Slack Overflow — Campus Q&A Platform

Product Lead & Full-Stack Developer

A full-stack Q&A platform I scoped and built end-to-end, including an AI-powered duplicate-detection feature that cleaned up the community's signal-to-noise ratio.

  • Scoped the MVP from scratch, defining the product requirements that shaped a full-stack Q&A platform with secure, role-based access.
  • Identified redundant, low-quality posts as the platform's core UX problem and shipped an AI-powered duplicate-detection feature that cut redundant posts by 30%.
  • Led a team of 3 through sprint planning and backlog grooming, shipping 5+ features on schedule with zero integration conflicts.

Logisim Evolution CPU

Systems Programmer

A from-scratch CPU datapath and assembler, built to understand computing at the lowest level.

  • Built a CPU from first principles — datapath, register file, and instruction set — to understand how design decisions ripple down to hardware constraints.
  • Validated the design against every test case, hand-translating 50+ lines of assembly into optimized hex with 100% opcode accuracy.
