I build full-stack web software, and I study how it runs underneath: C, Linux, and the machine.

I work with TypeScript, React, Express, and PostgreSQL to ship complete products, and I go below the abstractions with systems-level C and Linux internals to understand why they behave the way they do.

Projects

Two full-stack projects, built end to end.

Anonymous Conversation Platform

In design

A real-time, anonymous, topic-based platform for conversations that don’t need a permanent identity.

Anonymous session management
API design
Real-time communication
Security and abuse handling
PostgreSQL data modeling
Testing and documentation

Tech: TypeScript, React, Vite, Express, PostgreSQL

GitHub

DevNotes

Live

A full-stack note-taking app, built as a serious learning project and run as a real system.

Authentication and authorization
Clean API design
Search and pagination
Frontend architecture
PostgreSQL data modeling
Deployment and scaling

Tech: JavaScript, Node.js, Express, PostgreSQL, Vite

Systems and C

Beneath the web stack is memory, a kernel, and a CPU. I spend time there on purpose.

C programming: Pointers, structs, manual memory management, and how data is laid out in memory.
Linux internals: Processes, system calls, virtual memory, file systems, and tracing what the kernel is doing.
Computer architecture: Data representation, how the CPU and memory behave, and how compiled code maps to hardware.
Operating system concepts: Scheduling, memory management, and concurrency.

typedef struct {
    unsigned char *base;
    size_t cap, used;
} Arena;

void *arena_alloc(Arena *a, size_t n) {
    n = (n + 15) & ~(size_t)15;  /* 16-byte aligned */
    if (a->used + n > a->cap)
        return NULL;
    void *p = a->base + a->used;
    a->used += n;
    return p;
}

An arena allocator: the kind of small, low-level piece I like to write by hand.

Skills

Frontend: TypeScript, JavaScript, React, Vite, HTML, CSS
Backend: Node.js, Express, REST APIs, authentication
Database: PostgreSQL, data modeling
Systems: C, Linux internals, memory and pointers, OS concepts
Tools: Git, GitHub, Linux command line

Currently learning

Full-stack developmentBuilding complete systems from interface to database.
Backend engineeringAPIs, authentication, data modeling, reliability, and architecture.
C and systems programmingWriting lower-level code and understanding what it compiles to.
Linux internalsHow the kernel manages processes, memory, and files.

How I work

I like to build practical systems and then learn how they work under the hood. Mathematics, algorithms, and systems feed into each other, and I look for the connections instead of memorizing them.

I’m looking for a role where I can ship web software and keep going deeper into the layers it runs on.
