Software Dev Engineer I

  • [PCI-DSS Payment SDK] Developed a secure, conversion-optimized payment SDK serving 2,000+ merchants processing millions of daily transactions, implementing WCAG 2.1 AA accessibility standards and adaptive UI with Vue.js across mobile, tablet, and desktop platforms.
  • [Internal Core UI Library] Architected a scalable, enterprise-grade Design Language System (DLS) UI library powered by Storybook documentation, accelerating cross-team feature delivery by 40% through highly reusable and extensible component frameworks tested with Vitest and Playwright.
  • [Payment Platform Admin Panel] Spearheaded the migration of a legacy Angular 9 database dashboard into a greenfield, high-throughput administration panel using React, TypeScript, and atomic layouts, delivering lag-free processing of millions of real-time network data points.
  • [Payouts Application] Spearheaded an application-wide migration from a legacy compilation setup to a decoupled React 19 and Vite pipeline, accelerating microservice frontend build and deployment times by 75%.
  • [Bill Payment Platform] Designed event-driven transaction pipelines using Springboot, Apache Kafka, and Oracle DB to automate real-time bill settlements and recurring mandate payments across millions of daily active nodes.
  • [BIN Data Processor - Batch Ingestion] Built a file-based CLI data ingestion engine using Java 17 and high-efficiency JDBC batching to standardize multi-network card/token metadata, using in-memory TreeSets to prevent range overlap conflicts.
  • [BIN Data Processor - Schema Thresholds] Implemented strict fail-fast pre-processing validation loops and configuration-driven schema thresholds to automatically quarantine malformed bank data rows before hitting master database layers.
  • [Distributed Observability] Integrated structured end-to-end telemetry across microservices using GitLab CI/CD, Sentry, and SonarQube analytics, reducing production runtime errors and unhandled exceptions by 35%.

  • [Browser Extension Sync] Developed a full-stack browser extension syncing background scripts with Node.js/Express backend microservices to maintain custom state machines across browser lifecycles.
  • [Image Editor Tool] Developed an in-browser layer-based photo editor using SVG and HTML5 Canvas APIs for advanced client-side image manipulation.
Fibo

Frontend Developer Intern

  • [Greenfield Platform Architecture] Authored a greenfield platform using Next.js and Zustand, taking complete ownership of state management and asset delivery configurations to minimize initial page loading performance bottlenecks.
Leegality

Frontend Developer Intern

  • [Standalone Developer SDK] Built custom standalone JavaScript plugins for embedding interactive utility widgets inside third-party internal developer dashboards.
  • [React Migration] Refactored legacy class-based React/Redux components into functional components, modernizing the codebase and establishing scalable state patterns.
