At Agremo, I build ERP, e-commerce, and fintech applications using React, TypeScript, Vue, AWS, and NestJS. I improved an e-commerce project's performance and SEO by 30% through lazy loading, CDN fonts, and Next.js server-side rendering.

I've designed database architectures, built GraphQL APIs with PostgreSQL and NestJS, and delivered serverless payment functionality with AWS Lambda, S3, Keycloak, and Stripe. I also use Docker, Jest, Cypress, and GitHub Actions to support reliable deployment and automated testing.

Previously at Jobbatical, I developed healthcare web and mobile products with React and React Native, improved a Next.js e-commerce project by 25%, and built location-tracking functionality with Firebase. I contributed through code reviews, pair programming, and mentoring junior developers in a distributed team.

Earlier at ZenDev, I helped modernize JavaScript applications, migrated AngularJS to React with an ASP.NET backend, and created responsive drag-and-drop scheduling interfaces and data visualizations with D3. I enjoy solving complex problems, collaborating closely with business teams, and delivering maintainable products with user-friendly designs.
