Senior Software Engineer at Brevo (2023-03 – Present)

• Architected a flexible, configuration-driven UI architecture that decoupled product customization from core component logic, reducing development overhead and accelerating feature delivery across 3 product lines.
• Led adoption of a federated component library with Storybook and atomic design principles — reducing average component build time from 3 days to 2 and enabling independent frontend deployments across teams.
• Cut CI build time from ~8 min to ~5 min (37% reduction) and lifted Lighthouse performance scores by 20% via Webpack tree shaking, chunk splitting, and lazy boundary tuning.
• Maintained and scaled a centralized design system adopted across 12+ products, standardizing UI patterns and improving developer experience and cross-team consistency.
• Implemented React performance patterns including lazy loading, Suspense boundaries, and loading skeletons, delivering measurably faster perceived load times and improved Core Web Vitals (LCP, CLS, FID).
• Drove micro-frontend architecture using Module Federation, enabling autonomous team deployments within a monorepo setup.
• Delivered full internationalization (i18n) support across multiple locales, including locale date, number, and currency formatting.
• Led end-to-end migration of the entire SMS creation service (20 APIs) from PHP to Node.js and Express.js, improving code modularity, testability, and significantly reducing developer onboarding time.
• Integrated Twilio services to enable SMS functionality for marketing campaign creation and delivery workflows.

Software Engineer at To The New (2022-08 – 2023-03)

• Architected and developed a full-stack platform frontend using React, Context API, and custom Hooks; integrated Strapi headless CMS to enable non-technical teams to manage content independently.
• Designed and implemented RESTful APIs with Node.js and Express, incorporating JWT-based authentication via Passport.js, role-based access control, and centralized error handling middleware.
• Implemented Redis caching and cursor-based pagination on feed APIs, reducing database load and optimizing query performance for large datasets.
