Technology Lead promotion confirmed for October 2026.

• Shape application structure and reusable engineering patterns across enterprise products, translating business requirements into maintainable implementation decisions.
• Build with React, TypeScript, Next.js, reusable component patterns, shared libraries, modern state/data tooling, and monorepo workflows.
• Coordinate with product, design, QA, backend, architecture, and DevOps partners to clarify requirements, manage dependencies, and carry features through review, release, and production support.
• Review technical approaches and code for module boundaries, reuse, state and API flows, performance, accessibility, security, and long-term maintainability.
• Support Agile delivery through estimation, sprint execution, defect resolution, production fixes, release coordination, and continuous improvement.
• Use AI-assisted engineering tools including Claude Code, GitHub Copilot, Gemini, and ChatGPT for exploration, debugging, refactoring, documentation, tests, and prototyping while keeping architecture and release decisions human-reviewed.
• Mentor and support other developers through code review, reusable patterns, debugging guidance, and engineering best-practice discussions.

• Developed 3+ frontend applications for data-analysis use cases, translating product requirements into responsive React interfaces.
• Built with React.js and Next.js while using Material UI to keep visual patterns consistent across screens and reusable components.
• Used Formik and Yup for structured forms, validation, and predictable user-input handling.
• Integrated multiple APIs and paid attention to secure, reliable request and response handling across data-driven flows.
• Created reusable global UI components to reduce duplication and keep interaction patterns consistent.
• Developed and implemented a standalone data-extraction agent that expanded the capabilities of a financial product.
• Worked with project managers, developers, and QA to identify delivery risks, resolve implementation issues, and improve testing approaches.
• Supported quality through debugging, validation, responsive behavior checks, and practical frontend best practices.

Bengaluru, Karnataka, India · On-site · Quality engineering

• Developed comprehensive automated-testing strategies for JavaScript-based product flows and regression scenarios.
• Expanded reported test coverage from 15% to 85% by building and maintaining 350+ JavaScript test cases.
• Integrated automated test execution into Jenkins pipelines so repeatable checks became part of the delivery workflow.
• Investigated failures, reproduced defects, and used test results to help development teams isolate reliability issues.
• Partnered with frontend and backend engineers to align testing strategy with product behavior and client requirements.
• Performed UI and regression checks across relevant devices and interaction paths to catch issues before release.
• Documented testing scenarios, execution outcomes, and defect context so issues could be reviewed and resolved efficiently.
• Built the quality-first habits that later shaped my frontend work: edge-case thinking, predictable states, maintainable changes, and release confidence.
