What I'm looking for

I'm looking for an opportunity to apply my computer engineering and full-stack development work while growing through collaborative engineering challenges, design thinking, and professional development.

I'm building computer systems from first principles, including a complete 16-bit RISC microprocessor and ALU designed from NAND logic gates.

I implemented Harvard Architecture with dedicated ROM and RAM, instruction fetch-execute control paths, memory bus routing, multi-bit registers, RAM modules, and a loadable program counter. I also built an ALU for bitwise manipulation, conditional branching, and arithmetic addition.

I engineered a full-stack task management website using Python, Flask, SQLite, HTML, and CSS. I designed relational schemas, parameterized SQL queries, secure authentication with password hashing, session management, and reliable client-server updates.

I'm pursuing a Computer Engineering degree at Missouri S&T with a 4.0 GPA and contribute to the Kummer Vanguard Scholars Program's engineering and design-thinking community.
