I build developer tools, CLI packages, web applications, automation workflows, and AI-assisted engineering systems.
My focus is simple: clear scope, working MVPs, testable workflows, readable documentation, and shipping things that actually work.
I am a Computer Programming student at Ondokuz Mayıs University in Samsun, Türkiye.
I like building practical software that has a real workflow behind it: npm packages, developer tools, local-first automation systems, web apps, and research-style prototypes. My recent work focuses heavily on AI-assisted developer tooling and making AI coding workflows more structured, testable, and auditable.
- Building:
Codex Engineering Workflow Pack,next-secure-check,Nihongo Learn,BioVoid, and my portfolio - Learning: SQL, algorithms and data structures, debugging, testing, code reading, documentation, and software architecture
- Interested in: internships, open-source developer tools, AI-assisted engineering workflows, practical software projects, and research-style prototypes
- Working style: define the scope first, build in small iterations, test what matters, document decisions, and improve through feedback

Personal portfolio site built to present my projects, learning path, CV, and internship availability. Stack: Next.js, TypeScript, Tailwind CSS, Framer Motion Focus: personal branding, project presentation, responsive UI, animation, CV alignment Live: setrathex.com.tr |
I keep this profile focused on public, working, and explainable projects. Private experiments are added here only after they are ready to be shared. Focus: clean releases, practical demos, better documentation, and stronger validation. |
Right now I am improving my developer-tooling projects and building stronger engineering workflows around them.
- Codex Engineering Workflow Pack: local-first Codex skills, Coordinator Mode runtime, policy enforcement, guarded dispatch, reviewer gates, parallel worker workflows, and future multi-model adapter architecture
- next-secure-check: deterministic Next.js security checks, SARIF output, CLI reliability, and test coverage
- Portfolio/CV alignment: keeping my public projects, README files, portfolio site, and internship profile consistent
Actively using: Python · TypeScript · JavaScript · Node.js · Next.js/React · Git/GitHub · SQLite
Tools and platforms: npm package publishing · GitHub Actions · SARIF · Git worktree · CLI development · Windows/PowerShell · Vitest
Touched in projects: FastAPI · Supabase · Oracle Cloud · PM2/Nginx · Docker basics · Tailwind CSS · Biopython/ProDy
Currently strengthening: SQL · Algorithms and data structures · Debugging · Testing · Code reading · Documentation · Software architecture
I use Codex CLI, Claude Code, GitHub Copilot, Cursor, and other AI coding tools as support for research, planning, code generation, review, debugging, testing, and documentation.
I still manage the scope, technical decisions, validation, release process, and project direction myself.
A lot of my recent work focuses on making AI-assisted development more structured:
- clear PRDs and roadmaps
- smaller implementation slices
- TDD/debugging loops
- worktree-based isolation
- review gates
- local-first workflow discipline
- safer AI execution through explicit file scopes and policy modes
I am open to software development internships, open-source collaboration, and practical developer-tooling projects.
I am especially interested in:
- developer tools and CLI projects
- web applications with clear user value
- AI-assisted engineering workflows
- automation and productivity tools
- security-focused tooling
- research-style software prototypes
