Work history

Work Experience

Cisco Systems, Inc — Software Engineer

  • Engineered a high-performance local caching mechanism in Spring Boot for the main Cisco CCRC webpage, reducing latency and improving performance by 20%.
  • Developed multiple Spring Boot APIs to connect BotService with the CCRC webpage, spearheading the integration of AI automation to significantly enhance operational efficiency.
  • Refactored and optimized critical codebases to achieve an A+ quality rating in SonarQube, ensuring high maintainability and reducing technical debt.
  • Implemented ML anomaly detection in Snowflake databases for attribute-level error monitoring, achieving 90%+ accuracy on production data.
  • Developed and maintained scalable enterprise REST APIs using the Spring Boot framework, collaborating with cross-functional teams to deliver robust solutions.

HackerEarth Inc — Software Engineer Intern

  • Created 60+ high-quality DSA problems for Online Assessments, focusing on diverse algorithmic topics.
  • Reviewed and corrected 150+ problem suites across multiple languages (C++, Python, Java, Golang).
  • Built a highly efficient test case generator capable of generating 10 million test case lines per second.
  • Conducted 30+ technical interviews, evaluating DSA knowledge for engineering intern roles.
  • Optimized problem difficulty distribution and enhanced assessment quality metrics for global contests.

Projects

That Time I Reincarnated As A Box — 2D Puzzle Platformer [Link]

  • Developed a narrative-driven 2D puzzle-platformer using Pygame featuring 8 challenging floors.
  • Implemented dynamic environments with atmospheric effects, light casting mechanics, and complex puzzles.
  • Features character progression, interactive NPCs, and an atmospheric soundtrack enhancing immersion.
  • Designed an intuitive control system with multiple movement options and progressive difficulty scaling.

Flight Navigation Optimization [Link]

  • Developed a full-stack solution for Aerothon 6.0 to calculate optimal flight routes and minimize aviation risk.
  • Modeled dynamic weather/traffic as a time-varying graph using Dijkstra's Algorithm for pathfinding.
  • Created Django backend for route risk calculations with relational database persistence and caching.
  • Built an interactive frontend to visualize flight paths using JavaScript with real-time route updates.

Generalized Persistent Lazy Segment Tree [Link]

  • Designed a generalized template for Persistent Segment Tree with Lazy Propagation using OOP principles.
  • Achieved 2x performance improvement in C++ over naive implementations for range operations.
  • Implemented version control allowing reversion to k-th update in O(log n) time (30x faster than binary search).
  • Provides comprehensive documentation and modular examples for competitive programming usage.
