About

💻 About Me I’m a Software Development Engineer at Amadeus Software Labs, passionate about building scalable and reliable backend systems. My expertise spans Java, Python, Generative AI, LLMs, Vector Databases, and system integrations that enhance performance and customer experience. At Amadeus, I’ve contributed to Air Canada’s replatformization projects, driving initiatives like Continuous Pricing and Companion Pass, which improved dynamic fare computation and customer loyalty. I also led process optimization efforts, reducing production recurring issues by 30% and improving overall development efficiency. Additionally, I’ve built AI-driven platforms, including an LLM-powered chatbot using LangChain, OpenAI, and Python, achieving a 98% reduction in integration costs, and an AI-based dynamic page generation system that allows airlines to create websites from simple prompts using LLMs, LangSmith, React, Flask, and JWT. Beyond work, I’m deeply interested in AI-driven automation, system design, and backend optimization. I participated in global coding competitions, earning top ranks in Google HashCode, Google KickStart etc. These experiences have sharpened my problem-solving abilities and fueled my passion for innovation, driving me to push the boundaries of what’s possible with AI and software engineering.
