Versatile Full-Stack Engineer | AI-Driven Systems & Autonomous Software Innovator
William Hein
Innovative software engineer with over 6 years of hands-on experience delivering complex, high-performance systems across the tech landscape. Self-taught in a diverse array of programming languages including TypeScript, Go, Python, Dart, Swift, and PHP, I thrive on building robust, scalable solutions that push the boundaries of automation, AI, and real-time data processing.
My journey spans from developing real-time trading infrastructure for multi-exchange platforms, designing AI-augmented multi-agent systems that autonomously evolve trading algorithms, to crafting native macOS utilities and cross-platform mobile apps. I excel at architecting autonomous software capable of interacting reliably with messy, real-world systems—delivering innovative solutions in finance, blockchain, event management, and SaaS platforms.
As the founder and lead developer at Heitech.dk, I spearhead projects like Murph—an advanced B2B sales intelligence dashboard utilizing Next.js and TypeScript—and the Sentient Evolve engine, a multi-agent AI system that self-improves trading strategies through feedback loops and isolated Docker environments. I built high-frequency ingestion systems in Go, optimized for performance and safety, and developed a Chrome extension for automated trading that emulates human behavior to bypass sophisticated bot detection.
My expertise extends into blockchain integration, real-time NFT verification via XRP Ledger streams, community automation for 10,000+ users, and full-stack event ticketing platforms with QR-code entry validation and dynamic UI pipelines. I also develop tools for energy data management, security automation, and containerized deployments, always emphasizing security, reliability, and efficiency.
Driven by a passion for AI, cybersecurity, and emerging tech trends, I am a proactive problem-solver with a proven track record of translating complex ideas into practical, scalable products. Whether leading innovative startups, automating workflows, or pushing the frontiers of multi-agent AI, I bring a relentless curiosity and a commitment to excellence.
