Cloud Infrastructure & CI/CD
Hands-on experience with AWS (ECR, EKS), Docker, Kubernetes, Terraform, and GitHub Actions to configure CI/CD pipelines, containerization, and cloud-native deployments for high-traffic production environments.
Database Management
Proficiency with PostgreSQL and Redis for relational data storage, caching, and Pub/Sub messaging, as well as ORM tools like DrizzleORM for scalable data layer design.
Microservices & Event-Driven Architecture
Design and implementation of microservices architectures using message brokers such as RabbitMQ and BullMQ, enabling reliable event-driven processing and background job handling.
React & Next.js Frontend Development
Building customer-facing interfaces and internal tools with React, Next.js, and Tailwind CSS, delivering high-performance, responsive user experiences.
OpenAI & AI Integration
Integration of OpenAI APIs and Anthropic Claude into production systems to generate automated summaries and support AI-powered clinical documentation workflows.
GraphQL API Development
Design and implementation of GraphQL APIs to support flexible data querying across e-commerce and education platforms.
Observability & Performance Optimization
Application of monitoring tools like Datadog, along with query optimization and caching strategies, to improve performance and reliability under high-traffic conditions.
