I have worked on high-scale products, including microservices serving millions of users, platform migrations with zero downtime, and backend systems that support complex business operations. I enjoy owning features end to end, from technical design and implementation to testing, release, and documentation. I also like improving team workflows through automation, AI-assisted development, and clearer engineering processes. I founded MarbleOX, an AI-powered ERP and quoting SaaS, where I took the product from zero to paying customers and continued to shape both the technical architecture and business outcomes. I have experience collaborating with US and global teams in English on a daily basis, mentoring junior developers, and leading frontend and full-stack delivery in remote environments. I am open to opportunities where I can contribute to scalable product development, strong engineering practices, and modern web architecture. ## Skills 36 capabilities[Agile](https://jobicy.com/talent/agile.md)[AWS](https://jobicy.com/talent/aws.md)[BFF](https://jobicy.com/talent/bff.md)[CI CD](https://jobicy.com/talent/ci-cd.md)[Claude Code](https://jobicy.com/talent/claude-code.md)[Code Review](https://jobicy.com/talent/code-review.md)[Docker](https://jobicy.com/talent/docker.md)[DynamoDB](https://jobicy.com/talent/dynamodb.md)[Express](https://jobicy.com/talent/express.md)[GitHub Actions](https://jobicy.com/talent/github-actions.md)[GraphQL](https://jobicy.com/talent/graphql.md)[JavaScript](https://jobicy.com/talent/javascript.md)[Jenkins](https://jobicy.com/talent/jenkins.md)[Jest](https://jobicy.com/talent/jest.md)[LLM](https://jobicy.com/talent/llm.md)[Material UI](https://jobicy.com/talent/material-ui.md)[Mentoring](https://jobicy.com/talent/mentoring.md)[Microservices](https://jobicy.com/talent/microservices.md)[Microsoft Azure](https://jobicy.com/talent/microsoft-azure.md)[MongoDB](https://jobicy.com/talent/mongodb.md)[MySQL](https://jobicy.com/talent/mysql.md)[NestJS](https://jobicy.com/talent/nestjs.md)[Next.js](https://jobicy.com/talent/next-js.md)[NoSQL](https://jobicy.com/talent/nosql.md)[PostgreSQL](https://jobicy.com/talent/postgresql.md)[React](https://jobicy.com/talent/react.md)[React Testing Library](https://jobicy.com/talent/react-testing-library.md)[Redux](https://jobicy.com/talent/redux.md)[Scrum](https://jobicy.com/talent/scrum.md)[Socket.IO](https://jobicy.com/talent/socket-io.md)[SonarQube](https://jobicy.com/talent/sonarqube.md)[SQL](https://jobicy.com/talent/sql.md)[System Design](https://jobicy.com/talent/system-design.md)[Technical Documentation](https://jobicy.com/talent/technical-documentation.md)[TypeScript](https://jobicy.com/talent/typescript.md)[Vercel](https://jobicy.com/talent/vercel.md) ## Experience Career history ### Full Stack Software Engineer (Feature Lead) · 2am.tech Jun 2024 – PresentDeliver full stack features on production systems with TypeScript, GraphQL, Node.js, and Next.js.
