I take the repetitive back-office and data work off your plate — set up with automation, delivered by a managed team, and quality-checked before it reaches you. You get the result, not the overhead of finding, vetting, and managing offshore staff yourself. I'm an engineer by background, so I run this work the way an engineering team would — with tooling and automation where it helps — which makes it faster, more accurate, and cheaper to run over time. Every engagement is scoped, set up, and QA'd by me; you're never handed an unmanaged freelancer. What I handle: - Data entry, cleaning, de-duplication & CRM upkeep - Document & invoice processing - Research, list-building & data enrichment (on data you own) - E-commerce ops — product listings, catalogue & inventory - Inbox, calendar & general admin - Data prep & labelling for AI / automation projects Done safely: I work as a processor on data you own, under an NDA, GDPR-aware — I never buy or sell data. **Ways to work:** - A small, fixed-scope task first, so you can judge the quality at zero risk - An ongoing pod — a few hours a day or full-time — that just handles it And because I build software too, when a manual process is finally worth automating for good, I can build that — turning your back-office spend into real systems. Tell me the one task eating the most time this week, and I'll show you exactly how I'd take it off your plate.

I'm an ex-Microsoft engineer and full stack developer with extensive knowledge and experience of web, app, cloud, database and API development. I have an excellent understanding of Microsoft technologies including C#, Blazor, MAUI, Xamarin, ASP.NET Core, Azure, Open AI, SQL Server and web API. I have successfully delivered a number of commercial web, portal, API integration and app projects and happy to share examples . I have also recently completed a POC for an international company to understand how existing company data could be used within an AI RAG solution, accessed via a web (Blazor) portal, which was hosted on Azure. This has proved very popular with their clients and plans are being made to extend this into their live environment. If you need any further information, please get in touch. Thanks, Alex
