• Used React to develop an application which mirrors the functionality of the Chrome Developer Tools Styles tab but displays source file names and line numbers for all types of css styles, enabling faster css debugging and development.• Integrated DOM and CSS domains of Chrome Developer Protocol utilizing direct, low-level access to Chrome Browser to fetch CSS properties data of the target application, and integrated the data within the Styles Editor interface.• Implemented Redux Toolkit, using Immer and Redux thunks to simplify state management across multiple React components, handle asynchronous HTTP and API requests, ensure immutable state update and efficient data flow.• Developed a custom hierarchy of css short/longhand properties and algorithms to implement overwriting of styles by styles with higher specificity or by css cascading rules, enabling accurate rendering of DOM styles as active/crossed-out.• Utilized native CSS to style the application UI keeping the familiar look of Chrome Developer Tools to ensure seamless transition for the user to the new interface and enabling faster UI update without the overhead of compiling steps.• Built application with Vite for scalability, maintainability and faster development and load times by leveraging Hot Module Replacement, native ES modules, ES6+ transpilation, and minification to decrease the size of production builds.• Product developed under tech accelerator OS Labs (opensourcelabs.io)

• Created reusable React components for user authentication process, with conditional rendering based on built-in state, efficiently managing transitions between signup/login steps, reducing code redundancy and simplifying maintenance.• Improved data retrieval efficiency by refactoring React frontend and Node Express backend code to implement SQL queries which fetch data by an individual user, reducing unnecessary data loading and improving response times.

• Utilized React Router to enable seamless user experience of navigating between questionnaires and assessment results pages, optimizing rendering performance with minimal network requests in the Single Page Application.• Implemented PostgreSQL database to store questionnaires as relational data enabling strict ACID compliant schemas.• Developed a robust Node.js/Express server using middleware, routers, and controllers pattern to manage concurrent HTTP and API requests to the database, modularize backend processes, and ensure rapid and reliable data processing.

• Led a team of engineers to design company-wide Azure cloud infrastructure to transition from on-premise data centers to the cloud, enabling simplified system architecture and cost reductions from retiring legacy end-of-life applications.• Launched social listening centers in 2 Asia Pacific markets by implementing SaaS platform Sprinklr, leading to improved customer experience, reduction of care agent costs, and effective prevention of brand crisis.• Developed a business case for implementation of SaaS management platform at 3000 retail stores and identify opportunities to maximize project ROI reducing capital and running costs.• Defined scope and deliverables, developed project charter, communications plan, schedule and work breakdown structure, identified dependencies on other work streams and stakeholders, managed project resources and budget allocation.• Partnered cross functionally with IT Operations, Site Operations, Supply Chain Management, Finance, Reporting and external vendors.

• Led a team to integrate AR/VR experiences into service offering for enterprise clients, set up Digital Lab and created functional specs for client-facing AR assisted assembly demos using AR glasses, generating $1M/year in revenue.• Launched a database software "TechHarbor" which aggregates and visualizes startup data from global databases (Crunchbase etc.), generating $4.5M/year in revenue and user growth from 4 to 50+ in the first year.About TechHarbor: https://www2.deloitte.com/jp/en/pages/strategy/solutions/cbs/drive-open-innovation.html

• Enabled strategic decisions in R&D and new market entry for top management teams in 6 Fortune 500 and Nikkei 225 companies in manufacturing, advertising, entertainment and energy industries.• Aggregated global startup investment data from multiple databases, perform data cleaning and analyze long-term technology trends in Virtual Reality, advertising tech and clean tech.

• Automated manual reporting operations with the Oracle OBIEE, simplifying organization-wide reporting processes.• Used SQL to query operational data and test accuracy of financial, operational and management reports in the newly implemented reporting system. • Gathered client requirements through stakeholder interviews and data collection and analysis, perform fit/gap analysis, develop functional specifications. • Coordinated communication between functional, technical teams and leadership in US, UK, Germany, India, and Japan.
