Senior product operator. Shipped 20+ products across crypto, fintech, and AI - including tokenisation infrastructure live with the Nairobi Securities Exchange, automated crime-detection tools deployed to a European national police force, and consumer apps with paying users on the App Store. I run a small senior team that takes projects from idea to shipped, revenue-generating product fast usually weeks, not quarters. Most of my Upwork work falls into three buckets: 1 - Idea validation and market research. Stakeholder interviews, competitive mapping, regulatory analysis, customer interview synthesis, build-vs-buy-vs-don't recommendations. Typical engagement: 1–2 weeks, fixed-price, you get a written report you can show your investors or board. 2 - MVP builds in crypto, fintech, and AI. AI integration via Anthropic and OpenAI APIs. Full-stack web and mobile, built fast using AI-native development workflows (Claude Code, Cursor, modern stacks). For deep on-chain engineering, custom smart contracts, novel cryptography, I bring in specialist blockchain engineers from my network. I ship the kind of MVP a real customer can use, not a clickable prototype. Typical engagement: 4–8 weeks, fixed-price. 3 - Compliance, intelligence, and investigation tooling. KYC/AML, transaction monitoring, blockchain forensics, regulatory dashboards. This is specialist work, I've built and deployed it for both private firms and government agencies.
