Case Studies

Projects

Real problems. Real solutions. Each project demonstrates how enterprise engineering discipline and AI integration work together in production.

Projekt 01

Speech Therapy Report Agent

Audio → AI reports for speech therapists

Live
Next.js FastAPI Groq (Whisper + LLaMA) Pydantic Python
Problem

Speech therapists spend hours writing therapy reports — time taken away from patients. Structured documentation is mandatory but manually time-consuming.

Solution

Audio recording of the therapy session → automatic transcription via Whisper (Groq) → structured, formatted AI report in seconds. The therapist corrects instead of writing from scratch.

Result

Fully functional prototype: audio upload → formatted therapy report with Pydantic-validated structure. Demonstrates an end-to-end AI pipeline with real-world application.

Projekt 02

RealizeTogether

AI platform for collaborative workflows

In Development
Next.js 16 Supabase FastAPI LangChain TypeScript Python
Problem

Enterprise teams need AI features that are secure, deterministic and integrable into existing system landscapes — not just chatbots.

Solution

Production-grade architecture with Next.js frontend, FastAPI backend and Supabase as data layer. AI integration via LangChain with Pydantic Structured Output — no "fire and hope", but validated outputs.

Result

Ongoing R&D platform as testbed for production-grade AI architecture patterns. Authentication, data layer and AI pipeline fully integrated.

Projekt 03

This Portfolio

Multi-provider AI backend with fallback resilience

Live
FastAPI LangChain Pydantic Astro Tailwind CSS Render
Problem

A portfolio backend demonstrating AI capabilities can't fail when a provider hits quota limits or goes down.

Solution

FastAPI with LangChain multi-fallback: 4 providers (Google Gemini, OpenAI, Groq, Anthropic) tried in sequence. Pydantic Structured Output for all endpoints — no manual JSON parsing.

Result

CV assistant, vision analysis, sentiment analysis and agentic chat live at sinanucar.com. Resilient operation even during provider outages.
