Djordje Kartaljevic — AI Engineering and Full-Stack Development

LinkedIn LoveGift live product GitHub projects

I turn ambitious ideas into testable, deployable products—across AI workflows, web platforms, and mobile applications.

What I build

AI systems

RAG, structured LLM outputs, agent workflows, computer vision, evaluation, and automation with dependable boundaries.

Full-stack products

Responsive interfaces, APIs, authentication, payments, background jobs, data, deployment, and iteration.

Mobile experiences

Product-focused iOS and Android work using Swift, SwiftUI, UIKit, Kotlin, Firebase, and thoughtful UX.

Featured work

LoveGift

A live personalized-gifting product with checkout, shareable delivery, QR flows, and production deployment.

SaaS Web Payments Product

Audiobook Pipeline

A creator-focused AI workflow for transcription, translation, multilingual narration, jobs, storage, and billing.

Python Flask React OpenAI Redis / RQ

IBM RAG & Agentic AI Showcase

Reliable extraction and agentic-AI coursework with typed outputs, validation, tests, and CI.

Python Pydantic watsonx.ai Granite

Real-Time Gender Fusion

Computer-vision fusion with confidence weighting, tracking, smoothing, and explicit uncertainty handling.

PyTorch OpenCV MediaPipe YOLO

OutZone

A product concept for gamified social-confidence challenges and AI-assisted reflection.

iOS SwiftUI Product Design

TihiHeroj

Privacy-conscious violence-reporting flows, localization, and sensitive mobile UX.

Swift SwiftUI Firebase

Engineering approach

I care about more than making a demo run. My strongest repositories aim for explicit architecture, reproducible setup, validation and automated checks, honest limitations, and a result that another engineer can evaluate quickly.

Core stack: Python · Flask · Node.js · React · Next.js · TypeScript · Swift · SwiftUI · Kotlin · Firebase · Supabase · Redis · GitHub Actions

Currently building toward: a production-grade LangGraph project with explicit state, dependable tool contracts, evaluation, memory, observability, and human approval at consequential steps.
