Multi-tenant ticketing, from online checkout to the gate.
Built to help a cash-only raceway sell tickets in advance for an event with upfront costs. Each track has its own catalog, with Stripe Connect payments and refunds, Apple and Google Wallet tickets, and QR admission scanning.
Invoicing and time tracking for independent work, on web and mobile.
Manage clients, track time, send recurring invoices, and follow payments across a web app and mobile companion. The Expo app includes iOS widgets, while shared domain logic and a background job worker support the product across platforms.
A native macOS system monitor inspired by Windows 11 Task Manager, with live process controls and detailed performance diagnostics.
Built in SwiftUI, Puter combines process management with live CPU, memory, disk, network, GPU, battery, thermal, and fan telemetry. It includes sortable and resizable process tables, application grouping, startup and service management, per-app history, dependency inspection, diagnostic sampling, and native JSON exports—all in a macOS interface with persistent preferences, light and dark modes, and accessibility support.
Shared event photo albums, from guest uploads to a moderated gallery.
Guests contribute photos through a shared link, and hosts review submissions before publishing them to the gallery. Direct-to-storage uploads, background image processing, and HEIC support handle the media pipeline; display copies strip location metadata while original files are retained.
A publishing platform for multiple sites, with one shared codebase.
Visual page editing, revisions, draft previews, scheduled publishing, and custom domains in a multi-tenant platform. Includes a media library, themes, forms, and roles, with atomic publishing for changes that need to go live together.

Technologies: Next.js, TypeScript, PostgreSQL, Docker, DigitalOcean.
A modular web-based experimental platform for human-robot interaction studies using the Wizard of Oz experimental paradigm.
Architected full-stack web application for managing HRI experiments with real-time robot control interfaces. Implemented WebSocket-based bidirectional communication protocols for low-latency robot teleoperation. Designed RESTful API leveraging Robot Operating System with JSON-defined plugins for extensibility across multiple robot platforms. Created comprehensive logging system capturing interaction data, timestamps, and experimental conditions for reproducibility. Technologies: Next.js, React, TypeScript, Node.js, WebSockets, PostgreSQL, Docker.
LoRA fine-tuning and GGUF quantization pipeline for on-device LLM inference. Fine-tuned Llama 3.2 3B improved recall by +0.192 over the generic baseline at roughly half the latency.
End-to-end pipeline for fine-tuning a small LLM on structured JSON extraction tasks, then deploying the result on-device. Used LoRA adapters on Llama 3.2 3B via MLX (Apple Silicon) and evaluated across four artifacts: generic F16, generic Q4_K_M, fine-tuned F16, and fine-tuned Q4_K_M. The deployable artifact — fine-tuned Q4_K_M GGUF — achieved 0.961 recall and 100% JSON validity at 2.91s average latency on llama.cpp, compared to 0.780 recall and 6.65s for the generic F16 baseline. Quantization after fine-tuning cost only 0.011 recall while cutting latency in half. Evaluation ran on a 106-case held-out set with automated recall, JSON validity, and schema validity scoring.
Removes the F1 Halo safety arch from onboard visor-cam footage using classical CV mask detection and neural inpainting. Final project for Image Processing and Analysis.
The Halo is a mandatory titanium arch on all F1 cars. It saves lives but cuts through the most interesting part of onboard footage. This project removes it cleanly from visor-cam video using two stages. Stage one: classical CV mask detection — Sobel-Y gradient detection for the arch edge, a robust probe-and-fit keel detector with outlier rejection and temporal jump guards, and explicit geometry construction to avoid over-masking. Stage two: two inpainting methods compared side by side — LaMa (Fast Fourier Convolution network, per-frame spatial inpainting) and RAFT optical flow with backward warp and distance-transform blending for temporal coherence across 300 frames at 60fps.
A complete implementation of a general-purpose computer system, from NAND gates to a high-level object-oriented compiler.
Built a complete computer system from the ground up as part of the Nand2Tetris course (ECEG 431). Starting with a single NAND gate, I designed and simulated all hardware components including logic gates, ALU, RAM, and the CPU. On the software side, I developed an assembler, a virtual machine translator, and a compiler for a high-level object-oriented language, culminating in a fully functional Operating System. This project provided a deep, demystified understanding of how computers actually work under the hood.
A web application that converts PDFs to Markdown files.
Uses OCR and PDF parsing to extract text and convert it to Markdown, for easy editing and formatting.
Custom microcontroller-based control system for hydrogen fuel cell regulation and reaction monitoring.
Designed embedded control system for autonomous hydrogen fuel cell-powered vehicle using finite state machine architecture. Implemented real-time sensor fusion combining spectrometer readings and power monitoring with calculated stopping algorithms. Developed PlatformIO-based build system with hardware abstraction layer for testing and simulation. Achieved precise distance control (±10cm) through chemical reaction timing at AIChE National Competition. Technologies: C++, Arduino, PlatformIO, I2C/SPI protocols, finite state machines.
