Available for long-term collaborations, agency partnerships, and complex technical projects. I’ve collaborated with international digital agencies, private companies, and teams delivering solutions for governmental and defense-related projects, working in environments where reliability, security, and professionalism are essential.

I build the data and automation systems businesses actually run on. 15 years on Freelancer.com, 1,000+ projects delivered, 600 five-star reviews. Most clients arrive with the same problem: the numbers live in five different places, nothing reconciles, and someone burns a week every month pulling it together by hand....I build the data and automation systems businesses actually run on. 15 years on Freelancer.com, 1,000+ projects delivered, 600 five-star reviews. Most clients arrive with the same problem: the numbers live in five different places, nothing reconciles, and someone burns a week every month pulling it together by hand. I clean it up, connect it, and automate what comes after. What I do: ✅ Data cleanup & processing — deduping, normalising and validating messy records at scale ✅ Multi-source integration — API, CSV and database syncs between the tools you already pay for ✅ Dashboards & reporting — Excel and Power BI dashboards that refresh themselves ✅ Workflow automation — n8n, Power Automate, Zapier, Google Apps Script, Excel VBA & macros ✅ Web scraping — structured data at volume, cleaned and delivered ready to use ✅ Web & e-commerce — WordPress, Shopify, Magento, WooCommerce, BigCommerce builds and migrations ✅ Amazon & eBay — listings, feeds and optimisation ✅ Mobile apps — Android and iOS, published and maintained I have a small team behind me, so capacity is rarely the constraint. Roughly one in three of my projects comes from a client who has hired me before, and that repeat rate is the part of my record I would point you to first. Send me the process that is taking too long. I will tell you honestly whether it is worth automating and what it would take. less -
