Node.js & TypeScript Backend Development
Expertise in building high-performance, production-grade APIs and scalable backend systems using Node.js and TypeScript, with a strong focus on reliability and system efficiency.
Cloud Architecture (AWS)
Proficiency in designing and deploying serverless and cloud-native architectures using AWS services including Lambda, API Gateway, S3, EventBridge, SQS, and SNS, as well as Azure Databricks.
Microservices & Event-Driven Architecture
Deep knowledge in designing distributed microservices and event-driven systems with REST APIs, ensuring high availability, fault tolerance, and scalability across enterprise environments.
Database Management
Hands-on experience with MongoDB, MySQL, and DynamoDB for designing scalable and secure data storage solutions in enterprise-grade applications.
Caching & Messaging
Practical application of Redis for caching strategies to reduce response latency, combined with event-driven workflows using SQS and SNS for asynchronous processing.
Security
Implementation of secure authentication and authorization mechanisms using OAuth2, JWT, IAM, and HTTPS, including role-based access control (RBAC) for financial and enterprise platforms.
DevOps & CI/CD
Setup and management of CI/CD pipelines using Jenkins and GitHub Actions, along with containerization using Docker to improve deployment efficiency and release cycles.
Testing
Application of Jest for unit and integration testing to ensure code quality and reliability in production-grade backend systems.
ERP & Data Analytics
Design of enterprise ERP architectures and data analytics platforms using Python and Azure Databricks, replacing costly third-party tools with custom in-house solutions.
