Work Experience

Associate Consultant - Fullstack Developer

GlobalLogic

Nov 2023 - Present

Led migration of a legacy energy-domain application to a config-driven React, TypeScript, and GraphQL platform, improving maintainability through reusable workflows, widgets, charts, and Mapbox visualizations. Built enterprise workflows using React, TypeScript, HTML, CSS, and Express.js, extending reusable configurations to support diverse energy analytics use cases without duplicating application logic. Owned weekly AWS ETL workflows across Lambda, Glue, Step Functions, and SNS, implementing Teams failure alerts via webhooks to accelerate issue detection and ensure timely data refreshes. Fixed a Step Functions rerun issue that caused data duplication after failed ETL executions, eliminating manual cleanup and reducing delays to the 8-hour weekly data refresh process. Engineered AWS CloudWatch dashboards and Synthetics monitoring for service health and critical user journeys, improving production observability and enabling faster detection of application issues. Reduced AWS OpenSearch costs by approximately 40% through query optimization and infrastructure tuning, lowering cloud spend while maintaining application functionality.

Frontend Developer

MiM-Essay

Apr 2022 - Oct 2023

Led frontend development for an early-stage study-abroad platform, building API-driven features with React, Next.js, and REST APIs that enabled students to evaluate schools based on their qualifications and eligibility. Built a multi-step school recommendation flow that matched student qualifications against relevant schools and presented detailed eligibility breakdowns, improving the platform’s ability to guide students toward suitable study-abroad options. Optimized SEO-critical Next.js pages to achieve 85+ Google PageSpeed scores, reducing JavaScript payload through code splitting and replacing heavy dependencies to improve page load performance. Led and mentored two frontend developers, establishing consistent implementation practices and improving coordination and quality across feature delivery in an early-stage startup environment. Refactored a significant portion of the React codebase into maintainable, reusable modules, reducing code duplication and simplifying future feature development while establishing greater consistency across the frontend.
