Nikola G. AI, Cloud and General Development

My name is Nikola G. and I have over 1 year of experience in the tech industry. I specialize in the following technologies: AI Implementation, AI Text-to-Image, AI App Development, NLP Tokenization, Deep Learning, etc.. I hold a degree in , Bachelor of Engineering (BEng). Some of the notable projects I've worked on include: Multi-Document RAG with LangGraph, Fully Autonomous AI Agent for Google Drive Document Processing, LLM Fine-tuning, UNet-based edge colorization and cartoonization system, Stateful AI Agent using Langgraph and Azure Cosmos DB, etc.. I am based in Prijepolje, Serbia. I've successfully completed 13 projects while developing at Softaims.

My passion is building solutions that are not only technically sound but also deliver an exceptional user experience (UX). I constantly advocate for user-centered design principles, ensuring that the final product is intuitive, accessible, and solves real user problems effectively. I bridge the gap between technical possibilities and the overall product vision.

Working within the Softaims team, I contribute by bringing a perspective that integrates business goals with technical constraints, resulting in solutions that are both practical and innovative. I have a strong track record of rapidly prototyping and iterating based on feedback to drive optimal solution fit.

I'm committed to contributing to a positive and collaborative team environment, sharing knowledge, and helping colleagues grow their skills, all while pushing the boundaries of what's possible in solution development.

Experience Highlights

Multi-Document RAG with LangGraph

Intelligent RAG pipeline for querying multiple financial PDFs with automatic document routing. https://github.com/nikolagojakovic/LangGraph-Agentic-Rag

Fully Autonomous AI Agent for Google Drive Document Processing

A solid “fully autonomous” design is an event-driven pipeline: Google Drive change events trigger an orchestrator that plans work, runs document tools (extract/OCR/classify/signature), writes results

LLM Fine-tuning

This project fine‑tunes the Mistral language model with LoRA adapters on the Dolly 15k instruction dataset to maximize ROUGE‑L performance for text generation tasks. It provides a reproducible trainin

UNet-based edge colorization and cartoonization system

This project is a UNet-based edge colorization and cartoonization system that turns regular photos into stylized, cartoon‑like images. It uses Canny edge detection as an additional input channel to a

Stateful AI Agent using Langgraph and Azure Cosmos DB

This project is an Azure-based stateful travel assistant that uses GPT‑4.1 and Azure Maps to answer route and traffic questions from a client app. The client sends a request to an Agent API, which coo
