Name : Hüseyin Tenlik
Education : Computer Engineering, Hacettepe University
Direction : Backend engineering → full-stack product delivery
Focus : APIs, authentication, security, databases and distributed systems
Mindset : Build it clearly. Test it properly. Deploy it for real.
I am a computer engineering student who enjoys turning backend logic into software that people can actually open, use and evaluate.
My work is centered around production-minded backend development: designing APIs, enforcing authorization rules, modelling relational data, testing critical flows and carrying applications beyond localhost.
A full-stack internship workflow platform developed for university processes, covering:
- JWT authentication and role-based authorization
- Internship report drafting, PDF upload and submission
- Company registration and administrative review
- Supervisor token and OTP verification
- Certification, coordinator assessment and final approval
- Semester, user, FAQ and announcement management
- Realistic production demo data for every major workflow state
I worked on the backend and production delivery: workflow APIs, authentication and authorization, database integration, business rules, security hardening, deployment configuration and live demo setup.
Frontend: React + Vite
Backend: Java + Spring Boot
Database: PostgreSQL
Infrastructure: Docker, Vercel, Render and Neon

+ Design APIs around real workflows, not only database tables.
+ Treat authorization as a backend responsibility.
+ Make failures observable and understandable.
+ Prefer explainable signals over unexplained scores.
+ Test the paths that can break the demo — and the product.
+ A project is not finished until someone else can run it.Portfolio: htenlik.com
