CS @ Purdue · Embedded & Security Research
Computer Science at Purdue. I build real-time embedded systems and ship security tooling.
About
I'm a CS student at Purdue (grad May 2027) and an undergraduate researcher working low in the stack: real-time DSP on FPGA/SoC, firmware, and signal processing. Right now I'm building a sub-24ms audio steganography pipeline on a Zynq-7000, and porting it to NVIDIA Jetson hardware.
Lately I've also been building software for AR glasses. On the security side I co-founded HackArmour, a search engine and CTF community, and I'm always up for more projects where embedded systems meet security.
Experience
Undergraduate Research Assistant · CYNICS Research Group, Purdue
- Architecting a real-time audio steganography system on a Zynq-7000 SoC, replacing a batch model with a streaming pipeline that cut input-to-output latency from 5s to under 24ms.
- Built a Direct Sequence Spread Spectrum (DSSS) “soft modem” in C to embed compressed bitstreams into carrier audio, with DMA double-buffering for glitch-free playback.
- Wrote a bit-exact MATLAB verification suite that diagnosed Q16 fixed-point quantization, RNG desync, and ADC saturation bugs in firmware.
- Porting the real-time streaming pipeline to NVIDIA Jetson hardware.
Undergraduate Researcher · Frederick National Laboratory (Purdue Datamine)
- Building an LLM-powered system to harmonize biomedical vocabularies, automating ontology alignment via Neo4j semantic search.
- Designed a Streamlit interface for researchers to batch-map terms, review alignments, and feed back corrections.
- Engineered backend pipelines to ingest and update evolving ontologies (NCIt, caDSR, UBERON) for cancer-research data integration.
Educator & Course Coordinator · LIFE Robotics
- Designed and delivered a web-development curriculum (JS frameworks) to 20+ students, including secure-coding and web-vuln modules.
- Mentored 3 teams (9 students) for the World Robotics Olympiad 2023; one team placed 3rd nationally.

Featured projects
HackArmour
Co-founded a cybersecurity search engine and CTF community. Built a Go protocol for the caching layer to handle cache-search interaction under high concurrency across 100k+ CVE records, and organized 4 global CTFs with 4,000+ participants.
Augmented Reality Lecture Platform
AR platform (Next.js + Python) for 3D-augmented lessons: OpenCV gesture recognition at 95% accuracy / <50ms, Manim projection onto docucam streams, and Gemini-driven visualization code generation.
