What I'm looking for

I am looking for a role that fosters innovation, collaboration, and continuous learning in a dynamic environment.

I am a Senior Full Stack Software Engineer with over 7 years of experience in delivering robust, cloud-native applications across various industries, including healthcare, logistics, fintech, and e-commerce. My expertise lies in backend development using Python (Django, Flask), Node.js (Nest.js, Express.js), C# (.NET Core, ASP.NET), and Java (Spring Boot). I am also proficient in modern front-end frameworks such as React, Next.js, Angular, Vue.js, and TypeScript.

Throughout my career, I have demonstrated a strong ability to design and maintain RESTful, FastAPI, and GraphQL APIs, as well as scalable, secure architectures following domain-driven design principles. I have successfully deployed applications to cloud platforms like AWS and GCP, managed CI/CD pipelines, and leveraged Docker and Kubernetes for container orchestration. My commitment to clean code and system performance has been recognized in Agile environments, where I have also taken on leadership roles to mentor junior engineers.
