Software Engineering for Impact and Innovation

What I Do

As a Senior Software Engineer - Mobile at SunStrong Management, I lead full-cycle development of mobile solutions that empower SunPower’s solar and storage ecosystem. I architect and deliver user-centric apps that streamline commissioning and monitoring for over 5,000+ field technicians and offer 65,000+ homeowners intuitive control over their energy systems.

  • Contributed extensively to mySunPower, a customer-facing app that provides real-time insights and system control, improving energy engagement and satisfaction.
  • Key engineer behind ProConnect (CM3), developed from the ground up with a modular architecture and reusable design system to accelerate future development.
  • Automated mobile DevOps workflows using Fastlane and GitHub Actions, optimizing builds and enabling consistent releases on both the Google Play Store and Apple App Store.
  • Engineered a React Native Scanner Component for multi-code scanning, eliminating hardware dependencies and saving ~$150,000 annually.
  • Optimized IoT commissioning via BLE and WiFi, boosting system efficiency by 20%.
  • Collaborated with QA to develop test strategies that reduced production bugs and improved app ratings by 20%.
  • Reduced CI pipeline billing minutes by 25% and cut deployment times by 30% through test automation and build optimization.
  • Improved firmware update workflows in coordination with hardware teams, decreasing update time and enhancing reliability.
  • Modernized legacy Cordova applications, improving performance and cutting maintenance time by 25%, facilitating a smoother transition to modern tech.
  • Integrated and maintained GraphQL APIs to streamline data fetching, reduce over-fetching, and improve mobile and web app performance.
  • Contributed to cross-platform consistency by supporting a companion web application, ensuring cohesive features and responsive design across web and mobile experiences.
  • Implemented Mixpanel to monitor user behavior and feature adoption, enabling data-driven decisions that enhanced user engagement and retention.
  • Integrated Sentry for real-time crash and error tracking, significantly improving incident response times and overall app stability across platforms.

I specialize in building resilient, scalable mobile and web platforms that drive measurable impact and user satisfaction.

Projects Beyond Work

Outside of my professional role, I actively build and maintain personal and open-source projects that align with my interests in technology and societal impact:

  • Marriage Game Point Calculator: A cross-platform mobile app used by thousands to score a traditional Nepali card game. Available on Google Play and App Store.
  • Immersive Learning Platform (in-progress): A web app for education using AI-powered video summarization and MongoDB-backed analytics, part of a broader research initiative.
  • NepalBhasa App: Collaborated with Dabuli, a US-based nonprofit, to build a platform that hosts a rich Nepalbhasa dictionary and cultural resources aimed at preserving the Newar language. This project reflects my commitment to giving back to my roots and promoting cultural awareness through technology.
  • Hamro Blood Bank: Developed a solution to help address the critical issue of blood shortage in Nepal by streamlining access to compatible blood donors. This app focuses on saving lives through rapid donor-matching in time-sensitive medical situations.
  • BLE Utilities & Firmware Tools: Built utilities for scanning, pairing, and secure communication with IoT devices using React Native and AES encryption.
  • Regularly contribute to open-source projects and mentor early-stage developers.

These projects reflect my commitment to lifelong learning, community involvement, and technical leadership.
