About this gig

I design and build reliable backend systems and REST APIs using Node.js, Python, and Java. With 18+ years of experience in software architecture and SRE for critical platforms, I focus on clean code, secure authentication, database design, and scalable architecture.


What I can help you with:

- REST API design and development

- Database integration (PostgreSQL, MongoDB, Redis, Oracle)

- Authentication and authorization (JWT, OAuth2)

- Microservices architecture

- Third-party API integrations

- Code documentation and testing


I have hands-on experience implementing secure, production-grade platforms including GitLab with LDAP, CI/CD pipelines, and modernizing monolithic systems into modular REST APIs. Let's build something reliable together.
