I’m a Senior Full Stack Engineer who can take a product from idea to production. On the frontend, I build clean, fast dashboards and internal tools using React/Next.js/Angular/Vue. On the backend, I design scalable APIs and microservices - especially with Kotlin/Java (Spring Boot, GraphQL), and I also deliver with Node.js (NestJS), Go, and Python (FastAPI) when the system requires it. On the DevOps side, I deploy and operate on AWS, using Docker/Kubernetes and CI/CD pipelines, and I take responsibility for reliability and cross-service integration in production. I can start work immediately.
