## About

Principal Frontend Engineer with 14\+ years of experience building platform\-scale web applications, design systems, and frontend infrastructure across Finance, Cybersecurity, EdTech, and Travel domains\. At Arcesium, I manage and contribute to the frontend platform layer — a core component library adopted by 30\+ enterprise applications, a cross\-tab async export engine built on Shared Workers \+ AWS SNS/SQS, persisted page settings that allow creation and sharing of bookmarkable URLS, and a centralized User Preference Settings widget embedded across the entire platform\. I care deeply about developer experience, scalable architecture, and systems that teams actually enjoy building on\. What I bring to the table: → Frontend architecture & system design at platform scale → Design systems & component libraries \(React, TypeScript, Material UI\) → Browser\-native engineering \(Shared Workers, Cache API, Service Workers\) → CI/CD ownership, DX improvement, and release engineering → Team leadership, technical mentorship, and cross\-functional alignment Previously at Trellix / FireEye \(Staff Engineer\), where I led frontend development across 5 enterprise cybersecurity products — NX, EX, FX, AX, and CMS — and built internal component libraries used across product lines\. I occasionally contribute on Stack Overflow \(1,500\+ pts\) and publish CSS experiments on CodePen — because the best engineers never stop tinkering\.

## Work experience

Principal Engineer at Arcesium, Apr 2023 \- Present · 3 yrs 5 mos, At Arcesium, I led key initiatives to modernize and unify the frontend architecture across platform\-level services used by 30\+ applications\. My work focused on building scalable UIs, reusable component libraries, and intelligent workflows to support large\-scale data and reporting tools in a highly dynamic financial technology environment\. 🔹 Data Pipeline \(Aquata Suite\) – Designed and implemented the frontend for a pipeline execution platform that allows analysts to configure, manage, and trigger data transformation jobs \(SQL/Python\)\. Integrated React, Monaco Editor, and React Flow to deliver a responsive, state\-aware interface for job status tracking \(pending, success, error\)\. 🔹 Core Component Library – Architected and led the creation of a design system built on Material UI, supporting advanced widgets like ArcDataGrid, CanonicalSearch, ComboBox, and custom theming\. Adopted by 30\+ apps, the library enforces UI consistency and accelerates development across teams\. 🔹 User Preference Settings \(UPS\) – Developed a centralized widget embedded in the global navigation bar for configuring platform\-level settings \(timezone, theme, date format\)\. Built using Web Components, MobX, and Browser APIs, with reactive preference propagation through custom hooks\. 🔹 Asynchronous Export & Notification Manager – Created an async export workflow using Shared Workers, Cache API, and short polling to enable cross\-tab report generation and retrieval\. Introduced a persistent Notification Manager in the platform bar for user\-specific activity tracking\. 🧠 Drove architecture decisions, mentored engineers, and championed scalable design practices across the frontend guild\. Stack: React, TypeScript, MobX, Material UI, Monaco, Web Components, Shared Workers, Cache API, React Flow, Storybook, DocuSaurus, Gitlab CI/CD, etc

Staff Software Engineer at Trellix, Jan 2022 \- Apr 2023 · 1 yr 4 mos, Bengaluru, Karnataka, India, In this Staff Engineer role, I led and contributed to the frontend development across FireEye’s flagship cybersecurity platforms — NX \(Network Security\), EX \(Email Security\), FX \(File Malware Analysis\), AX \(Advanced Malware Analysis\), and CMS \(Central Management System\)\. I played a dual role as an individual contributor and technical leader, guiding design strategy and mentoring junior engineers to deliver scalable and secure UI solutions for malware detection, policy configuration, and system orchestration\. Key Contributions: Designed and implemented multiple new UI modules and configuration interfaces across security appliances, enabling SOC teams to manage alert rules, traffic controls, and malware inspection settings more efficiently\. Led frontend development for the Settings section across products, ensuring robust user experiences for configuring network/email/file analysis engines, thresholds, proxy settings, and threat intelligence feeds\. Took ownership of deployment and release activities, including code reviews, CI/CD pipeline integration, and post\-deployment validation in production\-like environments to ensure secure and stable rollouts\. Mentored 3 junior engineers on frontend architecture, performance optimization, and scalable component design — improving code quality and delivery velocity across teams\. Collaborated closely with backend, QA, and product teams to drive feature alignment and uphold security standards throughout the SDLC \(Secure Development Lifecycle\)\. Achievements: Uplifted overall frontend competency by establishing code patterns, reusable components, and internal documentation used across 5\+ products\. Played a critical role in cross\-product alignment through CMS — enabling centralized management of deployment, alert aggregation, and rule enforcement across appliances\. Tech Stack: React, Redux, TypeScript, Webpack, SCSS, Jest, Storybook, Ruby on Rails, MUSE Design System

Senior Frontend UI Developer at FireEye, Inc\., Mar 2018 \- Dec 2021 · 3 yrs 10 mos, Bangalore, At FireEye, I led the frontend transformation of mission\-critical security products spanning Intrusion Prevention Systems \(IPS\), Email Security \(EX\), and Central Management System \(CMS\)\. I contributed to delivering secure, performant, and intuitive interfaces that empowered SOC teams to detect, visualize, and respond to advanced threats in real\-time\. Key Contributions: Modernized the IPS module UI by migrating from BackboneJS to React \+ Redux, improving load times and maintainability for the NX and CMS product suites, which help enterprises detect and block suspicious network traffic through real\-time packet inspection and threat signatures\. Built a fully interactive Security Dashboard module to visualize system health, malware activity trends, alert spikes, and detection timelines — using HighCharts and BackboneJS with a RoR backend\. Developed and scaled FireEye’s internal React component library, based on the MUSE design system, enabling cross\-team reusability and consistent UX across multiple products\. Designed the Rule Management module for the EX \(Email Security\) suite, allowing analysts to define, prioritize, and manage email filtering rules — similar in principle to AWS Security Groups — for whitelisting, blacklisting, and isolating potentially malicious emails based on sender/domain/IP, reputation scores, or malware signatures\. Achievements: Successfully launched the new IPS interface to General Availability \(GA\) — a long\-awaited enhancement praised by both customers and engineering leadership\. Improved dashboard and IPS page performance through Webpack optimizations and modular refactors, reducing initial load time and bundle size\. Recognized by management for owning critical feature delivery under aggressive timelines with zero regression and clean QA sign\-off\. Tech Stack: React \(Hooks\), Redux \(Thunk\), TypeScript, Webpack, SCSS, Jest, BackboneJS, HighCharts, Storybook, Ruby on Rails, MUSE Design System, HTML5, CSS3, Web Components, Jenkins, etc\.
