As one of the four founding engineers of the Google Travel Transit team, I played a pivotal role in creating a new vertical in the travel space. Operating with a startup ethos within Google, our team rapidly developed and launched a service enabling Google Pay users (and later Google Search users) to search and book train tickets in India. ▶ Successfully established a new vertical within Google Travel in less than a year, leading to the most popular micro-app within Google Pay in India and helping 100M+ users to book the best trains.▶ Architected and delivered a highly-robust booking and search engine, processing 300K+ ticket purchases per month while providing low-latency (<50ms) access to ticket fares and availability globally. ▶ Saved Google $70M per year in third-party API fees by identifying the need, and delivering an ML powered distributed cache for ticket availability.▶ Contributed to 10+ tactical features, achieving a cumulated 16% increase in booking rate, positioning Google as the second online train travel agency in India.▶ Mentored 4 junior engineers who progressed to senior roles. ▶ Routinely partnered with a large group of stakeholders and leaders (Eng, PM, UX, BD, and Legal) globally distributed (Switzerland, India, Singapore, Australia, and US).

As a member and later Tech Lead of the Travel Logs team, I led the design and development of data pipelines processing hundreds of TB daily, extracting vital insights for Google Flights and Hotels. Recognized as the "go-to" person for Travel logs analysis, I was instrumental in aiding cross-functional teams to understand and enhance product performance.My key achievement was the creation of 'Travel Sessions', a comprehensive data warehouse for the Travel vertical. Travel Sessions streamlined multiple data pipelines, reducing processing costs significantly, and enabled Product Managers and UX Researchers to perform self-service analysis. This shift not only saved costs but also freed Engineering resources from performing routine analyses.

As a 20% contributor to Google Research team, I focused on integrating cutting-edge scheduling algorithms from my PhD research into Google OR-Tools. This integration not only strengthened OR-Tools' capabilities but also reinforced its position as a leading solution to tackle the world toughest problems in combinatorial optimization. Indeed, Google OR-Tools had been winning gold medals of international competitions since 2013, and my contributions played a significant role in maintaining and extending this winning streak.Specifically, I focused on lazily encoding the deductions of scheduling propagators into clauses and predicates. These are then leveraged by the SAT solver (at the core of OR-Tools' Constraint Programming solver) to strengthen its inference and learning capabilities thus significantly reducing the size of the search space to explore. Some of my other contributions include designing a property-based testing framework for various advanced filtering algorithms, and designing/implementing a new task-specific sorting algorithm that achieved ~30% speed improvement compared to the default option.

As a FRIA research scientist, I conducted fundamental research in computer science and combinatorial optimization, designing algorithms to solve NP-complete problems that were previously too large to be solved in practical time. Many of these algorithms were implemented in commercial/professional optimization tools such as Google OR-Tools or IBM CPLEX.Beyond my research work, I taught advanced computer science to classes of around 50 master's students, ensuring a comprehensive and engaging learning experience. I also played a key role in supervising Master's theses, where I guided students through complex research methodologies and helped them deepen their understanding and mastery of intricate concepts in the field.
