About me

I am a Computer Programming student at Ondokuz Mayıs University in Samsun, Türkiye.

My work focuses on developer tooling, web security, CLI design, practical automation, and local-first AI-assisted engineering workflows. I like projects with clear scope, testable behavior, readable documentation, and releases that can be explained.

AI is part of my workflow, but not an autopilot. I still own the scope, technical decisions, validation, release process, and project direction.

Currently building

  • next-secure-check
  • Codex Engineering Workflow Pack
  • Pagonic
  • Nihongo Learn
  • BioVoid

Featured projects

next-secure-check

Deterministic security checks for Next.js projects before PR or deploy. Built for practical review signals around leaked secrets, risky API routes, weak config, XSS patterns, raw SQL patterns, and missing safeguards.

Stack: TypeScript · Node.js · Next.js · Vitest · SARIF · GitHub Actions

Status: v0.3.0 on npm · rule-based · no AI at runtime

Links: Repository · npm

Codex Engineering Workflow Pack

Local-first workflow toolkit for disciplined Codex / AI-assisted development.

It structures AI coding around planning, worktree isolation, worker/reviewer flows, policy guardrails, adapter config, and review gates.

Stack: Node.js · JavaScript · CLI · npm · Git Worktree · Markdown

Status: v0.3.1-beta.0 on npm · Coordinator Mode · adapter config hardening

Links: Repository · npm · Release notes

Pagonic

Security-aware Python ZIP inspection and safe extraction toolkit. The core idea is simple: inspect archives before extracting them, with deterministic risk signals and safer extraction gates.

Stack: Python · ZIP tooling · CLI · pytest · optional PyQt6 GUI

Status: v0.3.0 public alpha

Links: Repository

Nihongo Learn

Japanese learning MVP for Turkish speakers with kana practice, SM-2 review logic, quizzes, XP/streak tracking, mini stories, and N5-style practice.

Stack: Next.js · TypeScript · Tailwind CSS · Zustand · Supabase plan

Focus: learning flow · frontend architecture · state management

Links: Repository

BioVoid

Experimental computational biology prototype for protein motion, geometry-based cavity analysis, Atlas indexing, and FastAPI/React exploration.

Stack: Python · Biopython · ProDy · SciPy · FastAPI · SQLite

Note: research-style prototype, not a clinical or diagnostic system

Links: Repository

setrathex portfolio

Personal portfolio site for presenting projects, learning path, technical direction, and public work.

Stack: Next.js · TypeScript · Tailwind CSS · Framer Motion

What I am building toward

  • Better security-focused developer tools for real project workflows
  • Local-first AI-assisted engineering systems with clearer review gates
  • Reliable CLI packages with tests, release notes, and practical docs
  • Web apps that are small enough to ship and useful enough to maintain
  • A stronger public portfolio around open-source projects and practical tools
