Portrait of Oguz Kaan Dere

About

Software engineering with a product and systems perspective.

I am a software developer with a Biomedical Engineering background and professional experience in enterprise frontend systems, Java/JavaScript full-stack work and hospital software.

My recent work focuses on AI-assisted products, local-first document workflows, RAG, OCR and interactive systems. I prefer explicit constraints, reviewable data and interfaces that help users make the final decision rather than hiding it behind automation.

During my transition to Germany, I focused on German language development, job-market alignment and building targeted engineering and game portfolio projects.

Product thinking

How I turn an idea into a working system

  1. 01

    Model vague real-world problems as explicit data structures, rules and review flows.

  2. 02

    Constrain AI with sources, schemas and clear refusal or uncertainty behavior.

  3. 03

    Separate retrieval, user data, AI explanation and the final user decision.

  4. 04

    Prefer local-first and BYOK patterns when user documents are sensitive.

  5. 05

    Build MVPs that are demoable, deployable and explainable.
