# Haotian Q. > Backend Software Engineer | Ex-Amazon | AWS, Micro-services & Infrastructure as Code | UIUC, UCSD Alum Location: San Francisco Bay Area, United States Profile: https://flows.cv/haotian Please email: heisenberg0711@proton.me for opportunities (Need Sponsorship). I am a backend software engineer with a unique blend of big tech and fintech experience. Currently working in the fintech sector (Treasury Management), I specialize in architecting resilient, high-availability microservices from the ground up. My technical expertise lies in Java, Python, AWS, and infrastructure as code, enabling me to build scalable systems designed for reliability and efficiency. At Amazon, I worked in Amazon's Physical Stores organization, where my team owned a critical service that manages the metadata of merchandise sold in Amazon’s physical stores (like Whole Foods), powering Amazon’s Just Walk Out technology. Later, I made significant contributions to two impactful projects. As part of Amazon Advertising, I helped launch Amazon’s first supply-side platform, a groundbreaking solution that continues to generate millions in revenue annually. This platform supports ad serving in Prime Video and Freevee. I am passionate about applying CI/CD best practices and automated testing to maintain code quality and enable seamless deployments. My focus on resilient design and infrastructure as code ensures that the solutions I build are not just scalable but also highly reliable. ## Work Experience ### Software Engineer @ Interactive Brokers Jan 2023 – Jan 2025 | Greenwich, Connecticut, United States Treasury Management ### Software Development Engineer @ Amazon Jan 2022 – Jan 2023 | Seattle, Washington, United States Building advertising supply side platform (SSP) for Amazon publisher technology: https://advertising.amazon.com/library/guides/supply-side-platform ### Software Development Engineer @ Amazon Jan 2021 – Jan 2022 | Seattle, Washington, United States Physical Stores Assortment Tech: Go, Fresh, Whole Foods Market, Books, 4-stars ### Software Engineer Intern @ XCOM Labs Jan 2020 – Jan 2020 | San Diego, California, United States Worked in System Integration and Test (SI&T) team with 8 team members to develop a Web-Based Automation Tool running on both Windows and Linux platforms used for 5G wireless system testing and customization. ### Undergraduate Research Assistant @ University of Illinois at Urbana-Champaign Jan 2017 – Jan 2019 Worked with Prof. Leonardo Chammoro and Yaqing Jin on a novel wind farm design that can harvest energy from simple flat plates. ### Undergraduate Research Assistant @ University of Illinois at Urbana-Champaign Jan 2016 – Jan 2019 | Urbana-Champaign, Illinois Area I worked with Prof. Mattia Gazzola and Levi Dudte from Harvard University on expandable 2D origami structures. ### ME 320 Heat Transfer Grader @ University of Illinois at Urbana-Champaign Jan 2017 – Jan 2018 | Urbana-Champaign, Illinois Area Grading weekly homework for heat transfer lecture (ME 320), under the supervision of Prof. Kyle Smith and Prof. Sanjiv Sinha ### Research Intern @ Technische Universität Darmstadt Jan 2017 – Jan 2017 | Darmstadt Area, Germany Developed an active vibration control system for a scaled gearbox to be used on Rolls-Royce BR-710 engine.
