Zimuzo E.

Senior Engineering Consultant @ Hecatoncheires

About

I've spent eight years building web and mobile applications for fintech, telecom, and iGaming companies. Most recently, I was at Betsson Group in Malta, where I developed casino features and micro-frontends deployed across multiple global brands. I work primarily with TypeScript and Node.js. My portfolio includes building mobile banking apps (Union Bank, GTBank), cross-sell widgets (Betsson), and payment provider integrations (Reloadly), usually in environments where high performance and regulatory compliance are equally critical. Recent work at Betsson included building gaming lobby components deployed across all casino brands, collaborating with enterprise architects to migrate from monolithic Angular to SSR-enabled web components, and leading a small team through the Euro 2024 product launches. Currently, I am building user-facing experiences for AI-native products where intelligence is core, not bolted on. This includes a multi-agent research system using LangGraph and local LLM inference, as well as a Node.js MCP server that exposes LinkedIn job search as a tool within Claude Desktop. I’m looking for senior engineering roles at product-led companies where I can leverage TypeScript and modern web technologies to solve complex problems. Feel free to reach out if you're working on something interesting. Note: BSc degree holds Anabin H+ recognition, eligible for the German Fast-Track Visa for Skilled Workers and EU Blue Card.
