I am a Senior Full Stack Engineer with over 10 years of experience building modern web applications. My core expertise is in JavaScript/TypeScript on the backend (Node.js, Express.js, Nest.js) and frontend (React.js, Next.js, Vue.js). I have deep experience with cloud platforms (AWS, GCP, Azure), containerized and cloud-native architectures (Docker, Kubernetes), and infrastructure automation (Terraform, Ansible). I’ve led projects around secure API design (REST, GraphQL), high-performance databases (MySQL, PostgreSQL, MongoDB, Redis), and real-time event-driven systems (Kafka, RabbitMQ). As a senior engineer, I excel in CI/CD pipelines (GitHub Actions, Jenkins, GitLab CI), and I enjoy integrating AI/ML solutions such as NLP and recommendation engines to enhance retention. I value continuous learning and aim to create smarter, balanced development environments that empower teams and improve productivity.
