👋 I help businesses automate manual processes and connect their tools — building reliable systems with Excel, Google Sheets, VBA, Google Apps Script and custom API integrations. I'm also a finalist of the Excel World Championship (3rd globally in 2024, 7th in 2023). If disconnected tools, repetitive manual work, or messy spreadsheets are slowing you down, I build solutions that fix that — and keep working long after the project ends. 🏆 Competitive Excel background Placing 3rd worldwide in the Excel World Championship means I'm comfortable with complex logic, large datasets, and performance-critical builds. You get solutions that are efficient and robust, not just functional. 🔗 What I specialize in 📌 API integrations — connect CRMs, marketing platforms, payment tools, and internal systems so your data flows automatically 📌 Process automation — replace manual, error-prone tasks with reliable workflows (VBA, Google Apps Script, no/low-code) 📌 Spreadsheet solutions — custom Excel & Google Sheets tools built around your exact workflow 📌 Dashboards & reporting — clear, decision-ready insights pulled together automatically 📌 Fixing & optimizing existing files or systems that are slow, fragile, or hard to maintain 🚀 I also build custom apps and lightweight internal tools / CRMs for teams that have outgrown spreadsheets — reach out if that's where you're heading. 👉 Not sure what should be automated yet? No problem. If a process feels messy, slow, or unclear, I'll map it out with you, break it down step by step, and recommend what's worth automating — and what isn't. ✅ What you get working with me ✅ Time savings — less manual work, more focus on what matters ✅ Accuracy & consistency — fewer errors through automation and validation ✅ Clear reporting — dashboards built for decisions, not decoration ✅ Cost efficiency — better processes instead of more headcount ✅ Tailored solutions — built for your business, not a generic template ⚙️ Examples of projects I can help with 📊 Automated Excel / Google Sheets reporting systems 🔗 API integrations between your tools and data sources (marketing, payments, CRMs, etc.) ⚙️ Custom VBA macros & Google Apps Script automations 💰 Pricing calculators with client-ready PDF generation 📧 Mass email & notification tools 🔄 No-code / low-code integrations between systems 🧩 Custom system-to-system data pipelines 🛠️ Internal tools & lightweight CRM / app builds 🎓 Excel & automation training for you or your team I'm reliable, detail-oriented, and focused on solutions that hold up long-term — not quick hacks. Communication is clear, timelines are respected, and I'll flag improvements beyond the original scope when they'll genuinely help. If you want to simplify your workflows and automate the boring stuff, reach out — I'd be glad to discuss your project and propose the right solution.

I have 15 years of experience in data processing, management process improvement, and optimization using Microsoft Excel. I’m used to working with large datasets containing hundreds of thousands of rows and can help you save time by automating and simplifying your daily work in Excel. I provide solutions both with standard Excel functions and formulas (LOOKUPs, IFs, PivotTables, etc.) and with Excel VBA programming. Here are some types of projects where I can deliver great results: Data manipulation – cleaning, comparing, and combining data from multiple sources; Excel macros – automation for daily, monthly, or yearly reporting, or other routine tasks; Excel formulas and logic – creating or fixing formulas for smarter calculations; Data visualization – clear, interactive, and insightful charts and dashboards; Automated file generation – creating PDFs, CSVs, or folders directly from Excel data; Data analysis – extracting insights and summaries from complex datasets; Custom Excel solutions – whenever something is done manually and repeatedly, there’s always a way to semi-automate it and save time. My goal is simple: to help you save time and work smarter in Excel.

I have experience in: - Project managing, - GIS, - Land Consolidation, - Photogrammetry, - LiDAR, - Mapping and - Programming Photogrammetry expert: I was involved in orthophoto production (project manager or expert) for more then 78000km2 of orthophoto maps (plans) and DTM in Serbia and BiH. I did photogrammetric data processing including production line setup, bundle adjustment, digital terrain model generation, quality control of orthophoto and digital terrain model, with images taken with the standard photogrammetric camera and with Drone technology. Point cloud classification and DTM production from point cloud data. GIS expert: I was involved in design, establishment, data preparation (spatial and alphanumerical data - ETL data processing), data integration, data quality control check using different GIS software (AutoCAD, Bentley, ArcGIS, Manifold, QGIS) and different RDBMS (ArcGIS personal database, MySQL, Postgres) for clients who were mostly municipalities. Land Consolidation: setup production line, development consolidation plan that covering new road network, channel network, arable blocks position, working with LC Commision and Board of Participant, preparation report inline with methodology and good practice, Management, and programming. Programming: In all those projects I did programming staff depending on project and possibilities of automatization: for land consolidation project I developed the application which deals with spatial and alphanumerical and covers procedural all aspect of a Land consolidation process; for surveying projects, I developed a lot of VBA function for AutoCAD; for LiDAR projects, I developed the methodology for increasing accuracy of the final delivery using ArcGIS software for processing of LiDAR data. A lot of working time a spend processing alphanumerical or spatial data, and using excel, different RDBMS (mostly MySQL) or writing code (VB or C#, sometimes python) which would give me exactly format and parsing data as I need.
