What I'm looking for

I’m looking for a role where I can own end-to-end product development—building responsive UIs, secure REST APIs, and scalable cloud deployments—while collaborating closely to deliver polished, dependable user experiences.

I’m a Senior Full Stack Developer focused on building end-to-end web applications. I design interactive front-end interfaces and develop secure, scalable back-end services—leveraging React, modern JavaScript (ES6+), and modular component structures to deliver seamless user experiences.

On the back end, I build REST APIs and core application logic with Python (Django/Flask/FastAPI) and Node.js (Express/NestJS), and I manage secure PostgreSQL database schemas for authentication, identity, and role-based access control. I also incorporate AI/ML capabilities, optimize deployment with Docker and Kubernetes, and ensure reliability through comprehensive unit and integration tests (Jest, Pytest, Postman).
