Led the implementation of the loan application platform’s core modules, including multi-step form flow, secure authentication, and backend API. Designed and implemented a complete GA4 analytics system for the multi-step loan process (session lifecycle, step events, navigation attempts, completion, abandonment, and signing progression). Migrated backend services from Express.js to NestJS, introducing modular architecture and improving code maintainability and scalability. Implemented pagination and selective field projections to boost backend performance for large datasets. Restructured a complex multi-step loan application form into modular Angular components to improve readability and onboarding. Integrated frontend and backend unit tests into the CI pipeline with GitHub Actions, including migration of frontend tests from Karma to Jest. Integrated Sentry for error monitoring and performance tracking. Improved frontend performance and accessibility with SEO-friendly practices (Angula

Evolt Mobile App — a React Native-based fitness app. Built cross-platform features using React Native, Expo, and React Navigation. Implemented Trainer Mode, Capture Analytics, and Scan Parser. Integrated Firebase Analytics for event tracking. Built GitHub Actions pipelines to automate testing, deployment, and releases. Performed end-to-end and unit testing with Jest and Playwright. Improved app performance by 25% after introducing React Query for API caching and data fetching optimization. Refactored codebase from class components to functional components, reducing thousands of lines of code.

Developed core API features for credential issuance, credential schema, credential template, and credential requests using React, TypeScript, and RTK Query, ensuring secure credential management across a multi-tenant platform. Architected and maintained application state with Redux Toolkit and RTK Query, refactoring legacy useReducer logic for scalability. Migrated the build system from Webpack to Vite, optimizing build times. Implemented a multi-step credential issuance workflow with strict type validation using React Hook Form. Integrated React Intl for multi-language support. Implemented page-based pagination and sorting for credentials, issuance, verifications, and templates. Designed and maintained CI/CD pipelines with Bitbucket Pipelines and AWS S3 + CloudFront; containerized with Docker; instrumented with OpenTelemetry for observability.
