Logic & CMOS Studio

Browser tool for Boolean logic, truth tables, K-maps, simplified equations, Verilog, and static CMOS pull-up / pull-down schematics.

Problem

Logic classes often split truth tables, K-maps, Verilog, and transistor reasoning into separate tools.

Build

One browser studio connects Boolean input to simplified equations, generated HDL, and static CMOS views.

Signal

Shows hardware reasoning across abstraction layers instead of stopping at a polished interface screenshot.

Built around logic-to-layout reasoning
Interface goal compare views quickly

The project emphasizes traceability between Boolean input, minimized logic, generated Verilog, and static CMOS structure.

Hardware Prep Tool / React / TypeScript Structured practice for hardware interviews

Hardware Interview Trainer

Local-first interview practice app with a large question bank, mock rounds, review history, progress analytics, and JSON import / export.

Problem

Hardware prep is hard to repeat when questions, missed concepts, and timing live in scattered notes.

Build

Timed sessions, review history, analytics, and import/export turn practice into a durable loop.

Signal

Local-first data keeps the tool useful across multiple sittings without making prep feel heavy.

Hardware Prep Analytics Local-first
Details
Built around repeatable practice loops
Data model portable local progress

Question sessions, missed-question review, and analytics are designed to keep hardware interview prep structured over multiple sittings.

macOS Utility / Swift / C++ Native utility with privacy-first file handling

MarkMacZip

Archive utility for macOS that compresses and extracts common formats, supports password workflows, and keeps files on device.

Problem

Archive workflows are frequent enough to deserve a focused native utility instead of a loose script.

Build

Compression, extraction, passwords, job history, and releases are wrapped in a Mac-first interface.

Signal

The project balances product polish with privacy-first local file handling.

macOS Compression Privacy
Details
Built around native file workflows
Product focus local-only archive handling

The app frames compression, extraction, password handling, and release delivery as a polished desktop utility rather than a script wrapper.

Quarter Project Reports

MAGE RTL generation report cover
RTL Generation Research / Python / VerilogEval Memory improved raw pass count by 3 tasks

MAGE RTL Generation: Routing + Memory

Extended a multi-agent Verilog generation flow with failure routing, route-specific repair prompts, edit acceptance guards, and task-local debugging memory.

Problem

LLM-generated RTL can compile, simulate, and still fail from interface, timing, or behavioral mismatches.

Approach

Classified failures into syntax, interface, logic, or ambiguous routes and preserved candidate checkpoints per task.

Evidence

Routing cut estimated cost and runtime by 3.9%; memory raised full-set raw passes from 138/156 to 141/156.

Benchmarked on VerilogEval-V2
Control layer routing + local memory

The report frames routing as an efficiency control and memory persistence as the stronger correctness signal for future combined experiments.

GPU-accelerated GGM tree report cover
CUDA Cryptography / C++ / Keccak + Spongent Depth-20 speedups: 1030x Keccak, 1675x Spongent

GPU-Accelerated GGM Tree Construction

Implemented full GGM tree construction on CPU and CUDA GPU with Keccak-f1600 and Spongent-128 PRF backends.

Problem

GGM trees need millions of PRF evaluations, making throughput the bottleneck for protocol-scale workloads.

Approach

Used a flat breadth-first memory layout and one GPU thread per parent node to expand levels in parallel.

Evidence

Keccak reached 202M leaves/sec at depth 20; Spongent GPU time dropped from 2041 ms to 108 ms at depth 12 after optimizations.

The report compares software-friendly Keccak with hardware-native Spongent, showing why relative speedup and absolute throughput tell different performance stories.
