About

I’m a Software Engineer with 3+ years at Kickdrum, building scalable, high-performance systems across full-stack and AI-driven platforms. I’ve led teams to design and deliver production-grade GenAI solutions, including RAG-based pipelines processing 3TB+ of unstructured data, reducing information retrieval time by 96%. My experience spans React, TypeScript, Spring Boot, Node.js, and AWS, where I’ve architected cloud-native systems using EC2, Lambda, S3, OpenSearch, and QuickSight. I’ve optimized complex PostgreSQL workloads - cutting query execution time by 75% across datasets with 1M+ records. I enjoy solving hard engineering problems - from designing fault-tolerant event processing systems to building AI-powered automation that reduced manual workflows by 90%+. Beyond code, I actively mentor engineers, drive clean architecture practices, and take ownership from system design to production delivery. I’m looking for opportunities to apply my technical leadership, GenAI experience, and AWS expertise to build intelligent systems that scale and deliver measurable business impact.
