• Model, index, and optimize MongoDB schemas using compound indexes, aggregation pipelines, and transactions on replica sets
• Develop responsive React.js user interfaces using modern patterns including hooks, state management, and component-level testing
• Implement authentication and authorization using JWT and role-based access control with secure middleware patterns and OWASP-aligned input validation
• Integrate with EVM-based blockchain systems (Ethereum, Polygon, Arbitrum, Base), including wallet interactions, transaction lifecycle handling, and on-chain/off-chain reconciliation
• Deploy and operate services on AWS using Docker and CI/CD pipelines, with structured logging, monitoring, and on-call participation
• Write automated tests (unit, integration, end-to-end) using Jest, Mocha, Supertest, or similar frameworks
• Conduct code reviews, mentor mid-level engineers, and contribute to engineering documentation and best practices
• Collaborate with product, design, and engineering leadership across time zones to scope features, define API contracts, and deliver end-to-end

• Strong expertise in MongoDB, Express.js, React.js, Node.js, and TypeScript across both client and server

• Familiarity with Docker, GitHub Actions, and modern CI/CD workflows
• Experience writing automated tests across unit, integration, and end-to-end layers using Jest, Mocha, Supertest, Playwright, or Cypress
• Solid understanding of backend and frontend security practices
