Computer Science Senior @ The University of Texas at Dallas (Graduating May 2027) // Texas Leadership Scholar

Welcome to my personal terminal. This site is engineered to be ultra-lightweight: outer visuals and project photography use 1-bit Atkinson dithering and lightweight ASCII motion, while keeping this MS-DOS viewport razor-sharp for effortless reading.

I build systems across the full hardware and software spectrum—from Go and Python backend services and self-hosted Linux homelab infrastructure, down to embedded motor control and 5.8 GHz phased-array RF antenna simulations.

// SYSTEM SPECIFICATIONS & TECHNICAL STACK

01. 5.8 GHz Vivaldi Phased Array & Power Divider

[STATUS: IN PROGRESS /]

STACK: Ansys HFSS | Keysight ADS | RF Microstrip Design | Wilkinson Power Divider

Undergraduate RF & electromagnetics research at UT Dallas modeling antipodal Vivaldi microstrip antennas and corporate feed networks for 5.8 GHz phased array systems.

Parametrically tuned exponential flare geometry and substrate dielectric dimensions in Ansys HFSS to minimize S11 return loss across the 5.8 GHz band.
Designed matched Wilkinson power dividers in Keysight ADS for high port-to-port isolation and coherent multi-element beamforming.

02. SyllaBuddy // Automated Syllabus Parser

[STATUS: IN PROGRESS /]

STACK: Go | Python (FastAPI / Flask) | Gemini API | Google Compute Engine (GCE)

Full-stack web platform that transforms unstructured university course syllabi (PDF/DOCX) into structured semester calendars, weighted grade calculators, and deadline alerts.

Refactored backend architecture into a streamlined service deployed on Google Compute Engine Linux VMs.
Combines high-speed Go/Python routing with structured LLM extraction schemas to handle complex multi-table academic schedules.

03. Self-Hosted Media Compression Discord Bot

[STATUS: ✓ COMPLETE]

Production utility bot providing /download and /compress slash commands to fetch, transcode, and target-size compress video/audio media on self-hosted Linux hardware.

Dynamically calculates two-pass/target-size video & audio bitrates via FFmpeg to guarantee outputs fit strict Discord upload limits (<10 MB).
Includes an integrated FastAPI fallback file server with an automated 24-hour disk sweeper exposed via Cloudflare Tunnels.
