Hardware + 3D Visualization

• —Engineered a time-of-flight scanner with servo vertical sweeps (0-180°) and 360° stepper rotation to capture full-hemisphere distance scans up to 4 m
• —Built a network-accessible Three.js interface that streams points in real time with start, stop, and pause controls plus live telemetry
• —Implemented the point-cloud pipeline (spherical to Cartesian), export to PLY/PCD, and a simulation mode for hardware-free validation

Embedded Systems + API Integration

• —Designed an ESP32 controller with SPI TFT touch UI and a quadrature encoder using ISR-driven input decoding and gesture state machines
• —Implemented secure captive-portal provisioning with an async web server and encrypted NVS storage for Wi-Fi and OAuth credentials
• —Integrated the Spotify Web API with token refresh, resilient REST handling, and lyric retrieval via a fallback chain (LRCLIB and OVH)

AI Document Extraction + Automation

• —Built an extraction pipeline for receipts and medical bills that outputs structured records against a custom JSON schema
• —Automated PDF form completion and submission workflows using schema-driven mappings for internal operations at NETSOL Technologies
• —Supported stakeholder demos and rollout planning that helped move the solution from prototype to an official NETSOL product

PCB Design + Hardware Engineering

• —Designed a full 60% keyboard PCB in KiCad with Cherry MX footprints, routing constraints, and production-ready board files
• —Integrated an RP2040 (Raspberry Pi Pico) as the USB HID microcontroller for low-latency key scanning and host communication
• —Validated the design workflow end to end, from schematic capture to PCB layout review and firmware integration planning

PCB Design + CircuitPython

• —Designed a custom macropad PCB around the RP2040 with a compact layout optimized for desk workflows and macro-heavy tasks
• —Developed CircuitPython firmware to emulate keyboard input and trigger programmable multi-step shortcuts
• —Established a reusable hardware-plus-firmware template for quickly building future input devices

Conversational AI Agent

• —Built an agentic chatbot that combines conversational context handling with autonomous tool-driven task execution
• —Implemented structured planning and response pipelines to improve reliability for multi-step user requests
• —Designed extensible agent orchestration patterns to support additional tools and workflows over time

Bigmode Game Jam 2025

• —Developed a complete game jam entry under tight deadlines, balancing core mechanics, iteration speed, and scope control
• —Implemented gameplay systems and level flow focused on thematic coherence and player feedback loops
• —Collaborated through rapid test-and-polish cycles to deliver a stable submission within the jam window

Embedded Systems + Communication Protocols

• —Built a lockout buzzer system using two STM32 microcontrollers communicating over UART for low-latency event handling
• —Integrated PWM-driven audio cues and an LED matrix countdown to provide clear real-time feedback during rounds
• —Delivered a polished final prototype that earned a 96% overall grade in the ECE198 Project Studio course
