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.
