Senior/Lead Full-stack JavaScript Developer React | Node | AWS | GCP

8+ years in software development, with a focus on backend solutions and database integrations. 7+ years dedicated to mastering Node.js development, setting up, and optimizing backend architectures for high availability, scalability, and resilience. Expertise in database design, development, and administration spans a broad spectrum: from relational databases like MySQL and PostgreSQL to NoSQL solutions like MongoDB and Firebase. Proficient in optimizing database queries, ensuring data integrity, and designing fail-safe replication and backup strategies. Familiarity with AWS services like RDS, Lambda, EC2, and S3, leveraging their capabilities to build cloud-native, high-performance applications. In the realm of front-end, I have a significant track record with frameworks like Angular and React, but my forte lies in backend development where the real magic of data processing and business logic happens. My experience isn’t confined to just traditional web services. I've dabbled in the intriguing world of blockchain, exploring its potential in decentralization, smart contracts, and data immutability, and envisioning its use cases beyond cryptocurrencies. Adept in the complete Software Development Life Cycle (SDLC), from initial requirement gathering and system design to deployment and maintenance. An evangelist for best practices, especially in continuous integration, continuous deployment (CI/CD), microservices architecture, and containerization with tools like Docker and Kubernetes. Regularly interfaces with project teams, offering both technical direction and hands-on code contributions. I consistently provide critical project status updates to stakeholders, ensuring transparency and alignment. An analytical thinker, always up for a challenge, and perpetually driven by the desire to innovate and optimize in the dynamic landscape of backend development.
