I’m a backend-oriented full-stack developer specializing in building secure, scalable, and maintainable web applications. My main focus is designing backend systems that handle authentication, authorization, and complex data access logic while integrating smoothly with modern frontend frameworks.

Integration with external services and APIs

Multi-Tenant & Data-Driven Systems

Tenant-aware data models (organizations, buildings, devices)

Secure isolation of user data

Integration with metadata APIs and time-series data sources

Backend logic for dashboards and monitoring systems

Cloud & Deployment

AWS (EC2, RDS, S3)

Docker-based deployments

Basic DevOps setup for small to mid-scale systems

Frontend Integration

React / Next.js integration

I work well in short, focused sprints or long-term collaborations, and I prioritize clean architecture, security, and clear communication.
