My work spans metric design, debugging workflows, and performance sign-offs. 🔹 Led the adoption of Interaction to Next Paint (INP) as Bing’s responsiveness metric - built debugging workflows, identified major responsiveness bottlenecks, and enabled systematic monitoring and improvements at scale. 🔹 Partnered with dozens of feature teams, influencing architecture and recommending code-level optimizations to ensure every change meets Bing’s performance standards. ### Software Engineer 2 @ Microsoft Jan 2022 – Jan 2024 | Redmond, Washington, United States ⭐ Focus: Copilot and Edge New Tab (Web Performance) 🔹Identified and shipped a Chat FTR (First Token Response) improvement of 3% at P90 in the initial version of Microsoft Copilot. 🔹Implemented a performance optimization to pre-establish WebSocket connections on user intent; deprioritized before shipping due to organizational changes. 🔹Shipped Web Vitals for Edge NTP (New Tab Page) with ~95% reliability, strengthening performance monitoring and unlocking actionable insights for feature teams. 🔹Optimized Edge NTP performance by sending navigation requests before Service Worker boot and implementing a cache–network race strategy for slow devices, improving Revenue (+1.5%) and DAU (+0.5%) metrics. 🔹Identified a gap in the build system and introduced a Webpack loader that eliminated unnecessary schema config files in production, cutting 400KB of JavaScript and improving load times. ### Software Engineer 2 @ Microsoft Jan 2021 – Jan 2022 | Bengaluru, Karnataka, India ⭐ Focus: Microsoft Teams and People Experiences 🔹Upgraded the client side architecture of “People Search” component in MS Teams that improved result relevance and reduced latency by 300ms at P90. 🔹Explored MetaOS to design a POC for loading the Outlook People module in Teams, estimated effort across areas, and evaluated GraphQL-based data retrieval solutions in both apps to weigh trade-offs against reimplementation. ### Software Engineer 2 @ Microsoft Jan 2019 – Jan 2021 | Bengaluru, Karnataka, India ⭐ Focus: Outlook on Mobile (Web Performance) 🔹Drove a year-long performance initiative for Outlook Mobile Web, reducing “Outlook Mail” load time from 4.5s to 3s. 🔹Established monitoring infrastructure to track performance at scale and engineered a Service Worker, improving speed, resilience, and reliability of the mobile experience. ### Software Engineer @ Microsoft Jan 2018 – Jan 2019 | Bengaluru, Karnataka, India ⭐ Focus: Outlook Mobile PWA and Outlook Web (Desktop Calendar) 🔹Among one of the early 6 engineers on Outlook Mobile Web, I developed and stabilized the Email app for 70M+ monthly active users. 🔹I later planned and migrated core dependencies to a shared infrastructure with desktop web, driving collaboration and significant build improvements. 🔹To scale the team, I led a two-month Web Bootcamp in a team of 4 that onboarded 25 engineers and accelerated their contributions. ### Software Engineer @ Headout Jan 2016 – Jan 2017 | Bengaluru Area, India ⭐ One of the early engineers on web frontend team. established codebase foundations, rebuilt the booking flow, and built key user journeys driving conversion growth. 🔹I rebuilt the booking flow with performance, reusability, and extensibility as core principles, which drove a 23% increase in conversion rate and enabled faster experimentation and iteration. To support this, I built a scalable frontend architecture with lazy loading, reusable HOCs, and robust state management, ensuring the system could adapt and grow with business needs. 🔹In addition, I developed fully functional frontend pages and components across the customer journey, including landing, product detail, checkout, and post-booking experiences. I also resolved browser-specific issues, refactored legacy code, and optimized build processes by migrating from Webpack v1 to v3 to improve performance and reliability. As part of the Growth team, I prototyped and implemented A/B experiments that directly contributed to higher conversions. ### Software Developer @ Blinkit Jan 2016 – Jan 2016 | Bengaluru, Karnataka, India ⭐ Joined Blinkit through a Pre-Placement Offer (PPO) after a successful internship. 🔹Developed a frontend authorization framework on client side using AngularJS. 🔹Drove the adoption of ReactJS by building an in-house inventory management tool from scratch. ### Head of Student Group – UI Design & Frontend @ Information Management Group, IIT Roorkee Jan 2013 – Jan 2016 | Roorkee, Uttaranchal, India ### Software Internship @ Blinkit Jan 2015 – Jan 2015 | Gurugram, Haryana, India 🔹Designed and implemented single-page web applications from scratch using AngularJS, enhancing operational efficiency. 🔹Achieved a Pre-Placement Offer (PPO) for exceptional performance during the internship at Blinkit. ## Education ### Bachelor of Technology (BTech) in CSE Indian Institute of Technology, Roorkee Jan 2012 – Jan 2016 ## Contact & Social - LinkedIn: https://linkedin.com/in/himanshujariyal - Website: https://medium.com/@him_jar - Website: http://himanshujariyal.github.io/hjme --- Source: https://flows.cv/himanshu JSON Resume: https://flows.cv/himanshu/resume.json Last updated: 2026-03-22
