Progressive trajectory leading high-stakes UI engineering initiatives, mentoring teams, and collaborating with global product leaders.
Cognizant Technology Solutions
Sr. Associate — Frontend Web DevelopmentSpearheading frontend development for a prominent US Healthcare product client portal. Directed Mapbox real-time tracking integrations, architected resilient API interfaces, and enforced stringent WCAG accessibility compliance alongside responsive rendering optimizations.
- Architected component architecture using modern patterns.
- Integrated Mapbox GL SDK with geolocation tracking for healthcare access.
- Conducted thorough cross-browser testing and responsive profiling across desktop, iOS Safari, and Android webviews.
- Mentored junior/mid-level UI developers in strict code quality, PR reviews, and modular component design.
Mindtree
Technical Lead – Frontend Web DevelopmentDrove high-impact multi-brand web performance optimization for Procter & Gamble (P&G), Avis Budget Group, and Intellect's proprietary Canvas Technology banking UI framework.
- Audited and radically improved Web Vitals (FCP, LCP, CLS) using CrUX, PageSpeed Insights, and GTmetrix for global P&G brand portfolios
- Collaborated directly with client product managers and design leads to turn complex specs into high-fidelity UI.
- Enforced component-driven development workflows and standardized CSS naming conventions (BEM/BEMIT).
- Led sprint estimations, task delegation, code refactoring, and sprint demos for global enterprise clients.
Intellect Design Arena
Frontend Developer & UI ConsultantLed frontend engineering squads and provided deep technical consulting for digital transformations. Established scalable reusable component modules, instituted frontend governance standards, and reduced delivery turnaround.
- Created 50+ enterprise reusable UI components (data grids, modal windows, virtual lists, form suites).
- Developed complex multi-tenant Corporate Banking Exchange (CBX) screens with fluid layouts.
SMABES Solutions
Frontend DeveloperPioneered custom responsive CSS layouts without external bulky frameworks, optimized DOM tree rendering, produced functional interactive wireframes, and ensured cross-browser compatibility across legacy and modern browser engines.
Client Engagements & Enterprise Projects
Deep-dive into flagship production solutions across global healthcare, CPG brands, fintech banking, and logistics.
US Healthcare Portal & Tracking Engine
Engineered the primary responsive patient & clinician product portal featuring live location mapping via Mapbox GL SDK, asynchronous patient record processing, and strict WCAG accessibility compliance.
Procter & Gamble Performance Optimization
Led systematic Core Web Vitals remediation across multiple global P&G brand properties. Eliminated heavy layout shifts (CLS < 0.05), deferred third-party blocking scripts, and implemented modern image/asset pipelines.
Avis Budget Group UI Platform
Created interactive prototype modules, booking flow UI engines, and cross-device vehicle reservation widgets. Built robust interactive mockups validating user flows before production rollout.
TBS Component Framework (50+ Reusable Primitives)
Architected and codified an internal enterprise component library comprising over 50 highly customizable, accessible UI primitives: virtualized data grids, nested menus, modal window managers, and dynamic form builders.
CBX (Corporate Banking Exchange) Suite
Developed institutional corporate banking interface modules handling bulk corporate transactions, multi-currency liquidity dashboards, trade finance workflows, and customer onboarding security screens.
Universal Cross-Browser & Device Architecture
Over a decade mastering cross-browser quirks, rendering engine behaviors (Blink, WebKit, Gecko), memory leak diagnostics in long-running single-page applications, and hardware-accelerated CSS rendering.
Engineered for enterprise scale, speed, and strict WCAG parity.
Core Web Vitals Obsession
Sub-2.5s Largest Contentful Paint (LCP), minimal Cumulative Layout Shift (<0.05), and sub-200ms Interaction to Next Paint (INP) across real-user monitoring data.
Design System Modularity
Authoring decoupled design tokens, semantic variables, and composable headless primitives so large distributed engineering teams build synchronously without design drift.
Cross-Browser & Accessibility Conformance
Rigorous keyboard focus traps, screen-reader landmark hierarchies, color contrast compliance, and verified DOM execution on WebKit, Blink, and Gecko.
