• Defined technical roadmap and user experience flows based on product vision discussions.
• Managed and mentored 2 Flutter interns, conducting code reviews, pair programming, and architecture sessions.
• Worked closely with backend engineers to define and refine REST API contracts, authentication flows, and error handling standards.
• Integrated Twilio for messaging and OneSignal for push notifications, ensuring reliability and scalability.
• Led performance profiling and implemented improvements, achieving faster load times and reduced memory usage.
• Enforced testing strategy with unit, integration, and widget tests across all major features.

• Refactored large legacy Flutter codebase and introduced Clean Architecture principles.

Collaborated in a team to design and implement a full-featured Unix shell in C, replicating functionalities of bash and zsh. The project involved building a complete shell pipeline — from lexical parsing to command execution — with advanced features and strict POSIX compliance.

• Worked on lexer and parser modules for interpreting complex shell syntax.
• Implemented I/O redirections, pipes, and logical operators (&&, ||) in command execution.
• Developed built-in command support (cd, echo, exit, etc.) and environment variable management.
• Participated in implementing job control (background/foreground processes, signal handling).
• Used Git for version control and coordinated via regular team syncs and code reviews.
• Shell command interpreter with custom parsing, process management, globbing, and command history.
• Hands-on experience with fork, execve, pipe, wait, signals, and file descriptors.
• Tech: C, POSIX System Calls, Process Control, Git, Team Collaboration.
