If you have business data that needs to make sense, dashboards that need to work, and systems your team can rely on, you're in the right place. With 5+ years in data and revenue analytics, plus a background in accounting, I work across the full picture: understanding what your business actually needs, cleaning and analyzing the data, and building reporting and systems that are genuinely useful, not just nice to look at. My background is specifically in revenue management & operations, so I don't just report numbers, I look for what actually moves them. Every system I build is with an eye toward what increases revenue or reduces cost, not just what looks clean on a dashboard. What sets me apart: Most analysts can clean data or build a dashboard. I do the whole pipeline, and I understand the financial logic behind your numbers, not just how to visualize them. I also use AI tools like Claude to work faster and dig deeper, so you get better results in less time. The thinking and final output are always mine. What I can help with: ✔ Data cleaning — structuring messy datasets so your reporting is reliable (SQL, Power Query, Excel, from 470 rows to 1M+ records) ✔ Analysis & insights — surfacing what actually moves the needle for your business ✔ Dashboards — Power BI, Looker Studio, Google Sheets, with financial summaries your stakeholders can act on ✔ Systems & automation — calculators, trackers, Gantt charts, and automated workflows in Excel and Sheets A few things I've built: ✅ The full financial and operational foundation for a product line that scaled to $3M in quarterly revenue ✅ Dashboards across a 300+ hotel portfolio worth $100M+, including margin tracking and cash flow modeling ✅ Reporting and automated systems for clients across the US, UK, and UAE Tools Excel · Google Sheets · SQL · Python · Power BI · Tableau · DOMO · Google Apps Script · PowerPoint I like to understand the real problem before jumping to solutions.
