Cyber Intel pvt ltd • Full-time

Feb 2018 - Jun 2022 • 4 yrs 4 mos

As a Full Stack Engineer at Cyber Intel Pvt Ltd, I played a key role in designing, building, and maintaining high-performance threat intelligence platforms and security monitoring dashboards that process complex cyber telemetry in real time. Leveraging React.js, Next.js, and TypeScript on the frontend alongside Node.js, Python, and PostgreSQL on the backend, I built secure, interactive UI components and scalable RESTful/GraphQL APIs equipped with Elasticsearch for fast data indexing and retrieval. I spearheaded the integration of secure coding standards (OWASP), role-based access control (RBAC), and WebSocket-driven real-time data streaming to visualize attack surfaces and security analytics effectively. Collaborating closely with security researchers, I optimized end-to-end database queries, containerized microservices using Docker for CI/CD deployment on AWS, and delivered reliable, mission-critical web applications that actively defend organizations against evolving cyber threats.
