KRUNAL BADAMI
Summary
Senior software engineer & team lead specialising in React Native (mobile & TV) and Roku platform development. I deliver production-grade media apps with a strong focus on playback reliability (HLS/DASH), manual testing, quality and clear technical leadership.
Technical highlights:
- Expert in building cross-platform React Native apps and Roku channels with reliable playback and robust UX for mobile and TV.
- Experienced manual tester — thorough functional and regression testing, debugging and triage during releases.
- Hands-on team lead and technical project manager — mentoring engineers, running design sessions, and coordinating delivery with product and QA.
Experience
- Oversaw and delivered multiple projects with a strong focus on timely delivery, functional performance, and cost efficiency. Balanced client expectations, business goals, and development constraints.
- Bringing 6+ years of hands-on experience in React Native; consistently shipped high-quality mobile and TV apps while mentoring teammates and fostering collaboration.
- Integrated Firebase, analytics and Sentry into mobile apps to improve performance monitoring and enable data-driven decisions.
- Developed social media platforms with live streaming; implemented Google Cast and AirPlay support for multi-device media experiences.
- Gained deep experience in tvOS and Android TV development with React Native — built live streaming video players, custom carousels, grids and hero layouts optimised for remote navigation and TV UX.
- Implemented voice search and deep linking on TV platforms to improve accessibility and user convenience on large-screen devices.
- Worked extensively on Roku development using BrightScript/SceneGraph — created SceneGraph components, XML layouts and custom video playback tailored to Roku constraints.
- Optimised apps for TV hardware limitations (memory management, list rendering, remote-driven navigation) to ensure smooth performance on low-power devices.
- Built reusable cross-platform media modules to keep features consistent across mobile and TV apps, supporting scalable architecture and modular codebases.
- Strong in TypeScript and documentation — used JSDoc and structured interfaces to ensure clarity and speed up onboarding.
- Managed REST and GraphQL APIs with React Query hooks and axios; implemented offline caching and socket flows to keep apps functional with poor connectivity.
- Automated repetitive workflows with custom shell scripts (environment switching, code review helpers, version bumping, AAB verification, simple encryption) to streamline team productivity.
- Patched and improved node_modules when third-party libraries did not fit requirements — solving issues directly rather than waiting for external fixes.
- Prioritised code quality, performance and security through regular analysis and refactoring, leading to better user experience and trust.
- Applied modern JavaScript/TypeScript features (async/await, ES modules, structured types) in production projects, promoting clean code practices.
- Collaborated closely with designers, backend engineers, QA and product teams to translate complex requirements into polished apps.
- Reduced application crashes and errors by over 50% through thorough manual testing, bug-fixing and triage.
- Built cross-platform React Native mobile apps and admin web panels; improved performance and stability through measured optimisations.
- Implemented adaptive HLS playback plus background playback and platform-specific video/audio optimisation.
- Added unit & integration tests where needed and supported manual QA during releases.
- Developed APIs using PHP and Node.js and managed MySQL databases for production workloads.
- Led web projects built on CodeIgniter 3 and CorePHP MVC, improving maintainability and deployment velocity.
- Took ownership of a React Native app — upgraded the codebase from RN v55 → v59 and stabilised breaking changes.
- Implemented a camera filter feature for a social media app (image pipeline, basic shader-like effects, capture/save flow).
- Collaborated with QA to design and execute test cases; supported manual regression and release testing.
- Troubleshot and resolved complex technical issues (memory leaks, API race conditions, DB performance), maintaining uptime and UX quality.
- Applied security best practices and basic compliance steps (input validation, prepared statements, secure storage of secrets).
- Used analytics and monitoring (basic event tracking, error logging) to identify performance bottlenecks and optimise flows.
- Presented technical findings and lessons learned internally to share knowledge and improve team practices.
- Additional early-career responsibilities: assisted frontend builds, implemented responsive layouts, and supported mobile build/release tasks.
