Hire the Best Google Sheets Experts
in Serbia

With 9 years of professional experience and over 1,000 completed projects, I help startups, small, and mid-sized businesses make smarter, data-driven decisions by transforming raw data into clear, actionable insights. Using Google Sheets, I design interactive dashboards, automated reports, and performance-tracking systems that give businesses full visibility into their operations without the cost and complexity of traditional BI tools. I've worked with clients across a wide range of industries, including: - Mental health clinics - Real estate businesses - Transport and logistics companies - Restaurants and hospitality businesses - Schools and educational institutions - Financial institutions By giving business owners a clear understanding of their key metrics, I've helped multiple clients achieve over 50% revenue growth after implementing custom dashboards and data-driven performance tracking in Google Sheets. My mission is simple: help organizations truly understand their data, identify meaningful trends, and make confident strategic decisions. Here is what some of my clients say about me: "Dragan was extremely responsive and proactive. We weren't exactly sure what we needed but he was able to provide advice and deliver exactly what we needed. Would definitely recommend." "I’ve worked with Dragan multiple times, and every project has been exceptional. The dashboards he and his team build are not only interactive, but they also rival full accounting software. I’m still amazed at what they can accomplish using Google Sheets. What impressed me most was the design team. That’s where the real magic happens. I shared a logo, and they created a whole design system around it with a clean color palette and a professional layout that looks like something out of The Economist. It’s awe-inspiring. I’ll continue working with them without hesitation. If you’re looking for quality, innovation, and a partner who takes pride in their craft, Dragan is the one."

I help founders and teams turn AI ideas into working products in weeks, not months. Instead of spending months experimenting with LLMs, tools, and architectures, I design and build MVPs that actually work in real business conditions. Typical results: – Working AI MVP in 2–4 weeks – Clear, scalable architecture (not a demo that breaks later) – Reduced risk before investing into full development 💡 What I do best – Turn raw AI ideas into working MVPs – Design production-ready AI architectures – Build agentic AI systems (multi-agent workflows, automation) – Develop RAG systems & knowledge-based AI – Integrate LLMs into existing products and workflows I focus on execution and outcomes — not just code. 🧠 Who I work with – Startups validating AI ideas – Founders building MVPs for investors or internal use – Teams внедряющие AI в существующие продукты – Businesses looking to automate workflows with AI 💬 Not sure where to start? I offer short consultation calls where we: – break down your idea – define architecture – identify fastest path to MVP Most of my projects start this way. ⚙️ Typical engagement – AI MVP / Proof of Concept: $1,500 – $5,000+ – Architecture & planning: via consultation – Ongoing development: after MVP validation Most of my work is fixed-scope (MVPs, PoCs). If you need someone who can not only build, but also think through your AI product — let’s talk.
