Projects

Student, 15411 Compiler Design

Carnegie Mellon University

Jan - May 2023

  • Worked as a team of two, finished implementing a C0 compiler using Rust, targeting x86-64.
  • Implemented frontend, code elaboration, IR generation.
  • Implemented modern language features such as Algebraic Datatypes and Nested Pattern Matching.
  • Considerably optimized the compiler via register allocation, hot path heuristics, and purity analysis. Achieved approx. 67% of the performance of GCC -O1.

Developer, TaggyTime

Personal Project

Feb 2023 - Present

  • Developing a program in Rust to optimize users' schedules by minimizing peak workload.
  • Implemented an algorithm that parses a Google Calendar and computes load factors for individual tasks
  • Designed numerical refinement types to make complex computations verifiably correct

Academic Experiences

Teaching Assistant, 15251 Theoretical CS

Carnegie Mellon University

Sep - Dec 2022

  • Hosted weekly recitations and office hours; graded homework and exams; helped revise grading rubrics.
  • Flexibly drew connections between course material and each student's technical background; received 100% positive student feedback for office hour interactions.

Student Researcher, Planar Graph Theory

Carnegie Mellon University

May - Aug 2022

  • Worked in a team of 3 and guided by Professor Aristotelis, conducted research on the Projective Amalgamation Property of connected planar graphs.
  • Derived an algorithmic proof for the existence of connected epimorphisms induced by some face of a planar graph.
