I'm Adnan, an Excel developer and AI automation consultant with an engineering degree and over 10 years of freelancing behind me. Businesses come to me when their data lives in chaos, their reports take hours to build by hand, or their team is drowning in repetitive work that a well built system should be doing for them. What I build: Excel and Google Sheets systems with VBA, macros, and formulas that stay fast and accurate at scale. I've delivered a 32,255 SKU catalog system, a 26 region sales control tower running on 1,624 formulas, and a 3,544 product pharmaceutical pricing engine. Financial models and forecasting tools, including a 23 sheet investment P&L model, budget trackers, and dashboards that investors and management actually trust. AI and workflow automation using Make.com, n8n, Zapier, Power Automate, and custom AI agents, so leads, emails, reports, and data entry run on autopilot. Data cleanup, migration, and business intelligence with Power BI and Python, turning messy exports into clean, decision ready reporting. I've completed 150+ projects here for clients in 30+ countries, hold the Preferred Freelancer badge, and my clients' favorite thing about working with me is simple: I reply fast, I explain things in plain language, and I deliver files you can actually maintain after handover. Send me a message with what's slowing you down. I'll tell you honestly whether it's a quick fix or a proper build, and exactly how I'd approach it. menos -
