As a Software Development Engineer at Amazon, 𝗜 𝗯𝘂𝗶𝗹𝗱 𝗽𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻-𝗴𝗿𝗮𝗱𝗲 𝗔𝗴𝗲𝗻𝘁𝗶𝗰 𝗔𝗜 𝗮𝗻𝗱 𝗟𝗟𝗠 𝘀𝘆𝘀𝘁𝗲𝗺𝘀 𝗮𝘁 𝘀𝗰𝗮𝗹𝗲. I apply distributed systems rigor to multi-agent architectures and LLM-driven features. My work sits at the intersection of 𝗰𝗼𝗻𝘃𝗲𝗿𝘀𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗔𝗜, 𝗮𝗴𝗲𝗻𝘁𝗶𝗰 𝗮𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻, 𝗮𝗻𝗱 𝗿𝗲𝗹𝗶𝗮𝗯𝗹𝗲 𝘀𝘆𝘀𝘁𝗲𝗺 𝗱𝗲𝘀𝗶𝗴𝗻—building pipelines that are accurate, observable, and production-ready.

𝗥𝗲𝗰𝗲𝗻𝘁 𝗪𝗼𝗿𝗸 𝗮𝗻𝗱 𝗠𝗼𝗺𝗲𝗻𝘁𝘂𝗺
Over the past few months, I’ve expanded my impact beyond my core role by designing agentic workflows, experimenting with multi-agent automation, and participating in multiple AI hackathons—where my team has been both winners and finalists.
I also mentor engineers and students on system design, technical clarity, interview storytelling, and communication. This has grown into a small but active learning community focused on practical AI, hands-on projects, and career growth.

▸ Architected prompt engineering and model optimization strategies that increased feature accuracy from ~4% to 94.78% and reduced latency by 650ms
▸ Designed state machines, lineage tracking, and failure pattern analysis for complex multi-turn LLM interactions
▸ Actively building and experimenting with multi-agent workflows beyond my core role

𝗕𝗮𝗰𝗸𝗴𝗿𝗼𝘂𝗻𝗱
I have 8+ years of experience across conversational AI, distributed backend systems, and enterprise engineering. Before Amazon, I spent 6+ years building ERP systems, full-stack solutions, and automation in agile environments. I hold a Master’s in Computer Science Engineering and am an AWS Certified Cloud Practitioner.
