principles and banking-grade standards so your system is maintainable and reliable. Please message me before ordering so we can scope your project.
