Building foundational frameworks to accelerate front end development across the organization.Initially focused on front-end performance improvements. Implemented a novel approach for front end virtualization, enabling significant performance improvements with support for components of unknown and changing size. Defined front-end performance metrics, added instrumentation, and configured monitoring dashboards in order to track performance SLOs.Additionally contributed to several AI-enabled front end workflows, directing users to existing projects aligned with their prompts or generating SQL/data-viz configurations for ad-hoc explorations based on their prompts.Involved in other efforts including candidate interviews, product on-call rotation, 3rd party library upgrades, architectural reviews and recommendations.

New York, Ny, Us

Contributed to new front end feature development, page redesign work, component library, data visualization library, and global front end platform features. This work required close collaboration with multiple feature teams, product managers, and members of the UX design team.

Sunnyvale, California, Us

Providing architectural guidance for the core front end platform (React/TypeScript).Led the effort to implement a full-featured React component library (leveraging Ant Design and other 3rd party libraries) and revamp the entire SPA to leverage the new design system.Introduced Cypress for automated end to end testing of the core user-facing application, implementing custom functions to simplify interaction with Lacework components and building reference tests to guide the team.Delivered a full-featured React query viewer/editor with syntax highlighting, code completion and validation for the custom Lacework query language.

(acquired by Juniper Networks)Architect and lead for UI/UX team, building web-based applications for managing next generation AI-enabled wireless networks.As a member of the founding team, established the front end stack composed of ReactJS, ES6, WebPack, LESS, and D3. Hired, trained and worked alongside the initial UI/UX during the foundational years to build the core network management application. In a fast-paced startup environment we rapidly delivered a highly complex application with features for configuring, monitoring, and troubleshooting WiFi and Bluetooth networks.Spent a few months away from Mist helping former colleagues build out the MVP for a startup in the identity verification space, then returned to continue my role with the Mist UI/UX team.Under the direction of the Mist CTO and co-founder, designed and implemented one of the most significant features of the Mist platform – “Marvis” a natural-language driven, AI-enabled platform for contextual search, analytics, and network troubleshooting. Evaluated NLP systems, configured and trained a DialogFlow-based NLP agent, added front-end logic to load and present the requested data, designed a corresponding structured query language (MQL), and built the UI components needed for auto-completion and validation of the MQL constructs.The innovations brought to the market by Mist led to rapid adoption and significant year over year growth, culminating in acquisition by Juniper Networks in 2019 and transformation into the “AI-Driven Enterprise” division with a vision to expand the Mist cloud, AI, and UI to encompass the entire networking stack (wireless/wired/wan).Current responsibilities include exploring new front end frameworks/libraries/tools, prototyping experimental UI features, building an updated React component library, performing significant refactoring to improve the codebase, analyzing and improving front end performance, and leading the team of 16 developers and designers.

Bloomington, Illinois, Us

Inaugural member of the Data Science team, specializing in the design and implementation of interactive web-based data visualizations.Working with a wide range of visualization technologies including D3 and SVG for basic charts, Canvas for complex custom visualizations, Leaflet.js and ArcGIS for interactive maps.Creating full stack visualizations architected as single-page JavaScript applications utilizing open source frameworks such as ReactJS, Browserify, Flux, and others. Accessing data from PostgreSQL, MS SQL Server, Hadoop, HBase or flat files via a Java-based REST API.

San Jose, California, Us

Responsible for User Experience design and development across the entire Zscaler product line.Led a re-architecture of the core UI product (client and server), building a new 4-person development team, establishing the technology stack, acting as the Product Management liaison and leading the implementation effort. The new UI is built as a single-page JavaScript web application using jQuery, Backbone.js, Handlebars.js and RequireJS with features including multiple dashboards, customizable reports and interactive analytics. The server side provides a REST API built on top of the Jersey framework.Initiated several key UI design efforts including a customizable widget-oriented reporting framework, an interactive advanced analytics page, simplified configuration of security policies and an Advanced Persistent Threat (APT) dashboard.Conducted research and implemented big data prototypes utilizing Hadoop, custom Map/Reduce jobs, AWS, and in-memory databases to investigate opportunities for deep analytics products.

(acquired by Motorola)User interface design and development for large-scale interactive applications used for monitoring and securing wireless networks. Applications developed using Java/Swing and Adobe Flex technologies.Led the transition from Java/Swing to Flex development including technology evaluation, prototyping, establishing best practices and mentoring the developers as they learned Flex and ActionScript. Implemented a Flex-based application for troubleshooting wireless connections. Created several key Flex components including an MVC framework, custom layout managers and proxy layer for wrapping server-side access (using BlazeDS to communicate with server-side Java).Designed and implemented a Java/Swing-based graphics framework for building interactive charts with multiple dimensions of. Implemented a location heat map view which shows a heat map of the location of a wireless device over a given period of time.

Participated in a small team rewriting a large-scale document processing application using the Eclipse Rich Client Platform (RCP). Developed several UI-intensive plugins including a SQL editor, database structure view, dynamic field-mapping tool and custom drag and drop framework.

Contracted at Verizon Wireless to create large-scale enterprise applications. One such application provided access to hundreds of network elements with a custom Java/Swing user interface that mimicked the corporate look and feel and a scalable Java back end that was able to handle thousands of simultaneous sessions.

Developed Java/Swing applications for managing multi-channel SONET/SDH telecom test equipment. Applications included custom UI components, distributed communications (Java/RMI and CORBA), and data visualization.

Arlington, Va, Us

Developed signal-processing applications in C++ for military and commercial applications. Held a Top Secret/SCI clearance.
