Software Engineer with 8+ years of experience building and scaling production applications across frontend, backend, and cloud infrastructure. Progressed from frontend development into full-stack and senior engineering roles, with hands-on expertise in Python, Node.js, Go, React, TypeScript, AWS, and GCP. Experienced designing microservices, event-driven systems, and CI/CD pipelines, with a consistent record of improving reliability, reducing latency, and shortening release cycles. Most recently focused on integrating LLM-powered capabilities, including RAG pipelines and agentic tool-calling workflows, into production applications. Approaches engineering by pairing full-stack fundamentals with an early, hands-on evaluation of emerging tools, then translating that evaluation into practical, production-ready systems.
