About

As a passionate and performance-driven Software Engineer, I bring hands-on experience in designing and building scalable backend systems and high-throughput data pipelines. I've led the development of mission-critical applications across domains like AI-based Counter-Terrorism and Healthcare Provider Systems. In my current role, I architect and maintain real-time data pipelines using Logstash and Elasticsearch, capable of handling traffic up to 100 Gbps. I also work extensively with Java to process and compare structured provider data, automate validations, and generate insightful Excel reports for data integrity across legacy and modern systems. Beyond coding, I actively contribute to onboarding and mentoring new team members through structured knowledge transfer sessions, ensuring team continuity and project excellence. Core Skills: ✔ Java Backend Development ✔ Data Pipeline Engineering (Logstash → Elasticsearch) ✔ High-Speed Data Processing (100 Gbps+) ✔ Data Validation & Migration ✔ Excel Automation & Reporting ✔ KT & Team Mentoring ✔ Client Deployment & Production Support I’m always eager to take on challenging problems, optimize systems for performance, and collaborate across teams to deliver impactful solutions.
